Using the pump lever, slowly turn the lowering
screw on the jack through approximately one
revolution and carefully lower the vehicle
Y
( page 285).
X
Put the jack aside.
X
Pull the rod with the smallest diameter off the
pump lever.
The shortened pump lever serves as a wheel
wrench extension.
X
Starting with the middle rod, slide the wheel
wrench extension as far as it will go onto the
wheel wrench.
X
Using the extended wheel wrench, tighten the
wheel bolts evenly in a crosswise pattern in
the sequence indicated (: to B).
Tighten the wheel bolts to the following tight-
ening torques:
Steel wheel 240 Nm
R
Light-alloy wheel 180 Nm
R
Tighten the wheel nuts to a tightening torque
of 180 Nm.
X
Push the piston on the hydraulic jack in again
and close the pressure release screw.
X
Vehicles with all-wheel drive: turn the jack
spindle clockwise as far as it will go
Y
( page 285).
X
Stow the jack and the rest of the vehicle tools
in the vehicle again.
i You can now fit the hub caps on steel wheels
with wheel bolts. The fitting procedure
depends on whether the hub cap acts as a
trim that covers the whole wheel, or just cov-
ers the centre.
X
Wheel with hub cap: position the opening for
the tyre valve in the hub cap over the tyre
valve.

retaining lugs of the central hub cap over the
wheel bolts.
X
Hit the middle of the hub cap to engage it on
the wheel.
X
Secure the faulty wheel in the spare wheel

bracket ( page 290).
X
Check the tyre pressure of the newly fitted
wheel and adjust it if necessary.
Observe the recommended tyre pressure
Y
( page 275).
X
Retighten the wheel bolts or wheel nuts to the
specified tightening torque after the vehicle
has been driven 50 km.
When using a wheel or spare wheel with a new or
newly painted wheel rim, have the wheel bolts or
nuts retightened again after approximately
1000 to 5000 km. Observe the specified tight-
ening torque.
i Vehicles with the tyre pressure monitor sys-
tem: all fitted wheels must be equipped with
functioning sensors.

General notes
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
You will find a table with the recommended tyre
pressures for various vehicle loads on the inside
of your vehicle's fuel filler flap.
The recommended tyre pressures can also be
found in the "Tyre pressure table" section in
these Operating Instructions (
wheel/tyre combinations for your vehicle can
be found on the tyre pressure table. Further
information on wheel/tyre combinations can be
obtained at any qualified specialist workshop.
