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.

blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.

Seat BeltS
This section describes how to use the
seat belts properly. It also describes
some of the things to avoid when using
seat belts.
Seat Belt Safety Precautions
Always fasten your seat belt and make
sure all passengers have fastened their
seat belts before starting any trip. Air
bags are designed to supplement the
seat belt as an additional safety device,
but they are not a substitute. Most states
require all occupants of a vehicle to wear
seat belts.
WARNING
Seat belts must be used by ALL
passengers whenever the vehicle is
moving. Take the following precautions
when adjusting and wearing seat belts:
• ALWAYS properly restrain children
under age 13 in the rear seats.
• NEVER allow children to ride in the
front passenger seat. If a child age 13
or older must be seated in the front
seat, move the seat as far back as
possible and properly restrain them
in the seat.
• NEVER allow an infant or child to be
carried on an occupant’s lap.
• NEVER ride with the seatback
reclined when the vehicle is moving.
• Do not allow children to share a seat
or seat belt.
• Do not wear the shoulder belt under
your arm or behind your back.
• Always wear both the shoulder
portion and lap portion of the lap/
shoulder belt.
• Do not use the seat belt if it is
twisted. A twisted seat belt will not
protect you properly in an accident.
• Do not use a seat belt if the webbing
or hardware is damaged. •
Do not latch the seat belt into the
buckles of other seats.
• NEVER unfasten the seat belt
while driving. This may cause loss
of vehicle control resulting in an
accident.
• Make sure there is nothing in the
buckle interfering with the seat belt
latch mechanism. This may prevent
the seat belt from fastening securely.
• No modifications or additions
should be made by the user which
will either prevent the seat belt
adjusting devices from operating to
remove slack, or prevent the seat
belt assembly from being adjusted to
remove slack.
WARNING
Damaged seat belts and seat belt
assemblies will not operate properly.
Always replace:
• Frayed, contaminated, or damaged
webbing
• Damaged hardware
• The entire seat belt assembly after it
has been worn in an accident, even
if damage to webbing or assembly is
not apparent

Seat Belt Restraint System
WARNING
Improperly positioned seat belts may
increase the risk of serious injury
in an accident. Take the following
precautions when adjusting the seat
belt:
• Position the lap portion of the seat
belt as low as possible across your
hips, not on your waist, so that it fits
snugly.
• Position one arm under the shoulder
belt and the other over the belt, as
shown in the illustration.
• Always position the shoulder belt
anchor into the locked position at the
appropriate height.
• NEVER position the shoulder belt
across your neck or face.
Seat Belt-Driver’s 3-point system
with emergency locking retractor
OHI038140
To fasten your seat belt:
Pull the seat belt out of the retractor and
insert the metal tab (1) into the buckle
(2). There will be an audible “click” when
the tab locks into the buckle.
OHI038137
You should place the lap belt (1) portion
across your hips and the shoulder belt (2)
portion across your chest.
The seat belt automatically adjusts to the
proper length after the lap belt portion
is adjusted manually so that it fits snugly
around your hips. If you lean forward in
a slow, easy motion, the belt will extend
and move with you.
If there is a sudden stop or impact, the
belt will lock into position. It will also lock
if you try to lean forward too quickly.

3-22
NOTICE
If you are not able to smoothly pull
enough of the seat belt out from the
retractor, firmly pull the seat belt out
and release it. After release, you will be
able to pull the belt out smoothly.
Height adjustment
You can adjust the height of the shoulder
belt anchor to one of the three different
positions for maximum comfort and
safety. The shoulder portion should be
adjusted so it lies across your chest and
midway over your shoulder nearest the
door, not over your neck. To adjust the
height of the seat belt anchor, lower
or raise the height adjuster into an
appropriate position.
„„Front seat
ODN8039072L
To raise the height adjuster, pull it up
(1). To lower it, push it down (3) while
pressing the height adjuster button (2).

into position. Try sliding the height
adjuster to make sure that it has locked
into position.
OHI038142
To release your seat belt:
Press the release button (1) in the locking
buckle.
When it is released, the belt should
automatically draw back into the
retractor. If this does not happen, check
the belt to be sure it is not twisted, then
try again.
Rear Seat Belt – Passenger’s 3-point
system with convertible locking
retractor
This type of seat belt combines the
features of both an emergency locking
retractor seat belt and an automatic
locking retractor seat belt. Convertible
retractor type seat belts are installed
in the rear seat positions to help
accommodate the installation of child
restraint systems. Although a convertible
retractor is also installed in the front
passenger seat position, NEVER place
any infant/child restraint system in the
front seat of the vehicle.
