Information Center (DIC). See
Driver Information Center
(DIC) (Base Level)0136 or
Driver Information Center
(DIC) (Uplevel) 0139. 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, this
may correct the issue:
.Clean the outside of the
windshield in front of the
rearview mirror.
.Clean the entire front of the
vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
If equipped, the AEB system
may help avoid or reduce the
harm caused by front-end
crashes. AEB also includes
Intelligent Brake Assist (IBA).
When the system detects a
vehicle in the path ahead that
is traveling in the same
direction, and that you may
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
Automatic Emergency Braking
can only occur if a vehicle is
detected. Vehicle detection is
shown by the Forward
Collision Alert (FCA) vehicle
ahead indicator being lit. See
Forward Collision Alert (FCA)
System 0346. The system works when
driving in a forward gear
between 8 km/h (5 mph) and
80 km/h (50 mph), or on
vehicles with Adaptive Cruise
Control (ACC), above 4 km/h
(2 mph). It can detect vehicles
up to approximately 60 m
(197 ft).
{Warning
AEB is an emergency crash
preparation feature and is
not designed to avoid
crashes. Do not rely on AEB
to brake the vehicle. AEB will
not brake outside of its
operating speed range and
only responds to detected
vehicles.
AEB may not:
.Detect a vehicle ahead on
winding or hilly roads.
.Detect all vehicles,
especially vehicles with a
trailer, tractors, muddy
vehicles, etc.

A system unavailable message
may display if:
.The front of the vehicle or
windshield is not clean.
.Heavy rain or snow is
interfering with object
detection.
.There is a problem with the
StabiliTrak/Electronic
Stability Control (ESC)
system.
The AEB system does not
need service.
Front Pedestrian
Braking (FPB) System
If equipped, the FPB system
may help avoid or reduce the
harm caused by front-end
crashes with nearby
pedestrians when driving in a
forward gear. FPB displays an
amber indicator,
~, when a
nearby pedestrian is detected
ahead. When approaching a detected pedestrian too
quickly, FPB provides a red
flashing alert on the
windshield and rapidly beeps
or pulses the driver seat. FPB
can provide a boost to braking
or automatically brake the
vehicle. This system includes
Intelligent Brake Assist (IBA),
and the Automatic Emergency
Braking (AEB) System may
also respond to pedestrians.
See Automatic Emergency
Braking (AEB)
0349.
The FPB system can detect
and alert to pedestrians in a
forward gear at speeds
between 8 km/h (5 mph) and
80 km/h (50 mph). During
daytime driving, the system
detects pedestrians up to a
distance of approximately
40 m (131 ft). During nighttime
driving, system performance is
very limited.
{Warning
FPB does not provide an
alert or automatically brake
the vehicle, unless it detects
a pedestrian. FPB may not
detect pedestrians, including
children:
.When the pedestrian is
not directly ahead, fully
visible, or standing upright,
or when part of a group.
.Due to poor visibility,
including nighttime
conditions, fog, rain,
or snow.
.If the FPB sensor is
blocked by dirt, snow,
or ice.
.If the headlamps or
windshield are not cleaned
or in proper condition.
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving 0242. Keep the

windshield, headlamps, and
FPB sensor clean and in
good repair.
FPB can be set to Off, Alert,
or Alert & Brake through
vehicle personalization. To
view available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.
Detecting the Pedestrian
Ahead
FPB alerts and automatic
braking will not occur unless
the FPB system detects a
pedestrian. When a nearby pedestrian is detected in front
of the vehicle, the pedestrian
ahead indicator will display
amber.
Front Pedestrian Alert
With Head-Up Display
Without Head-Up Display
When the vehicle approaches
a pedestrian ahead too rapidly,
the red FPB alert display will
flash on the windshield. Eight
rapid high-pitched beeps will
sound from the front, or both
sides of the Safety Alert Seat
will pulse five times. When this Pedestrian 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 Front Pedestrian
Alert occurs.
Automatic Braking
If FPB detects it is about to
crash into a pedestrian
directly ahead, and the brakes
have not been applied, FPB
may automatically brake
moderately or brake hard. This
can help to avoid some very
low speed pedestrian crashes
or reduce pedestrian injury.
FPB can automatically brake
to detected pedestrians
between 8 km/h (5 mph) and
80 km/h (50 mph). Automatic
braking levels may be reduced
under certain conditions, such
as higher speeds.

