CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not press the accelera-
tor 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, press and
hold the “ENGINE START STOP” switch for more than 3 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.
