If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have
the right wheel, wheel bolts, wheel nuts, and TPMS
sensors 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.
SeeChanging a Flat Tire on page 5-104for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how
far it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel,
use a new GM original equipment wheel.

Tire Chains
{CAUTION:
If your VEHICLE has P255/45R17, P255/45ZR18,
P275/40R19, or 255/45ZR18 size tires, do not use
tire chains, as there is not enough clearance.
Tire chains used on a vehicle without the proper
amount of clearance can cause damage to the
brakes, suspension, or other vehicle parts.
The area damaged by the tire chains could
cause you to lose control of the vehicle and
you or others may be injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
CAUTION: (Continued)
CAUTION: (Continued)
conditions. Follow that manufacturer’s instructions.
To help avoid damage to the vehicle, drive slowly,
readjust, or remove the device if it is contacting
the vehicle, and do not spin the vehicle’s wheels.
If you do nd traction devices that will t, install
them on the rear tires only.
Notice:If your vehicle has P235/50R17 size tires,
use tire chains only where legal and only when you
must. Use only SAE Class S-type chains that are
the proper size for your tires. Install them on the rear
tires and tighten them as tightly as possible with
the ends securely fastened. Drive slowly and follow
the chain manufacturer’s instructions. If you can
hear the chains contacting your vehicle, stop
and retighten them. If the contact continues, slow
down until it stops. Driving too fast or spinning the
wheels with chains on will damage your vehicle.

Lifting the Vehicle (STS-V)
{CAUTION:
Lifting a vehicle 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 lift your vehicle. To help
prevent the vehicle from moving:
1. Hold the brake pedal down with your right foot.
2. Move the shift lever in PARK (P) by pressing
the button on the front of the shift lever while
pushing the lever all the way toward the front
of the vehicle. Release the button.
3. With your right foot still holding the brake
pedal down, set the parking brake with your
left foot.
4. Turn off the engine.
To be even more certain the vehicle will not move,
you can put blocks in front of and behind the wheels.
Also, seeShifting Into Park on page 2-34and
Parking Brake on page 2-33for additional
information.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising the vehicle with the jack improperly
positioned can damage the vehicle or the vehicle
may fall and cause your or others injury.
If you ever use a jack to lift your vehicle, follow the
instructions that came with the jack, and be sure to
use the correct lifting points to avoid damaging
your vehicle.
5-82
Page 409 of 514
Notice:Lifting your vehicle improperly can damage
your vehicle and result in costly repairs not covered
by your warranty. To lift your vehicle properly, follow
the advice in this part.
To help prevent vehicle damage:
Be sure the jack you are using meets the
weight standards for your vehicle and is in
good working order.
Be sure to place a block or pad between the jack
and the vehicle.
Make sure the jack you are using only contacts
the jacking location lift points and is not leaning
on any other vehicle components such as the
rocker panels, the oor pan, or the stone guard
moldings.
Lift only in the areas shown in the following
pictures.
Lifting From the Front
The front lifting points can be accessed from either side
of your vehicle, behind the front tires.
1. Locate the front lifting points using the diagram
above. The front lifting location is about 15 inches
(37 cm) from the rear edge of the front wheel well.
2. Place a block or pad between the jack and
the vehicle.
3. Lift the vehicle with the jack, making sure the jack
is centered on the front lifting point.
5-83
Page 410 of 514
Lifting From the Rear
The rear lifting points can be accessed from either side
of your vehicle, in front of the rear tires.
1. Locate the rear lifting points using the diagram
above. The rear lifting location is about 7 inches
(17 cm) from the front edge of the rear wheel well.2. Place a block or pad between the jack and the
vehicle.
3. Lift the vehicle with the jack, making sure the jack
is centered on the rear lifting point.
SeeDoing Your Own Service Work on page 5-4.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your tires properly. SeeTires
on page 5-54. 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 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.
5-84
Page 411 of 514
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.
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 3-6.
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 5-104.
To use the tire sealant and compressor kit, see
Tire Sealant and Compressor Kit on page 5-87.
5-85
Page 414 of 514
{CAUTION:
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, see
Engine Exhaust on page 2-36.
{CAUTION:
Over-in ating 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 in ate the tire to its recommended
pressure. Do not exceed the recommended
pressure.
{CAUTION:
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
1 4inch (6 mm) in the
tread area of the tire. It can also be used to in ate
an under in ated 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. SeeRoadside Service on
page 7-7.
5-88

15. If the at tire was
able to in ate to the
recommended in ation
pressure, remove the
maximum speed label
from the sealant
canister (B) and place
it in a highly visible
location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.
16. Return the equipment to its original storage location
in the vehicle.
17. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.
18. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
In ate a Tire (Not Punctured).”If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended in ation pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Service on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended in ation
pressure, in ate the tire to the recommended
in ation pressure.
19. Wipe off any sealant from the wheel, tire, and
vehicle.
20. Dispose of the used sealant canister (B) and
sealant/air hose (F) assembly at a local dealer/
retailer or in accordance with local state codes
and practices.
21. Replace it with a new canister available from your
dealer/retailer.
22. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.
