Subaru Seatbelt warning light and chime Guide
Your vehicle is equipped with a seatbelt warning device at the driver’s and passenger’s seats, as required by current safety standards.
Driver’s and front passenger’s seats
S03AE0114 With the ignition switch turned to the “ON” position, this device reminds the driver and front passenger to fasten their seatbelts by illuminating the warning lights in the locations indicated in the following illustration and sounding a chime.
Driver’s seat
Front passenger’s seat
When the ignition switch is turned to the “ON” position, the driver’s and/or front passenger’s warning light will illuminate, then it will blink for several seconds. If the seatbelt of the driver’s seat is not fastened, the warning chime may make a beep sound.
NOTE
- If the driver’s and/or front passenger’s seatbelt(s) are/is not fastened while driving, the seatbelt warning system operates as follows according to the vehicle speed.
- The warning light will illuminate when the vehicle speed is approximately 4 mph (6 km/h) or less.
- The warning light will blink, and the warning chime will make a beep sound when the vehicle speed is between approximately 4 mph (6 km/h) and 13 mph (20 km/h). The warning chime will stop when the vehicle stops.
- The warning light will blink, and the warning chime will sound
loudly when 15 seconds have elapsed when the vehicle speed is between approximately 4 mph (6 km/h) and 13 mph (20 km/h). - The warning light will blink, and the warning chime will sound
loudly when the vehicle speed is approximately more than 13 mph (20 km/h).
- The warning light will turn off and the warning chime will stop when the seatbelt is fastened.
If there is no passenger on the front passenger’s seat, the seatbelt warning system for the front passenger’s seat will be deactivated. The front passenger’s seatbelt warning system monitors whether or not there is a passenger on the front passenger’s seat.
CAUTION
Observe the following precautions. Failure to do so may prevent the
device from functioning correctly or cause the device to fail.
- Do not install any accessory such as a table or TV onto the seatback.
- Do not store a heavy load in the seatback pocket.
- Do not allow the rear seat occupant to place his/her hands or
legs on the front passenger’s seatback, or allow him/her to pull the seatback. - Do not use front seats with their backward-forward position and
seatback not being locked into place securely. If any of them are not locked securely, adjust them again. For adjusting procedure, refer to “Manual seat”.
If the seatbelt warning system for the front passenger’s seat does not function correctly (e.g., it is activated even when the front passenger’s seat is empty or it is deactivated even when the front passenger has not fastened his/her seatbelt), take the following actions.
- Ensure that no article is placed on the seat other than a child restraint system and its child occupant, although we strongly recommend that all children sit in the rear seat properly restrained.
- Ensure that there is no article left in the seatback pocket.
- Ensure that the backward-forward position and seatback of front passenger’s seat are locked into place securely by moving the seat back and forth.
If still the seatbelt warning system for front passenger’s seat does not function correctly after taking relevant corrective actions described above, immediately contact your SUBARU dealer for an inspection.

- Do not apply any strong impact to the rear seat.
- Do not fold the seatback forward when objects are on the
seat. - Do not spill liquid on the rear seat. If liquid is spilled, wipe it
off immediately. - Do not remove or disassemble the rear seat.
NOTE
- The seatbelt warning system of the rear seats detects if any of the seats are occupied by a passenger. Heavy cargo or large pets on the rear seats may result in the activation of the passenger seatbelt warning light and chime. Fastening the rear seatbelt prior to loading cargo or large pets will avoid activating the passenger seatbelt warning light and chime.
- When folding second- or third-row seats, ensure that the seats are empty prior to folding. Items caught between the seat bottom and seatback, when folded, may damage the seat surface or activate the passenger seatbelt warning light and chime.
If passengers in the rear seats do not fasten their seatbelts while the ignition switch is turned to the “ON” position, the seatbelt warning lights will illuminate or blink to indicate that their seatbelts are not fastened.
