the engine compartment fuse
block. The electric trailer brake
controller should be installed
by your dealer or a qualified
service center.
Trailer Lamps
Always check that all trailer
lamps are working at the
beginning of each trip, and
periodically on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak/
Electronic Stability Control
(ESC) have a Trailer Sway
Control (TSC) feature. Trailer
sway is unintended
side-to-side motion of a trailer
while towing. If the vehicle is
towing a trailer and the TSC
detects that sway is
increasing, the vehicle brakes
are selectively applied to help
reduce excessive trailer sway.
If equipped with the
Integrated Trailer Brake
Control (ITBC) system, and the
trailer has an electric brake
system, StabiliTrak/ESC may
also apply the trailer brakes.
If TSC is enabled, the Traction
Control System (TCS)/
StabiliTrak/ESC warning light
will flash on the instrument
cluster. Reduce vehicle speed
by gradually removing your
foot from the accelerator
pedal. If trailer sway continues,
StabiliTrak/ESC can reduce
engine torque to help slow the
vehicle. TSC will not function if
StabiliTrak/ESC is turned off.
See Traction Control/
Electronic Stability Control
0276.
{Warning
Trailer sway can result in a
crash and in serious injury or
death, even if the vehicle is
equipped with TSC.
If the trailer begins to sway,
reduce vehicle speed by
gradually removing your foot
from the accelerator. Then
pull over to check the trailer
and vehicle to help correct
possible causes, including an

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 Tires0419.
.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 come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual
and audible alerts outside the
vehicle to help when inflating
an underinflated tire to the
recommended cold tire
pressure.
When the low tire pressure
warning light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn
signal lamp will flash. When the recommended
pressure is reached, the
horn sounds once and the
turn signal lamp will stop
flashing and briefly turn
solid.
Repeat these steps for all
underinflated tires that have
illuminated the low tire
pressure warning light.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Do not exceed the
maximum pressure listed on
the tire sidewall. See Tire
Sidewall Labeling 0402 and
Vehicle Load Limits 0252.
If the tire is overinflated by
more than 35 kPa (5 psi), the
horn will sound multiple times
and the turn signal lamp will
continue to flash for several
seconds after filling stops. To
release and correct the
pressure, while the turn signal

Vehicle Care 415
lamp is still flashing, briefly
press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does
not flash within 15 seconds
after starting to inflate the
tire, the tire fill alert has not
been activated or is not
working.
If the hazard warning flashers
are on, the tire fill alert visual
feedback will not work
properly.
The TPMS will not activate the
tire fill alert properly under the
following conditions:
.There is interference from
an external device or
transmitter.
.The air pressure from the
inflation device is not
sufficient to inflate the tire.
.There is a malfunction in
the TPMS.
.There is a malfunction in the
horn or turn signal lamps.
.The identification code of
the TPMS sensor is not
registered to the system.
.The battery of the TPMS
sensor is low.
If the tire fill alert does not
operate due to TPMS
interference, move the vehicle
about 1 m (3 ft) back or
forward and try again. If the
tire fill alert feature is not
working, use a tire pressure
gauge.
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.

416 Vehicle Care
2. Place the vehicle in ServiceMode. See Ignition
Positions 0257.
3. Make sure the Tire Pressure info display
option is turned on. The
info displays on the DIC
can be turned on and off
through the Options menu.
See Driver Information
Center (DIC) 0144.
4. Use the five-way DIC control on the right side of
the steering wheel to scroll
to the Tire Pressure
screen under the DIC info
page. See Driver
Information Center (DIC)
0144.
5. Press and hold the thumbwheel in the center
of the five-way DIC control.
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
Step 7.
9. Proceed to the passenger side rear tire, and repeat
Step 7.
10. Proceed to the driver side rear tire, and repeat
Step 7. 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.
11. Turn the vehicle off.
12. Set all four tires to the recommended air pressure
level as indicated on the
Tire and Loading
Information label.
Tire Inspection
We recommend that the
tires, including the spare
tire, if the vehicle has one,
be inspected for signs of
wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or
more places around the
tire can be seen.
.There is cord or fabric
showing through the
tire's rubber.

.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels
and underpasses; or in an
area with very dense trees.
If GPS signals are not
available, the OnStar system
should still operate to callOnStar. However, OnStar
could have difficulty
identifying the exact
location.
.In emergency situations,
OnStar can use the last
stored GPS location to send
to emergency responders.
A temporary loss of GPS can
cause loss of the ability to
send a Turn-by-Turn
Navigation route. The Advisor
may give a verbal route or may
ask for a call back after the
vehicle is driven into an
open area.
Cellular and GPS
Antennas
Cellular reception is required
for OnStar to send remote
signals to the vehicle. Do not
place items over or near the
antenna to prevent blocking
cellular and GPS signal
reception.
