yellowblue Cruise Control (If Equipped) With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). CAUTION: D Cruise control can be dangerous where you can't drive safely at a steady speed. So, don't 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. Don't use cruise control on slippery roads. D If you have an automatic transmission and you apply your brakes, the cruise control will shut off. If you have a manual transmission and you apply your brakes or push the clutch pedal, the cruise control will shut off. 2-38
