G
Risk of injury
Only charge the installed battery with a bat-
tery charger which has been tested and
approved
by Mercedes-Benz. These battery
chargers allow the battery to be charged
while it is still installed. Otherwise, the vehi-
cle's electronic system may be damaged.
Only charge the battery in a well-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions.
This may injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged when still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. G
Risk of injury
There is a risk of acid burns during the
charging process due to the gases which
escape from the battery. Do not lean over
the battery during the charging process.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V. Practical advice

Towing and tow-starting
293Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned. !
When towing, pull away slowly and with-
out

jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-You cannot switch on the ignition
- You cannot move the selector lever to N
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice

Notes on changing 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 will
fail.
i Blown fuses must be replaced with fuses
of the same rating (which can be recog-
nised by the colour and amperage) and
which have the amperage specified in the
fuse allocation chart. A Mercedes-Benz
Service Centre will be happy to advise you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have
the correct amperage for the system con-
cerned. Do not attempt to repair or bridge
faulty

fuses. A circuit overload could other-
wise cause a fire. Have the cause traced
and rectified at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre. !
Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct amperage for the system
concerned.

Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R Main fuse box on the driver's side of the
dashboard
R Fuse box in the boot, on the left-hand side
of the vehicle
Fuse allocation chart The fuse allocation chart is in the main fuse
box in the dashboard. The fuse amperage is
also indicated there. Practical advice
