Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under‐inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. 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.

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 transmits 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.

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. When
the system detects a malfunction, the low tire pressure
warning light flashes for about one minute and then
stays on for the remainder of the ignition cycle. A DIC
warning message also displays. The malfunction light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause these to come on are:
.One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The malfunction light and the DIC message
should go off after the road tire is replaced and
the sensor matching process is performed
successfully. See "TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching process was not done
or not completed successfully after rotating the
tires. The malfunction light and the DIC message
should go off after successfully completing the
sensor matching process. See "TPMS Sensor
Matching Process" later in this section.
.One or more TPMS sensors are missing or
damaged. The malfunction light and the DIC
message should go off when the TPMS sensors
are installed and the sensor matching process is
performed successfully. See your dealer for
service.
.Replacement tires or wheels do not match the
original equipment tires or wheels. Tires and
wheels other than those recommended could
prevent the TPMS from functioning properly. See
Buying New Tires on page 6‑72.
.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
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. 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. 4. Start with the driver side front tire.
5. 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.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. SeeWhen It Is Time for New
Tires
on page 6‑71for more information.
Always remove the tires if any of the following
statements are true:
.You can see the indicators at three or more
places around the tire.
.You can see cord or fabric showing through
the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show cord or
fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Tires should be rotated every 12 000 km
(7,500 miles). See Scheduled Maintenance
on
page 7‑3
. The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your 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. See
When It Is Time for New Tires
on
page 6‑71
and Wheel Replacementon page 6‑76.
When rotating the vehicle's tires, always use the
correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
6-70

Black plate (71,1)Buick Lucerne Owner Manual - 2011
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. SeeInflation - Tire
Pressure
on page 6‑64and Loading the Vehicleon
page 5‑18
.
Reset the Tire Pressure Monitor System. See Tire
Pressure Monitor Operation
on page 6‑66.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications
on page 6‑116.
{WARNING:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if needed, to get all the rust or dirt off. See
Changing a Flat Tire
on page 6‑88. Lightly coat the center of the wheel hub with
wheel bearing grease after a wheel change or tire
rotation to prevent corrosion or rust build-up. Do
not get grease on the flat wheel mounting surface
or on the wheel nuts or bolts.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining. See
Tire
Inspection and Rotation
on page 6‑70for
additional information.
6-71

Black plate (73,1)Buick Lucerne Owner Manual - 2011
GM recommends replacing tires in sets of four.
This is because uniform tread depth on all tires
will help keep your vehicle performing most like
it did when the tires were new. Replacing less
than a full set of tires can affect the braking
and handling performance of your vehicle. See
Tire Inspection and Rotation
on page 6‑70for
information on proper tire rotation.
{WARNING:
Tires could explode during improper service.
Attempting to mount or dismount a tire could
cause injury or death. Only your dealer or
authorized tire service center should mount or
dismount the tires.
{WARNING:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes, brands, or types (radial and
bias-belted tires), the vehicle may not handle
properly, and you could have a crash. Using
tires of different sizes, brands, or types may
also cause damage to your vehicle. Be sure
to use the correct size, brand, and type of
tires on all wheels. It is all right to drive with
your compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire
on page 6‑97.
6-73

Black plate (74,1)Buick Lucerne Owner Manual - 2011
{WARNING:
Using bias-ply tires on the vehicle may
cause the wheel rim flanges to develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly and cause
a crash. Use only radial-ply tires with the
wheels on the vehicle.
If you must replace your vehicle's tires with those
that do not have a TPC Spec number, make sure
they are the same size, load range, speed rating,
and construction type (radial and bias‐belted tires)
as your vehicle's original tires.
Vehicles that have a tire pressure monitoring
system could give an inaccurate low‐pressure
warning if non‐TPC Spec rated tires are installed
on your vehicle. Non‐TPC Spec rated tires may
give a low‐pressure warning that is higher or lower
than the proper warning level you would get with
TPC Spec rated tires. See Tire Pressure Monitor
System
on page 6‑65. Your vehicle's original equipment tires are listed
on the Tire and Loading Information Label. See
Loading the Vehicle
on page 5‑18, for more
information about the Tire and Loading
Information Label and its location on your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle has
electronic systems such as, antilock brakes, traction
control, and electronic stability control, the performance
of these systems can be affected.
{WARNING:
If different sized wheels are used, there may not
be an acceptable level of performance and safety
if tires not recommended for those wheels are
selected. This increases the chance of a crash
and serious injury. Only use GM specific wheel
and tire systems developed for the vehicle, and
have them properly installed by a GM certified
technician.
6-74

Black plate (76,1)Buick Lucerne Owner Manual - 2011
Traction–AA, A, B, C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead
braking traction tests, and does not include
acceleration, cornering, hydroplaning, or peak
traction characteristics.
Temperature –A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum required by law. Warning: The
temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive
loading, either separately or in combination, can
cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you
the longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing will
not be necessary on a regular basis. However, if you
notice unusual tire wear or your vehicle pulling to
one side or the other, the alignment might need to be
checked. If you notice your vehicle vibrating when
driving on a smooth road, the tires and wheels might
need to be rebalanced. See your dealer for proper
diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming loose,
the wheel, wheel bolts, and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
