114 STARTING AND OPERATING
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 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 an authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument
cluster display 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 temporarily 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 unexpectedly. The driver needs to
stay alert and may need to intervene. The
following are examples of these types of
situations:
Towing A Trailer
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
Turns And Bends
When driving on a curve with ACC engaged, the
system may increase or decrease the vehicle
speed for stability, 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.
