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 EVIC/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
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.

•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 EVIC/DID
will display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have degraded
performance.
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.
When the condition that created limited functionality is
no longer present, the system will return to full function-
ality.
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/DID 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 tempo-
rarily 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.
Offset Driving Condition Example
210 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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).
To change between the different control modes, press the
ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the NORMAL (Fixed Speed)
ELECTRONIC SPEED CONTROL OFF. Pressing of the
NORMAL (Fixed Speed) ELECTRONIC SPEED CON-
TROL ON/OFF button will result in turning ON (chang-
ing to) the Normal (Fixed Speed) Electronic Speed Con-
trol mode.
WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
neither the presence of the vehicle ahead nor the
vehicle-to vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Electronic
Speed Control ON. When the vehicle has
reached the desired speed, press the SET (+) or
SET (-) button and release. Release the accel-
erator and the vehicle will operate at the selected speed.

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/DID), 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.
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
progressive 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
218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 braking possible to mitigate
the potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle com-
pletely, the system will hold the vehicle at standstill for
two seconds and then release the brakes.
When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.
FCW Message

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 219

NOTE:
•The minimum speed for FCW activation is 1 mph
(2 km/h).
•The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
•It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within a key cycle, the Active Braking portion of FCW
will be deactivated until the next key cycle.
•The FCW system is intended for on-road use only. If
the vehicle is taken off-road, the FCW system should
be deactivated to prevent unnecessary warnings to the
surroundings.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect
every type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.
Turning FCW ON Or OFF
NOTE:The default status of FCW is “On”, this allows
the system to warn you of a possible collision with the
vehicle in front of you.
The forward collision button is located on the switch
panel below the Uconnect® display.
220 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
