NOTE:
•The Rain Sensing feature will not operate when the
wiper speed is in the low or high position.
•The Rain Sensing feature may not function properly
when ice or dried salt water is present on the wind-
shield.
•Use of Rain-X® or products containing wax or silicone
may reduce rain sensor performance.
The Rain Sensing system has protective features for the
wiper blades and arms. It will not operate under the
following conditions:
•Low Temperature Wipe Inhibit— The Rain Sensing
feature will not operate when the ignition is placed in
the RUN position, the vehicle is stationary and the
outside temperature is below 32°F (0°C), unless the
wiper control on the multifunction lever is moved, the
vehicle speed becomes greater than 0 mph (0 km/h) or
the outside temperature rises above freezing.
•Neutral Wipe Inhibit— The Rain Sensing feature will
not operate when the ignition is placed in the RUN
position, the automatic transmission gear selector is in
the NEUTRAL position and the vehicle speed is less
than 3 mph (5 km/h), unless the wiper control on the
multifunction lever is moved or the gear selector is
moved out of the NEUTRAL position.
•Remote Start Mode Inhibit— On vehicles equipped
with Remote Starting system, Rain Sensing wipers are
not operational when the vehicle is in the remote start
mode. Once the operator is in the vehicle and has
placed the ignition switch in the ON/RUN position,
rain sensing wiper operation can resume, if it has been
selected, and no other inhibit conditions (mentioned
previously) exist.

ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor and a forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.
The Cruise Control system has two control modes:
•Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
•Normal (fixed speed) electronic speed control mode
for cruising at a constant preset speed. For additional
information, refer to “Normal (Fixed Speed) Cruise
Control Mode” in this section.
NOTE:Normal (fixed speed) electronic speed control
will not react to preceding vehicles. Always be aware of
the mode selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently.
Always confirm which mode is selected.

To decrease the distance setting, push the Distance Set-
ting — Decrease button and release. Each time the button
is pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the DID displays the “Sensed Vehicle Indica-
tor” icon, and the system adjusts vehicle speed automati-
cally to maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
•The vehicle ahead moves out of your lane or view of
the sensor.
•The distance setting is changed.
•The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the DID and a chime will sound
while ACC continues to apply its maximum braking
capacity.

When ACC is set, the set speed will display in the
instrument cluster.
The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
•System Cancel
•Driver Override
•System Off
•ACC Proximity Warning
•ACC Unavailable Warning
•The DID will return to the last display selected after
five seconds of no ACC display activity
Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud,
dirt or ice. In these cases, the DID will display “ACC/
FCW Unavailable Wipe Front Radar Sensor” and the
system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after the
188 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
•Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to damage
the sensor lens.
•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
•If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
•Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.

NOTE:
•If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstruction, have the radar sensor realigned at
your authorized dealer.
•Installing a snow plow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and also a chime will
indicate when conditions temporarily limit system per-
formance. This most often occurs at times of poor visibil-
ity, such as in snow or heavy rain and fog. The ACC
system may also become temporarily blinded due to
obstructions, such as mud, dirt, or ice on windshield and
fog on the inside of glass. In these cases, the DID will
display “ACC/FCW Limited Functionality Clean Front
Windshield” and the system will have degraded perfor-
mance.
The “ACC/FCW Limited Functionality Clean Front
Windshield” message can sometimes be displayed while
driving in adverse weather conditions. The ACC/FCW
system will recover after the vehicle has left these areas.
Under rare conditions, when the camera is not tracking
any vehicles or objects in its path this warning may
temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may
require cleaning or removal of an obstruction.

NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning. If
the driver does not take action based upon these progres-
sive warnings, then the system will provide a limited
level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by
braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required. If a Forward Collision Warning with
Mitigation event begins at a speed below 20 mph
(32 km/h), the system may provide the maximum or
partial braking to mitigate the potential forward colli-
sion. If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will hold
the vehicle at standstill for two seconds and then release
the brakes.

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 approxi-
mately 7 mph (11 km/h) or above. The system will
become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
ParkSense® Sensors
The four ParkSense® sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
The six ParkSense® sensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 in (30 cm) up to 47 in
(120 cm) from the front fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSense® Warning Display
The ParkSense® Warning screen will only be displayed if
Sound and Display is selected from the Customer -
Programmable Features section of the Uconnect® Sys-
tem. Refer to#Uconnect® Settings” in “Understanding
Your Instrument Panel” for further information.
The ParkSense® Warning screen is located within the
Driver Information Display (DID). It provides visual
warnings to indicate the distance between the rear
fascia/bumper and/or front fascia/bumper and the de-
tected obstacle. Refer to “Driver Information Display
(DID)” for further information.
