STARTING AND OPERATING175
Service ACC/FCW Warning

If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service
Required” or “Cruise/FCW Unavailable Service
Required”, there may be an internal system fault
or a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable
under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC
again later, following an ignition cycle. If the
problem persists, see an authorized dealer.

Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has
no obstructions in the field of view.
Height modifications can limit module perfor -
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
In certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs
to stay alert and may need to intervene.
The following are examples of these types of
situations:
Towing A Trailer
ACC while towing a trailer is recommended only
with an Integrated Trailer Brake Controller.
Aftermarket trailer brake controllers will not
activate the trailer brakes when ACC is braking. Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

STARTING AND OPERATING177
Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.

Narrow Vehicle Example
Stationary Objects And Vehicles

ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not react
in situations where the vehicle you are following
exits your lane and the vehicle ahead is stopped in
your lane. Always be attentive and ready to apply the
brakes if necessary

Stationary Object And Stationary Vehicle Example
PARKSENSE FRONT/REAR PARK ASSIST —
IF EQUIPPED

The ParkSense Park Assist system provides visual
and audible indications of the distance between the
rear, and/or front fascia/bumper, and a detected
obstacle when backing up or moving forward (e.g.
during a parking maneuver). For limitations of this
system and recommendations, see
Ú
page 182.

ParkSense will retain the system state (enabled
or disabled) from the previous ignition cycle
when the ignition is placed in the ON/RUN
position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the
instrument cluster display when the vehicle is
in REVERSE, indicating the vehicle is above
ParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).

182STARTING AND OPERATING
SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the Front/Rear
ParkSense System has detected a faulted
condition, the instrument cluster display will
show the "Front/Rear ParkSense Unavailable
Service Required" or the "Front/Rear
ParkSense Unavailable Wipe Sensors"
message.
When the gear selector is moved into REVERSE,
a vehicle graphic will show in the instrument
cluster display, along with the display overlay
“Wipe Sensors.” If the system needs service,
the display overlay will read “Service.” Under
this condition, ParkSense will not operate.
If "Front/Rear ParkSense Unavailable Wipe
Sensors" appears in the instrument cluster
display make sure the outer surface and the
underside of the rear fascia/bumper is clean
and clear of snow, ice, mud, dirt or other
obstruction, and then cycle the ignition. If the
message continues to appear, see an
authorized dealer. If "Front/Rear ParkSense Unavailable Service
Required" appears in the instrument cluster
display, see an authorized dealer.CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car
wash soap and a soft cloth. Do not use rough or
hard cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear bumpers are
free of snow, ice, mud, dirt and debris to keep
the ParkSense system operating properly.

Jackhammers, large trucks, and other vibrations
could affect the performance of ParkSense.
When you move the gear selector to the
REVERSE position and Front or Rear ParkSense
is turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs. This
vehicle graphic will be displayed for as long as
the vehicle is in REVERSE.

ParkSense, when on, will reduce the volume
of the radio when it is sounding a tone.
Clean the ParkSense sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to do
so can result in the system not working prop -
erly. The ParkSense system might not detect
an obstacle behind or in front of the fascia/
bumper, or it could provide a false indication
that an obstacle is behind or in front of the
fascia/bumper.
Use the ParkSense switch to turn the Park -
Sense system off if obstacles such as bicycle
carriers, trailer hitches, etc. are placed within
18 inches (45 cm) from the rear fascia/
bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a
sensor problem, causing the “Front/Rear
ParkSense Unavailable Service Required”
message to be appear in the instrument
cluster display.

184STARTING AND OPERATING
TURNING LANESENSE ON OR OFF
The LaneSense button is located on
the switch panel below the Uconnect
display.
NOTE:
If your vehicle is equipped with a 12–inch
Uconnect Display screen, the LaneSense button
is located above the display.

LaneSense button again (LED turns on).
NOTE:
The LaneSense system will retain the last
system state (on or off) from the last ignition
cycle when the ignition is changed to the
ON/RUN position.
LANESENSE WARNING MESSAGE
The LaneSense system will indicate the current
lane drift condition through the instrument
cluster display.
When the LaneSense system is on, the lane
lines are gray when both of the lane boundaries
have not been detected and the LaneSense
telltale is solid white.

System ON (Gray Lines) With White Telltale
Left Lane Departure — Only Left Lane Detected

When the LaneSense system is on, the Lane -
Sense Telltale is solid white when only the
left lane marking has been detected and the
system is ready to provide visual warnings in
the instrument cluster display if an uninten -
tional lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the visual warning in the
instrument cluster display will show the left
lane line flashing yellow (on/off). The Lane -
Sense telltale changes from solid white to
flashing yellow.

Lane Crossed (Flashing Yellow Lane Line) With Yellow Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure when only
the right lane marking has been detected.

186STARTING AND OPERATING
CHANGING LANESENSE STATUS
The LaneSense system has settings to adjust
the intensity (Low/Medium/High) of the torque
warning and the warning zone sensitivity (Early/
Medium/Late) that you can configure through
the Uconnect system Úpage 228.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph (180 km/h).

Use of the turn signal suppresses the warnings.

The system will not apply torque to the
steering wheel whenever a safety system
engages (Anti-Lock Brakes, Traction Control
System, Electronic Stability Control, Forward
Collision Warning, etc.).
PARKVIEW REAR BACK UP CAMERA
