and rapidly beeps or pulses the driver
seat. FPB can provide a boost to
braking or automatically brake the
vehicle.
SeeFront Pedestrian Braking (FPB)
System 0264.
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)
0 270 and Lane Keep Assist (LKA)
0 271.
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) 0268
and Lane Change Alert (LCA) 0269.
Surround Vision
If equipped, views around the vehicle
display in the infotainment display to
aid with parking and low-speed
maneuvers.
See “Surround Vision ”under
Assistance Systems for Parking or
Backing 0254. Front Vision Camera
If equipped, a view of the area in front
of the vehicle displays on the
infotainment display to aid with
parking and low-speed maneuvers.
See
“Front Vision Camera ”under
Assistance Systems for Parking or
Backing 0254.
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 0254.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system uses a
triangle with an arrow displayed 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.

24 IN BRIEF
SeeAssistance Systems for Parking or
Backing 0254.
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.
See Assistance Systems for Parking or
Backing 0254.
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, displays, and beeps. When the vehicle
speed is below 30 km/h (18 mph),
touch
Oto enable the system.
See “Automatic Parking Assist (APA)”
under Assistance Systems for Parking
or Backing 0254.
Reverse Automatic
Braking (RAB)
If the vehicle has Adaptive Cruise
Control (ACC) it also has the RAB
system, which is designed to help
avoid or reduce the harm caused by
backing crashes when the vehicle is
shifted into R (Reverse). If the system
detects the vehicle is backing too fast
to avoid a crash with a detected object
behind your vehicle in your path, it
may automatically brake hard to
a stop.
See Assistance Systems for Parking or
Backing 0254.
Surround Vision Recorder
If equipped, the Surround Vision
Recorder records 360° camera views to
an SD card. Only images are recorded,
no sound. See
Surround Vision Recorder 0272.
Power Outlets
Power Outlet 12-Volt Direct
Current
The 12-volt accessory power outlet
can be used to plug in electrical
equipment, such as a cell phone or
MP3 player. The vehicle may have an
accessory power outlet on the rear
seat trim panel (gasoline and
PLUG-IN) and inside the trunk
(PLUG-IN only).

144 INSTRUMENTS AND CONTROLS
If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0288. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Fuel0286.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0295.
See your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The light is on when the engine is
running.
. The light does not come on when
the ignition is in Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
