(Continued)
5. Remove the filter cover by disengaging the
retaining tab and mid way snap that secures
the filter cover to the HVAC housing. Disengage
the mid way snap by pulling the door outward.
Unhinge the filter cover on the right side to fully
remove the cover.

Cabin Air Filter Cover

6. Remove the cabin air filter by pulling it straight out of the housing.
7. Install the cabin air filter with the arrow on the filter pointing toward the floor. When installing
the filter cover, make sure the retaining tabs
fully engage the cover. 8. Reinstall the glove compartment door on the
door hinge and reattach the tension tether by
inserting the tether clip in the glove
compartment and sliding the clip away from
the face of the glove compartment door.
9. Push the door to the near closed position to reengage the glove compartment travel stops.
NOTE:Ensure the glove compartment door hinges and
glove compartment travel stops are fully engaged.
ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal. This is
not a reason to replace belt. However, cracks
running along a rib (not across) are not normal. Any
belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has
excessive wear, frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

1 — Retaining Tab
2 — Mid Way Snap
3 — Filter Cover Hinge
CAUTION!
The cabin air filter is identified with an arrow to
indicate airflow direction through the filter.
Failure to properly install the filter will result in
the need to replace it more often.
WARNING!
Do not attempt to inspect an accessory drive
belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could be
injured by the moving fan blades.
You can be badly injured working on or around
a motor vehicle. Only do service work for which
you have the knowledge and the proper equip
-
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.
WARNING!

268SERVICING AND MAINTENANCE
(Continued)
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Ú page 250.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the Brake System Warning Light is
on. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
With disc brakes, fluid level can be expected to fall
as the brake pads wear. Brake fluid level should be
checked when pads are replaced. If the brake fluid
is abnormally low, check the system for leaks. For
further information Ú page 307.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only the manufacturer’s recommended
brake fluid Úpage 307. Using the wrong type
of brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
