dealer or authorized tire service
center should mount or
dismount the tires.
{Warning
Mixing tires of different sizes (other
than those originally installed on
the vehicle), brands, or types may
cause loss of control of the vehicle,
resulting in a crash or other vehicle
damage. Use the correct size, brand,
and type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel rim
flanges to develop cracks after
many miles of driving. A tire
and/or wheel could fail suddenly
(Continued)
Warning (Continued)
and cause a crash. Use only
radial-ply tires with the wheels
on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size, load
range, speed rating, and
construction (radial) as the
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. See Tire Pressure Monitor
Operation 0349.
The Tire and Loading Information
label indicates the original
equipment tires on the vehicle.
See Vehicle Load Limits 0197.Different Size Tires and
Wheels
If wheels or tires are installed that are
a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be affected.
{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This increases
the chance of a crash and serious
injury. Only use GM specific wheel
and tire systems developed for the
vehicle, and have them properly
installed by a GM certified
technician.

vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your
dealer or an authorized tire service
center repair or replace the flat tire
as soon as 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(Continued)

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, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard Warning
Flashers 0169.
{Warning
Changing a tire can be dangerous.
The vehicle can slip off the jack and
roll over or fall causing injury or
death. Find a level place to change
the tire. To help prevent the vehicle
from moving:
1. Set the parking brake firmly. (Continued)
Warning (Continued)
2. Put an automatictransmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks, if equipped, on both sides of
the tire at the opposite corner
of the tire being changed.
When the vehicle has a flat tire (2),
use the following example as a guide
to assist in the placement of the
wheel blocks (1), if equipped.

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 a crash. When
changing a wheel, remove any rust
or dirt from places where the wheel
attaches to the vehicle. In an
emergency, a cloth or a paper towel

Caution
If the jumper cables are connected
or removed in the wrong order,
electrical shorting may occur and
damage the vehicle. The repairs
would not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the
correct order, making sure that the
cables do not touch each other or
other metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it
to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash or
hook to suspension components.
Use the proper straps around the
tires to secure the vehicle. Do not
drag a locked wheel/tire while
loading the vehicle. Do not use a
sling type lift to tow the vehicle.
This could damage the vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach angles,
if necessary. A towed vehicle should
have its drive wheels off the ground.
Contact Roadside Service or a
professional towing service if the
disabled vehicle must be towed.
If the vehicle is equipped with a tow
eye, it is located in the trunk next to
the spare tire tools. Only use the tow
eye to pull the vehicle onto a flatbed car carrier from a flat road surface. Do
not use the tow eye to pull the vehicle
from snow, mud, or sand.Caution
Improper use of the tow eye can
cause vehicle damage. Use caution
and low speeds to prevent damage
to the vehicle.
Front Attachment Point
Carefully open the cover in the fascia
by using the small notch that conceals
the tow eye socket.
