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,
push and hold the "ENGINE START STOP" switch for more than 3 sec-
onds.
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 the battery from being discharged
Do not leave the "ENGINE START STOP" switch in ACCESSORY or
IGNITION ON mode for long periods of time 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.
