WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay re sponse in an emergency, resulting in an accident.●
The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement. ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
