WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always leave
the system off when you are not using it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the
SET (+) button or the SET (-) button and release. The
instrument cluster display will show the set speed.
NOTE:
Fixed Speed Cruise Control can be used without ACC
enabled. To change between the different modes, push
the ACC on/off button which turns the ACC and the Fixed
Speed Cruise Control off. Pushing the Fixed Speed Cruise
Control on/off button will result in turning on (changing to)
Fixed Speed Cruise Control mode.
WARNING!
In Fixed Speed Cruise Control mode, the system will not
react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound even
if you are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and the
vehicle ahead. Always be aware which mode is
selected.
If ACC is set when the vehicle speed is below 20 mph
(32 km/h), the set speed will default to 20 mph
(32 km/h).
NOTE:
Fixed Speed Cruise Control cannot be set below 20 mph
(32 km/h).
If either system is set when the vehicle speed is above
20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
 Keeping your foot on the accelerator pedal can cause
the vehicle to continue to accelerate beyond the set
speed. If this occurs, the message "ACC DRIVER
OVERRIDE" will display in the instrument cluster
display.
 If you continue to accelerate beyond the set speed
while ACC is enabled, the system will not control the
distance between your vehicle and the vehicle ahead.
The vehicle speed will only be determined by the posi-
tion of the accelerator pedal.

memory if:
 The Adaptive Cruise Control (ACC) on/off button is
pushed
 The Fixed Speed Cruise Control on/off button is pushed
 The ignition is placed in the OFF position
 4WD Low is engaged

button and then remove your foot from the accelerator
pedal. The instrument cluster display will show the last set
speed.

(32 km/h) when only Fixed Speed Cruise Control is being
used.
