Operation Winter driving Snow chains Please observe the following guidelines when using snow chains: Use of snow chains is not permissible with all wheel/tire combinations ( page 449). Use snow chains in pairs and on rear wheels only. Follow the manufacturer's mounting instructions. Use of snow chains may be prohibited depending on location. Always check local and state laws before installing snow chains. Do not use snow chains on the spare wheel ( page 453). Do not use snow chains on wheels with MOExtended tires* ( page 449). ! When driving with snow chains, always select setting 1 of the vehicle level control system ( page 230). Other settings may result in damage to your vehicle. ! Some tire sizes do not leave adequate clearance for snow chains. To help avoid serious damage to your vehicle or tires, make sure that the use of snow chains is permissible as specified in the "Technical data" section of this Operator's Manual, see "Rims and tires" ( page 449). Snow chains should only be driven on snow-covered roads at speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow. ! If snow chains are mounted to the front wheels, they may scrape against the body or axle components. The tires or the vehicle could be damaged as a result. Only use snow chains that are approved by Mercedes-Benz. Any authorized Mercedes-Benz Center will be glad to advise you on this subject. i When driving with snow chains, you may wish to deactivate the ESP® ( page 93) before setting the vehicle in motion. This will improve the vehicle's traction. 329
