When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the EVIC 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 a
key cycle. If the problem persists, see your authorized
dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Towing A Trailer
NOTE: Towing a trailer is not advised when using ACC.
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.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and
it may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until
it is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be atten-
tive and ready to apply the brakes if necessary.

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.

Normal (Fixed Speed) Electronic Speed
Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be
operated if the vehicle speed is above 20 mph (32 km/h).

•If the button is continually pressed, the set speed will
continue to decrease in 5 mph increments until the
button is released. The decrease in set speed is re-
flected in the EVIC display.
Metric Speed (km/h)
• Pressing the SET -button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
• If the button is continually pressed, the set speed will
continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is re-
flected in the EVIC display.To Cancel
The following conditions will cancel the Normal (Fixed
Speed) Electronic Speed Control without clearing the
memory:
• The brake pedal is applied.
• The CANCEL button is pressed.
• The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
• The vehicle parking brake is applied.
• The braking temperature exceeds normal range (over-
heated).
• The shift lever/gear selector is removed from the
Drive position.

To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
To Turn Off
The system will turn off and erase the set speed in
memory if:
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pressed.
• The ignition is turned off.
• You engage Four-Wheel Drive Low.
• The Adaptive Cruise Control (ACC) On/Off button is
pressed.
FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC), and may apply a
brake jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
216 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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. When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.

To turn the FCW system OFF, press the forward collision
button once to turn the system OFF (led turns on).
To turn the FCW system back ON, press the forward
collision button again to turn the system ON (led turns
off).•
Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the
vehicle in front of you.
• Changing the FCW sensitivity - Near vs. Far. Far warns
the driver of a possible collision earlier and Near
warns the driver later.
• Changing the Active Braking status to “Off” prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
NOTE: The FCW system state is kept in memory from
one key cycle to the next. If the system is turned OFF,
it will remain off when the vehicle is restarted.

Changing LaneSense Status
The LaneSense system has settings that you can config-
ure the intensity of the torque warning and the warning
zone sensitivity (early/late) through the Uconnect® sys-
tem screen. Refer to “Uconnect® Settings” in “Under-
standing Your Instrument Panel” for further information.
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.).
PARKSENSE® REAR PARK ASSIST —
IF EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense® System
Usage Precautions for limitations of this system and
recommendations.
ParkSense® will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense® can be active only when the shift lever/gear
selector is in REVERSE. If ParkSense® is enabled at this
shift lever/gear selector position, the system will remain
active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. When in REVERSE
