4-14 Driving Your Vehicle Blizzard Conditions Being stuck in snow can be in a serious situation. Stay with the vehicle unless there is help nearby. If possible, use the Roadside Assistance Program on page 7-6. To get help and keep everyone in the vehicle safe: The StabiliTrak® System on page 4-5 improves the ability to accelerate on slippery roads, but slow down and adjust your driving to the road conditions. When driving through deep snow, turn off the traction control part of the StabiliTrak® System to help maintain vehicle motion at lower speeds. The Antilock Brake System (ABS) on page 4-4 improves vehicle stability during hard stops on a slippery roads, but apply the brakes sooner than when on dry pavement. Allow greater following distance on any slippery road and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice. Turn off cruise control, if equipped, on slippery surfaces. CAUTION (Continued) • Turn on the Hazard Warning Flashers on page 3-5. • Tie a red cloth to an outside mirror. { CAUTION Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. (Continued) If the vehicle is stuck in the snow: • Clear away snow from around the base of your vehicle, especially any that is blocking the exhaust pipe. • Check again from time to time to be sure snow does not collect there. • Open a window about two inches (5 cm) on the side of the vehicle that is away from the wind to bring in fresh air. • Fully open the air outlets on or under the instrument panel. • Adjust the Climate Control system to a setting that circulates the air inside the vehicle and set the fan speed to the highest setting. See Climate Control System in the Index. (Continued)
