Toyota Sienna 2010-2025 Owners Manual / Driving / Driving procedures / Engine (ignition) switch (vehicles with a smart key system) / 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:

Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the engine switch is illuminated in amber and then press the engine switch once.
Check that the indicator on the engine switch is 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 prevent battery discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNITION ON mode for long periods of time when the engine is not running.

Conditions affecting operation

Note for the entry function

If the engine does not start

The engine immobilizer system may not have been deactivated. Contact your Toyota dealer.

Steering lock

After turning the engine switch off and opening and closing the doors, the steering wheel will be locked due to the steering lock function.

The green indicator light on the engine switch will flash and a message will be shown on the multi-information display.

Press the engine switch while turning the steering wheel left and right.

Steering lock motor overheating prevention

To prevent the steering lock motor from overheating, the motor may be suspended if the engine is turned on and off repeatedly in a short period of time.

In this case, refrain from operating the engine. After about 10 seconds, the steering lock motor will resume functioning.

When the engine switch indicator flashes in amber

The system may be malfunctioning. Have the vehicle inspected by your Toyota dealer immediately.

Operation of the engine switch

When operating the engine switch, one short, firm press is enough. If the switch is pressed improperly, the engine may not start or the engine switch mode may not change. It is not necessary to press and hold the switch.
If attempting to restart the engine immediately after turning the engine switch off, the engine may not start in some cases. After turning the engine switch off, please wait a few seconds before restarting the engine.

WARNING

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.

Caution while driving

If the vehicle begins to slide due to engine failure or other circumstances, do not lock or open the doors until the vehicle reaches a safe and complete stop. Activation of the steering lock in this circumstance may lead to 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 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.

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 the indicator on the engine switch is illuminated, the engine switch is not off. When exiting the vehicle, always check that the engine switch is off.
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.

When starting the engine

Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.

Symptoms indicating a malfunction with the engine switch

If the engine switch seems to be operating somewhat differently than usual, such as the switch sticking slightly, there may be a malfunction.

Contact your Toyota dealer immediately.
