Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
•
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You'll now cruise at the higher speed.
•
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briefly to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
There are two ways to reduce your 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 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. Applying the
brake or shifting into a lower gear will take you out
of cruise control. If you need to apply the brake or shift
to a lower gear due to the grade of the downhill
slope, you may not want to attempt to use your cruise
control feature.
