Information for 4MATIC vehicles
!
Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged.
Vehicles with 4MATIC may either be towed away
with both axles on the ground or be loaded up
and transported.
If the vehicle has transmission damage or dam-
age to the front or rear axle, have it transported
on a transporter or trailer.
In the event of damage to the electrical sys-
tem: if the battery is defective, the automatic
transmission will be locked in position P. To shift
the automatic transmission to position N, you
must provide power to the vehicle's on-board
electrical system in the same way as when jump-
starting (

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.
!
Only use fuses marked with an "S" for the
fuse box in the engine compartment and
under the rear bench seat. Components or
systems could otherwise be damaged.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components on the
circuit and their functions will fail.
Blown fuses must be replaced with fuses of the
same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
The fuse allocation chart is located in the fuse
box under the rear bench seat (
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre.
