300 Vehicle Care
There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrake/clutchhydraulic system. Have thebrake/clutch hydraulic systemfixed. With a leak, the brakes willnot work well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake/clutch fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake/clutch hydraulicsystem.
{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/clutch
hydraulic system.
When the brake/clutch fluid falls to alow level, the brake warning lightcomes on. SeeBrake SystemWarning Light0120.
Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluidat the specified intervals to preventincreased stopping distance. SeeMaintenance Schedule0366.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0375.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
For diesel engine vehicles, see“Battery”in the Duramax dieselsupplement.
The original equipment battery ismaintenance free. Do not removethe cap and do not add fluid.

What to Use
Refer toRecommended Fluids andLubricants0375to determine whatkind of lubricant to use.
Rear Axle
When to Check and ChangeLubricant
It is not necessary to regularlycheck rear axle fluid unless a leak issuspected, or an unusual noise isheard. A fluid loss could indicate aproblem. Have it inspected andrepaired.
All axle assemblies are filled byvolume of fluid during production.They are not filled to reach a certainlevel. When checking the fluid levelon any axle, variations in thereadings can be caused by factoryfill differences between the minimumand the maximum fluid volume.Also, if a vehicle has just beendriven before checking the fluidlevel, it may appear lower thannormal because fluid has traveledout along the axle tubes and hasnot drained back to the sump area.Therefore, a reading taken
five minutes after the vehicle hasbeen driven will appear to have alower fluid level than a vehicle thathas been stationary for an hour ortwo. The rear axle assembly mustbe supported on a flat, level surfaceto get a true reading.
How to Check Lubricant
Rear Axle for 2.5L Shown, Rear
Axle for 3.6L Similar
1. Drain Plug
2. Fill Plug
To g e t a n a c c u r a t e r e a d i n g , t h evehicle should be on a levelsurface.
If the level is below the bottom ofthe fill plug (2) hole, located on therear axle, some lubricant will needto be added. Add enough lubricantto raise the level to the bottom ofthe fill plug (2) hole. Use care not toovertighten the plug.

Parking for an extended period cancause flat spots on the tires thatmay result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tires orraise the vehicle to reduce theweight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
vehicle, including brake system
performance, ride and handling,
traction control, and tire
pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow. SeeTire Sidewall
Labeling0318for additional
information.
GM recommends replacing worn
tires in complete sets of four.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
If proper rotation and
maintenance have been done,
all four tires should wear out at
about the same time. SeeTire
Rotation0329for information
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle.
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{Warning
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.

332 Vehicle Care
Warning (Continued)
This vehicle may have a
different size spare than the
road tires originally installed
on the vehicle. When new, the
vehicle included a spare tire
and wheel assembly with a
similar overall diameter as the
road tires and wheels, so it is
all right to drive on it. The
spare tire was developed for
use on this vehicle and will not
affect vehicle handling.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, Y a n d Z R s p e e d r a t e d
tires. Never exceed the winter
tires’maximum speed capability
when using winter tires with a
lower speed rating.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
SeeTire Pressure Monitor
System0325.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0226for the label location and
more information about the Tire
and Loading Information label.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, electronic stability control,or All-Wheel Drive, the performanceof these systems can also beaffected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
