Operation Driving instructions Tire speed rating Regardless of the tire speed rating, local speed limits should be obeyed. Use prudent driving speeds appropriate to prevailing conditions. Warning! An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h). The factory equipped tires on your vehicle may have a tire speed rating above the maximum speed permitted by the electronic speed limiter. Make sure your tires have the required tire speed rating as specified for your vehicle in the "Technical data" section ( page 655), for example when purchasing new tires. For information on how to identify the tire speed rating on a tire's sidewall, see "Tire size designation, load and speed rating" ( page 518). If you are uncertain about the correct reading of the information given on a tire's sidewall, any authorized Mercedes-Benz Center will be glad to assist you. Winter driving instructions The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering maneuvers. Do not use the cruise control or DISTRONIC Plus* system under such conditions. When the vehicle is in danger of skidding, move gear selector lever to position N. Try to keep the vehicle under control by corrective steering action. G Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or serious personal injury and possible death, for you and for others. i For information on driving with snow chains, see "Snow chains" ( page 531). Warning! G On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of control loss. 484
