Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.

• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign

■Eco-friendly driving
 P.85
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 accelera-
tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera- tor 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 a difficulty in
operating the pedals. Make sure to
operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress
the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay
response in an emer gency, 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. Even though
the vehicle is equipped with the
Acoustic Vehicle Alerting System,
drive with care as pedestrians in the
vicinity may still not notice the vehicle if
the surrounding area is noisy.
