Reducing Speed While Using Cruise
Control
If the cruise control system is already engaged,
•
Push and hold the SET button until you reach
the lower speed you want, then release it.
•
To slow down in very small amounts, push the
SET button briefly. Each time you do this,
you'll go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to
step on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control.
Many drivers find this to be too much trouble and don't
use cruise control on steep hills.
Ending Cruise Control
To end cruise control, step lightly on the brake pedal or
the clutch if your vehicle has a manual transmission.
Stepping on the brake pedal or clutch will only end
the current cruise control session. Press the cruise
control on/off button to turn the system completely off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
