Notes on 4MATIC vehicles

!
Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
Vehicles with 4MATIC may only either be
towed away with both axles on the ground or
be loaded up and transported.
If the vehicle's transmission, front, or rear axle
is damaged, have the vehicle transported on a
truck or trailer.
In the event of damage to the electrical
system:
If the battery is defective, the automatic trans-
mission will be locked in position j. To shift
the automatic transmission to position i, you
must provide power to the vehicle's on-board
electrical system in the same way as when
jump-starting ( page 295).
Y
Have the vehicle transported on a transporter
or trailer.

Fuses

Important safety notes

G
WARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric cables could be over-
loaded. This could result in a fire. There is a
risk of an accident and injury.
Always replace faulty fuses with the speci-
fied new fuses having the correct amperage.
!
Only use fuses that have been approved
for Mercedes-Benz vehicles and which have
the correct fuse rating for the system con-
cerned. Only use fuses marked with an "S".
Otherwise, components or systems could be
damaged.
!
Make sure that no moisture can enter the
fuse box when the cover is open.
!
When closing the cover, make sure that it
is lying correctly on the fuse box. Moisture
seeping in or dirt could otherwise impair the
operation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings, and
other items of information to be complied with
are, listed in the fuse allocation chart.
The fuse allocation chart is in the fuse box in
the front-passenger footwell (
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized Mercedes-
Benz Center.
