CAUTION
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving
If the vehicle is coasting without engine power, for example if the engine
stalls, do not open a door or operate the locks until the vehicle is completely
stopped in a safe condition. Driving with the steering locked 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.
