Forward Collision Alert
(FCA) System
If equipped, FCA may help avoid or
reduce the harm caused by
front-end crashes. FCA provides a
green indicator,
V, when a vehicle
is detected ahead. This indicator
displays amber if you follow a
vehicle much too closely. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps.
See Forward Collision Alert (FCA)
System 0201.
Forward Automatic
Braking (FAB)
If the vehicle has Adaptive Cruise
Control (ACC), it also has FAB.
When the system detects a vehicle
ahead in your path that is traveling
in the same direction that you may be about to crash into, it can
automatically brake the vehicle. This
can help avoid or lessen the
severity of crashes when driving in a
forward gear.
See
Forward Automatic Braking
(FAB) 0203.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
unintentional lane departures at
speeds of 56 km/h (35 mph) or
greater. LDW uses a camera sensor
to detect the lane markings. The
LDW light,
@, is green if a lane
marking is detected. If the vehicle
departs the lane without using a turn
signal in that direction, the light will
change to amber and flash. In
addition, beeps will sound.
See Lane Departure Warning (LDW)

Ending Cruise Control
There are four ways to end cruise
control:
.To disengage cruise control,
step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. To turn off the cruise control,
press
5.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
5is pressed
or the ignition is turned off.
Adaptive Cruise Control
If equipped, Adaptive Cruise Control
(ACC) allows the driver to select the
cruise control set speed and
following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses a radar
sensor. See
Radio Frequency
Statement 0325.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control (ESC)
activates, the ACC may
automatically disengage. When road
conditions allow ACC to be safely
used, the ACC can be turned back
on. If TCS or StabiliTrak/ESC have
been disabled, the ACC will not
engage. See Traction Control/
Electronic Stability Control 0186.
{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid

Warning (Continued)
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see“Alerting the Driver” in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving 0163.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads
or when the sensors are
blocked by snow, ice, or dirt.
The system may not detect

194 Driving and Operating
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when a
vehicle suddenly appears due to
a vehicle ahead changing lanes.
Your vehicle may not stop and
could cause a crash. Use caution
when using ACC. Your complete
attention is always required while
driving and you should be ready
to take action and apply the
brakes.
ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle if:
. The sensors are blocked. .
The Traction Control System
(TCS) or StabiliTrak/ESC system
has activated or been disabled.
. There is a fault in the system.
. The radar falsely reports
blockage when driving in a
desert or remote area with no
other vehicles or roadside
objects. A DIC message may
display to indicate that ACC is
temporarily unavailable.
A message indicating that the cruise
is disengaging will appear on the
DIC and the ACC active symbol will
not be displayed when ACC is no
longer active.
Notification to Resume ACC
ACC will maintain a following gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.
If the stopped vehicle ahead has
driven away and ACC has not been
resumed, the vehicle ahead symbol
will flash as a reminder to check
traffic ahead before proceeding. In
addition, three beeps will sound. See
“Adaptive Cruise Go Notifier”
under “Collision/Detection Systems”
in Vehicle Personalization 0132.
When the vehicle ahead drives
away, press +RES or the
accelerator pedal to resume cruise
control. If stopped for more than
two minutes or if the driver door is
opened, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0184. To resume
ACC and release the EPB, press
the accelerator pedal. ACC can be
resumed when the vehicle is
travelling greater than 25 km/h
(16 mph).
A DIC warning message may
display indicating to shift to P (Park)
before exiting the vehicle. See
Vehicle Messages 0131.

detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other
objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle 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 FCA
sensors clean and in good repair.Collision Alert
When your vehicle approaches
another detected vehicle too rapidly,
the red lights will flash on the
windshield. Also, eight rapid
high-pitched beeps will sound from
the front. When this Collision Alert
occurs, the brake system may
prepare for driver braking to occur
more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Collision Alert occurs.
Tailgating Alert
The vehicle ahead indicator will
display amber when you are
following a detected vehicle ahead
much too closely.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press GAP or
[
to set the FCA timing to Far,
Medium, Near, or on some vehicles,
Off. The first button press shows the
current setting on the DIC.
Additional button presses will
change this setting. The chosen
setting will remain until it is changed
and will affect the timing of both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle
speed. The faster the vehicle speed,
the farther away the alert will occur.
Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.

Driving and Operating 203
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing setting
automatically changes the following
gap setting (Far, Medium, or Near).
Unnecessary Alerts
FCA may provide unnecessary
alerts for turning vehicles, vehicles
in other lanes, objects that are not
vehicles, or shadows. These alerts
are normal operation and the
vehicle does not need service.
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 behind the
rearview mirror, and cleaning the
front of the vehicle where radar
sensors are located, may correct
the issue.
Forward Automatic
Braking (FAB)
If the vehicle has Adaptive Cruise
Control (ACC), it also has FAB.
When the system detects a vehicleahead in your path that is traveling
in the same direction that you may
be about to crash into, it can
automatically brake the vehicle. This
can help avoid or lessen the
severity of crashes when driving in a
forward gear. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. This forward automatic
braking can only occur if a vehicle is
detected. This is shown by the FCA
vehicle ahead indicator being lit.
See
Forward Collision Alert (FCA)
System 0201.
The system works when driving in a
forward gear between 10 km/h
(6 mph) and 180 km/h (112 mph) for
moving vehicles, or between
10 km/h (6 mph) and 55 km/h
(34 mph) for stationary vehicles.
It can detect vehicles up to
approximately 60 m (197 ft).
{Warning
FAB is an emergency crash
preparation feature and is not
designed to avoid crashes. Do
not rely on FAB to brake the
vehicle. FAB will not brake
outside of its operating speed
range and only responds to
detected vehicles.
FAB may not: . Detect a vehicle ahead on
winding or hilly roads.
. Detect all vehicles,
especially vehicles with a
trailer, tractors, muddy
vehicles, etc.
. Detect a vehicle when
weather limits visibility, such
as in fog, rain, or snow.
. Detect a vehicle ahead if it
is partially blocked by
pedestrians or other objects.

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 0272.
. 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
0 172.
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 Settings menu. See Driver
Information Center (DIC) 0129.
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.

276 Vehicle Care
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.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or
odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash.(Continued)
