Operation Winter driving If applicable to your vehicle's tire configuration, tires can be rotated according to the tire manufacturer's recommended intervals in the tire manufacturer's warranty pamphlet located in your vehicle literature portfolio. If none is available, tires should be rotated every 3 000 to 6 000 miles (5 000 to 10 000 km), or sooner if necessary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained. Rotate tires before the characteristic tire wear pattern becomes visible (shoulder wear on front tires and tread center wear on rear tires). Thoroughly clean the mounting face of wheels and brake disks, i.e. the inner side of the wheels/tires, during each rotation. Check for and ensure proper tire inflation pressure. For information on wheel change, see "Flat tire" (Y page 547). sure the tires you use show the mountain/ snowflake.marking on the tire sidewall. These tires meet specific snow traction performance requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) and have been designed specifically for use in snow conditions. Use of winter tires is the only way to achieve the maximum effectiveness of your vehicle's driving safety systems such as the ABS and the ESP® in winter operation. For safe handling, make sure all mounted winter tires are of the same make and have the same tread design. For information on winter tires for your vehicle model, see the "Technical data" section (Y page 569). Always observe the speed rating of the winter tires installed on your vehicle. If the maximum speed for which your tires are rated is below the speed rating of your vehicle, you must place a notice to this effect where it will be seen by the driver. Such notices are available at your tire dealer or any authorized Mercedes-Benz Center. Winter driving General information Have your vehicle winterized at an authorized Mercedes-Benz Center. Winter tires G Warning! Winter tires with a tread depth of less than 1/ in (4 mm) must be replaced. They are 6 no longer suitable for winter operation. G Warning! If you use your spare wheel when winter tires are fitted on the other wheels, be aware that the difference in tire characteristics may very well impair turning stability and that overall driving stability may be reduced. Adapt your driving style accordingly. Have the spare wheel replaced by regular road wheel with a winter tire at the nearest authorized Mercedes-Benz Center. Always use winter tires at temperatures below 45‡ (7†) and whenever wintry road conditions prevail. Not all M+S rated tires provide special winter performance. Make 452