NOTE
- If the rear passenger’s seatbelt(s) are/is still not fastened while driving, the seatbelt warning system operates as follows according to the vehicle speed.
- The warning light will illuminate when the vehicle speed is approximately 4 mph (6 km/h) or less.
- When the vehicle speed is approximately between 4 mph (6 km/h) and 13 mph (20 km/h), the seatbelt warning lights will blink and a warning chime will sound. The chime will make a beep sound for 15 seconds, and it then will become louder and continue for 35 seconds. The warning light will blink for 50 seconds, then it will illuminate steadily and the chime will stop.
- The warning light will blink, and the beep will sound loudly for 35 seconds when the vehicle speed is approximately more than 13 mph (20 km/h). After 35 seconds, the blinking warning light willilluminate steadily and the chime will stop. The warning lights will continue to illuminate until their seatbelts are fastened.
- The warning light will turn off and the warning chime will stop when the seatbelt is fastened.
SRS airbag system warning light
WARNING
If the warning light exhibits any of the following conditions, immediately stop the vehicle in a safe place, and consult a SUBARU dealer.

- Flashing or flickering of the warning light
- No illumination of the warning light when the ignition switch is first turned to the “ON” position
- Continuous illumination of the warning light
- Illumination of the warning light while driving
For details about the components monitored by the warning light, refer to “SRS airbag system monitors”
Front passenger’s frontal airbag ON and OFF indicator lights
Front passenger’s frontal airbag ON indicator lights
Front passenger’s frontal airbag OFF indicator lights The front passenger’s frontal airbag ON and OFF indicator lights show you the status of the front passenger’s SRS frontal airbag. The indicators are located as shown in the illustration. When the ignition switch is turned to the “ON” position, both the ON and OFF indicator lights illuminate for 6 seconds during which time the system is checked. Following the system check, both indicators turn off for 2 seconds.
After that, one of the indicators illuminates depending on
the status of the front passenger’s SRS frontal airbag determined by the SUBARU advanced frontal airbag system monitoring. If the front passenger’s SRS frontal airbag is activated, the passenger’s frontal airbag ON indicator light will illuminate while the OFF indicator light will remain off. If the front passenger’s SRS frontal airbag is deactivated, the passenger’s frontal airbag ON indicator light will remain off while the OFF indicator light will illuminate. With the ignition switch turned to the “ON” position, if both the ON and OFF indicator lights remain illuminated or off simultaneously even after the system check period, the system is malfunctioning. Contact your SUBARU dealer immediately for an inspection.
CHECK ENGINE
warning light/Malfunction indicator light
CAUTION
If the CHECK ENGINE warning light illuminates while you are driving, have your vehicle checked/repaired by your SUBARU dealer as soon as possible. Continued vehicle operation without having the emission control system checked and repaired as necessary could cause
serious damage, which may not be covered by your vehicle’s warranty.
If this light illuminates steadily or blinks while the engine is running, it may indicate that there is at least one problem or potential problem somewhere in the emission control system.
If the light illuminates steadily
If the light illuminates steadily while driving or does not turn off after the engine starts, an emission control system malfunction has been detected. You should have your vehicle checked by an authorized SUBARU dealer immediately.
NOTE
This light also illuminates when the fuel filler cap is not tightened until it clicks. If you have recently refueled your vehicle, the cause of the CHECK ENGINE warning light/malfunction indicator light illuminating could be a loose or missing fuel filler cap. Remove the cap and retighten it until it clicks. Make sure nothing is interfering with the sealing of the cap. Tightening the cap will not make the CHECK ENGINE warning light turn off immediately. It may take several driving trips. If the light does not turn off, take your vehicle to your authorized SUBARU dealer immediately.
If the light is blinking
If the light is blinking while driving, an engine misfire condition has been detected which may damage the emission control system. To prevent serious damage to the emission control system, you should do the following.
- Reduce vehicle speed.
- Avoid hard acceleration.
- Avoid steep uphill grades.
