Using Cruise. Control on HMs.
How well your cruise control will work
on hills depends upon y~ur 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 zt lower gear to keep your speed
down. Of course, applying the brake or
dutch pedal takes you out of cruise
control.
Many drivers find this to be too
much trouble and don't use cruise
control
on steep hills.
Ti Get Out of Cruk Control
There are several ways to turn off the
cruise control:
Step lightly on the brake pedal or
push
the clutch pedal, if you have a
manual transmission; OR
Move the cruise switch to OFF; OR
* When the ASR systern.is4 activated, it
will turn off the cruise control. For
information about the ASR system,
see the lndex under Accekatiotz Slip
Regulation (ASR) System.
To Erase Cruise Speed Memory
When you turn off the cruise control or
*the ignition, your cruise control set
speed memory is erased.
