Setting the Compass
The compass is self-calibrating, which eliminates the
need to manually set the compass.
However, under certain circumstances, such as during a
long distance cross-country trip, it will be necessary
to compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between earth's
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
in your vehicle could give you false readings.
In order to do this, you will have to set or calibrate the
compass to the variance zone in which you are located.

PRESSURE warning
message.
If the vehicle has ABS brakes, this warning message
will appear when the air pressure in one of the tires
is too low or too high. Check the vehicle's tire pressure
as soon as possible, and ®ll the affected tire to the
appropriate level. The correct tire in¯ation pressure
should be set to those shown on the tire-loading
information label on the vehicle. See
Loading Your
Vehicle on page 4-35for more information.When you reset the CHECK TIRE PRESSURE screen
by acknowledging it, you must also reset the TIRE
INFLATION MONITOR SYSTEM screen located under
the option menu in the DIC. See ªTire In¯ation Monitor
Systemº in the options section under

Tire Pressure Monitor System
This vehicle has the tire in¯ation monitor system, it can
alert you to a large change in the pressure of one
tire. The system ªlearnsº the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
See
DIC Warnings and Messages on page 3-65for
more information.
This symbol, along with the
CHECK TIRE PRESSURE
warning message will
appear in the Driver
Information Center (DIC)
if the pressure in one tire
becomes 12 psi (83 kPa)
lower than the other
three tires.
The tire in¯ation monitor system won't alert you if the
pressure in more than one tire is low, if the system is not
properly calibrated, or if the vehicle is moving faster
than 70 mph (110 km/h).The tire in¯ation monitor system detects differences in
tire rotation speeds that are caused by changes in tire
pressure. The system can alert you about a low tire ± but
it doesn't replace normal tire maintenance. See
Tires on
page 5-68.
When the CHECK TIRE PRESSURE warning message
comes on, you should stop as soon as you can and
check all your tires for damage. (If a tire is ¯at, see
If a Tire Goes Flat on page 5-78). Also, check the
tire pressure in all four tires as soon as you can.
See
In¯ation -- Tire Pressure on page 5-69.
The CHECK TIRE PRESSURE warning message will
also be displayed (while the ignition is on) until you reset
(calibrate) the system. To reset the system, see ªTire
In¯ation Monitor Systemº under the options mode in
DIC
Controls and Displays on page 3-45.
Don't reset the tire in¯ation monitor system without ®rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the system will not work properly and may not alert you
when a tire is low.
Any time you adjust a tire's pressure, rotate your tires,
or have one or more tires repaired or replaced, you'll
need to reset (calibrate) the tire in¯ation monitor system.
You'll also need to reset the system whenever you
buy new tires and whenever the vehicle's battery has
been disconnected.
5-70

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 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. See
When It Is Time
for New Tires on page 5-72andWheel Replacement
on page 5-75for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See ªPart A: Scheduled
Maintenance Services,º in Section 6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts
are properly tightened. See ªWheel Nut Torqueº under
Capacities and Speci®cations on page 5-104.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any 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 you need to, to
get all the rust or dirt off. See ªChanging a Flat
Tireº in the Index.
5-71

Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
See
Changing a Flat Tire on page 5-78for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been
used or how far it's been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.

If a Tire Goes Flat
It's unusual for a tire to ªblowoutº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowoutº, 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 you'd 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 Ð well off the road if possible.
If a tire goes ¯at, the next part shows how to use your
jacking equipment to change a ¯at tire safely.
Changing a Flat Tire
If a tire goes ¯at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ¯ashers.
{CAUTION:
Changing a tire can cause an injury. The
vehicle can slip off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake ®rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
CAUTION: (Continued)
5-78

Removing Wheel Nut Caps
If there is a wheel cover,
loosen the plastic nut caps
with the wheel wrench.
They won't come off.
Then, using the ¯at end of
the wheel wrench, pry
along the edge of the cover
until it comes off.
Removing the Flat Tire and Installing
the Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.
2. Turn the jack handle clockwise to raise the vehicle.
Raise the vehicle far enough off the ground for the
spare tire to ®t underneath the wheel well.
5-82

Storing the Flat Tire and Tools
{CAUTION:
Storing a jack, a tire, 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 all these in the proper place.
After you've put the compact spare tire on your vehicle,
you'll need to store the ¯at tire in the trunk. Use the
following procedure to secure the ¯at tire in the trunk.
When storing a full-size tire, you must use the extension
to help avoid wheel surface damage. Use the extension
and protector/guide located in the foam holder. To store a
full-size tire, place the tire in the trunk valve stem facing
down, with the protector/guide placed through a wheel
bolt hole. Remove the protector and attach the retainer
securely. When putting the compact spare back in the
trunk, place the protector/guide back in the foam holder.
Store the cover as far forward as possible.
