At the same time a message to
check the pressure in a specific 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
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by
the driver. For additional information
and details about the DIC operation
and displays seeDriver Information
Center (DIC)
on page 5‑25and
Tire Messages on page 5‑37.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first 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 inflated 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 inflation pressure for your
vehicle's tires when they are cold.
See
Vehicle Load Limits
on
page 9‑12, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure
on
page 10‑44.
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑50,Tire Rotationon
page 10‑50and Tires on
page 10‑37. Notice:
Using non-approved tire
sealants 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 the
GM approved tire sealant
available through your dealer/
retailer.
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 10‑60for
information regarding the inflator kit
materials and instructions.

10-50 Vehicle Care
Tire Inspection
We recommend that you
regularly inspect your 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 10‑51
for more information.
Tire Rotation
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). See Scheduled
Maintenance
on page 11‑2.
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.
See
When It Is Time for New
Tires
on page 10‑51and Wheel
Replacement
on page 10‑56.
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
inflation pressures as shown on
the Tire and Loading Information
label. See
Tire Pressure
on
page 10‑44
and Vehicle Load
Limits
on page 9‑12.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation
on page 10‑46.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and Specifications
on
page 12‑2
.

Vehicle Care 10-51
{WARNING
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
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, 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. SeeIf a Tire Goes Flat
on page 10‑58.
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
Tire Changing
on page 10‑68.
When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1.6 mm (1/16 inch) or
less of tread remaining. The vehicle needs 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. This is also true for the spare
tire, if the vehicle has one, even
if it is not being used. Multiple
conditions affect how fast this
aging takes place, including
temperatures, loading conditions,
and inflation pressure maintenance.

10-52 Vehicle Care
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
specific 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
Specification (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 specifications 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. See
Tire
Sidewall Labeling
on page 10‑38
for 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. Replacing
less than a full set of tires can
affect the braking and handling
performance of your vehicle.
See Tire Inspection
on page 10‑50
andTire Rotationon page 10‑50
for information on proper tire
rotation.

10-58 Vehicle Care
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 flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. 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.{WARNING
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 flat 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 flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑4.

10-92 Vehicle Care
Finish Damage
Any stone chips, fractures or deep
scratches in the finish 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 finish 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, floor pan,
and exhaust system even though
they have corrosion protection.At least every spring, flush 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
flushed. 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.
Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Dust and dirt can accumulate on the
upholstery and cause damage to
the carpet, fabric, leather, and
plastic surfaces. Stains should be
removed quickly as extreme heat
could cause them to set rapidly.
Lighter colored interiors may require
more frequent cleaning.
Newspapers and garments that can
transfer color to home furnishings
can also transfer color to the
vehicle's interior.
Remove dust from small buttons
and knobs with a small brush with
soft bristles.
