.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message come on
and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a
new tire/wheel position after rotating
the vehicle’ s tires or replacing one
or more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor.
The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions, using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's LOCK
and UNLOCK buttons at the
same time for approximately
five seconds. The horn sounds
twice to signal the receiver is
in relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen. If the vehicle does not have
RKE, press the Driver
Information Center (DIC) vehicle
information button until the
PRESS
VTO RELEARN TIRE
POSITIONS message displays.
The horn sounds twice to signal
the receiver is in relearn mode
and TIRE LEARNING ACTIVE
message displays on the DIC
screen.
If the vehicle does not have RKE
or DIC buttons, press the trip
odometer reset stem located on
the instrument panel cluster until
the PRESS
VTO RELEARN
TIRE POSITIONS message
displays. The horn sounds twice
to signal the receiver is in
relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.

Tire Chains
{WARNING
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. To help avoid damage to
the vehicle, drive slowly, readjust,
or remove the device if it is
contacting the vehicle. Do not
spin the vehicle's tires. Follow the
manufacturer's instructions.Notice:
Use tire chains only
where legal and only when you
must. Use chains that are the
proper size for the 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 the 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 the vehicle. For Cutaway models with LT245/
75R16, LT225/75R16 or LT215/
85R16 size single or dual rear tires,
use Low Profile Z-Chain or SAE
Class S cables.
For Cargo or Passenger models
with P245/70R17, LT225/75R16 or
LT245/75R16 size tires, use Low
Profile Z-Chain cables. SAE Class S
chains are not recommended.
If the vehicle has dual rear tires,
do not use individual tire chains.
Use tire chains that fit across both
dual tires.

Customer Assistance
Procedure
Owner satisfaction and goodwill are
very important to your dealer and
General Motors.
Normally, any problem with the
transaction, sale, or usage of the
vehicle must be handled by your
dealer sales or service departments.
However, we recognize that despite
the good intentions of all parties
involved, sometimes a
misunderstanding may occur.
If you have a problem that has not
been satisfactorily handled through
the normal means, we suggest the
following steps:
STEP ONE
Explain your case to your dealer
service agent, service manager,
dealer sales agent, or sales
manager, depending on your case.
Make sure that they have all
necessary information. They are
interested in your continual
satisfaction.STEP TWO
If you are not satisfied, please
contact the general manager or your
dealership owner to ask for their
help. If they are not able to resolve
your case, ask them to contact the
right people at General Motors for
support, if needed.
STEP THREE
If your case is not resolved in a
reasonable amount of time by your
dealer, please call the General
Motors Customer Assistance
Center (CAC) and provide the
following information:
.Name
.Address
.Phone number
.Model year
.Brand
.Vehicle Identification
Number (VIN)

Inflates? on page 3‑24.
Managing the Vehicle Damage
Repair Process
In the event that the vehicle requires
damage repairs, GM recommends
that you take an active role in its
repair. If you have a pre-determined
repair facility of choice, take the
vehicle there, or have it towed there.
Specify to the facility that any
required replacement collision parts
be original equipment parts, either
new Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be covered by
the GM vehicle warranty. Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with
the repair professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as the cost stays within
reasonable limits.
