To Vary The Speed Setting

To Increase Speed
While ACC is set, you can increase the set
speed by pushing the SET (+) button.
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.
If the button is continually pushed, the set

speed will continue to increase in 10 km/h
increments until the button is released. The
increase in set speed is reflected in the
instrument cluster display.

To Decrease Speed
While ACC is set, the set speed can be
decreased by pushing the SET (-) button.
The speed decrement 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 decrease in set speed. Each subse-
quent tap of the button results in a decrease
of 1 mph.
If the button is continually pushed, the set

speed will continue to decrease in 5 mph
increments until the button is released. The
decrease 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 decrease in set speed. Each subse-
quent tap of the button results in a decrease
of 1 km/h.
If the button is continually pushed, the set

speed will continue to decrease in 10 km/h
increments until the button is released. The
decrease in set speed is reflected in the
instrument cluster display.
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 automatically
slow the vehicle.
The ACC system decelerates the vehicle to a

full stop when following a target vehicle. If
an ACC host vehicle follows a target vehicle
to a standstill, after two seconds the driver
will either have to push the RES (resume)
button, or apply the accelerator pedal to
reengage the ACC to the existing set speed.
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 occur
while climbing uphill or descending down-
hill. This is normal operation and necessary
to maintain set speed. When driving up hill
and down hill, the ACC system will cancel if
the braking temperature exceeds normal
range (overheated).
