1. Push in the button at the end of the lever until you reach the lower
speed you want, then release it.
2. To slow down in very small amounts, push the button for less than half
a second. Each time you do this, you'll go 1 mph (1.6 kmlh) 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.
