to obtain service, see your
vehicle Warranty booklet
for details. For additional
information refer to the tire
manufacturer.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your

8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5.
9. After hearing the conrming horn
chirp for the driver side rear tire,
check to see if the TPMS low tire
warning light and the DIC LOW
TIRE messages have turned off.
If yes, the TPMS sensors have
been relearned. Turn the ignition
switch to LOCK/OFF.
If the low tire warning light and
the SERV TPM message on the

Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire,
for signs of wear or damage.
SeeWhen It Is Time for
New Tires on page 5-58for
more information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km).
SeeScheduled Maintenance
on page 6-4.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the
vehicle continues to perform
most like it did when the
tires were new.Any time you notice unusual
wear, rotate the 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 5-58and
Wheel Replacement on
page 5-64.
Make sure the spare tire is
stored securely. Push, pull and
then try to rotate or turn the
tire. If it moves, use the wheel
wrench/hoist shaft to tighten
the cable. SeeChanging a
Flat Tire on page 5-66.
Service and Appearance Care 5-57

Tire Chains
{CAUTION
If your vehicle has LT285/75R16
or P265/65R18 size tires, do not
use tire chains. They can damage
your vehicle because 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 your 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 your
vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions.
To help avoid damage to your
vehicle, drive slowly, readjust,
or remove the device if it is
contacting your vehicle, and do
not spin your vehicle’s wheels.
If you do nd traction devices
that will t, install them on the
rear tires.Notice:If your vehicle has a
tire size other than LT285/75R16
or P265/65R18 use tire chains
only where legal and only when
you must. Use chains that are
the proper size for your tires.
Install them on the tires of
the rear axle. Do not use chains
on the tires of the front axle.
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.

Customer Assistance Information 7-7

This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data
is recorded by the EDR under
normal driving conditions and no
personal data (e.g., name, gender,
age, and crash location) is
recorded. However, other parties,
such as law enforcement, could
combine the EDR data with the type
of personally identifying data
routinely acquired during a crash
investigation.
To read data recorded by an EDR,
special equipment is required,
and access to the vehicle or the
EDR is needed. In addition to
the vehicle manufacturer, other
parties, such as law enforcement,
that have the special equipment, can
read the information if they have
access to the vehicle or the EDR.GM will not access this data or
share it with others except: 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. Data
that GM collects or receives may
also be used for GM research needs
or may be made available to
others for research purposes, where
a need is shown and the data is
not tied to a specic vehicle
or vehicle owner.
OnStar®
If your vehicle has OnStar and you
subscribe to the OnStar services,
please refer to the OnStar Terms and
Conditions for information on data
collection and use. See alsoOnStar

for more information.
Navigation System
If your vehicle has a navigation
system, use of the system may
result in the storage of destinations,
addresses, telephone numbers, and
other trip information. Refer to the
navigation system operating manual
for information on stored data and for
deletion instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some
vehicles for functions such as
tire pressure monitoring and ignition
system security, as well as in
connection with conveniences such
as key fobs for remote door
locking/unlocking and starting, and
in-vehicle transmitters for garage
door openers. RFID technology in
GM vehicles does not use or record
personal information or link with
any other GM system containing
personal information.
