262 DRIVING AND OPERATING
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press
[to set the
FCA timing to Far, Medium, or 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
timings may not be appropriate for all
drivers and driving conditions.
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).
Following Distance Indicator
The following distance to a moving
vehicle ahead in your path is indicated
in following time in seconds on the
Driver Information Center (DIC). See
Driver Information Center (DIC)
0162.
The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is
out of sensor range, dashes will be
displayed.
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
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 Forward Collision
Alert (FCA), it also has FAB, which
includes Intelligent Brake Assist (IBA).
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 provide a
boost to braking or 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 0260.

DRIVING AND OPERATING 271
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal in
that direction. It may also provide a
Lane Departure Warning (LDW)
system alert as the lane marking is
crossed. The LKA system will not
assist or provide an LDW alert if it
detects that you are actively steering.
Override LKA by turning the steering
wheel. LKA uses a camera to detect
lane markings between 60 km/h (37
mph) and 180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.(Continued)
Warning (Continued)
The LKA and LDW systems
may not:
. Provide an alert or enough
steering assist to avoid a lane
departure or crash.
. Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or headlamps
are blocked by dirt, snow,
or ice, if they are not in
proper condition, or if the sun
shines directly into the
camera.
. Detect road edges.
. Detect lanes on winding or
hilly roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW,
you must steer the vehicle. Always (Continued)
Warning (Continued)
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, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions.
{Warning
Using LKA while towing a trailer or
on slippery roads could cause loss
of control of the vehicle and a
crash. Turn the system off.
How the System Works
The LKA camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LKA on and off, press
A
on the steering wheel.

When on,Ais green if LKA is
available to assist and provide LDW
alerts. It may assist by gently turning
the steering wheel and display
A
as amber if the vehicle approaches a
detected lane marking without using a
turn signal in that direction. It may also provide an LDW alert by
flashing
Aamber as the lane
marking is crossed. Additionally, there
may be three beeps, or the driver seat
may pulse three times, on the right or
left, depending on the lane departure
direction.
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert, chime, or DIC message may
be provided. Move the steering wheel
to dismiss.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
. Close vehicles ahead. .
Sudden lighting changes, such as
when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
A system unavailable message may
display if the camera is blocked. The
LKA system does not need service.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Surround Vision Recorder
If equipped, this system records the
360° camera views to an SD card. Only
images are recorded, no sound. An SD
card will be needed for this system. The recommended SD card is an
8-32GB SDHC card with FAT32 file
system, Class 4 and over.
Insert an SD card into the card reader
in the trunk. Disable recording from
the playback screen before removing
the SD card from the reader. Do not
remove the card while recording is
enabled. This could corrupt the video
file and/or the SD card.
Other files should not be stored on
the same SD card as the surround
vision recorder files. Storing other files
on the same card may increase
recording start up and playback time
or result in a loss of data.

292 DRIVING AND OPERATING
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
your hand to the right. Always back
up slowly and, if possible, have
someone guide you.
Making TurnsCaution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not strike soft
shoulders, curbs, road signs, trees,
or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance. If the trailer turn signal bulbs burn
out, the arrows on the instrument
cluster will still flash for turns. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving on Grades
Reduce speed and shift to a lower gear
before
starting down a long or steep
downgrade. If the transmission is not
shifted down, the brakes might get hot
and no longer work well.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at high altitude on steep
uphill grades, consider the following:
Engine coolant will boil at a lower
temperature than at normal altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle may show
signs similar to engine overheating. To
avoid this, let the engine run while
parked, preferably on level ground,
with the automatic transmission in
P (Park) for a few minutes before turning the engine off. If the overheat
warning comes on, see
Engine
Overheating 0321.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both the
vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes
until the chocks absorb the load.

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 0355.
. 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
0 217.
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) 0162.
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) 0162.
5. Press and hold SEL in the center of the five-way DIC control.

360 VEHICLE CARE
Tire Chains
{Warning
If the vehicle has 265/45R18 size
tires on the rear axle, 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. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the traction
device if it contacts the vehicle. Do
not spin the wheels. If traction
devices are used, install them on
the rear tires.
Caution
If the vehicle is equipped with a tire
size other than 265/45R18 on the
rear, use tire chains only where
legal and only when necessary. Use
low profile chains that add no more
than 10 mm thickness to the tire
tread and inner sidewall. Use chains
that are the proper size for the tires.
Install them on the tires of the rear
axle. Do not use chains on the tires
of the front axle. Tighten them as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues, slow
down until it stops. Driving too fast
or spinning the wheels with chains
on will damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are
maintained properly. SeeTires0340.
If air goes out of a tire, it is much more likely to leak out slowly. But if
there is ever a blowout, here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire creates
a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, and then gently brake to a
stop, well off the road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash. Never
