Setting Cruise Control

CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push the SETKOAST button at the end of the lever
and release it. The cruise set speed will be displayed
by the Driver Information Center (DIC).
4. Take your foot off the accelerator pedal. The pedal
will return to an "idle" position.
