144 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
Using Electronic Speed Control on Hills
NOTE: The Electronic Speed Control system maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
The automatic transmission will downshift while climb-
ing uphill or descending downhill. This downshift is
necessary to maintain vehicle set speed.
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. An accident could be the result.
Do not use Electronic Speed Control in heavy traffic
or on roads that are winding, icy, snow-covered or
slippery.
