SET ACCEL. For
speed control to
operate, the speed
control must be ON
and the vehicle
speed must be

If you drive up or down a steep hill, your vehicle
speed may vary momentarily slower or faster than
the set speed. This is normal.
Speed control cannot reduce the vehicle speed if it
increases above the set speed on a downhill. If your

driving on a downhill, you may want to shift to the
next lower gear or apply the brakes to reduce your
vehicle speed.

(10 mph) below your set speed on an uphill, your
speed control will disengage. This is normal.
