Observe the instructions and safety notes on
changing a wheel (
/
page 258).
#
For safety reasons, only use wheel bolts or
wheel nuts which have been approved by
Mercedes-Benz and for the wheel in question.
When you install the steel spare wheel, it is essen-
tial you use short wheel bolts for a steel wheel.
Using other wheel bolts when installing the steel
spare wheel may damage the brake system.

#
Clean the wheel and wheel hub contact surfa-
ces.
#
Vehicles with ultrawide-base tires: first install
the adapter for the more narrow spare wheel
on the wheel hub.
#
Slide the wheel which is to be re-install onto
the wheel hub or the adapter for the spare
wheel and push it on.
Vehicles with steel wheels
#
Use the short wheel bolts intended for the
steel spare wheel, which are found in the vehi-
cle tool kit.
#
Screw in the wheel bolts until they are finger-
tight.
Vehicles with light alloy wheels
#
Use the long wheel bolts intended for the light-
alloy spare wheel, which are found in the vehi-
cle tool kit.
#
Screw in the wheel bolts until they are finger-
tight.
Wheels with wheel nuts
#
Front wheels with wheel nut cover: press the
wheel nut cover onto the wheel nuts.
#
Screw in three wheel nuts over the fixing discs
of the wheel nut cover.
#
Turn the wheel so that the wheel bolts are in
the middle of the holes.
#
Screw in the remaining wheel nuts.
#
Slightly tighten all the wheel nuts.

WARNING Risk of accident due to incor-
rect tightening torque
The wheels could come loose if the wheel bolts
or wheel nuts are not tightened to the prescri-
bed torque.
#
Ensure that the wheel bolts or wheel nuts
are tightened to the prescribed tighten-
ing torque.
#
If you are not sure, do not move the vehi-
cle. Contact a qualified specialist work-
shop and have the tightening torque
checked immediately.
Requirements:
R
The new wheel has been installed
(
/
page 263).
Observe the notes on raising the vehicle
(
/
page 261).
Vehicles with rear wheel drive
Only use the middle rod and the pump lever rod
with the largest diameter for the jack as a lug
wrench extension. Only insert the middle rod on
the lug wrench, and always as far as it will go. Oth-
erwise, the rods could bend and deform so much
that they can no longer be used as pump levers for
the jack.
Vehicles with Super Single tires: if you mount the
spare wheel on the rear axle, do not exceed the
maximum speed of 34 mph (55 km/h) and the
maximum distance of 62 miles (100 km). Other-
wise, the rear axle differential could be damaged
due to the different wheel speeds.
#
Using the pump lever, slowly turn the drain
screw on the jack approximately one revolution
and carefully lower the vehicle.
#
Place the jack to one side.