- Reduce the amount of cargo, if possible.
- Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking and illuminate steadily after several driving trips. You should have your vehicle checked by an authorized SUBARU dealer immediately.
Charge warning light
If the light illuminates while driving or does not turn off after the engine starts, stop the engine at the first safe opportunity and check the drive belt. If the belt is loose, broken or if the belt is in good condition but the light remains illuminated, contact your nearest SUBARU dealer immediately.
Oil pressure warning light
If this light illuminates when the engine is running, it may indicate that the engine oil pressure is low and the lubricating system is not working properly. If the light illuminates while driving or does not turn off after the engine starts, stop the engine at the first safe opportunity and contact your nearest SUBARU dealer immediately.
CAUTION
Do not operate the engine with the oil pressure warning light illuminated. This may cause serious engine damage.
Engine low oil level warning light
This light illuminates when the engine oil level decreases to the lower limit. If the warning light illuminates, check the engine oil level on a level surface. When the engine oil level is not within the normal range, refill with engine oil. Refer to “Engine oil”P482. After adding or changing the engine oil, warm up the engine and stop it on a level surface, then start the engine after a lapse of 1 minute or more. Confirm that the warning light has turned off after the engine has started. If the warning light does not turn off after refilling the engine oil, or the light illuminates even though the engine oil level is within the
normal range, have the vehicle checked by a SUBARU dealer.
NOTE
- The oil level will be detected by the system just after turning the ignition switch to the “OFF” position. If the oil level is below the lower limit when the ignition switch is turned to the “ON” position, the engine low oil level warning light will turn on.
- When the vehicle is parked on a steep slope, the engine low oil level warning light may not illuminate even if the oil level is below the lower limit to avoid erroneous lighting.
Windshield washer fluid warning light
AT OIL TEMP warning light
If this light illuminates when the engine is running, it may indicate that the transmission fluid temperature is too hot. If the light illuminates while driving, immediately stop the vehicle in a safe place and let the engine idle until the warning light turns off.
Transmission control system warning
If the “AT OIL TEMP” warning light flashes after the engine has started, it may indicate that the transmission control system is not working properly. Contact your nearest SUBARU dealer for service immediately.
Rear differential oil temperature warning light
CAUTION
If the R.DIFF TEMP warning light illuminates, reduce vehicle speed
and stop the vehicle in a safe location as soon as possible. Continuing to drive with this light illuminated may damage the rear differential and other parts of the powertrain.
If this light illuminates when the engine is running, it may indicate that the rear differential oil temperature is too hot. If the light illuminates while driving, reduce vehicle speed and stop the vehicle in the nearest safe location. Park the vehicle for several minutes. After the light turns off, you can start driving. If the light does not turn off, contact the nearest SUBARU dealer for service.
NOTE
- If the tire pressures are not correct and/or the tires are not all the same size and brand, the rear differential will be heavily loaded when the vehicle is driven, resulting in an abnormally high oil temperature.
- The rear differential oil will deteriorate if its temperature increases enough for the rear differential oil temperature warning light to illuminate. It is advisable to have the rear differential oil replaced as soon as possible.
Low tire pressure warning light (U.S.- spec. models)
Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to continue to function properly. Should the warning light illuminate steadily
after blinking for approximately one minute, have the system inspected by your nearest SUBARU dealer as soon as possible.
WARNING
If this light does not illuminate briefly after the ignition switch is
turned on or the light illuminates steadily after blinking for approximately one minute, you should have your tire pressure monitoring system (TPMS) checked at a SUBARU dealer as soon as possible. If this light illuminates while driving, never brake suddenly and keep driving straight ahead while gradually reducing speed. Then slowly pull off the road to a safe place. Otherwise an accident involving
serious vehicle damage and serious personal injury could occur.
If this light still illuminates while driving after adjusting the tire pressure, a tire may have significant damage and a fast leak that causes the tire to lose air rapidly. If you have a flat tire, replace it with a spare tire as soon as possible.
