Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the
outside of the windshield in front of
the camera sensor may correct the
issue.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide a
warning if the vehicle is crossing a
detected lane marking without using
a turn signal in the lane departure
direction. LDW uses a camera
sensor to detect the lane markings.
It only operates at speeds of
56 km/h (35 mph) or greater.
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and either three
beeps will be sounded from the left
or right side, or three Safety Alert
Seat pulses will occur on the left or
right side of the seat, depending on
the lane departure direction. LDWwill not warn if the turn signal is on
in the departure direction, or if a
sharp maneuver is made.
{Warning
The LDW system is an aid to help
the vehicle stay in the driving
lane. It does not steer the vehicle.
The LDW system may not:
.Provide enough time to avoid
a crash.
.Detect lane markings under
bad weather conditions or if
the windshield is dirty.
.Detect lane markings and will
not detect road edges.
.Warn that the vehicle is
crossing a lane marking if the
system does not detect the
lane marking.
If LDW only detects lane
markings on one side of the road,
it will only warn you when (Continued)
Warning (Continued)
departing the lane on the side
where it has detected a lane
marker. Even with LDW, always
keep your attention on the road
and maintain proper vehicle
position within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield clean and do not use
LDW in bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack. The control
indicator will light when LDW is on.

Driving and Operating 9-71
When the vehicle is started, the
LDW indicator on the instrument
cluster will come on briefly.
If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while the
vehicle is traveling at 56 km/h
(35 mph) or greater. If the vehicle
crosses a detected lane marking
without using the turn signal in the
lane departure direction, this
indicator will change to amber and
flash. In addition, three beeps will
be sounded from the left or right
side, or the Safety Alert Seat will
pulse three times on either the left
or right side of the seat, depending
on the lane departure direction.
When the System Does Not
Seem to Work Properly
If the LDW symbol does not appear
when the system is on and the
vehicle is traveling at least 56 km/h
(35 mph):
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{Warning
LDW does not provide a warning
to help avoid a crash, unless it
detects the lane markings. LDW
may not detect the lane markings
if the camera sensor is blocked
by dirt, snow, or ice, or if the
windshield is damaged. It may
also not detect a lane on winding
or hilly roads, or in conditions that
can limit visibility such as fog,
rain, or snow, or if the headlamps
or windshield are not cleaned or
in proper condition. Keep the
windshield, headlamps, and
camera sensors clean and in
good repair.
LDW warnings may occur due to tar
marks, shadows, cracks in the road,
or other road imperfections. This is
normal system operation; the
vehicle does not need service.

add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on thevehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
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.
SeeTire Pressure Monitor
Operation on page 10-66.
See Radio Frequency Statement on
page 13-15.
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 on page 9-16.
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. If the vehicle has DIC buttons, tire pressure levels can be
viewed. For additional information
and details about the DIC operation
and displays, see
Driver Information
Center (DIC) (Base Level) on
page 5-30 orDriver Information
Center (DIC) (Uplevel) on page 5-32
and Tire Messages on page 5-42.
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
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9-16, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10-63.

The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire
maintenance. SeeTire Inspection
on page 10-69, Tire Rotation on
page 10-69 andTires on
page 10-54.
{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 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 10-73.

10-68 Vehicle Care
.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. Uplevel DIC Only: 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 Settings menu. See
Driver Information Center (DIC)
(Base Level) on page 5-30 or
Driver Information Center (DIC)
(Uplevel) on page 5-32. 4. If the vehicle has an uplevel
DIC, use the DIC controls on the
right side of the steering wheel
to scroll to the Tire Pressure
screen under the DIC info page.
If the vehicle has a base level
DIC, use the trip odometer reset
stem to scroll to the Tire
Pressure screen.
5. If the vehicle has an uplevel DIC, press and hold the
V(Set/
Reset) button located in the
center of the DIC controls.
If the vehicle has a base level
DIC, press and hold the trip
odometer reset stem for about
five seconds. A message asking
if the process should begin
should appear. Select yes and
press the trip odometer reset
stem to confirm the selection.
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 sidefront 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.
10. Proceed to the driver side rear tire, and repeat the procedure
in 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 ignition switch to
LOCK/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.
.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.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule on
page 11-3.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment.
