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 CLK 350, CLK 550: 130 mph (210 km/h) CLK 63 AMG: 155 mph (250 km/h) CLK 63 AMG with increased top speed*: 174 mph (280 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 466), 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 337). 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. 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 personal injury and possible death, for you and for others. i For information on tire speed rating for winter tires, see "Winter tires" ( page 351).
