186 STARTING AND OPERATING
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe
the sensor lens with a soft cloth. Be cautious
not to damage the sensor lens.
Do not use solvents or abrasive pastes. The
radar is equipped with a defrost system, so in
some climatic conditions it could reach high
temperatures. Wait at least 30 seconds after
the engine has been placed in the OFF mode
before touching the sensor.
Do not remove any screws from the sensor.
Doing so could cause an ACC system
malfunction or failure and require a sensor
realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see your autho-
rized dealer for service.
Do not attach or install any accessories near
the sensor, including transparent material.
Doing so could cause an ACC system failure
or malfunction.
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 when reactivated.
NOTE:
If the “ACC Front Radar Sensor Temporarily
Blocked” message occurs frequently (e.g.
more than once on every trip) without any
snow, rain, mud, or other obstruction, have
the radar sensor realigned at your authorized
dealer.
Installing a snow plow or front-end protector
is not recommended. Doing so may block the
sensor and inhibit ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Wipe Front
Windshield” warning will display to indicate
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 Wipe Front Windshield” and the
system will have degraded performance.
The “ACC/FCW Limited Functionality Wipe 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 functionality.
NOTE:
If the “ACC/FCW Limited Functionality Wipe
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.
