154 UNDERSTANDING THE FEATURES OF YOUR VEHICLE WARNING! Electronic Speed Control can be dangerous where the system cannot maintain a constant speed. Your vehicle could go too fast for the conditions and you could lose control. An accident could be the result. Do not use Electronic Speed Control in heavy traffic or on roads that are winding, icy, snow-covered or slippery. ADAPTIVE CRUISE CONTROL (ACC) - IF EQUIPPED Adaptive Cruise Control (ACC) increases the driving convenience provided by cruise control while traveling on highways and major roadways. However, it is not a safety system and not designed to prevent collisions. ACC will allow you to keep cruise control engaged in light to moderate traffic conditions without the constant need to reset your cruise control. ACC utilizes an infrared sensor designed to detect a vehicle directly ahead of you. NOTE: • If the sensor does not detect a vehicle ahead of you, ACC will maintain a fixed set speed. • If the ACC sensor detects a vehicle ahead, ACC will apply limited braking or acceleration automatically to maintain a preset following distance, while matching the speed of the vehicle ahead.
