Lexus ES350 2022 Engine Ignition Switch User Manual

Introduction

The premium car subsidiary of the Japanese carmaker Toyota, Lexus, produces the Lexus ES350 2022, a sedan. I am unable to supply you with specific information regarding the Lexus ES350 2022 model’s engine ignition switch, but I can provide you information about general engine ignition systems. An essential part of a car’s ignition system is the engine ignition switch. By regulating the flow of electrical current to the engine’s ignition system, it primarily serves to start and stop the engine. The switch’s “ON” position permits electrical current to flow to the ignition coil, spark plugs, and fuel injectors, among other parts of the ignition system.

In modern vehicles, ignition switches are often integrated into the ignition lock cylinder, which is the part where the key is inserted. However, some newer models are equipped with push-button start systems, eliminating the need for a physical key. The specific features and functionalities of the engine ignition switch can vary depending on the vehicle and its manufacturer. Some vehicles may have additional features integrated into the ignition switch, such as keyless entry or remote start capabilities. If you require more detailed information about the engine ignition switch of the Lexus ES350 2022, I recommend reaching out to a Lexus dealership or referring to the vehicle’s owner’s manual for accurate and up-to-date information.

Automatic engine shut off feature

• The vehicle is equipped with a feature that automatically shuts off the engine when the shift lever is in P with the engine running for an extended period.
  The engine will automatically shut off after approximately 1 hour if it has been left running while the shift lever is in P.
  The timer for the automatic engine shut off feature will reset if the brake pedal is depressed or if the shift lever is in a position other than P.
  After the vehicle is parked, if the door is locked with the door lock switch
  ( P.96) from the inside or the mechanical key from the outside, the automatic engine shut off feature will be disabled. The timer for the automatic engine shut off feature will be re-enabled if the driver’s door is opened.

WARNING
Stopping the engine in an emergency

• If you want to stop the engine in an emergency while driving the vehicle, press and hold the engine switch for more than 2 seconds, or press it briefly 3 times or more in succession.
  However, do not touch the engine switch while driving except in an emergency. Turning the engine off while driving will not cause loss of steering or braking control, but the power assist to these systems will be lost. This will make it more difficult to steer and brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
• If the engine switch is operated while the vehicle is running, a warning message will be shown on the multi-information display and a buzzer sounds.
  When restarting the engine after an emergency shutdown, shift the shift lever to N and press the engine switch shortly and firmly.

When parking
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle and may lead to an accident caused by light-headedness, or may lead to death or a serious health hazard.

• If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the engine.
  Do not leave the vehicle with the engine running for a long time. If such a situation cannot be avoided, park the vehicle in an open space and ensure that exhaust fumes do not enter the vehicle interior.
  Do not leave the engine running in an area with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the engine is running, exhaust gases may collect and enter the vehicle.

Changing engine switch modes
Modes can be changed by pressing the engine switch with the brake pedal released. (The mode changes each time the switch is pressed.)

1. Off*
   The emergency flashers can be used.
2. ACCESSORY mode
   Some electrical components such as the audio system can be used.
   “ACCESSORY” will be displayed on the meter.
3. IGNITION ON mode
   All electrical components can be used.
   “IGNITION ON” will be displayed on the meter.

If the shift lever is in a position other than P when turning off the engine, the engine switch will be turned to ACCESSORY mode, not to off.

Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON mode (the engine is not running) for more than an hour with the shift lever in P, the engine switch will automatically turn off. However, this function cannot entirely pre-vent the battery discharge. Do not leave the vehicle with the engine switch in ACCES-SORY or IGNITION ON mode for long periods of time when the engine is not running.

When stopping the engine with the shift lever in a position other than P

If the engine is stopped with the shift lever in a position other than P, the engine switch will not be turned off but instead be turned to ACCESSORY mode. Perform the following procedure to turn the switch off:

1. If the parking brake is in manual mode, set the parking brake.
2. Shift the shift lever to P.
3. Check that “Turn Power Off” is displayed on the multi-information dis-play and then press the engine switch once.
4. Check that “Turn Power Off” on the multi-information display is turned off.

NOTICE
To prevent battery discharge

Do not leave the engine switch in ACCESSORY or IGNITION ON mode for long periods of time without the engine running.
If “ACCESSORY” or “IGNITION ON” is displayed on the meter, the engine switch is not off.
Exit the vehicle after turning the engine switch off.

NOTICE

• Do not stop the engine when the shift lever is in a position other than P. If the engine is stopped in another shift lever position, the engine switch will not be turned off but instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY mode, battery discharge may occur.
