Seatback angle
To recline the seatback:
1. Lean forward slightly and lift up the seatback lever.
2. Carefully lean back on the seat and adjust the seatback to the position
you desire.
3. Release the lever and make sure the seatback is locked in place. (The lever
MUST return to its original position for
the seatback to lock.)
Reclining seatback
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protection of
your restraint system (seat belts and air
bags) is greatly reduced by reclining your
seatback.
WARNING
NEVER ride with a reclined seatback
when the vehicle is moving.
Riding with a reclined seatback
increases your chance of serious or fatal
injuries in the event of a collision or
sudden stop.
Drivers and passengers should ALWAYS
sit well back in their seats, properly
belted, and with the seatbacks upright. Seat belts must be snug against your
hips and chest to work properly. When
the seatback is reclined, the shoulder
belt cannot do its job because it will not
be snug against your chest. Instead,
it will be in front of you. During an
accident, you could be thrown into the
seat belt, causing neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger’s hips will slide under the lap belt or the
passenger’s neck will strike the shoulder belt.
ODN8039004
Seat cushion height
To change the height of the seat cushion: •
Push down on the lever several times,
to lower the seat cushion.
• Pull up on the lever several times, to
raise the seat cushion.

Seat Warmers and Air Ventilation
Seats
Seat warmers (if equipped)
Seat warmers are provided to warm the
seats during cold weather.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers: • Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats:
Never use a solvent such as paint
thinner, benzene, alcohol or gasoline to
clean the seats.
Do not place heavy or sharp objects on
seats equipped with seat warmers.
Do not change the seat cover. It
may damage the seat warmer or air
ventilation system.

NOTICE
To prevent damage to the air ventilation
seat: • Use the air ventilation seat ONLY
when the climate control system
is on. Using the air ventilation seat
for prolonged periods of time with
the climate control system off could
cause the air ventilation seat to malfunction.
• NEVER use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Avoid spilling liquids on the surface
of the front seats and seatbacks;
this may cause the air vent holes
to become blocked and not work
properly.
• Do not place materials such as
plastic bags or newspapers under
the seats. They may block the air
intake causing the air vents to not
work properly.
• Do not change the seat covers. It may
damage the air ventilation seat.
