Brake Wear
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake
pads are worn and new pads are
needed. The sound can come
and go or be heard all the time the
vehicle is moving, except when
applying the brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
an accident. When the brake wear
warning sound is heard, have the
vehicle serviced.Notice:Continuing to drive with
worn-out brake pads could
result in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or lightly
applied. 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 pads for wear
and evenly tighten wheel nuts in
the proper sequence to torque
specications inCapacities and
Specifications on page 5-98.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer/retailer 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 might
be required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle
moving, the brakes adjust for wear.
5-26 Service and Appearance Care

Jump Starting
If the vehicle’s battery has run
down, you may want to use another
vehicle and some jumper cables
to start your vehicle. Be sure to use
the following steps to do it safely.
{CAUTION
Batteries can hurt you. They can
be dangerous because:
They contain acid that can
burn you.
They contain gas that can
explode or ignite.
They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.Notice:Ignoring these steps
could result in costly damage to
your vehicle that would not
be covered by your warranty.
Trying to start your vehicle
by pushing or pulling it will not
work, and it could damage
your vehicle.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice:If the other vehicle’s
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Get the vehicles close enough so
the jumper cables can reach, but
be sure the vehicles are not
touching each other. If they are, it
could cause a ground connection
you do not want. You would not
be able to start your vehicle, and
the bad grounding could damage
the electrical systems.To avoid the possibility of the
vehicles rolling, set the parking
brake rmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer case
is not in Neutral.
Notice:If you leave the radio or
other accessories on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off
the radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not needed.
This will avoid sparks and help
save both batteries. And it could
save the radio!
5-28 Service and Appearance Care

All-Wheel Drive
Be sure to perform the lubricant
checks described in this section.
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. SeeScheduled
Maintenance on page 6-3.How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level surface.
If the level is below the bottom of
the ller plug hole, you will need to
add some lubricant. 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 6-12.

letters and numbers dene a
tire’s width, height, aspect ratio,
construction type, and service
description. The letter T as
the rst character in the tire size
means the tire is for temporary
use only.
(G) TPC Spec (Tire
Performance Criteria
Specication)
:Original
equipment tires designed to
GM’s specic tire performance
criteria have a TPC specication
code molded onto the sidewall.
GM’s TPC specications meet or
exceed all federal safety
guidelines.Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States version of a
metric tire sizing system. The
letter P as the rst character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(B) Tire Width
:The three-digit
number indicates the tire
section width in millimeters from
sidewall to sidewall.
(C) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply construction;
and the letter B means
belted-bias ply construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These
characters represent the load
range and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certied to carry. The load index
can range from 1 to 279. The
speed rating is the maximum
speed a tire is certied to carry
a load. Speed ratings range
fromAtoZ.

Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s
tires and transmit tire pressure
readings to a receiver located in
the vehicle.
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 tirepressure 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.
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.
SeeTire Pressure Monitor
Operation on page 5-45for
additional information.

The TPMS operates on a radio
frequency and complies with
RSS-210 of Industry and Science
Canada. Operation is subject to
the following two conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.Changes or modications to this
system by other than an authorized
service facility could void
authorization to use this equipment.
Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn
the driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire
and wheel assembly, excluding the
spare tire and wheel assembly,
if the vehicle has one. The TPMS
sensors monitor the air pressure in
the vehicle’s tires and transmits
the tire pressure readings to
a receiver located in the vehicle.When a low tire pressure condition is
detected, the TPMS illuminates the
low tire pressure warning light
located on the instrument panel
cluster.
At the same time a message to
check the pressure in a specic tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. Using the DIC, tire
pressure levels can be viewed by the
driver. For additional information and
details about the DIC operation and
displays seeDIC Operation and
Displays on page 3-41andDIC
Warnings and Messages on
page 3-48.
Service and Appearance Care 5-45

One or more TPMS sensors
are missing or damaged.
The DIC message and the
TPMS malfunction light should
go off when the TPMS sensors
are installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
Replacement tires or wheels do
not match your vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. SeeBuying
New Tires on page 5-50.
Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer/ retailerfor service if the TPMS malfunction
light and DIC message comes
on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time you
rotate your vehicle’s tires or replace
one or more of the TPMS sensors,
the identication codes will need to
be matched to the new tire/wheel
position. The sensors are matched to
the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear tire
using a TPMS diagnostic tool. See
your dealer/ retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall.To decrease air-pressure out of a
tire you can use the pointed
end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match
the rst tire/wheel position, and
ve minutes overall to match all
four tire/wheel positions. If it takes
longer than two minutes, to match
the rst tire and wheel, or more than
ve minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
Service and Appearance Care 5-47

3. Press the Remote Keyless
Entry (RKE) transmitter’s LOCK
and UNLOCK buttons at the
same time for approximately
ve seconds. The horn sounds
twice to signal the receiver
is in relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side
front tire.
5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for ve seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, conrms that the sensor
identication code has been
matched to this tire and wheel
position.
6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure in
Step 5. The horn sounds two
times to indicate the sensor
identication code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to
LOCK/OFF.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, if
the vehicle has one, for signs of
wear or damage. SeeWhen It Is
Time for New Tires on page 5-50
for more information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
