2008 Acura RL Owner's Manual - Page 287

Main Menu Table Of Contents Adaptive Cruise Control (ACC) Limitations ACC does not work below 25 mph (40 km/h). It cannot bring your vehicle to a complete stop. ACC will not sound a beeper or display a message on the multiinformation display to warn you of vehicles going slower than 13 mph (20 km/h) or vehicles that are parked. In these cases, it is up to you to maintain a safe distance by using the brake pedal. ACC may not recognize motorcycles or other small vehicles ahead of your vehicle. ACC may react to vehicles beside you or even building beside you by momentarily applying the brakes or sounding a beeper under conditions such as a sudden curve or narrowing of the road, an abrupt movement of the steering wheel, or if you are in an unusual position within your lane. 284 2008 RL
