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.
To Get Out of Cruise Control
There are two ways to turn off the Cruise Control:
0
Step lightly on
the brake pedal or
push the clutch
pedal, if you have
a manual
transmission
OR;
0
move the Cruise
switch to
OFF.
To Erase Speed Memory
When you turn off the Cruise Control or the ignition, your Cruise Control
set speed memory is erased.
