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 if you follow 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 0208.
Front Automatic Braking
(FAB) System
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 Front Automatic Braking (FAB)
System 0210.
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.
SeeLane Departure Warning
(LDW) 0213.
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)
0 211 and Lane Change Alert
(LCA) 0211.
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 0205.
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, or the driver seat will pulse.
See Assistance Systems for Parking
or Backing 0205.
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
Rear Vision Camera screen and/or
a graphic on the instrument cluster
to provide the object distance. In
addition, multiple beeps may occur
if very close to an object.
See
Assistance Systems for Parking
or Backing 0205.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two accessory power
outlets: one under the armrest
inside the center console storage,
and one on the rear of the center
floor console.
Open the protective cover to use the
accessory power outlet.

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 may not shut off. See
Starting the Engine0178.
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) 0192.
Vehicles with eAssist include an
AUTO STOP indicator on the
tachometer. See Instrument
Cluster 0106.
The eAssist system uses a high
voltage battery, which is cooled with
air drawn from the vehicle interior.
The cold air intake for the battery is
located behind the rear seat, on the
filler panel. Do not cover the intake.
See Battery - North America 0250.
High Voltage Safety
Information
Vehicles with eAssist have a
standard 12-volt battery and a high
voltage battery. Only a trained
service technician with the proper
knowledge and tools should inspect,
test, or replace the high voltage
battery. See your dealer if the high
voltage battery needs service.
In emergency situations, first
responders can cut the two clearly
labeled cut points in the engine
compartment to disable the high
voltage battery and air bag systems.
Do not cut the high voltage cable.
Automatic Engine Start/
Stop Feature
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn off when the brake
pedal is applied and the vehicle
comes to a complete stop. When
the brake pedal is released, or the

The climate control system will use
the previous setting during a remote
start. The rear defog may come on
during remote start based on cold
ambient conditions. The rear defog
indicator light does not come on
during remote start. See“Remote
Start Climate Control Operation” in
Dual Automatic Climate Control
System 0157. Vehicles with heated
or heated and ventilated front seats
can have this feature turn on
automatically during a remote start.
See “Remote Start Auto Heat Seats”
and “Remote Start Auto Cool Seats”
under Vehicle
Personalization 0139.
Extending Engine Run Time
The engine run time can also be
extended by another 10 minutes,
if during the first 10 minutes
Steps 1–2 are repeated while the
engine is still running. An extension
can be requested, 30 seconds after
starting. This provides a total of
20 minutes.
The remote start can only be
extended once. When the remote start is extended,
the second 10-minute period is
added on to the first 10 minutes for
a total of 20 minutes.
A maximum of two remote starts,
or a remote start with an extension,
are allowed between ignition cycles.
The vehicle's ignition must be
changed to ON/RUN/START and
then back to OFF before the remote
start procedure can be used again.

Head Restraints
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for

adjusted properly.
If your vehicle has rear head
restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
