Anti-lock Brake System (ABS)

WARNING
An Anti-Lock Braking System (ABS) or an Electronic Stability Control (ESC) system will not prevent accidents
due to improper or dangerous driving maneuvers. Even though vehicle control is improved during emergency braking, always maintain a safe distance between you and objects ahead of you. Vehicle speeds should always be reduced during extreme road conditions. The braking distance for cars equipped with ABS or ESC may be longer than for those without these systems in the following road conditions.
Drive your vehicle at reduced speeds during the following conditions:

  • Rough, gravel, or snow-covered roads.
  • On roads where the road surface is pitted or has a different surface height.
  • Tire chains are installed on your vehicle.
    The safety features of an ABS or ESC-equipped vehicle should not be tested by high-speed driving or cornering. This could endanger the safety of yourself or others.
    ABS is an electronic braking system that helps prevent a braking skid. ABS allows the driver to steer and brake at the same time.

Using ABS
To obtain the maximum benefit from your ABS in an emergency situation,
do not attempt to modulate your brake pressure, and do not try to pump your brakes. Depress your brake pedal as hard as possible.
When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ABS is active.
ABS does not reduce the time or distance it takes to stop the vehicle.
Always maintain a safe distance from the vehicle in front of you.
ABS will not prevent a skid that results from sudden changes in direction, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe speed for the road and weather conditions.
ABS cannot prevent a loss of stability. Always steer moderately when braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road.
On loose or uneven road surfaces, the operation of the anti-lock brake system may result in a longer stopping distance than for vehicles equipped with a conventional brake system.
The ABS warning light ( ) will stay on for several seconds after the ignition switch is in the ON position. During that time, the ABS will go through self-diagnosis and the light will go off if everything is normal. If the light stays on, you may have a problem with your ABS. Contact an authorized HYUNDAI dealer as soon as possible.

WARNING
If the ABS warning light ( ) is on and stays on, you may have a problem with the ABS. Your power brakes will work normally. To reduce the risk of serious injury or death, contact your HYUNDAI dealer as soon as possible.

CAUTION
When you drive on a road having poor traction, such as an icy road, and apply your brakes continuously, the ABS will be active continuously and the ABS warning light ( ) may illuminate. Pull your car over to a safe place and turn the engine off.
Restart the engine. If the ABS warning light is off, then your ABS system is normal.
Otherwise, you may have a problem with your ABS system. Contact an authorized HYUNDAI dealer as soon as possible.

Information
When you jump-start your vehicle because of a drained battery, the ABS warning light ( ) may turn on at the same
time. This happens because of the low battery voltage. It does not mean your ABS is malfunctioning. Have the battery recharged before driving the vehicle.

Electronic Stability Control (ESC) (if equipped)

Hyundai Elantra 2023 Anti-lock Brake System (ABS) and ISG (Idle Stop and Go) System User Guide 1

The Electronic Stability Control (ESC) system helps to stabilize the vehicle during cornering maneuvers. ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicle’s brakes and intervenes in the engine management system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.

WARNING
Never drive too fast for the road conditions or too quickly when cornering. The ESC system will not prevent accidents.
Excessive speed in turns, abrupt maneuvers, and hydroplaning on wet surfaces can result in severe accidents.

ESC operation

ESC ON condition
When the ignition switch is in the
ON position, the ESC, and the ESC
OFF indicator lights illuminate for approximately three seconds. After both lights go off, the ESC is enabled.

When operating
When the ESC is in operation, the ESC indicator light blinks:

  • When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ESC is active.
  •  When the ESC activates, the engine may not respond to the accelerator as it does under routine conditions.
  •  If the Cruise Control is in use when the ESC activates, the Cruise Control automatically disengages. The Cruise Control can be reengaged when the road conditions allow. See “Cruise Control System” later in this chapter. (if equipped)
  •  When moving out of the mud or driving on a slippery road, the engine RPM (revolutions per minute) may not increase even if you press the accelerator pedal deeply. This is to maintain the stability and traction of the vehicle and does not indicate a problem.

ESC OFF condition
To cancel ESC operation:

  • State 1
    • Press the ESC OFF button briefly. The ESC OFF indicator light and message
    • “Traction Control disabled” will illuminate. In this state, the traction control function of ESC (engine management) is disabled, but the brake control function of ESC (braking management) still operates.
  • State 2
    • Press and hold the ESC OFF button continuously for more than 3 seconds. The ESC OFF indicator light and the message “Traction and Stability Control disabled” illuminates and a warning chime sounds. In this state, both the traction control function of ESC (engine management) and the brake control function of ESC (braking management) are disabled.
    • If the ignition switch is placed in the LOCK/OFF position when ESC is off, ESC remains off. Upon restarting the engine, the ESC will automatically turn on again.

Indicator lights

When the ignition switch is placed in the ON position, the ESC indicator light illuminates, and then goes off if the ESC system is operating normally.
The ESC indicator light blinks whenever the ESC is operating.
If the ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on when the ESC is turned off.

