and rapidly beeps or pulses the driver
seat. FPB can provide a boost to
braking or automatically brake the
vehicle.
SeeFront Pedestrian Braking (FPB)
System 0264.
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)
0 270 and Lane Keep Assist (LKA)
0 271.
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) 0268

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 0254.
Rear Cross Traffic Alert
(RCTA) System

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.

Parking Assist
If equipped, Rear Parking 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.

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),

Oto enable the system.
See “Automatic Parking Assist (APA)”
under Assistance Systems for Parking
or Backing 0254.
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.
See Assistance Systems for Parking or
Backing 0254.
