Reducing Speed While Using
Cruise Control
There are two ways to reduce the vehicle's speed while
using cruise control:
•
Push in the SET button until the vehicle slows down
to the desired, then release it.
•
To slow the vehicle down in very small amounts,
push the SET button briefly. Each time this is down,
the vehicle will go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle's
speed. When you take your foot off the pedal, the
vehicle will slow down to the cruise control speed that
was set earlier.
3-12
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the speed and load of the vehicle, and the
steepness of the hills. When going up steep hills, the
accelerator pedal may have to be pressed to maintain
the vehicle's speed. When going downhill, the vehicle's
brakes may have to be used, or a lower gear may
have to be used to keep the vehicle's speed down.
Of course, applying the brake takes the vehicle out of
cruise control. Many drivers find this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
•
Step lightly on the brake pedal.
•
Move the cruise switch to OFF.
Ending Speed Memory
When the cruise control or the ignition is turned off, or
the vehicle is shifted into PARK (P) or NEUTRAL (N),
the cruise control set speed memory is erased.
