20 In Brief
Forward Collision Alert
(FCA) System
If equipped, FCA may help avoid or
reduce the harm caused by
front-end crashes. FCA provides a
green indicator,
V, when a vehicle
is detected ahead. This indicator
displays amber when following a
vehicle much too closely. When
approaching a vehicle ahead too
quickly, FCA provides a flashing red
alert on the windshield and rapidly
beeps or pulses the driver seat.
See Forward Collision Alert (FCA)
System 0214.
Forward Automatic
Braking (FAB)
If the vehicle has Adaptive Cruise
Control (ACC), 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) 0216.
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 0218.
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)
0 222 andLane Keep Assist (LKA)
0 222.
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.
SeeSide Blind Zone Alert (SBZA)

Rear Vision
Camera (RVC)
RVC displays 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 0210.
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 0210.
Parking 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 display 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.
See Assistance Systems for Parking
or Backing 0210.
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, DIC displays, and beeps.
When the vehicle speed is below
30 km/h (18 mph), press
Oto
enable the system.

eAssist Features
eAssist Overview
Vehicles with the 2.5L engine have
eAssist, with additional features that
contribute to increased efficiency.
Vehicles with eAssist have an
automatic engine Stop/Start feature.
This feature saves fuel by shutting
the engine off when the vehicle is
stopped. When the engine shuts off
automatically, all the accessories
will continue to operate normally. In
very hot or cold conditions, the
engine may not shut off. See
Starting the Engine 0177.
There are two air conditioning
settings available. The MAX setting
maximizes cabin comfort. The ECO
setting maximizes efficiency
allowing more frequent, and longer
engine stops than the MAX setting.
See Dual Automatic Climate Control
System 0157.
Vehicles with eAssist include an
AUTO STOP indicator on the
tachometer. See Instrument Cluster
0 114.
