IN BRIEF 21
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 0228.
Night Vision System
If equipped, this system can help the
driver see and alert the driver to
pedestrians or large animals ahead of
the vehicle beyond the area lit by the
headlamps.
See Night Vision System 0234.
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) 0230.
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 0232.
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)
0 238 and Lane Keep Assist
(LKA) 0238.

Remote Vehicle Start
This feature allows the engine to be
started from outside the vehicle.
/: This button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a remote
start. The rear window defogger may
come on during remote start based on
cold ambient conditions. The rear
defog indicator light does not come on
during remote start.
If equipped, the heated and ventilated
front seats may also come on when
the vehicle personalization setting is
enabled. See Heated and Ventilated
Front Seats 062.
Laws in some local communities may
restrict the use of remote starters. For
example, some laws may require a
person using remote start to have the
vehicle in view. Check local
regulations for any requirements.
If your vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel.
The RKE transmitter range may be
shorter while the vehicle is running. Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System
029.
Starting the Engine Using Remote
Start
1. Press and release
Qon the RKE
transmitter.
2. Immediately press and hold

SEATS AND RESTRAINTS 79
{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
You can lock the doors, turn off the interior lamps, and turn off the hazard
warning flashers by using the controls
for those features.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
. Airbags are designed to inflate
only once. After an airbag inflates,
you will need some new parts for the airbag system. If you do not
get them, the airbag system will
not be there to help protect you in
another crash. A new system will
include airbag modules and
possibly other parts. The service
manual for the vehicle covers the
need to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
See Vehicle Data Recording and
Privacy 0325 and Event Data
Recorders 0325.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.
