shown on the Tire and Loading
Information label. SeeVehicle Load
Limits 0181.
The low tire pressure warning light
comes on at each ignition cycle until
the tires are inflated to the correct
inflation pressure.
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 must
be inflated to the proper pressure.
A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits 0181, for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0260.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire maintenance. See
Tire Inspection
0 265, Tire Rotation 0265 andTires
0 253.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light
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. The malfunction
light comes on at each ignition cycle until the problem is corrected. Some
of the conditions that can cause this
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 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 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 should go off
when the TPMS sensors are
installed and the sensor

264 Vehicle Care
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 0267.
. 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 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
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
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. Turn the ignition on without
starting the vehicle or place the
vehicle in Service Mode.
See Ignition Positions (Key
Access) 0185 orIgnition
Positions (Keyless Access)
0 188.
3. Press the MENU button to display the menu items in the
Driver Information
Center (DIC).
4. If the vehicle has a base level DIC, use the thumbwheel to
scroll to the Tire Learn menu
item screen.
If the vehicle has an uplevel
DIC, use the thumbwheel to
scroll to the Tire Pressure
menu item screen.
5. Press and hold the SET/CLR button to begin the sensor
matching process.
A message requesting
acceptance of the process may
display.

use one that attaches to the
towing vehicle.
Dinghy Towing
When dinghy towing a vehicle with
an automatic transmission, the
vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To dinghy tow the vehicle from the
front with all four wheels on the
ground:1. Position the vehicle to tow and then secure it to the towing
vehicle.
2. Shift an automatic transmission to P (Park) or a manual
transmission into 1 (First) gear
and turn the ignition off.
3. Set the parking brake.
4. To prevent the battery from draining while the vehicle is
being towed, remove the DLIS
fuse from the instrument panel
fuse block. See Instrument
Panel Fuse Block 0251.
5. For Keyless Access vehicles, to prevent the battery from
draining while the vehicle is
being towed, remove the
BCM1 and BCM2 fuses from
the instrument panel fuse block, and fuse 7 from the
engine compartment fuse
block. See
Instrument Panel
Fuse Block 0251 andEngine
Compartment Fuse Block
0 249.
6. Turn the ignition to ACC/ ACCESSORY.
7. Shift the transmission to N (Neutral).
8. Release the parking brake.
Reinstall the fuses once the
destination has been reached.
Caution
If 105 km/h (65 mph) is exceeded
while towing the vehicle, it could
be damaged. Never exceed
105 km/h (65 mph) while towing
the vehicle.

Global Positioning
System (GPS)
. 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 call OnStar. 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
