Caution: Do not use the cruise control on slippery roads, steeply graded roads, or in heavy traffic of heavy or varying volume. Failure to follow these CAUTIONS could possibly cause you to loose control of the vehicle and result in damage to the vehicle and personal injury.

Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions. Steep grades, up or down, may cause variations in the selected speeds. The cruise control system controls the following functions:

    • Cruise
    • Resume speed
    • Accelerate
    • Tap-up
    • Tap-down

Refer to the following list for the main components of the cruise control system:

    • The turn signal and multi-function switch
    • The cruise control module
    • The cruise control cable
    • The vehicle speed sensor
    • The cruise control release switch
    • The stoplamp switch

The cruise control release switch and the stoplamp switch disengage the cruise system. The switches are mounted on the brake pedal bracket. When the brake pedal is depressed, the following actions occur:

    • The switches electrically disengage the cruise control system.
    • The throttle returns to the idle position.
