wheel bolt torque MERCEDES-BENZ C-Class 2000 W202 Owner's Manual

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.

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,
until all bolts are tight. Observe a tightening torque of 80 ft.lb. (110 Nm).
13. Ensure proper tire pressure.
