Driver Controls Hilly condition usage It is recommended that the driver select a lower gear position when ACC is active in situations such as prolonged downhill driving on steep grades (i.e., driving in mountainous areas). In these situations, additional engine braking is needed to reduce the load on the vehicle's regular brake system to prevent them from overheating. For more information, reference Automatic transmission operation in the Driving chapter. Note: If ACC is applying brakes for an extended period of time, an audible alarm will sound, the head's up display will flash and ACC will shut down. This is to allow the brakes to cool down. When the brakes have cooled down, the ACC will again function normally. Turning off cruise control Press the OFF button to turn off the cruise control. Note: When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. Detection issues The radar sensor has a limited field of vision. In some situations it may not detect vehicles at all or detect a vehicle later than expected. Detection issues can occur: • When driving on a different line than the vehicle in front. 87 2010 MKS (mks) Owners Guide, 2nd Printing USA (fus)
