Highway Exit Ramps Using Adaptive Cruise Controls on Hills { CAUTION: Adaptive Cruise Control may lose track of the vehicle ahead and accelerate up to your set speed while entering or on highway exit ramps. You could be startled by this acceleration and even lose control of the vehicle. Disengage Adaptive Cruise Control before entering a highway exit ramp. Do not use Adaptive Cruise Control while entering or on exit ramps. Other Vehicle Lane Changes How well Adaptive Cruise Control works on hills depends on your speed, vehicle load, traffic conditions, and the steepness of the hills. It might not detect a vehicle in your lane while driving on hills. While going up steep hills, you might want to use the accelerator pedal to maintain your vehicle speed. While going downhill, you might have to brake to keep your vehicle speed down. Applying the brake disengages the system. You may choose not to use Adaptive Cruise Control on steep hills. Disengaging Adaptive Cruise Control Apply the brake pedal or move the Adaptive Cruise Control switch to off, to disengage the system. Adaptive Cruise Control information does not appear on the HUD while the system is not engaged. If another vehicle enters the same lane as you, Adaptive Cruise Control will not detect the vehicle until it is completely in the lane. Be ready to take action and apply the brakes yourself. 3-24
