UNDERSTANDING THE FEATURES OF YOUR VEHICLE 215 Service ACC/FCW Warning If the system turns off, and the EVIC 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 drivable under normal conditions, ACC will be temporarily unavailable. If this occurs, try activating ACC again later, following a key cycle. If the problem persists, see your 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. Towing A Trailer NOTE: 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. 3 Offset Driving Condition Example
