The driver should stay alert and intervene when necessary. ACC not available Several conditions exist which can cause ACC to deactivate or prevent ACC from activating when requested. These conditions include: • The sensor is blocked, refer to Blocked sensor in this section. • Brake temperature is high, refer to Hilly condition usage in this section. • A failure has occurred in the ACC system or related system.
