Caution (Continued)
.Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if it
is completely full.
Brakes
Disc brake linings have built-in
wear indicators that make a
high-pitched warning sound
when the brake linings are
worn and new linings are
needed. The sound can come
and go or can be heard all the
time when the vehicle is
moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning
sound means that soon the
brakes will not work well.
That could lead to a crash.(Continued)
Warning (Continued)
When the brake wear
warning sound is heard,
have the vehicle serviced.
Caution
Continuing to drive with
worn-out brake linings could
result in costly brake repairs.
Some driving conditions or
climates can cause a brake
squeal when the brakes are
first applied, clearing up
following several applications.
This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts
are necessary to help prevent
brake pulsation. When tires
are rotated, inspect brake
linings for wear and evenly
tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities
and Specifications 0463. Brake pads should be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake
pedal does not return to
normal height, or if there is a
rapid increase in pedal travel.
This could be a sign that brake
service may be required.
Replacing Brake System
Parts
Always replace brake system
parts with new, approved
replacement parts. If this is
not done, the brakes may not
work properly. The braking
performance can change in
many ways if the wrong brake
parts are installed or if parts
are improperly installed.

Vehicle Care 445
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper electrical connections,
binding, cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
door hinges, hood hinges,
liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic.
Applying silicone grease on
weatherstrips with a clean
cloth will make them last
longer, seal better, and not
stick or squeak.
Underbody Maintenance
At least twice a year, spring
and fall, use plain water to
flush any corrosive materials
from the underbody. Take care
to thoroughly clean any areas
where mud and other debris
can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.
