IN BRIEF 21
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.
SeeForward Automatic Braking (FAB)
0 264.
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 directly 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.
See
Front Pedestrian Braking (FPB)
System 0266.
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) alert
as the lane marking is crossed. The
system will not assist or 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).
See Lane Departure Warning (LDW)
0 272 and
Lane Keep Assist (LKA) 0273.
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers
with avoiding lane change crashes
that occur with moving vehicles in the
side blind zone (or spot) areas or with
vehicles rapidly approaching these
areas from behind. The LCA warning
display will light up in the
corresponding outside mirror and will
flash if the turn signal is on. The Side
Blind Zone Alert (SBZA) system is
included as part of the LCA system.
See Side Blind Zone Alert (SBZA) 0270
and
Lane Change Alert (LCA) 0271.
Surround Vision
If equipped, views around the vehicle
appear in the infotainment display to
aid with parking and low-speed
maneuvers.
See “Surround Vision ”under
Assistance Systems for Parking or
Backing 0253.

94 SEATS AND RESTRAINTS
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, seePublication Ordering
Information 0410.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐volt
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the airbag
system. Be sure to follow proper
service procedures, and make sure
the person performing work for you
is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly.
The operation of the airbag system
can also be affected by changing,
including improperly repairing or
replacing, any parts of the following:
.
Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
. Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
. Inner door seals, including
speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors, sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 090.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0356 for additional important
information.
