Cruise Control Your vehicle has cruise control. 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). Cruise control will not work if your parking brake is set, or if the master cylinder brake fluid level is low. {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 excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. If your vehicle is in cruise control, and has the Traction Control System (TCS), and it begins to limit wheel spin, the cruise control automatically disengages. See Traction Control System (TCS) on page 4-6. When road conditions allow you to safely use it again, you can turn cruise control back on. 3-11 9 (Off): Slide the switch to this position to turn the system off. R (On): Slide the switch to this position to turn the system on. + (Resume/Accelerate): Slide the switch to this position to make the vehicle accelerate or resume a previously set speed. T (Set): Press this button at the end of the lever to set the speed.
