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. This is shown by the
FCA vehicle ahead indicator
being lit. See Forward Collision
Alert (FCA) System0326.
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 (Continued)
Warning (Continued)
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.
.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.
Complete attention is
always required while
driving, and you should be
ready to take action and (Continued)
Warning (Continued)
apply the brakes and/or
steer the vehicle to avoid
crashes.
AEB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this
happens, AEB may engage the
Electric Parking Brake (EPB)
to hold the vehicle at a stop.
Release the EPB or firmly
press the accelerator pedal.
{Warning
AEB may automatically
brake the vehicle suddenly in
situations where it is
unexpected and undesired.
It could respond to a turning
vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB,
firmly press the accelerator
pedal, if it is safe to do so.

332 Driving and Operating
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.
If this happens, Automatic
Braking may engage the
Electric Parking Brake (EPB)
to hold the vehicle at a stop.
Release the EPB. A firm press
of the accelerator pedal will
also release Automatic
Braking and the EPB.
If equipped with the Night
Vision system, pedestrians
detected by the Night Vision
system will not cause
automatic braking to occur.
{Warning
FPB may alert or
automatically brake the
vehicle suddenly in
situations where it is
unexpected and undesired.
It could falsely alert or brake
for objects similar in shape
or size to pedestrians,
including shadows. This is
normal operation and the
vehicle does not need
service. To override
Automatic Braking, firmly
press the accelerator pedal,
if it is safe to do so.
Automatic Braking can be
disabled through vehicle
settings. To view available

view mirrors, even if not
required.
.Do not tow a trailer during
the first 800 km (500 mi) of
vehicle use to prevent
damage to the engine, axle,
or other parts.
.GM recommends performing
an oil change to the vehicle
before heavy towing.
.Do not drive over 80 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Vehicles can tow in D (Drive).
If the transmission
downshifts too often, a
lower gear may be selected
using Manual Mode. See
Manual Mode0271.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.Park Assist
.Automatic Parking
Assist (APA)
.Reverse Automatic
Braking (RAB)
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that

350 Driving and Operating
Always signal turns well in
advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed and shift to a
lower gear before starting
down a long or steep downhill
grade. If the transmission is
not shifted down, the brakes
may overheat and result in
reduced braking efficiency.
The vehicle 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 higher
altitudes, engine coolant will
boil at a lower temperature
than at lower altitudes. If the
engine is turned off
immediately after towing at
high altitude on steep uphill
grades, the vehicle could show
signs similar to engine
overheating. To avoid this, let
the engine run, preferably onlevel ground, with the
transmission in P (Park) for a
few minutes before turning
the engine off. If the overheat
warning comes on, see Engine
Overheating
0381.
Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer 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, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park).
5. Release the brake pedal.
