268 VEHICLE CARE
Brake pads should be replaced as
complete 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 expected can change in
many other ways if the wrong
replacement brake parts are installed
or if parts are improperly installed.
Brake Fluid
The brake master cylinder reservoir is
filled with GM approved DOT 3 brake
fluid as indicated on the reservoir cap.
SeeEngine Compartment Overview
0 256 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum
marks on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
. Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.
. A fluid leak in the brake hydraulic
system. Have the brake hydraulic
system fixed. With a leak, the
brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it.
Do not top off the brake fluid. Adding
fluid does not correct a leak. If fluid is
added when the linings are worn,
there will be too much fluid when new brake linings are installed. Add or
remove fluid, as necessary, only when
work is done on the brake hydraulic
system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake hydraulic system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning Light
0 135.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0326.

296 VEHICLE CARE
Use this rotation pattern when
rotating the tires.
Do not include the compact spare
tire in the tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and Loading
Information label after the tires
have been rotated. SeeTire
Pressure 0288 and Vehicle Load
Limits 0180.
Reset the Tire Pressure Monitor
System. See Tire Pressure Monitor
Operation 0291. Check that all wheel nuts are
properly tightened. See
“Wheel
Nut Torque ”under Capacities and
Specifications 0338.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause a crash. When
changing a wheel, remove any rust
or dirt from places where the wheel
attaches to the vehicle. In an
emergency, a cloth or a paper towel
can be used; however, use a scraper
or wire brush later to remove all
rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or
rust build-up. Do not get grease
on the flat wheel mounting
surface or on the wheel nuts or
bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds, vehicle
loading, and road conditions affect the
wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when the
tires have only 1.6 mm (1/16 in) or
less of tread remaining. See Tire
Inspection 0295 and Tire Rotation
0 295.

Transportation Options
Warranty service can generally be
completed while you wait. However,
if you are unable to do so, your dealer
may offer the following transportation
options:
Shuttle Service
This includes one-way or round-trip
shuttle service within reasonable time
and distance parameters of your
dealer's area.
Public Transportation or Fuel
Reimbursement
If overnight warranty repairs are
needed, and public transportation is
used, the expense must be supported
by original receipts and within the
maximum amount allowed by GM for
shuttle service. If U.S. customers
arrange their own transportation,
limited reimbursement for reasonable
fuel expenses may be available. Claim
amounts should reflect actual costs
and be supported by original receipts.
See your dealer for information.Courtesy Rental Vehicle
For an overnight warranty repair, the
dealer may provide an available
courtesy rental vehicle or provide for
reimbursement of a rental vehicle.
Reimbursement is limited and must
be supported by original receipts as
well as a signed and completed rental
agreement and meet state/provincial,
local, and rental vehicle provider
requirements. Requirements vary and
may include minimum age
requirements, insurance coverage,
credit card, etc. Additional fees such
as fuel usage charges, taxes, levies,

discretion.
Collision Damage Repair
If the vehicle is involved in a collision
and it is damaged, have the damage
repaired by a qualified technician
using the proper equipment and
quality replacement parts. Poorly
performed collision repairs diminish
the vehicle resale value, and safety
performance can be compromised in
subsequent collisions.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the parts
with which the vehicle was originally
built. Genuine GM Collision parts are
the best choice to ensure that the
vehicle's designed appearance,
durability, and safety are preserved.
The use of Genuine GM parts can help
maintain the GM New Vehicle Limited
Warranty.
