232 STARTING AND OPERATING
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
display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have
degraded performance.
The “ACC/FCW Limited Functionality Clean
Fro
nt 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
sho
uld 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
fun
ctionality is no longer present, the system
will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Fro
nt 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 instrument
cluster 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 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 unexpectedly. The driver needs to
stay alert and may need to intervene.
NOTE:
Do not put stickers or easy passes over the
camera/radar field of view.
Cracks in the windshield may affect the
performance of ACC, depending on the size
and location of the crack.
Towing A Trailer
Towing a trailer is not advised when using ACC.
