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 (With DIC Buttons) on
page 3-46orDIC Operation and
Displays (Without DIC Buttons) on
page 3-51andDIC Warnings and
Messages on page 3-56.The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.
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 the Vehicle
on page 4-16, for an example of
the Tire and Loading Information
label and its location on your
vehicle. Also seeInflation - Tire
Pressure on page 5-41.
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 5-47andTires
on page 5-35.

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 5-48
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.
SeeWhen It Is Time for
New Tires on page 5-48
andWheel Replacement
on page 5-53.When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.
If the vehicle has a compact
spare tire, do not include it in
the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 5-41andLoading the
Vehicle on page 4-16.
Service and Appearance Care 5-47

Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 5-44.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications
on page 5-96.
{CAUTION
Rust or dirt on a wheel, or
on the parts to which it is
fastened, can make wheel
nuts become loose after time.
The wheel could come off and
cause an accident. When you
change a wheel, remove any
(Continued)
CAUTION (Continued)
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, you
can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if needed, to get all the
rust or dirt off. SeeChanging
a Flat Tire on page 5-69.
Make sure the spare tire, if
the vehicle has one, is stored
securely. Push, pull, and then
try to rotate or turn the tire. If it
moves, tighten the cable. See
Storing a Flat or Spare Tire and
Tools on page 5-78.When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions inuence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which will appear
when the tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
5-48 Service and Appearance Care

You need new 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.
The rubber in tires degrades over
time, even if they are not being
used. This is also true for the spare
tire, if the vehicle has one. Multiple
conditions affect how fast this
aging takes place, including
temperatures, loading conditions,
and ination pressure maintenance.With proper care and maintenance
tires typically wear out before
they degrade due to age. If you are
unsure about the need to replace
the tires as they get older, consult
the tire manufacturer for more
information.
Buying New Tires
GM has developed and matched
specic tires for your vehicle. The
original equipment tires installed
on your vehicle, when it was new,
were designed to meet General
Motors Tire Performance Criteria
Specication (TPC Spec) system
rating. If you need replacement
tires, GM strongly recommends
that you get tires with the same
TPC Spec rating. This way, your
vehicle will continue to have tires
that are designed to give the
same performance and vehicle
safety, during normal use, as the
original tires.GM’s exclusive TPC Spec
system considers over a dozen
critical specications that impact
the overall performance of your
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 an MS for mud and snow.
SeeTire Sidewall Labeling
on page 5-36for additional
information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires
will help keep your vehicle
performing most like it did
when the tires were new.

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially
if you maintain the tires properly.
SeeTires on page 5-35.Ifair
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 youwould 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.
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning
ashers. SeeHazard Warning
Flashers on page 3-5.
2. Park the vehicle. Set the parking
brake rmly and put the shift
lever in P (Park).
3. Turn off the engine.
4. Inspect the at tire.{CAUTION
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
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. If a jack is provided
with the vehicle, only use it for
changing a at tire.
This vehicle may come with a jack
and spare tire or a tire sealant
and compressor kit. To use the jack
and spare tire, seeChanging a
Flat Tire on page 5-69. To use the
tire sealant and compressor kit,
seeTire Sealant and Compressor
Kit on page 5-56.
Service and Appearance Care 5-55

Finish Damage
Any stone chips, fractures or deep
scratches in the nish should be
repaired right away. Bare metal will
corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of nish damage
can be corrected in your dealer’s/
retailer’s body and paint shop.
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/retailer
or an underbody car washing
system can do this.
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, we 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.
Vehicle Identication
Vehicle Identication
Number (VIN)
This is the legal identier for your
vehicle. It appears on a plate in the
front corner of the instrument panel,
on the driver side. It can be seen
through the windshield from outside
the vehicle. The VIN also appears on
the Vehicle Certication and Service
Parts labels and the certicates of
title and registration.
Engine Identication
The eighth character in the VIN is the
engine code. This code helps identify
the vehicle’s engine, specications,
and replacement parts. See “Engine
Specications” underCapacities and
Specifications on page 5-96for your
vehicle’s engine code.

Scheduled Maintenance
When the CHANGE ENGINE OIL
SOON message displays, service is
required for the vehicle. Have the
vehicle serviced as soon as possible
within the next 600 miles (1 000 km).
It is possible that, if driving under the
best conditions, the engine oil life
system might not indicate that
vehicle service is necessary for over
a year. However, the engine oil and
lter must be changed at least once
a year and at this time the system
must be reset. Your dealer/retailer
has trained service technicians who
will perform this work using genuine
parts and reset the system.
Maintenance Schedule 6-3

If the engine oil life system is ever
reset accidentally, service the vehicle
within 3,000 miles (5 000 km) since
the last service. Remember to reset
the oil life system whenever the oil
is changed. SeeEngine Oil Life
System on page 5-13for information
on the Engine Oil Life System and
resetting the system.
When the CHANGE ENGINE OIL
SOON message appears, certain
