Safety notes
G
WARNING
All seat adjustments, as well as fastening
of seat belts, must be done before the
vehicle is operated. G
WARNING
When adjusting the seat, make sure no one
becomes trapped.
Do not adjust the driver’s seat while
driving. Adjusting the seat while driving
could
cause the driver to lose control of the
vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined
position as this can be dangerous. You
could slide under the seat belt in a
collision. If you slide under the seat belt,
it could apply force at the abdomen or neck,
potentially causing serious or fatal
injuries. The seat backrest and seat belts
provide the best restraint when the wearer
is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as
possible with the driver still able to
operate the controls properly.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Observe the notes on the air bag system. G
WARNING
Children 12 years old and under must be

obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats*
or
carpets in the footwell, make sure the
pedals still have sufficient clearance.

Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and lead to death.

(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while
driving, have the cause determined and
