■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 resu lting 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 cir-
cumstance may lead to an accident, re sulting 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 succes-
sion. ( P. 5 3 3 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause lo ss of steering or braking control, but the
power assist to these systems will be lost. Th is 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.
