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” willappear 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): U.S. Speed (mph)
• Pushing the SET
(+)button once will result
in a 1 mph increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph.
• If the button is continually pushed, the set speed will continue to increase in 5 mph
increments until the button is released.
The increase in set speed is reflected in the
instrument cluster display.
Metric Speed (km/h)
• Pushing the SET (+)button once will result
in a 1 km/h increase in set speed. Each
subsequent tap of the button results in an
increase of 1 km/h.
