Spare Tire
Your vehicle, when new, had a fully-inated spare
tire. A spare tire may lose air over time, so
check its ination pressure regularly. See
Ination - Tire Pressure on page 375andLoading
Your Vehicle on page 289for information
regarding proper tire ination and loading your
vehicle. For instruction on how to remove, install
or store a spare tire, seeRemoving the Flat
Tire and Installing the Spare Tire on page 396
andStoring a Flat or Spare Tire and Tools
on page 403.
After installing the spare tire on your vehicle,
you should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire and
its wheel together.
405

Aluminum or Chrome-Plated Wheels
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels.
The repairs would not be covered by your
warranty. Never drive a vehicle equipped with
aluminum or chrome-plated wheels through
an automatic car wash that uses silicone
carbide tire cleaning brushes.
Do not take your vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes. These brushes can also damage
the surface of these wheels.

Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes
this, GM will repair, at no charge to the owner,
the surfaces of new vehicles damaged by
this fallout condition within 12 months or
12,000 miles (20 000 km) of purchase,
whichever occurs rst.

If your vehicle is equipped with StabiliTrak®,
steering performance, including yaw rate, steering
wheel angle, and lateral acceleration, is also
recorded. This information has been used to
improve vehicle crash performance and may be
used to improve crash performance of future
vehicles and driving safety. Unlike the data
recorders on many airplanes, these on-board
systems do not record sounds, such as
conversation of vehicle occupants.
To read this information, special equipment is
needed and access to the vehicle or the device
that stores the data is required. GM will not access
information about a crash event or share it with
others other than:
with the consent of the vehicle owner or,
if the vehicle is leased, with the consent of
the lessee,
in response to an official request of police or
similar government office,
as part of GM’s defense of litigation through
the discovery process, or
as required by law.In addition, once GM collects or receives data,
GM may:
use the data for GM research needs,
make it available for research where
appropriate condentiality is to be maintained
and need is shown, or
share summary data which is not tied to a
specic vehicle with non-GM organizations
for research purposes.
Others, such as law enforcement, may have
access to the special equipment that can read
the information if they have access to the vehicle
or the device that stores the data.
