Using Cruise Control on Hills How well the cruise control works on hills depends upon the vehicle's speed, load, and the steepness of the hills. When going up steep hills, you might want to step on the accelerator pedal to maintain the vehicle's speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle's speed down. When the brakes are applied the cruise control turns off. • If driving in hilly terrain, cruise control may not be able to maintain vehicle speed if an up-shift or down-shift is not selected by the driver. While driving on hilly terrain and cruise control is active with a manual paddle shift gear selection, the driver must select the proper gear for the terrain or select D (Drive) on the gear range selector for full automatic transmission operation. Cruise Control in Sport and Manual Paddle Shift Gear Selection When the vehicle is in S (Sport) and the manual paddle shift controls are not being used, cruise control operates in the same manner as D (Drive). When the vehicle is in S (Sport) and the manual paddle shift controls are being used, cruise control operates as follows: Ending Cruise Control To end a cruise control session, step lightly on the brake pedal. If the vehicle has a manual transmission, lightly tapping the clutch will also end a cruise control session.

When cruise control is disengaged, the CRUISE DISENGAGED message displays on the Driver Information Center (DIC). See DIC Warnings and Messages on page 4-51.
