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.

22 IN BRIEF
Front Vision Camera
If equipped, a view of the area in front
of the vehicle appears on the
infotainment display to aid with
parking and low-speed maneuvers.
See“Front Vision Camera ”under
Assistance Systems for Parking or
Backing 0253.
Rear Vision Camera (RVC)
If equipped, RVC shows a view of the
area behind the vehicle on the
infotainment display when the vehicle
is shifted into R (Reverse) to aid with
parking and low-speed backing
maneuvers.
See Assistance Systems for Parking or
Backing 0253.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system shows a
triangle with an arrow on the
infotainment display to warn of traffic
behind your vehicle that may cross your vehicle's path while in
R (Reverse). In addition, beeps will
sound, or the driver seat will pulse.
See
Assistance Systems for Parking or
Backing 0253.
Park Assist
If equipped, Rear Park Assist (RPA)
uses sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than 8 km/h
(5 mph). RPA may show a warning
triangle on the infotainment display
and a graphic on the instrument
cluster to provide the object distance.
In addition, multiple beeps or seat
pulses may occur if very close to an
object.
The vehicle may also have the Front
Park Assist system.
See Assistance Systems for Parking or
Backing 0253.
Automatic Parking
Assist (APA)
If equipped, the APA system helps to
search for and maneuver the vehicle
into parallel or perpendicular parking
spots using automatic steering,
displays, and beeps. When the vehicle
speed is below 30 km/h (18 mph),
touch
Oto enable the system.
See “Automatic Parking Assist (APA)”
under Assistance Systems for Parking
or Backing 0253.
Reverse Automatic
Braking (RAB)
If the vehicle has Adaptive Cruise
Control (ACC) it also has the RAB
system, which is designed to help
avoid or reduce the harm caused by
backing crashes when the vehicle is
shifted into R (Reverse). If the system
detects the vehicle is backing too fast
to avoid a crash with a detected object
behind your vehicle in your path, it
may automatically brake hard to
a stop.
