Reducing Speed While Using
Cruise Control
•
Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
•
To slow down in very small amounts, briefly press
the set button. 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 want 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
There are four ways to turn off the cruise control:
•
Step lightly on the brake pedal,
•
move the cruise control switch to off, or
•
shift the transmission to NEUTRAL (N).
•
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
