SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster dis-
play 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 temporar-
ily 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 unexpect-
edly. 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.
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.
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 stabil-
ity, 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. The
driver must maintain control of the vehicle, remain
alert, and be ready to apply the brakes if needed.
STARTING AND OPERATING
USING ACC ON HILLS
ACC performance may be limited when driving on hills.
ACC may not detect a vehicle in your lane depending on
the speed, vehicle load, traffic conditions, and the
steepness of the hill.
ACC Hill Example
LANE CHANGING
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the following lane
changing example, ACC has not yet detected the vehicle
changing lanes and it may not detect the vehicle until
it's too late for the ACC system to take action. ACC may
not detect a vehicle until it is completely in the lane.
There may not be sufficient distance to the lane-
changing vehicle. Always be attentive and ready to
apply the brakes if necessary.
