Put an automatic transmission in PARK (P) 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 your radio or other
accessories on during the jump starting
procedure, they could be damaged.
The repairs would not be covered by
your warranty. Always turn off your radio
and other accessories when jump
starting your 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!
4. Open the hoods and locate the positive (+)
and negative (−) terminal locations on the
other vehicle. Your vehicle has a remote
positive (+) and a remote negative (−) jump
starting terminal. SeeEngine Compartment
Overview on page 324for more information on
the terminal locations.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need more
light.
Be sure the batteries have enough water.
You do not need to add water to the
ACDelco
®battery (or batteries) installed in
your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is
there. If it is low, add water to take care of
that rst. If you do not, explosive gas
could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.

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.

Tire Size
The following illustration shows an example of a
typical passenger vehicle tire size.
(A) 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 70, as
shown in item C of the illustration, it would mean
that the tire’s sidewall is 70 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 certi ed to carry. The load index
can range from 1 to 279. The speed rating is
the maximum speed a tire is certi ed to carry a
load. Speed ratings range from A to Z.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly in ated simply by looking at them. Radial
tires may look properly in ated even when they
are underin ated. Check the tire’s in ation
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
in ation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
in ation pressure is low, add air until you reach the
recommended amount.
If you over ll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Recheck the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor System
(TPMS). This system uses radio and sensor
technology to check tire pressure levels. TPMS
sensors are mounted onto each tire and wheel
assembly on your vehicle, except the spare tire.
The TPMS sensors monitor the air pressure
in your vehicle’s tires and transmit the tire pressure
readings to a receiver located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning light located in the instrument panel
cluster, and at the same time display the LOW
TIRE warning message on the Driver Information
Center (DIC). The low tire pressure warning
light and the LOW TIRE warning message appear
at each ignition cycle until the tires are in ated
to the correct in ation pressure.

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 in ation
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
In ation - 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.

TPMS Sensor Identi cation Codes
Each TPMS sensor has a unique identi cation
code. Any time you replace one or more of
the TPMS sensors or rotate your vehicle’s tires,
the identi cation 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’s side front tire, passenger’s side
front tire, passenger’s side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors may 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 in ation
pressure indicated on the tire’s sidewall.
You will have one minute to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions.If it takes longer than one minute, 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 will need to
start over.
The TPMS sensor matching procedure is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Turn the exterior lamp switch from AUTO to
OFF four times within three seconds. A
double horn chirp will sound and the TPMS
low tire warning light starts ashing. The
double horn chirp and ashing TPMS warning
light indicates the TPMS matching process
has started. The TPMS warning
light should continue ashing throughout
the matching procedure. The LOW TIRE
message displays on the Driver Information
Center (DIC).
4. Start with the driver’s side front tire.
381

5. Remove the valve cap from the valve cap
stem. Activate the TPMS sensor by
increasing or decreasing the tire’s air pressure
for 10 seconds, then stop and listen for a
single horn chirp. The single horn chirp should
sound within 15 seconds, con rming that
the sensor identi cation code has been
matched to this tire and wheel position. If you
do not hear the con rming single horn
chirp, turn the ignition switch to LOCK and
start over beginning with Step 2. To let
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.
6. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 5.8. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 5.
9. After hearing the con rming horn chirp for the
driver side rear tire, check to see if the TPMS
low tire warning light and the DIC LOW
TIRE messages have turned off. If yes, the
TPMS sensors have been relearned. Turn the
ignition switch to LOCK.
If the low tire warning light and the DIC SERV
TPM messages are on after completing
Step 5 for the driver side rear tire, the sensor
relearn process has not been successful.
Turn the ignition switch to LOCK and repeat
the matching process beginning with Step 2.
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
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.
