vehicle. This can help avoid or
lessen the severity of crashes when
driving in a forward gear.
SeeFront Automatic Braking (FAB)
System 0209.
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 without using a turn
signal in that direction, the light will
change to amber and flash. In
addition, beeps will sound.
See Lane Departure Warning
(LDW) 0212.
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 side 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)
0 210 andLane Change Alert
(LCA) 0210.
Rear Vision
Camera (RVC)
If equipped, RVC displays a view of
the area behind the vehicle on the
center stack 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 0204.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system uses
a triangle with an arrow displayed
on the RVC screen to warn of traffic behind your vehicle that may cross
your vehicle's path while in
R (Reverse). In addition, beeps will
sound.
See
Assistance Systems for Parking
or Backing 0204.
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
display a warning triangle on the
RVC screen and a graphic on the
instrument cluster to provide the
object distance. In addition, multiple
beeps 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 0204.

SeeSunroof 047.eAssist Features
eAssist®Overview
If the vehicle has eAssist, there are
several additional features that
contribute to increased efficiency.
Vehicles with eAssist have an
automatic engine start/stop 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 will only shut off
automatically part of the time. See
Starting the Engine 0178.
There are two air conditioning
settings available. The comfort
setting maximizes cabin comfort.
The eco setting maximizes
efficiency allowing more frequent,
and longer engine stops than the
comfort setting. See Dual Automatic
Climate Control System 0157. This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. See
Hill Start Assist
(HSA) 0191.
Vehicles with eAssist have a slightly
different instrument cluster, which
includes an AUTO STOP indicator
on the tachometer. See Instrument
Cluster (Base Level Cluster) 0104
or Instrument Cluster (Uplevel
Cluster) 0108.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.
