4-2. Driving procedures
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accel-
erator 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 2 seconds, or press it briefly 3 times or more
in succession. (→P. 4 5 9 )
However, do not touch the engine switch while driving except in an emergency.
Turning the engine off while driving will not cause loss of steering or braking con-
trol, 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.
