Front Seats
The front seat can be adjusted by using
the control switches located on the
outside of the seat cushion. Before
driving, adjust the seat to the proper
position so that you can easily control
the steering wheel, foot pedals and
controls on the instrument panel.
WARNING
Take the following precautions when
adjusting your seat:
• NEVER attempt to adjust the seat
while the vehicle is moving. The seat
could respond with unexpected
movement and may cause loss
of vehicle control resulting in an
accident.
• Do not place anything under the
front seats. Loose objects in the
driver’s foot area could interfere
with the operation of the foot pedals,
causing an accident.
• Do not allow anything to interfere
with the normal position and proper
locking of the seatback.
• Do not place a cigarette lighter on
the floor or seat. When you operate
the seat, gas may exit out of the
lighter causing a fire.
• Use extreme caution when picking
up small objects trapped under the
seats or between the seat and the
center console. Your hands might be
cut or injured by the sharp edges of
the seat mechanism.
• If there are occupants in the rear
seats, be careful while adjusting the
front seat position.
• Make sure that the seat is locked in
place after the adjustment. If not,
the seat might move unexpectedly
resulting in an accident.
CAUTION
To prevent injury:
• Do not adjust your seat while
wearing your seat belt. Moving the
seat cushion forward may cause
strong pressure on your abdomen.
• Do not allow your hands or fingers to
get caught in the seat mechanisms
while the seat is moving.

• Do not adjust the seats longer than
necessary when the vehicle is turned
off. This may result in unnecessary
battery drain.

the same time. This may result in an
electrical malfunction.
