22 In Brief
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) 0253.
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)
0 256 andLane Keep Assist (LKA)
0 257.
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)
0 254 andLane Change Alert (LCA)
0 255.
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 0248.
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 0248.

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.

remain off.
See Traction Control/Electronic
Stability Control 0234.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits
0204. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 333.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure. See “Tire Fill Alert (If
Equipped)” underTire Pressure
Monitor Operation 0334.
