Cruise Control With cruise control, you can maintain a speed of approximately 25 mph (40 km/h) or more without keeping your foot on the accelerator. This is helpful on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). When cruise control is on, you will see a cruise light on the instrument panel cluster. When you apply your brakes, the cruise control shuts off. If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control System (TCS) on page 4-9. When road conditions allow you to safely use it again, you may turn the cruise control back on. Setting Cruise Control {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. 3-16
