Make sure that the coolant expansion bottle over-
flow 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 necessary, install
ONLY the correct type thermostat. Other designs
may result in unsatisfactory engine cooling perfor-
mance, poor gas mileage, and increased emissions.
The coolant freeze point in the battery and power
electronics loop should be checked by an authorized
dealer as a special tool is required to remove the
cap from those expansion bottles.
Electric/Battery coolant system must be serviced by
an authorized dealer. If the coolant level is below
what is specified on the reservoir, contact an autho-
rized dealer for service. These systems require the
use of high purity water such as deionized, or distilled
water when mixing the water and coolant solution.
The use of lower quality water will reduce the amount
of corrosion protection in the cooling systems.

BRAKE SYSTEM

In order to ensure brake system performance, all brake
system components should be inspected periodically.
For the proper maintenance intervals
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high
brake temperatures, excessive lining wear, and pos-
sible brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or immediately if
the Brake Warning Light is illuminated.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid 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. Brake fluid
level should be checked when pads are replaced. How-
ever, low fluid level may be caused by a leak and a
checkup may be needed.
Use only manufacturer recommended brake fluid
page 314.
Use only manufacturer recommended brake fluid
page 314. 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 origi-
nal 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 pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
WARNING!

SERVICING AND MAINTENANCE
WARNING!
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 contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake fail-
ure. This could result in a collision.

AUTOMATIC TRANSMISSION

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product and
its performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to the
transmission. Avoid using transmission sealers as they
may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
