Performing the following operations when carrying the electronic key on your person starts the engine or changes “ENGINE START STOP” switch modes.
- Starting the engine
Check that the parking brake is set.
Check that the shift lever is set
in “P”.

depress the brake pedal.
The “ENGINE START STOP” switch indicator turns green.

Press the “ENGINE START STOP” switch.
The engine can be started from any “ENGINE START STOP” switch mode.
Continue depressing the brake pedal until the engine is completely started. The engine will crank until it starts or for up to 30 seconds, whichever is less.
- Changing “ENGINE START STOP” switch mode
Modes can be changed by pressing the “ENGINE START STOP” switch with the brake pedal released. (The mode changes each time the switch is pressed.)

3. IGNITION ON mode
All electrical components can be used.

*: If the shift lever is in a position other than “P” when turning off the engine, the “ENGINE START STOP” switch will be turned to ACCESSORY mode, not to OFF.
- When the steering lock cannot be released

The green indicator light on the “ENGINE START STOP” switch will flash and a message will be shown on the multi-information display (TFT type only). To free it, press the “ENGINE START STOP” switch while turning the steering wheel slightly in either direction.
- If the engine does not start
The engine immobilizer system may not have been deactivated. Contact your Toyota dealer.
- When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your Toyota dealer immediately.
- Auto power off function

- Note for the entry function
CAUTION
- When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
- 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 START STOP” switch for more than 2 seconds, or press it briefly 3 times or more in succession. However, do not touch the “ENGINE START STOP” 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.
NOTICE
- To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION ON mode for long periods without the engine running.
- When starting the engine
• Do not race a cold engine.
• If the engine becomes difficult to start or stalls frequently, have your vehicle checked by your Toyota dealer immediately.
