General Information
Warning: Do not use the cruise control system when driving conditions do not permit maintaining a constant speed, such as in heavy traffic or on roads that are winding, icy, snow-covered, slippery, or roads with a loose driving surface. Failure to follow this precaution could cause a collision or loss of vehicle control, possibly resulting in personal injury or property damage.
Note: If the vehicle is equipped with a Detroit multifunction control, setting the cruise control with the engine brake on will activate Descent Control Mode. Moving the lever to the top position will resume the set cruise speed. Moving the lever down to engage the engine brake after the cruise control has been set will activate Deceleration Mode. See "Descent Control and Deceleration Modes, Detroit™ Automated Transmissions" in this chapter.
The cruise control is operated by four buttons mounted in the right-hand switch pod of the steering wheel. See Fig..