When a spare tire is mounted or a wheel rim is replaced without the
original pressure sensor/transmitter being transferred, the Low tire pressure warning light will illuminate steadily after blinking for approximately one minute. This indicates the TPMS is unable to monitor all four road wheels. Contact your SUBARU dealer as soon as possible for tire and sensor replacement and/ or system resetting.
If the light illuminates steadily after blinking for approximately one minute, promptly contact a SUBARU dealer to have the system inspected.
CAUTION
The tire pressure monitoring system is NOT a substitute for manually checking tire pressure. The tire pressure should be checked periodically (at least monthly) using a tire gauge. After any change to tire pressure(s), the tire pressure monitoring system will not re-check tire inflation pressures until the vehicle is first driven more than 20 mph (32 km/h). After adjusting the tire pressures, increase the vehicle speed to at least 20 mph (32 km/h) to start the TPMS re-checking of the tire inflation pressures. If the tire pressures are now above the severe low pressure threshold, the low tire pressure warning light should turn off a few minutes later. Therefore, be sure to install the specified size for the front and rear tires.
ABS warning light
CAUTION
- If any of the following conditions occur, we recommend that you have the ABS repaired at the first available opportunity by your SUBARU dealer.
- The warning light does not illuminate when the ignition switch is turned to the “ON” position.
- The warning light illuminates when the ignition switch is turned to the “ON” position, but it does not turn off even after the vehicle is started.
- The warning light illuminates during driving.
- When the warning light is on (and the brake system warning light is off), the ABS function shuts down. However, the conventional brake system continues to operate normally.
The ABS warning light, Vehicle Dynamics Control warning light, and brake system warning light illuminate simultaneously if the EBD system malfunctions. For further details of the EBD system malfunction warning, refer to “Electronic Brake Force Distribution (EBD) system warning”.
NOTE
If the warning light behavior is as described in the following conditions, the ABS may be considered normal.
- The warning light illuminates when the ignition switch is turned to the “ON” position and turns off approximately 2 seconds after the engine has started.
- The warning light illuminates right after the engine is started but turns off immediately, remaining off.
- The warning light remains illuminated after the engine has been started, but it turns off while driving.
- The warning light illuminates during driving, but it turns off immediately and remains off.
When driving with an insufficient battery voltage, such as when the engine is jump started, the ABS warning light may illuminate. This is due to the low battery voltage and does not indicate a malfunction. When the battery becomes fully charged, the light will turn off.
Brake system warning light
This light illuminates with the parking brake applied while the ignition switch is in the “ON” position. It turns off when the parking brake is fully released.
WARNING
- Driving with the brake system warning light on is dangerous. This indicates your brake system may not be working properly. If the light remains illuminated, have the brakes inspected by a SUBARU dealer immediately.

- The electronic parking brake indicator light may flash immediately after the engine is started. However, it is not malfunctioning if the indicator light turns off after the electronic parking brake is released.
- The electronic parking brake indicator light may flash after the electronic parking brake is frequently applied and released. However, the electronic parking brake system is not malfunctioning if the light turns off for a short period of time.
The electronic parking brake indicator light flashes when the electronic parking brake system is malfunctioning. If the indicator light flashes, promptly park in a safe location as soon as possible and contact your SUBARU dealer. The electronic parking brake indicator light remains illuminated when the parking brake cannot be released even if the parking brake switch is pushed. For details, refer to “Electronic parking brake”.
Parking brake apply inhibit warning
The electronic parking brake indicator light flashes for 10 seconds and a chirp sound will be heard if the parking brake switch is operated when the parking brake cannot be applied.
Frequent operation warning
The electronic parking brake indicator light flashes for 10 seconds and a chirp sound will be heard if the parking brake switch is operated too frequently. In this case, the operation of the parking brake switch is restricted to protect the electronic parking brake system.
NOTE
Wait until the indicator light turns off.
