Seats and Restraints 47
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may provide
added seat belt comfort for older children
who have outgrown booster seats and for
some adults. When installed on a shoulder
belt, the comfort guide positions the
shoulder belt away from the neck and head.
The comfort guides for the second row
outboard seating positions of this vehicle are
provided in a package in the glovebox or
cargo area. Instructions are included with
the guides.
Additional comfort guides are available
through your dealer for the rear seating
positions. Instructions are included with the
guides.
Seat Belt Use During Pregnancy
Seat belts work for everyone, including
pregnant women. Like all occupants, they
are more likely to be seriously injured if
they do not wear seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion should
be worn as low as possible, below the
rounding, throughout the pregnancy.
The best way to protect the fetus is to
protect the mother. When a seat belt is
worn properly, it is more likely that the
fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to
making seat belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten around
you, you should use it.But if a seat belt is not long enough, your
dealer will order you an extender. When
you go in to order it, take the heaviest coat
you will wear, so the extender will be long
enough for you. To help avoid personal
injury, do not let someone else use it, and
use it only for the seat it is made to fit. The
extender has been designed for adults.
Never use it for securing child restraints. For
more information on the proper use and fit
of seat belt extenders see the instruction
sheet that comes with the extender.
Safety System Check
Periodically check the seat belt reminder,
seat belts, buckles, latch plates, retractors,
shoulder belt height adjusters (if equipped),
and seat belt anchorages to make sure they
are all in working order. Look for any other
loose or damaged seat belt system parts
that might keep a seat belt system from
performing properly. See your dealer to
have it repaired. Torn, frayed, or twisted
seat belts may not protect you in a crash.
Torn or frayed seat belts can rip apart under
impact forces. If a belt is torn or frayed,
have it replaced immediately. If a belt is
twisted, it may be possible to untwist by

184 Climate Controls
Air Vents
Move the slider knobs to change the
direction of the airflow and to shut off the
air flow.
Use the thumbwheel near the air vents to
control the amount of airflow or to shut off
the airflow.
Operation Tips
.Clear away any ice, snow, or leaves from
the air inlets at the base of the
windshield that can block the flow of air
into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Keep all outlets open whenever possible
for best system performance.
.Keep the path under all seats clear of
objects to help circulate the air inside the
vehicle more effectively.
.Use of non-GM approved hood deflectors
can adversely affect the performance of
the system.
Maintenance
Passenger Compartment Air Filter
The filter removes dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle.
The filter should be replaced as part of
routine scheduled maintenance. To find out
what type of filter to use, seeMaintenance
Replacement Parts 0323.

2. Squeeze both sides of the glove box bininward to lower beyond the stops.
3. Release the latches on either side of theservice door. Open the service door and
remove the old filter.
4. Install the new air filter. Ensure air filter orientation is correct.
5. Close the service door completely.
6. Reverse the steps to reinstall the glove box.
See your dealer if additional assistance is
needed.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See your dealer for service.
