Canada/Mexico-15555988) - 2022 - CRC - 12/3/21
Driving and Operating 257
{Warning
IBA may increase vehicle braking in
situations when it may not be necessary.
You could block the flow of traffic. If this
occurs, take your foot off the brake pedal
and then apply the brakes as needed.
AEB and IBA can be disabled through vehicle
personalization. See “Collision/Detection
Systems” underVehicle Personalization
0 130.
{Warning
Using AEB or IBA while towing a trailer
could cause you to lose control of the
vehicle and crash. Turn the system to
Alert or Off when towing a trailer.
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 pedestrians near the forward
path of the vehicle 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) 0256.
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 0192. Keep the
windshield, headlamps, and FPB sensor
clean and in good repair.
FPB can be set to Off, Alert, or Alert and
Brake through vehicle personalization. See
“Collision/Detection Systems” underVehicle
Personalization 0130.

Canada/Mexico-15555988) - 2022 - CRC - 12/3/21
268 Driving and Operating
If equipped, the following driver assistance
features should be turned to alert or off
when towing a trailer, unless equipped with
Super Cruise:
.Automatic Emergency Braking (AEB)
.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
When towing a trailer, exhaust gases
may collect at the rear of the vehicle and
enter if the liftgate, trunk/hatch,
or rear-most window is open. (Continued)
Warning (Continued)
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.
.Also adjust the climate control system
to a setting that brings in only outside
air. See“Climate Control Systems” in
the Index.
For more information about carbon
monoxide, see Engine Exhaust 0211.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Get used to the handling and braking
of the combination by driving on a level
road surface before driving on public roads.
The trailer structure, the tires, and the
brakes must be all be rated to carry the
intended cargo. Inadequate trailer
equipment can cause the combination to
operate in an unexpected or unsafe manner.
Before driving, inspect all trailer hitch parts
and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. See
Towing Equipment
0274. If the trailer has
electric brakes, start the combination
moving and then manually apply the trailer
brake controller to check the trailer brakes
work. During the trip, occasionally check
that the cargo and trailer are secure and
that the lamps and any trailer brakes are
working.Towing with a Stability Control System
When towing, the stability control system
might be heard. The system reacts to
vehicle movement caused by the trailer,
which mainly occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving without a
trailer. This can help to avoid heavy braking
and sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination of the
vehicle and trailer will not accelerate as
quickly and is much longer than the vehicle
alone. It is necessary to go much farther

360 Vehicle Care
11. Start the vehicle with the good batteryand run the engine for a while.
12. Try to start the vehicle that had the dead battery. If it will not start after a
few tries, it probably needs service.
Caution
If the jumper cables are connected or
removed in the wrong order, electrical
shorting may occur and damage the
vehicle. The repairs would not be covered
by the vehicle warranty. Always connect
and remove the jumper cables in the
correct order, making sure that the cables
do not touch each other or other metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it to idle
for several minutes.
Towing the Vehicle
Caution
Incorrectly transporting a disabled vehicle
may cause damage to the vehicle. Use
proper tire straps to secure the vehicle to
the flatbed tow truck. Do not strap or
hook to any frame, underbody,
or suspension component not specified
below. Do not move vehicles with drive
axle tires on the ground. Damage is not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with an
electric parking brake and/or an
electronic shifter. In the event of a loss of
12-volt battery power, the electric parking
brake cannot be released, and the vehicle
cannot be shifted to N (Neutral). Tire
skates or dollies must be used under the
non-rolling tires to prevent damage while
loading/unloading the vehicle. Dragging
the vehicle will cause damage not
covered by the vehicle warranty.
Caution
The vehicle may be equipped with a tow
eye. Improper use of the tow eye may
cause damage to the vehicle and is not
covered by the vehicle warranty.
If equipped, use the tow eye to load the
vehicle onto a flatbed tow truck from a
flat road surface, or to move the vehicle
a very short distance at a walking pace.
The tow eye is not designed for off-road
recovery. The vehicle must be in
N (Neutral) with the electric parking
brake released when using the tow eye.
Contact a professional towing service if the
disabled vehicle must be transported. GM
recommends a flatbed tow truck to
transport a disabled vehicle. Use ramps to
help reduce approach angles, if necessary.
If equipped, a tow eye may be located near
the spare tire or emergency jack. Do not use
the tow eye to pull the vehicle from the
snow, mud, sand, or ditch. Tow eye threads
may have right or left-hand threads. Use
caution when installing or removing the
tow eye.

Managing the Vehicle Damage Repair
Process
In the event that the vehicle requires
damage repairs, GM recommends that you
take an active role in its repair. If you have
a pre-determined repair facility of choice,
take the vehicle there, or have it towed
there. Specify to the facility that any
required replacement collision parts be
original equipment parts, either new
Genuine GM parts or recycled original GM
parts. Remember, recycled parts will not be
covered by the GM vehicle warranty.
Insurance pays the bill for the repair, but
you must live with the repair. Depending on
your policy limits, your insurance company
may initially value the repair using
aftermarket parts. Discuss this with the
repair professional, and insist on Genuine
GM parts. Remember, if the vehicle is
leased, you may be obligated to have the vehicle repaired with Genuine GM parts,
even if your insurance coverage does not
pay the full cost.
If another party's insurance company is
paying for the repairs, you are not obligated
to accept a repair valuation based on that
insurance company's collision policy repair
limits, as you have no contractual limits
with that company. In such cases, you can
have control of the repair and parts choices
as long as the cost stays within reasonable
limits.