Auto Vehicle Hold indicator light
CAUTION
If the Auto Vehicle Hold indicator light does not illuminate even when
“Auto Vehicle Hold (AVH)” is touched to activate the Auto Vehicle Hold function, the electronic parking brake system may be malfunctioning. This indicator light illuminates when the Auto Vehicle Hold is activated. This indicator blinks while the vehicle is stopped by the Auto Vehicle Hold function. For details, refer to “Auto Vehicle Hold function”.
Low fuel warning light
The low fuel warning light illuminates when the tank is nearly empty, at approximately 2.6 US gal (10.0 liters, 2.2 Imp gal). It only operates when the ignition switch is in the “ON” position.
CAUTION
Promptly put fuel in the tank whenever the low fuel warning light illuminates. Engine misfires as a result of an empty tank could cause damage to the engine.
Door open warning light
The warning light illuminates if any door or the rear gate is not fully closed. This function is effective even if the ignition switch is in the “OFF” or “ACC” position. Only the open doors are indicated by the warning lights. Always make sure this light is not illuminated before you start to drive.
All-Wheel Drive warning light
This light blinks if the vehicle is driven with tires of differing diameters fitted on the wheels or with an excessively low air pressure in any of the tires.
WARNING
If the AWD warning light flashes, promptly park in a safe location then check whether all four tires are the same diameter and whether any of the tires has a puncture or has lost air pressure for some other reason. Continuing to drive with the AWD warning light flashing can lead to powertrain damage.
NOTE
If the temporary spare tire is used, the AWD warning light may flash. Use of the temporary spare tire should therefore be restricted to the minimum time necessary. Replace the temporary spare tire with a conventional tire as soon as possible.
Power steering warning light
While the engine is running, this warning light illuminates when a malfunction has been detected in the electric power steering system.
CAUTION
When the power steering warning light is illuminated, there may be more resistance when the steering wheel is operated. Drive carefully to the nearest SUBARU dealer and have the vehicle inspected immediately.
2024 Subaru Ascent Specs, Price, Features, Mileage and Review
NOTE
If the steering wheel is operated in the following ways, the power steering control system may temporarily limit the power assist in order to prevent the system components, such as the control computer and drive motor, from overheating.
- The steering wheel is operated frequently and turned sharply while the vehicle is maneuvered at extremely low speeds, such as while frequently turning the steering wheel during parallel parking.
- The steering wheel remains in the fully turned position for a long period of time.
At this time, there will be more resistance when steering. However this is not a malfunction. Normal steering force will be restored after the steering wheel is not operated for a while and the power steering control system has an opportunity to cool down. However, if the power steering is operated in a non-standard way which causes power assist limitation to occur too frequently, that may result in a malfunction of the power steering control system.
Vehicle Dynamics Control warning light/Vehicle Dynamics Control operation indicator light
Vehicle Dynamics Control warning light
CAUTION
The Vehicle Dynamics Control system provides its ABS control through the electrical circuit of the ABS. Accordingly, if the ABS is inoperative, the Vehicle Dynamics Control system becomes unable to provide ABS control. As a result, the Vehicle Dynamics Control system also becomes inoperative, causing the warning light to illuminate. Although both the Vehicle Dynamics Control system and ABS are inoperative in this case, the ordinary functions of the brake system are still available. You will be safe while driving with this condition, but drive carefully and have your vehicle checked at a SUBARU dealer as soon as possible.
NOTE
- If the electrical circuit of the Vehicle Dynamics Control system itself malfunctions, the warning light only illuminates. At this time, the ABS (Anti-lock Brake System) remains fully operational.
- The warning light illuminates when the electronic control system of the ABS/Vehicle Dynamics Control system malfunctions.
- The Vehicle Dynamics Control warning light, ABS warning light, and brake system warning light illuminate simultaneously if the EBD system malfunctions. For further details of the EBD system malfunction warning, refer to “Electronic Brake Force Distribution (EBD) system warning”.
