Before Driving Your Mazda Driving Tips Rocking the Vehicle WARNING Do not spin the wheels at more than 56 km/h (35 mph), and do not allow anyone to stand behind a wheel when pushing the vehicle: When the vehicle is stuck, spinning the wheels at high speed is dangerous. The spinning tire could overheat and explode. This could cause serious injuries. l Winter Driving Carry emergency gear, including tire chains, window scraper, flares, a small shovel, jumper cables, and a small bag of sand or salt. Ask an Authorized Mazda Dealer to perform the following precautions: l Have the proper ratio of antifreeze in the radiator. Refer to Engine Coolant on page 8-21. l Inspect the battery and its cables. Cold reduces battery capacity. l Inspect the ignition system for damage and loose connections. l Use washer fluid made with antifreeze―but don't use engine coolant antifreeze for washer fluid (page 8-26). l Don't use the parking brake in freezing weather as the parking brake may freeze. Instead, shift to P and block the rear wheels. CAUTION Too much rocking may cause engine overheating, transaxle failure, and tire damage. If you must rock the vehicle to free it from snow, sand or mud, depress the accelerator slightly and slowly move the shift lever from D to R. qSnow Tires Use snow tires on all four wheels Don't go faster than 120 km/h (75 mph) while driving with snow tires. Inflate snow tires 30 kPa (0.3 kgf/cm2, 4.3 psi) more than recommended on the tire pressure label (driver's door frame), but never more than the maximum cold-tire pressure shown on the tires. WARNING Use only the same size and type tires (snow, radial, or non-radial) on all four wheels: Using tires different in size or type is dangerous. Your vehicle's handling could be greatly affected and result in an accident. 4-9