356 Driving and Operating
Lane Keep
Assist (LKA)
If equipped, LKA may help
avoid crashes due to
unintentional lane departures.
This system uses a camera to
detect lane markings. LKA may
be ready to assist at speeds
between 60 km/h (37 mph) and
180 km/h (112 mph). On some
vehicles, the system will
instead operate above
50 km/h (31 mph). LKA may
assist by gently turning the
steering wheel if the vehicle
approaches a detected lane
marking. It may also provide a
Lane Departure Warning
(LDW) alert if the vehicle
unintentionally crosses a
detected lane marking. This
system is not intended to keep
the vehicle centered in the
lane. LKA will not assist or
alert if the turn signal is active
in the direction of lane
departure, or if it detects that
you are accelerating, braking,
or actively steering. LKA canbe overridden by turning the
steering wheel. If the system
detects you are steering
intentionally across a lane
marker, the LDW will not be
given. Do not expect the LDW
to occur when you are
intentionally crossing a lane
marker.
{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.
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
(Continued)
Warning (Continued)
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 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 (Continued)

Front Headlamp
Aiming
Headlamp aim has been preset
and should need no further
adjustment.
If the vehicle is damaged in a
crash, the headlamp aim may
be affected. If adjustment to
the headlamps is necessary,
see your dealer.
Bulb Replacement
LED Lighting
This vehicle has LED lamps.
For replacement of any LED
lighting assembly, contact
your dealer.
Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers to protect
against an electrical system
overload.
When the current electrical
load is too heavy, the circuit
breaker opens and closes,
protecting the circuit until the
current load returns to normal
or the problem is fixed. This
greatly reduces the chance of
circuit overload and fire
caused by electrical problems.

4. If the fuse must bereplaced immediately,
borrow a replacement fuse
with the same amperage
from the fuse block.
Choose a vehicle feature
that is not needed to
safely operate the vehicle.
Repeat Steps 2-3.
5. Insert the replacement fuse into the empty slot of
the blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
Headlamp Wiring
An electrical overload may
cause the lamps to go on and
off, or in some cases to remain
off. Have the headlamp wiring
checked right away if the
lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats
due to heavy snow or ice, the
windshield wipers will stop. Wiper function is available
immediately after the wiper
switch is set to off, and back
to on.
To protect the wiper motor
from overheating, the wipers
may slow down when the
windshield is dry for a long
period of time. If a period of
dry operation, or little
moisture, exceeds 10 minutes,
the wipers may switch to
intermittent operation, and
remain there. When moisture
is again detected on the
windshield, wiper operation
will return to the operator
selected speed.
Although the circuit is
protected from electrical
overload, overload due to
heavy snow or ice may cause
wiper linkage damage. Always
clear ice and heavy snow from
the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not
snow or ice, be sure to get it
fixed.
Fuses and Circuit
Breakers
The wiring circuits in the
vehicle are protected from
short circuits by a combination
of fuses and circuit breakers.
This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers
are marked with
their ampere rating. Do not
exceed the
specified amperage rating
when replacing fuses and
circuit breakers. Use of an
oversized fuse or circuit
breaker can result in a
vehicle fire. You and others
could be seriously injured or
killed.

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,
resulting in a crash. Always
use the correct wheel, wheel
bolts, and wheel nuts for
replacement.
{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.
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.
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.
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 slowly and readjust or
remove the traction device if
it contacts the vehicle. Do
not spin the wheels.(Continued)
