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 Sen-
sor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstructions, have the radar sensor realigned
at an authorized dealer.
•
Installing a snowplow, 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 Wind-
shield” warning will display, and a chime will sound
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, 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 instrument cluster
display will read “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have degraded
performance.
This 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 tempo-
rarily 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 rearview 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
functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front Wind-
shield” message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstructions, have the windshield and forward facing
camera inspected at an authorized dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster dis-
play reads “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 temporar-
ily 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
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.
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 merg-
ing in from a side lane. There may not be sufficient dis-
tance 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.
TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may increase or decrease the vehicle speed for stabil-
ity, with no vehicle ahead detected. Once the vehicle is
out of the curve, the system will resume your original
set speed. This is a part of normal ACC system
functionality.
