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

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.

0 mph (32 km/h), the set speed will default to
20 mp
h (32 km/h).
NOTE:
Fixed Speed Cruise Control cannot be set below
20
mp
h (32 km/h).
If either system is set when the vehicle speed is
above
20 mph (32 km/h), the set speed shall be

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
be controlling the distance between your vehicle
