Using Adaptive Cruise Controls on Hills
and When Towing a Trailer
How well Adaptive Cruise Control works on hills
and while a trailer is being towed depends on your
vehicle 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
and towing a trailer, you might want 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 when
towing a trailer.
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.
Erasing Set Speed Memory
When the Adaptive Cruise Control switch or the ignition
is turned off, the set speed memory is erased.
Other Messages
There are three 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 3-80 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
emblem/lens, located in the center of the front outside
grille. Remember, do not use Adaptive Cruise Control in
icy conditions, or when visibility is low, such as in fog,
rain or snow.
To clean the emblem/lens, wipe the surface with a soft
cloth. After cleaning the emblem/lens, engage the
Adaptive Cruise Control. If you are unable to do so,
see your dealer/retailer.
