Tire Speed Rating
Model C 43 AMG only: This vehicle is factory equipped with "Z"-rated tires. All other models: These vehicles are factory
equipped with "H"-rated tires, which have a European spee d rating of 130 mph (210 km/h). An electronic speed limiter
prevents your vehicle from exceeding the speed rating. Despit e the tire rating, local speed limits should be obeyed. Use
prudent driving speeds appropriate to prevailing conditions.
Warning !
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 resulting in personal injury and possible death.
Parking
Warning !
To reduce the risk of personal injury as a result of vehicle movement, before turning off the engine
and leaving the vehicle always:
1. Keep right foot on brake pedal.
2. Firmly depress parking brake pedal.
3. Move the selector lever to position "P".
4. Slowly release brake pedal.
5. Turn front wheels towards the road curb.
6. Turn the key to steering lock position 0 and remove.
7. Take the electronic key and lock vehicle when leaving.
Important !
It is advisable to set the parking brake whenever parking or leaving the vehicle. In addition, move selector lever
to position "P". When parking on hills, always set the parking brake.
Winter Driving Instructions
The most important rule for slippery or icy roads is to driv e sensibly and to avoid abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control system under such conditions.
When the vehicle is in danger of skidding, move selector le ver to position "N". Try to keep the vehicle under control by
corrective steering action. Road salts and chem icals can adversely affect braking efficiency.
Increased pedal force may become necessary to produce t he normal brake effect. We therefore recommend depressing
the brake pedal periodically when travelling at length on salt-strewn roads. This can bring road salt impaired
braking efficiency back to normal. A prerequisite is, however, that this is done without endangering other drivers on the
road. If the vehicle is parked after being driven on salt treated roads, the braking efficiency should be tested as soon as
possible after driving is resumed while observi ng the safety rules in the previous paragraph.
Warning !
If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from
around the vehicle with engine running. Otherwise, deadly carbon monoxide (CO) gases may enter
vehicle interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open
a window slightly on the side of the car that is out of the wind.
Deep Water
Caution !
Do riot drive through flooded areas or water of unknown dept h. If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or being ingested by the air intake, possibly causing damage to
electrical components or wiring, to engine or transmission t hat is not covered by the Mercedes-Benz Limited Warranty.
Passenger Compartment
Warning !
Always fasten items being carried as securely as possible. In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless
the items are securely fastened in the vehicle. The trunk is the preferred place to carry objects.
