STOP” switch is operated again.
Steering lock release
Steering lock motor overheat prevention
If the engine is started and stopped repeatedly in a short time, operation of

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 automati-
cally turn off. However, this function cannot entirely prevent battery dis-
charge. 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.
Manual transmission
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, the

running.

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 is coasting without engine power, for example if the engine
stalls, do not open a door or operate the locks until the vehicle is completely
stopped in a safe condition. Driving with the steering locked 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 IGNI-
TION 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 the engine
checked immediately.
“ENGINE START STOP” switch operation
If you feel something catching or sense irregular resistance when operating
the “ENGINE START STOP” switch, then there may be a malfunction. Imme-
diately contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
