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 oper ational 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 markin
g 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.

Add oil to upper (max) mark of the dipstick."HI"
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could caus e damage to engine and catalytic converter not covered
by the Mercedes-Benz Limi ted Warranty. The symbol
flashes in the odometer field if a proper oil level check
cannot be performed. The oil level check
can be repeated after a short while. Perform the oil level check with the dipstick, if it cannot be completed via the
odometer display field. In this case we recommend that you have the system checked at a Mercedes-Benz dealer.
Automatic Transmission Fluid Level
The transmission has a permanent fill of automatic tran smission fluid. Regular automatic transmission fluid
level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or
gear shifting malfunctions, have your authorized Mercede s-Benz dealer check the transmission fluid level.

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. Furthermore - in the event of tire replacement - the spare wheel (except model
C 43 AMG), if possible, should be used on the rear axle. Ri ms and tires must be of the correct size and type. For
dimensions, see "Technical Data". We recommend that y ou break in new tires 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 rims, use only genuine Mercedes-Benz wheel 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
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 w heels 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
characteristics and safety of the vehicle. Dented or bent rims can cause tire pressure loss and damage to the tire
beads. For this reason, check rims for damage at regular in tervals. The rim flanges must be checked for wear before
a tire is mounted. Remove burrs, if any. Check and correct ti re inflation pressure after rotating the wheels. For Tire
Inflation Pressure refer to Index.

Changing Wheels
Move vehicle to a level area which is a safe distance from the road way.
1 . Set parking brake and turn on hazard warning flasher.
2 . Move selector lever to position "P" and turn off engine.
3 . Prevent vehicle from rolling away by blocking wheels with wheel chocks
(not supplied with vehicle) or sizable wood block or stone. When changing a wheel
on a hill, place chocks on the downhill side blocking both wheels of the other axle.
On a level road, place one chock in front of and one behind the wheel that is
diagonally opposite to the wheel being changed.
4 . Using the wrench, loosen but do not yet remove the wheel bolts.
5
. Remove the protective cover from the jack support tube opening by inserting the
screwdriver (supplied in the tool kit) in the opening and prying it out. The tube
openings are located directly behind the front wheel housings and in front of the
rear wheel housings.
6
. Insert jack arm fully into the tube hole up to the stop.
Place jack on firm ground. Position the jack so that it is always vertical (plumb-line)
as seen from the side (see arrow), even if the vehicle is parked on an incline.
7. Jack up the vehicle until the wheel is clear of the ground.
Never start engine while vehicle is raised.
8 . Unscrew upper-most wheel bolt and install alignment bolt (1) supplied in the
tool kit. Remove the remaining bolts. Keep bolt threads protected from dirt and
sand.
9. Remove wheel. Grip wheel from the sides. Keep hands from beneath the wheels.
10. Clean contact surfaces of wheel and wheel hub. Install spare wheel on wheel
hub.
Insert wheel bolts and tighten them slightly. To avoid paint damage, place wheel
flat
against hub and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last wheel bolt.
11. Lower car. Remove jack and insert jack tube cover. Before storing the jack,
the jack arm must be lowered almost to the base of the jack.
Warning !
Always replace wheel bolts that are damaged or rusted.
Never apply oil or grease to wheel bolts. Damaged wheel hub threads should
be repaired immediately.
Incorrect mounting bolts or improperly tightened mounting bolts can cause the
wheel to come off. This could cause an accident. Be sure to use the correct
mounting bolts.
12.
Using the wrench, tighten the five bolts evenly, following the sequence illustrated
above, until all bolts are tight. Obse rve a tightening torque of 80 ft.lb. (110 Nm).
13. Ensure proper tire pressure.

Tire Inflation Pressure
A table (see fuel filler flap) lists the tire inflation pressures specified for Mercedes-Benz recommended tires as well as
for the varying operating conditions.
Important !
Tire pressure changes by approx. 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage - especially in the winter.
Example:
If garage temperature = approx. +68°F (+20°C) and ambient te mperature = approx. +32°F (0°C) then the adjusted air
pressure = specified air pressure +3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values o ffering high driving comfort. Increased inflation pressures for
heavy loads produce favorable handling characteristics with lighter loads arid are perfectly permissible. The ride of
the vehicle, however, will become somewhat harder.
Tire temperature and pressure increase with the vehicle speed. Tire pressure should therefore only be corrected on
cold tires. Correct tire pressure in warm tires only if pressure has dropped below the pressure listed in the table and
the respective operating conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread separation, bulging etc.. Regular tire pressure checks (including the
spare tire) at intervals of no more than 14 days are therefore essential. If a tire constantly loses air, it should be
inspected for damage.
Warning !
Do not overinflate tires. Overinfiating tires can result in sudden deflation (blowout) because they are more
likely to become punctured or damaged by road debris, potholes etc.. Follow recommended inflation
pressures.
Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the
driver's door latch post). Overloading the tires can overheat them, possibly causing a blowout.
