To decrease speed while the Electronic Speed Control is
set, push the SET (-) button. If the button is continually
held in the SET (-) position, the set speed will continue to
decrease until the button is released. Release the button
when the desired speed is reached, and the new set speed
will be established.
Pressing the SET (-) button once will result in a 1 mph
(1.6 km/h) decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 mph (1.6 km/h).
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
