The Tire Pressure Monitor System (TPMS)
operates on a radio frequency and complies
with RSS-210 of Industry and Science Canada.
Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 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.
SeeWhen It Is Time for New Tires on page 499
andWheel Replacement on page 504for
more information.Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the ratchet/wheel wrench to tighten the
cable. SeeChanging a Flat Tire on page 508.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 555.
When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the spare tire in the tire rotation.
497

After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
tire and loading information label. SeeLoading
Your Vehicle on page 390andInation - Tire
Pressure on page 490, for more information.
Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation. See “TPMS
Sensor Identication Codes” underTire Pressure
Monitor System on page 492.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 548.
{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 needed, to get all the rust or
dirt off. SeeChanging a Flat Tire on
page 508.
498

{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 508for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your 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.
505

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 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 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.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle 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. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to use
the jacking equipment to change a at tire
safely.
507

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. SeeHazard
Warning Flashers on page 188for more
information.
{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
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. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear— not in NEUTRAL.
CAUTION: (Continued)
CAUTION: (Continued)
4. Turn off the engine and do not restart
while the vehicle is raised.
5. Do not allow passengers to remain in
the vehicle.
6. Put the wheel blocks at the front and
rear of the tire farthest away from the
one being changed. That would be
the tire on the other side, at the
opposite end of the vehicle.
When your vehicle has a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
508

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to
remove the at tire and raise the vehicle.
1. Remove the center cap, if your vehicle has
one, by placing the chisel end of the wheel
wrench in the slot on the wheel and gently pry
the cap out.
If the wheel has bolt-on wheel covers, loosen
the plastic nut caps by turning the wheel
wrench counterclockwise. If needed, nish
loosening them by hand.The nut caps will not come off. Using the at
end of the wheel wrench, pry along the edge of
the cover until it comes off.
If your vehicle has only wheel nut caps, loosen
the plastic nut caps with the wheel wrench
in a counterclockwise direction. If needed,
nish loosening them by hand.
2. Use the wheel wrench to loosen all the wheel
nuts. Turn the wheel wrench counterclockwise
to loosen the wheel nuts. Do not remove
the wheel nuts yet.
513

Front Tire Flat:If the at tire is on a front tire
of the vehicle, you will need to use the jack
handle (B) and only one jack handle
extension (C). Attach the wheel wrench (D) to
the jack handle extension (C). Attach the
jack handle (B) to the jack (A). Position the jack
on the frame behind the at tire where the
frame sections overlap (E). Turn the wheel
wrench (D) clockwise to raise the vehicle.Raise the vehicle far enough off the ground so
there is enough room for the spare tire to
clear the ground.

Rear Position – 1500 Models
515

Rear Tire Flat:If the at tire is on a rear tire of
the vehicle, you will need to use the jack
handle (B) and both jack handle extensions (C).
Attach the wheel wrench (D) to the jack handle
extensions (C). Attach the jack handle (B) to the
jack (A). Use the jacking pad provided on the
rear axle. Turn the wheel wrench (D) clockwise
to raise the vehicle. Raise the vehicle far
enough off the ground so there is enough room
for the spare tire to clear the ground.4. Remove all of the
wheel nuts.
5. Take off the at tire.
Rear Position – All Other Models
516

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly which has a secondary latch system.
It is designed to stop the spare tire from suddenly
falling off your vehicle. For the secondary latch
to work, the spare tire must be installed with
the valve stem pointing down. SeeStoring a Flat
or Spare Tire and Tools on page 522.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed below.To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if the
cable end is
visible. If the cable
is not visible,
proceed to Step 6.
2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You
cannot overtighten the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