WARNING
When the ESC is blinking, this indicates the ESC is active:
Drive slowly and NEVER attempt to accelerate. NEVER turn the ESC off while the ESC indicator light is blinking or you may lose control of the vehicle resulting in an accident.

NOTICE
Driving with wheels and tires of different sizes may cause the ESC system to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive a vehicle with different-sized wheels and tires installed.

ESC OFF usage
When Driving The ESC OFF mode should only be used briefly to help free the vehicle if stuck in the snow by temporarily stopping the operation of the ESC to maintain wheel torque. To turn the ESC off while driving, press the ESC OFF button while driving on a flat road surface.

NOTICE
To prevent damage to the transmission:

  • Do not allow wheel(s) of one axle to To prevent damage to the transmission: 􀀁􀀂 Do not allow wheel(s) of one axle to
  • When operating the vehicle on a dynamometer, make sure the ESC is turned off (ESC OFF light illuminated).

Information
Turning the ESC off does not affect ABS or standard brake system operation.

Vehicle Stability Management (VSM) (if equipped)

The Vehicle Stability Management (VSM) is a function of the Electronic Stability Control (ESC) system. It helps ensure the vehicle stays stable when accelerating or braking suddenly on wet, slippery, and rough roads where traction over the four tires can suddenly become uneven.

WARNING
Take the following precautions when using Vehicle Stability Management (VSM):

  • ALWAYS check the speed and the distance to the vehicle ahead. The VSM is not a substitute for safe driving practices.
  •  Never drive too fast for the road conditions. The VSM system will not prevent accidents. Excessive speed in bad weather, and slippery and uneven roads can result in severe accidents.

VSM operation
VSM ON condition

The VSM operates when:

  • The Electronic Stability Control (ESC) is on.
  • Vehicle speed is approximately above 9 mph (15 km/h) on curve roads.
  • Vehicle speed is approximately above 12 mph (20 km/h) when the vehicle is braking on rough roads.

When operating
When you apply your brakes under conditions that may activate the ESC, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your VSM is active.

NOTICE
The VSM does not operate when:

  • Driving on a banked road such as gradient or incline.
  • Driving rearward.
  • ESC OFF indicator light is on.
  • EPS (Electric Power Steering)

WARNING
If the ESC indicator light ( ) or EPS warning light ( ) stays on or blinks, your vehicle may have a malfunction with the VSM system. When the warning light illuminates, have your vehicle checked by an authorized HYUNDAI dealer as soon as possible. Driving with wheels and tires of different sizes may cause the ESC system to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive a vehicle with different-sized tires and wheels installed.

Hill-Start Assist Control (HAC) (if equipped)

The Hill-Start Assist Control (HAC) helps prevent the vehicle from rolling backward when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 2 seconds and releases the brake after 2 seconds or when the accelerator pedal is depressed.

WARNING
Always be ready to depress the accelerator pedal when starting off on an incline. The HAC activates only for approximately 2 seconds.

NOTICE

  •  The HAC does not operate when  the shift button is in P (Park) or N (Neutral)
  •  The HAC activates even though the ESC (Electronic Stability Control) is off but does not activate when the ESC has malfunctioned.

Good Braking Practices

WARNING
Whenever leaving the vehicle or parking, always come to a complete stop and continue to depress the brake pedal. Move the shift button into P
(Park) position, then apply the parking brake, and place the ignition switch in the LOCK/OFF position.
Vehicles parked with the parking brake not applied or not fully engaged may roll inadvertently and may cause injury to the driver and others. ALWAYS apply the parking brake before exiting the vehicle.
Wet brakes can be dangerous! The brakes may get wet if the vehicle is driven through standing water or if it
is washed. Your vehicle will not stop as quickly if the brakes are wet. Wet brakes may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes lightly until the braking action returns to normal, taking care to keep the vehicle under control at all times. If the braking action does not return to normal, stop as soon as it is safe to do so and call
an authorized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting on the brake pedal. Even light, but constant pedal pressure can result in the brakes overheating, brake wear, and possibly even brake failure.
If a tire goes flat while you are driving, apply the brakes gently and keep the vehicle pointed straight ahead while you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road and stop in a safe location.
Keep your foot firmly on the brake pedal when the vehicle is stopped to prevent the vehicle from rolling forward.

ISG (Idle Stop and Go) system

The Idle Stop and Go (ISG) system automatically and temporarily shuts down the engine when the vehicle is stopped and idling to help improve fuel efficiency and reduce exhaust gas emissions. (for example, red stop lights, stop signs, and traffic jams).
The engine is automatically started upon satisfying the starting conditions.
The ISG system is always active when the engine is running.

Information
When the engine is automatically started by the ISG system, some warning lights (for example, ABS, ESC, ESC OFF, EPS, and parking brake warning light) may illuminate for a few seconds due to the low battery voltage. However, it does not indicate a malfunction with the ISG system.
