To prevent the steering lock motor from overheating, the motor may be sus-
pended 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.

■ Operation of the engine switch
When operating the engine switch, one short, firm press is enough. If the
switch is pressed improperly, the engi ne may not start or the engine switch
mode may not change. It is not necessary to press and hold the switch.
■ If the smart entry & start system has been deactivated in a customized
setting
P. 516
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 engine failure occurs while the vehicle is moving, 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 3 seconds, or press it briefly
3 times or more in succession. ( P. 421)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine switch 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.
