If the cruise control system is
already activated,
Press and hold the SET button
on the steering wheel until the
desired lower speed is reached,
then release it.
To slow down in small amounts,
press the SET button on the
steering wheel briefly. Each time
this is done, the vehicle goes
about 1.6 km/h (1 mph) slower.
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise speed.
How well the cruise control works
on hills depends on the vehicle
speed, the load, and the steepness
of the hills. When going up steep
hills, pressing the accelerator pedal
may be necessary to maintain
vehicle speed.
While going downhill, the
Cruise Grade Braking feature
may automatically shift to a lower
gear to keep the speed down.
It may be necessary to apply the
brake or manually shift the
transmission to a lower gear. The
vehicle may shift to a higher gear
when grade braking assistance is
no longer required. Cruise Grade
Braking is not available while in
Range Selection Mode. This feature
is active when the exhaust brake is
enabled (if equipped). See "Range
Selection Mode" under
.
When the brakes are manually
applied the cruise control is
disengaged.
There are three ways to end cruise
control:
To disengage cruise control;
step lightly on the brake pedal.
Press
on the steering wheel.
To turn off the cruise control,
press
on the steering wheel.
The cruise control set speed is
erased from memory by pressing
the
button or if the ignition is
turned off.
