Snow chains should only be used on the rear wheels. Follow the manufacturer's mounting instructions. Only use snow chains that are approved by Mercedes-Benz. Your authorized Mercedes-Benz Center will be glad to advise you on this subject. Use of snow chains may be prohibited depending on location.

To help avoid serious damage to your vehicle or tires, use of snow chains is not permissible with the spare wheel. For use of snow chains on tire size 255/45 R18 99H M+S., contact an authorized Mercedes-Benz Center. i When driving with snow chains, you may wish to deactivate the ESP® ( page 73) before setting the vehicle in motion.
