STARTING AND OPERATING 245
“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 driv-
able under normal conditions, ACC will be
temporarily unavailable. If this occurs, try acti-
vating 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.
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.
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 decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle 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 func-
tionality.
NOTE:
On tight turns ACC performance may be limited.
