Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the steepness
of the hills. It may not detect a vehicle in your lane while
driving on hills. When going up steep hills, you may want
to use the accelerator pedal to maintain your vehicle’s
speed. When going downhill, especially when towing a
trailer, you may want to brake to keep your speed down.
Applying the brake disengages the system. You may
choose not to use Adaptive Cruise Control on steep hills,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
Press the Adaptive Cruise Control button or turn
the ignition off.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem with
the Adaptive Cruise Control. See DIC Warnings and
Messages on page 3-73 for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use Adaptive Cruise Control
in icy conditions, or when visibility is low, such as in fog,
rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to
engage the Adaptive Cruise Control. If you are
unable to do so, see your dealer/retailer.
