into the sun and fog on the inside of glass. In these
cases, the instrument cluster display will show “ACC/
FCW Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 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
obstruction, have the windshield and forward facing
camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument cluster dis-
plays “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 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.
NOTE:
•
Aftermarket add-ons such as snow plows, lift kits,
and brush/grille bars can hinder module perfor-
mance. Ensure the radar/camera has no obstruc-
tions in the field of view.
•
Height modifications can limit module performance
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.
Cleaning Instructions
Dust and dirt can accumulate on the cover and block
the camera lens. Clean the camera lens with a soft
microfiber cloth, being careful not to damage or scratch
the module.
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 decrease the vehicle speed and acceleration for
stability reasons, with no target vehicle 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.
NOTE:
On tight turns ACC performance may be limited.
