Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the

previous set cruise speed.
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 keep the
speed down.
.
Vehicles with a six speed
automatic transmission have a
Cruise Grade Braking feature
that 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
Manual Mode on page 9‑41.

applied the cruise control is
disengaged.
