Vehicle Care 269
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
SeeTire Pressure Monitor
Operation 0269.
See Radio Frequency Statement
0 335.Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tires and transmit the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure shown on the Tire and Loading
Information label. See
Vehicle Load
Limits 0166.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed. For
additional information and details
about the DIC operation and
displays see Driver Information
Center (DIC) 0126.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when

Vehicle Care 271
.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 pressure condition. See
your dealer for service if the TPMS
malfunction light and DIC message
comes on and stays 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. The
TPMS sensor matching process
should also 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. A TPMS
relearn tool can also be purchased.
See Tire Pressure Monitor Sensor
Activation Tool at
www.gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
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. Place the vehicle in Service Mode. See Ignition Positions
0 170.
3. Make sure the Tire Pressure info page option is turned on.
The info pages on the DIC can
be turned on and off through
the Options menu. See Driver
Information Center (DIC) 0126. 4. Use the DIC controls on the
right side of the steering wheel
to scroll to the Tire Pressure
screen under the DIC
info page.
5. Press and hold
Vin the center
of the DIC controls.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE
LEARNING ACTIVE message
displays on the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
8. Proceed to the passenger side front tire, and repeat the
procedure in Step 7.
9. Proceed to the passenger side rear tire, and repeat the
procedure in Step 7.

Vehicle Care 307
Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
Use a microfiber cloth on high gloss
surfaces or vehicle displays. First,
use a soft bristle brush to remove
dirt that can scratch the surface.
Then gently clean by rubbing with a
microfiber cloth. Never use window
cleaners or solvents. Periodically
hand wash the microfiber cloth
separately, using mild soap. Do not
use bleach or fabric softener. Rinse
thoroughly and air dry before
next use.
Caution
Do not attach a device with a
suction cup to the display. This
may cause damage and would
not be covered by the vehicle
warranty.
Instrument Panel, Leather,
Vinyl, Other Plastic Surfaces,
Low Gloss Paint Surfaces, and
Natural Open Pore Wood
Surfaces
Use a soft microfiber cloth
dampened with water to remove
dust and loose dirt. For a more
thorough cleaning, use a soft
microfiber cloth dampened with a
mild soap solution.
Caution
Soaking or saturating leather,
especially perforated leather, as
well as other interior surfaces,
may cause permanent damage.
Wipe excess moisture from these
surfaces after cleaning and allow
them to dry naturally. Never use
heat, steam, or spot removers. Do
not use cleaners that contain
silicone or wax-based products.
Cleaners containing these
solvents can permanently change(Continued)
Caution (Continued)
the appearance and feel of
leather or soft trim, and are not
recommended.
Do not use cleaners that increase
gloss, especially on the instrument
panel. Reflected glare can decrease
visibility through the windshield
under certain conditions.
Caution
Use of air fresheners may cause
permanent damage to plastics
and painted surfaces. If an air
freshener comes in contact with
any plastic or painted surface in
the vehicle, blot immediately and
clean with a soft cloth dampened
with a mild soap solution.
Damage caused by air fresheners
would not be covered by the
vehicle warranty.

Customer Information
Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Buick. Normally, any concerns with
the sales transaction or the
operation of the vehicle will be
resolved by your dealer's sales or
service departments. Sometimes,
however, despite the best intentions
of all concerned, misunderstandings
can occur. If your concern has not
been resolved to your satisfaction,
the following steps should be taken:
STEP ONE : Discuss your concern
with a member of dealership
management. Normally, concerns
can be quickly resolved at that level.
If the matter has already been
reviewed with the sales, service,
or parts manager, contact the owner
of your dealership or the general
manager.
STEP TWO : If after contacting a
member of dealership management,
it appears your concern cannot be

Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to
monitor the conditions for airbag
deployment and deploy them in a
crash, and, if equipped, to provide
antilock braking to help the driver
control the vehicle. These modules
may store data to help the dealer
technician service the vehicle.
Some modules may also store data
about how the vehicle is operated,
such as rate of fuel consumption or
average speed. These modules may
retain personal preferences, such as
radio presets, seat positions, and
temperature settings.
