If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
Activation
Push and release the Adaptive Cruise Control
(ACC) on/off button.
“ACC READY” will appear in the instrument
cluster display to indicate the ACC is on.
Setting 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.
If the system is set when the vehicle speed is
below 20 mph (32 km/h), the set speed shall
be defaulted to 20 mph (32 km/h). If the
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:
ACC cannot be set if there is a stationary
vehicle in front of your vehicle in close prox-
imity.
Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this oc-
curs:
The message “DRIVER OVERRIDE” will
appear in the instrument cluster display.
The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be de-
termined by the position of the accelerator
pedal.
Varying The Speed
Once the ACC has been activated, the speed
can be increased or decreased.
NOTE:
When you override and push the SET (+)
button or SET (-) buttons, the new set
speed will be the current speed of the
vehicle.
When you use the SET (-) button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
The ACC system applies the brake down to
a full stop when following a target vehicle.
If an ACC host vehicle follows a target
vehicle to a standstill, the host vehicle will
release the vehicle brakes two seconds af-
ter coming to a full stop.
The ACC system maintains set speed when
driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and nec-
essary to maintain set speed. When driving
up hill and down hill, the ACC system will
cancel if the braking temperature exceeds
normal range (overheated).
To Increase Speed
While ACC is set, you can increase the set
speed by pushing the SET (+) button.
The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
further information. The speed increment
shown is dependant on the chosen speed unit
of U.S. (mph) or Metric (km/h):
