Using Cruise Control on Hills
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:
.
Vehicles with a four speed
automatic transmission may
need to have the brakes applied
or the transmission shifted to a
lower gear to help maintain
driver selected speed.
.
Vehicles with a six speed
automatic transmission have
Cruise Grade Braking to help
maintain driver selected speed.
Cruise Grade Braking is enabled
when the vehicle is started and
Cruise Control is active. It is not
enabled in Range Selection Mode.
It assists in maintaining driver
selected speed when driving on
downhill grades by using the engine
and transmission to slow the
vehicle.
To disable and enable Cruise Grade
Braking for the current ignition key
cycle, press and hold the Tow/Haul
button for three seconds. A DIC
message displays. See
Transmission Messages on
page 5‑37.
When the brakes are manually
applied the cruise control is
disengaged.
Ending Cruise Control
There are three ways to end cruise
control:
.
To disengage cruise control,
step lightly on the brake pedal.
.
Press the [ on the steering
wheel.
.
To turn off the cruise control,
press
I on the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
I is
pressed or if the vehicle is
