exercise care when using the seat heater. The seat heater may cause
burns even at low temperatures, especially if used for long periods of
time. Do not place anything on the seat that insulates against heat,
such as a blanket or cushion, because this may cause the seat heater
to overheat. Do not puncture the seat with pins, needles, or other
pointed objects because this may damage the heating element which
may cause the seat heater to overheat. An overheated seat may cause
serious personal injury.
Note:Do not do the following:
•Place heavy objects on the seat.
•Operate the seat heater if water or any other liquid is spilled on the
seat. Allow the seat to dry thoroughly.
To operate the heated seats, do the following (engine must be running):

securely fastened in the buckle.
2. To unfasten, push the release
button and remove the tongue from
the buckle.
Vehicle sensitive mode
Combination lap and shoulder belts in normal retractor mode allow free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of
approximately 5 mph (8 km/h) or more, the combination safety belts will
lock to help reduce forward movement of the driver and passengers.
Belt sensitive mode
Combination lap and shoulder belts can also be made to lock manually by
quickly pulling on the shoulder belt.
Automatic locking mode
When to use the automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.

How to use the automatic locking mode
•Buckle the combination lap and
shoulder belt.
•Grasp the shoulder portion and
pull downward until the entire

completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the front passenger and rear outboard
seat belt systems must be checked by your authorized dealer to
verify that the “automatic locking retractor” feature for child seats is
still functioning properly. In addition, all seat belts should be checked
for proper function.

BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly “automatic locking retractor” feature or
any other seat belt function is not operating properly when checked
according to the procedures in theWorkshop Manual. Failure to
replace the belt and retractor assembly could increase the risk of
injury in collisions.
Energy management feature
•This vehicle has a seat belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
•The front outboard seat belt systems have a retractor assembly that is
designed to pay out webbing in a controlled manner. This feature is
designed to help reduce the belt force acting on the occupant’s chest.
Safety belt pretensioner
Your vehicle is equipped with safety belt retractor pretensioners at the
driver and front outboard passenger seating positions.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts during
some collisions in such a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to theSafety belt maintenancesection in this
chapter.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Front safety belt height adjustment
The front outboard seating positions are equipped with safety belt height
adjusters.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder.
