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 Ú page 255.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú page 316.
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 manufacturer's recommended brake
fluid Úpage 316. 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 a 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.

Replacing Exterior Bulbs
LOW BEAM HEADLAMP, HIGH BEAM
HEADLAMP — MODELS WITH HALOGEN
HEADLAMPS — IF EQUIPPED
See below steps to replace:

1. Open the hood.

Headlamp Assembly Dust Cap Location

NOTE:Removal of the air cleaner filter housing may be
necessary prior to replacing bulbs in the headlamp
assembly on the driver side of the vehicle.
2. Remove the large dust cap from the headlamp housing by turning it counterclockwise.
3. Turn the bulb counterclockwise, and remove.
Headlamp Location

4. Disconnect the bulb from the socket assembly and install the replacement bulb.
5. Reinstall the bulb and socket assembly into the headlamp assembly, and then turn it
clockwise. 6. Reinstall the access cap making sure it is
seated into the housing and turn cap
clockwise to engage locking lugs. Visually, you
should be unable to see the blue O-ring gasket.
The access cap should be uniformly seated
and you should not be able to pull the access
cap off without turning it counterclockwise.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
CAUTION!
If the access cap is not installed correctly after
bulb replacement, the lamp becomes
susceptible to dust, condensation, and water
intrusion. This may ultimately lead to an
inoperative lamp. If the access cap cannot be
installed correctly, please return to an
authorized dealer for proper repair or access
cap replacement if necessary.
