Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal is depressed automatically to do this.
Keep in mind that cruise control is a conve-

during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.
