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”.
Rotating wheels
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 as
recommended by the tire manufacturer, 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.
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 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 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 see
inside of fuel filler flap and also page 278.
Wa r n i n g !
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.

Spare wheel
Important!
The spare wheel rim size is 4
1/2 Bx15H2 with
inflatable, collapsible tire, size 165 -15 89 P.
You should inflate the spare tire using the supplied air
pump.
In the case of a flat tire, you may temporarily use the
spare wheel, while observing the following restrictions:
• Do not exceed vehicle speed of 50 mph (80 km / h).
• Drive to the nearest tire repair facility to have the
flat tire repaired or replaced as appropriate.
• Do not operate vehicle with more than one
collapsible spare wheel / tire mounted.
For additional information, refer to page 374.
Wa r n i n g !The dimensions of the spare wheel are different
from those of the road wheels. As a result, the
vehicle handling characteristics change when
driving with a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quick as
possible.

Changing wheels
Move vehicle to a level area which is a safe distance
from the roadway.
1. Set parking brake and turn on hazard warning flasher.
2. Move selector lever to position “P” and turn off engine (manual transmission to 1st or reverse gear).
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 an level road, place one chock in front of
and one behind the wheel that is diagonally
opposite to the wheel being changed.
Wa r n i n g !
The jack is designed exclusively for jacking up the
vehicle at the jack take-up brackets built into either
side of the vehicle. To help avoid personal injury,
use the jack only to lift the vehicle during a wheel
change. Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet away
from the area under the lifted vehicle. Always
firmly set parking brake and block wheels before
raising vehicle with jack.
Do not disengage parking brake while the vehicle is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully seated in the jack take-up bracket. Always
lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.

4. Remove the two-piece wheel wrench from the vehicle tool kit and assemble (see page 323).
5. Using the wrench, loosen but do not yet remove the wheel bolts. 6. Place jack on firm ground. Position jack (1) under
the take-up bracket (2) so that it is always vertical
(plumb-line) as seen from the side, even if the
vehicle is parked on an incline.
The jack take-up brackets are located directly
behind the front wheel housings and in front of the
rear wheel housings.
7. Jack up the vehicle until the wheel is clear of the ground. Never start engine while vehicle is raised.

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
