SeeForward Collision Alert (FCA)
System 0308.
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.
See Forward Automatic Braking
(FAB) 0310.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
unintentional lane departures at
speeds of 56 km/h (35 mph) or
greater. LDW uses a camera sensor
to detect the lane markings. The
LDW light,
@, is green if a lane marking is detected. If the vehicle
departs the lane, the light will
change to amber and flash. In
addition, beeps will sound or the
driver seat will pulse.
See
Lane Departure Warning (LDW)
(2500/3500 Series) 0312.
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)
(2500/3500 Series) 0312 andLane
Keep Assist (LKA) (1500 Series)
0 313.
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 0306.
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.
The vehicle may also have the Front
Parking Assist system.
See Assistance Systems for Parking
or Backing 0306.
