Winter Driving
Have your car winterized at your authorized Mercedes-Benz dealer before the onset of winter.
• Change the engine oil if the engine contains an oil which is not approved for winter operation.
For viscosity (SAE/CCMC class) and filling quantity, see Capacities: Fuels, Coolants,
Lubricants etc. in Index.
• Check engine coolant anticorr osion/antifreeze concentration.
• Additive for the windshield washer and headl amp cleaning system: Add MB Concentrate "S"
to a premixed windshield washer solvent/ant ifreeze which is formulated for below freezing
temperatures (see Index).
• Test battery: Battery capacity drops with dec reasing ambient temperature. A well charged
battery helps to ensure that the engine can be started, even at low ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on all four wheels for the winter season.
Observe permissible maximum speed for M+S rated radial-ply tires and the legal speed limit.
Note:
In winter operation, the maximum effectiveness of the Antilock Brake System (ABS), Acceleration Slip Regulation
(ASR) or the Electronic Stab ility Program (ESP) can only be achieved with M+S rated radial-ply tires and/or snow
chains recommended by Mercedes-Benz. Snow chains maximize performance.
Snow Chains
Use only snow chains that are tested and recommended by Mercedes-Benz. Your authorized Mercedes-Benz
dealer will be glad to advise you on this subject. Ch ains should only be used on the rear wheels.
Follow the manufacturer's mounting instructions. Snow ch ains 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.
For tips on driving on slippery winter roads, refer to In dex. Vehicles with Acceleration Slip Regulation (ASR) or
Electronic Stability Program (ESP): When driving with snow chains, press the ASR or ESP control switch, refer to
Index.
Model C 43 AMG
Important !
Use of snow chains is permissible only on winter tire size 215/45 R 17 H M+S. Refer to "Rims - Tires" in section
"Technical Data" (see Index).
Travelling Abroad
Abroad, there is a widely-spread Mercedes-Benz service network at your disposal. If you plan to travel into areas
which are not listed in the index of your dealer directory, you should request pertinent information from your
authorized Mercedes-Benz dealer.
Example
Checking Coolant Level
To check the coolant level, the vehicle must be parked on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the reservoir.
Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain
plugs
for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see Coolants in Index.
Warning!
In order to avoid possibly serious burns or injury:
•Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the
cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
•Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow
engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.
•Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately,
scalding hot fluid and steam will be blown out under pressure.
•Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes
into contact with hot engine parts.
Checking Engine Oil Level
Example
1. Oil dipstick
2. Oil filler cap
To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check
engine
oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan.
Oil Dipstick:
Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three
seconds to obtain accurate reading.
Oil level must be between the
lower (min) and upper (max)
mark of the dipstick.
Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 I).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by
the Mercedes-Benz Limited Warranty.
For low engine oil level warning lamp, see Index.
Wheels
Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your
authorized Mercedes-Benz dealer for further information. See your authorized Mercedes-Benz dealer for information
on tested and recommended rims and tires for summer and wi nter operation. They can also offer advice concerning
tire service and purchase.
Tire Replacement
Front tires should be replaced in sets. Rims and tires must be of the correct size and type. For dimensions, see
"Technical Data". We recommend that you break in new ti res for approx. 60 miles (100 km) at moderate speed. It is
imperative that the wheel mounting bolts be fastened to a tightening torque of 80 ft.lb. (110 Nm) whenever wheels are
mounted. For rim and tire specifications, refer to "Technical Data".
Warning !
Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace
them. When replacing rirns, use only genuine Mercedes-Benz w heel bolts specified for the particular rim type. Failure
to do so can result in the bolts loosening and possibly an accident.
Rotating Wheels
Rotation of wheels with summer tires does not apply to m odel C 43 AMG. The wheels can be rotated according to the
degree of tire wear while retaining the same direction of travel. Rotating, however, should be carried out at the
scheduled service intervals, before the characteristic tire wear pattern (shoulder wear on front wheels and tread
center wear on rear wheels) becomes visible, as otherwise the driving properties deteriorate.
Important !
Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward
movement.
Notes:
Thoroughly clean the inner side of the wheels any time you rotate the wheels or wash the vehicle underside. The use
of retread tires is not recommended. Retread tires may adversely affect the handling charac teristics and safety of the
vehicle. Dented or bent rims can caus e tire pressure loss and damage to the tire beads. For this reason, check rims
for damage at regular intervals. The rim flanges must be checked for wear before a tire is mounted. Remove burrs, if
any. Check and ensure proper tire inflation pressure after rotating the wheels. For Tire Inflation Pressure refer to
Index.
Spare Wheel (except C 43 AMG)
Important !
The spare wheel rim is mounted with a full size tire of the same type as on the vehicle, and is fully functional.
However, that spare wheel rim is weight optimized an d has a limited service life of 12 000 miles (20 000 km) use
before a standard wheel rim must replace it. In the case of a flat tire, you may temporarily use the spare wheel. Do
not operate vehicle with more than one spare wheel mounted.
Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward
movement. If the arrow on tire side wall does not point in direction of vehicle forward movement when using the spare
wheel, observe the following restrictions:
• Drive to the nearest tire repair facility as soon as possible.
For rim and tire specifications, refer to "Technical Data".
Warning !
The spare wheel rim is for temporary use only. Use for over a total of 12 000 miles
(20 000 km) may cause wheel rim failure leading to an accident and possible injuries.
Battery
Warning !
Failure to follow these instructions can result in severe injury or death. Never lean over batteries while
connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in
contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek
medical help if necessary. A battery will also produ ce hydrogen gas, which is flammable and explosive.
Keep flames or sparks away from battery, avoid im proper connection of jumper cables, smoking etc..
Important !
Battery maintenance information:
The battery is located in the trunk under the trunk floor. The fluid level must be checked at every A and B service.
Always insure that the fluid level is at the specified maximum level and that only distilled water is used. Failure to
maintain proper fluid level may result in cell deterioration and possible battery rupture. The service life of the battery is
dependent on its condition of charge. The battery should alwa ys be kept sufficiently charged, in order to last an
optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for
short distance trips, or if it is not used for long periods of time.
Only charge a battery with a battery charger after the battery has been disconnected from the vehicle electrical circuit.
Always disconnect the battery negative lead first and connect last. When removing and connecting the battery,
always make sure that all electrical consumers are off and the electronic key is in steering lock position 0. The battery
and its vent tube must always be securely installed when the car is in operation. While the engine is running the
battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components
would be damaged.
Note:
After reconnecting the battery also resynchronize the Express feature of the power windows, the
sliding/pop-up roof, and the Electronic Stability Program (ESP) (see Power seats, front, Head
restraints, Power windows, Sliding/pop-up roof, and Electronic stability program in Index).
Battery Recycling
Batteries contain materials that can harm the environment with improper disposal. Large 12 Volt storage batteries
contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to
accept old batteries for recycling.
Front Head Restraints
Warning !
For your protection, drive only with properly positioned head restraints. Adjust head restraint to support the
back of the head approximately at ear level. Do not drive the vehicle without the seat head restraints.
Head restraints are intended to help reduce injuries during an accident.
For positioning of head restraints refer to sections Manual Seats, Power Seats, and Head Restraints, Rear in Index.
