Toyota 4Runner: Engine (ignition) switch (vehicles with a smart key system)

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.

Firmly depress the brake pedal.

The “ENGINE START STOP” switch indicator will turn green. If the indicator does not turn green, the engine cannot be started.

Press the “ENGINE START STOP” switch.

The engine will crank until it starts or for up to 30 seconds, whichever is less.

Continue depressing the brake pedal until the engine is completely started.

The engine can be started from any “ENGINE START STOP” switch mode.

Stopping the engine

Stop the vehicle.

Shift the shift lever to P.

Set the parking brake.

Press the “ENGINE START STOP”
switch.

Release the brake pedal and
check that the indicator on the “ENGINE START STOP” switch is off.

Changing “ENGINE START STOP” switch modes

Modes can be changed by pressing the “ENGINE START STOP” switch with 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.

The “ENGINE START STOP” switch indicator turns amber.

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

The “ENGINE START STOP” switch indicator turns amber.

*: 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 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 START STOP” 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 START STOP” switch is illuminated in amber and then press the “ENGINE START STOP” switch once.

Check that the indicator on the
“ENGINE START STOP” 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 START STOP” switch will automatically turn off.

However, this function cannot entirely prevent battery discharge. Do not leave the vehicle with the “ENGINE START STOP” switch in ACCESSORY or IGNITION ON mode for long periods of time when the engine is not running.

Operation of the “ENGINE START STOP” switch

When operating the “ENGINE START STOP” switch, one short, firm press is enough. If the switch is pressed improperly, the engine may not start or the “ENGINE START STOP” switch mode may not change. It is not necessary to press and hold the switch.

Conditions affecting operation

Note for the entry function

If the engine does not start

The engine immobilizer system may not have been deactivated.

Steering lock

After turning the “ENGINE START STOP” switch off and opening and closing the doors, the steering wheel will be locked due to the steering lock function.

Operating the “ENGINE START STOP” switch again automatically cancels the steering lock.

When the steering lock cannot be released

The green indicator light on the “ENGINE START STOP” switch will flash. Press the “ENGINE START STOP” switch again 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 START STOP” switch indicator flashes in amber

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

If the electronic key battery is depleted

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.

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 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 of time without the engine running.

• If the indicator on the “ENGINE START STOP” switch is illuminated, the “ENGINE START STOP” switch is not off. When exiting the vehicle, always check that the “ENGINE START STOP” 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 START STOP” 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 START STOP” switch

If the “ENGINE START STOP” seems to be operating somewhat differently than usual, such as the switch sticking slightly, there may be a malfunction.

Contact your Toyota dealer immediately.
