Replacing Brake System Parts
The braking system on a vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good
braking. Your vehicle was designed and tested
with top-quality GM brake parts. When you replace
parts of the braking system — for example,
when the brake linings wear down and you need
new ones put in — be sure you get new
approved GM replacement parts. If you do not, the
brakes may no longer work properly. For
example, if someone puts in brake linings
that are wrong for your vehicle, the balance
between the front and rear brakes can
change — for the worse. The braking performance
you have come to expect can change in many
other ways if someone puts in the wrong
replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 324for battery location.Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep
your battery from running down.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 354for tips on working
around a battery without getting hurt.

Rear Axle
When to Check and Change Lubricant
It is not necessary to regularly check rear axle
uid unless you suspect there is a leak or you hear
an unusual noise. A uid loss could indicate a
problem. Have it inspected and repaired.
How to Check Lubricant
To get an accurate reading, the vehicle should be
on a level surface.The proper level is from 0 to 3/8 inch
(0 mm to 10 mm) below the bottom of the
ller plug hole, located on the rear axle.
What to Use
SeeRecommended Fluids and Lubricants on
page 447to determine which kind of lubricant
to use.
Four-Wheel Drive
Lubricant checks in this section apply to this
vehicle. There are two additional systems that
need lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. SeeAdditional
Required Services on page 440.
How to Check Lubricant
To get an accurate reading, the vehicle should be
on a level surface.

A. Drain Plug
B. Filler Plug
If the level is below the bottom of the ller plug
hole, located on the transfer case, you’ll need to
add some lubricant. Remove the plug and
add enough lubricant to raise the level to the
bottom of the ller plug hole. Use care not
to overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 447.
Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check your front
axle uid unless you suspect there is a leak or you
hear an unusual noise. A uid loss could indicate
a problem. Have it inspected and repaired.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
on page 437for more information.
Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts on page 449.
Allowing the wiper blade arm to touch the
windshield when no wiper blade is installed could
damage the windshield. Any damage that
occurs would not be covered by your warranty. Do
not allow the wiper blade arm to touch the
windshield.
1. To remove the old wiper blades, lift the wiper
arm until it locks into a vertical position.A. Blade Assembly

C. Locking TabD. Blade Pivot
E. Hook Slot
F. Arm Hook
2. Press down on the blade assembly pivot
locking tab. Pull down on the blade assembly to
release it from the wiper arm hook.
3. Remove the insert from the blade assembly.
The insert has two notches at one end that are
locked by bottom claws of the blade assembly.
At the notched end, pull the insert from the
blade assembly.

For additional information and details about the
DIC operation and displays seeDIC Controls and
Displays on page 194andDIC Warnings and
Messages on page 198.
You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
DIC LOW TIRE message may come on when the
vehicle is rst started, and then turn off as you
start to drive. This may be an early indicator that
the air pressure in the tire(s) is getting low
and needs to be inated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even
if under-ination has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
379

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will ash for approximately
one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they are cold.
SeeLoading Your Vehicle on page 286, for an
example of the Tire and Loading Information
label and its location on your vehicle. Also see
Ination - Tire Pressure on page 377for additional
information.
Your vehicle’s TPMS can warn you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 383,When It Is Time for
New Tires on page 385, andTires on page 369.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 385
andWheel Replacement on page 390for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench to tighten the cable.
SeeChanging a Flat Tire on page 394.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important, seeScheduled
Maintenance on page 437.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a at
tire. If it is used for anything else, you or
others could be badly injured or killed if the
vehicle slips off the jack. Use the jack
provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to use the
jacking equipment to change a at tire safely.

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have
corrosion protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close
areas of the frame should be loosened before being
ushed. Your dealer or an underbody car washing
system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the vehicle.
This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes
this, GM will repair, at no charge to the owner,
the surfaces of new vehicles damaged by this
fallout condition within 12 months or 12,000 miles
(20 000 km) of purchase, whichever occurs rst.
