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:
Installing a snowplow, front-end protector, an aftermarket
grille or modifying the grille is not recommended. Doing so
may block the sensor and inhibit ACC operation.
"CLEAN FRONT WINDSHIELD" WARNING
The "ACC Limited Functionality Clean Front Windshield"
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 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 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 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 WARNING
If the system turns off, and the instrument cluster display
reads "ACC Unavailable Service Required" or "Cruise
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 recommended when using ACC.
STARTING AND OPERATING
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.
NOTE:
On tight turns ACC performance may be limited.
