To disconnect the jumper cables from both vehicles, do
the following:1. Disconnect the black negative (−) cable from the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the vehicle with the good battery.
4. Disconnect the red positive (+) cable from the other vehicle.
5. Return the remote positive (+) terminal cover to its original position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may be
necessary.
If oncoming vehicles flash their high beams at you, this
may also mean the vertical aim needs to be adjusted. It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be re-aimed.
It is possible however, to re-aim the headlamps as
described.
Notice:
To make sure the headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should:
.Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
.Have all four tires on a level surface which is level
all the way to the wall.
.Be placed so it is perpendicular to the wall.
.Not have any snow, ice, or mud on it.
.Be fully assembled and all other work stopped
while headlamp aiming is being performed.
.Be normally loaded with a full tank of fuel and
one person or 160 lbs (75 kg) sitting on the
driver seat.
.Have all tires properly inflated.
.Have the spare tire is in its original location in the
vehicle.

A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. SeeLoading the
Vehicle
on page 5‑18, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also see Inflation - Tire Pressure on page 6‑57.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation
on
page 6‑65and Tires on page 6‑48.
Notice: Tire sealant materials are not all the same.
A non-approved tire sealant could damage the Tire
Pressure Monitor System (TPMS) sensors. TPMS
sensor damage caused by using an incorrect tire
sealant is not covered by the vehicle warranty.
Always use only the GM approved tire sealant
available through your dealer or included in the
vehicle.
Factory-installed Tire Inflator Kits use a GM approved
liquid tire sealant. Using non-approved tire sealants
could damage the TPMS sensors. See Tire Sealant and
Compressor Kit
on page 6‑75for information regarding
the inflator kit materials and instructions.
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until
the problem is corrected. Some of the conditions that
can cause the malfunction light and DIC message to
come on are:
.One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re‐install the road
tire containing the TPMS sensor.
.The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle's tires. The DIC message
and TPMS malfunction light should go off once the
TPMS sensor matching process is performed
successfully. See “TPMS Sensor Matching
Process” later in this section.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. SeeWhen It Is Time for New
Tires
on page 6‑67for more information.
Always remove the tires if any of the following
statements are true:
.You can see the indicators at three or more
places around the tire.
.You can see cord or fabric showing through
the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show cord or
fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Tires should be rotated every 12 000 km
(7,500 miles). See Scheduled Maintenance
on
page 7‑3
. The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform
most like it did when the tires were new.
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 6‑67
and Wheel Replacementon page 6‑72
for more information.
Four‐Tire Rotation Pattern
If your vehicle has a compact spare tire, it should
not be included in the tire rotation process. Use
the four‐tire rotation pattern shown.

WARNING: (Continued)
Your vehicle may have a compact spare tire and
wheel assembly. If the vehicle has a compact
spare tire and wheel, they have the same overall
diameter as your vehicle's full‐size tires and
wheels. Because they were designed and
developed for use on your vehicle, it is all right to
drive your vehicle with the compact spare installed
properly. Compact spare tires are designed for
temporary use only. SeeSpare Tire
on
page 6‑93
.
{WARNING:
If you use bias-ply tires on the vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use
only radial-ply tires with the wheels on the
vehicle.
If you must replace your vehicle's tires with those
that do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias‐belted tires) as your
vehicle's 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 on your vehicle.
Non‐TPC Spec rated tires may give a low‐pressure
warning that is higher or lower than the proper warning
level you would get with TPC Spec rated tires. See Tire
Pressure Monitor System on page 6‑60.
Your vehicle's original equipment tires are listed on the
Tire and Loading Information Label. See Loading the
Vehicle
on page 5‑18, for more information about the
Tire and Loading Information Label and its location on
your vehicle.

Tire Sealant and Compressor Kit
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen or
smelled. It can cause unconsciousness and even
death. Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑33.
{WARNING:
Over-inflating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor
kit instructions and inflate the tire to its
recommended pressure. Do not exceed the
recommended pressure.
{WARNING:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to store
a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to 6 mm (¼ inch) in the
tread area of the tire. It can also be used to inflate an
under inflated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire is
too severely damaged for the tire sealant and
compressor kit to be effective. See Roadside Service
on page 8‑7.
