Fitting twin tyres 14.00 R 20
X Before fitting the inner tyre, check that all of
the spherical spring washers are seated prop-
erly on the wheel bolts. The round side of the
spherical spring washers must face the out-
side.
X
Fit the inner wheel.
X
Check the wheel centring. The wheel bolts
must be located in the centres of the holes in
the rims.
X
Fit the connecting flange in place and screw
on two to three wheel nuts with spherical
spring washers.
X Check that the flange is properly centred. The
wheel bolts must be in the centre of the holes
in the connecting flange.
X Screw on the remaining wheel nuts with
spherical spring washers.
X
Tighten the wheel nuts in a crosswise pattern,
observing the tightening torque while doing
so (
Y
page 428).
X Fit the outside wheel in place and screw on 2
to 3 wheel nuts with spherical spring washers.
X
Check the wheel centring. The wheel bolts
must be located in the centres of the holes in
the rims.
X
Screw on the remaining wheel nuts with
spherical spring washers.
X Tighten the wheel nuts in a crosswise pattern,
observing the tightening torque while doing
so.
X
Check the tyre pressure (
Y
page 405).
X Retighten the wheel nuts on the inner wheel
after 50 km, as well as the wheel nuts of the
outer wheel after a further 50 km
(
Y
page 386).
Retightening the wheel nuts
G
WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Check wheel nuts regularly for tightness.
Retighten if necessary. Replace damaged
wheel nut cover caps and wheel nut covers.
Observe the wheel nut tightening torque.
Always observe the instructions and safety
notes on "Changing a wheel in the event of a flat
tyre" (
Y
page 380).
Observe the wheel nut tightening torques
(
Y
page 428).
Retighten the wheel nuts after 50 km.
When using new or newly painted wheel rims,
check the tightening torque of the wheel nuts
again after travelling approximately 1,000 to
5,000 km.
X
Retighten the wheel nuts in a crosswise pat-
tern.
On light-alloy wheels, the wheel nuts are not
flush with the wheel bolts when tightened.
Electrical fuses
Important safety notes
G
WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may
result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new
fuses of the correct amperage.
The individual electrical circuits are protected
by safety fuses or automatic circuit-breakers.
Blown fuses or defective automatic circuit-
breakers must be replaced with equivalent fuses
with the fuse ratings recommended in the fuse
allocation chart. Fuses with the same fuse rating
are the same colour.
You can obtain further information from any
Mercedes-Benz Service Centre.
The fuse allocation chart is on the inside of the
main fuse carrier cover.
If the new fuse which has been inserted also
blows, have the cause traced and rectified at a
qualified specialist workshop.
X If a circuit fails, switch off the consumer and
turn the ignition back to position 0.
