2009 GMC ACADIA wheel

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
Do not use tire chains. 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.
(Continued)
CAUTION (Continued)
Use another type of traction
device only if its manufacturer
recommends it for use on the
vehicle and tire size combination
and road 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 front tires.

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially
if you maintain the tires properly.
SeeTires on page 5-35.Ifair
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 youwould 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 3-5.
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 5-69. To use the
tire sealant and compressor kit,
seeTire Sealant and Compressor
Kit on page 5-56.
Service and Appearance Care 5-55

Tire Sealant and
Compressor Kit
{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, seeEngine
Exhaust on page 2-30.
{CAUTION
Over-inating 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
inate 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
14inch (6 mm)
in the tread area of the tire. It can
also be used to inate an under
inated 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 Assistance
Program on page 7-6.
Read and follow all of the tire
sealant and compressor kit
instructions.
5-56 Service and Appearance Care

17. Return the equipment to its
original storage location in
the vehicle.
18. Immediately drive the vehicle
5 miles (8 km) to distribute the
sealant in the tire.
19. 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 Inate a Tire
(Not Punctured).”
If the tire pressure has fallen
more than 10 psi (68 kPa) below
the recommended ination
pressure, stop driving the vehicle.
The tire is too severely damaged
and the tire sealant cannot seal
the tire. SeeRoadside Assistance
Program on page 7-6.
If the tire pressure has not
dropped more than 10 psi
(68 kPa) from the recommended
ination pressure, inate the tire
to the recommended ination
pressure.20. Wipe off any sealant from the
wheel, tire, and vehicle.
21. Dispose of the used sealant
canister (E) and sealant/air
hose (F) assembly at a
local dealer/retailer or in
accordance with local state
codes and practices.
22. Replace it with a new
canister available from
your dealer/retailer.
23. 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.
