destroy electronic components, such as
the alternator.
i Mercedes-Benz recommends that you
have all work involving the battery, e.g.
removal, charging and replacement, car-
ried out at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Installation location of the battery Your vehicle is equipped with a battery in the
engine compartment. It is located on the front
bulkhead under the filter box on the right-
hand side of the vehicle when viewed in the
direction of travel.

Charging and fitting the battery
G
Risk of injury
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 charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process. G
Risk of injury
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while it is still installed. However, the bat-
tery must always be disconnected first.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
X Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X Refit the charged battery.
To do this, follow the steps described in
"Removing the battery" (Y page 233) in
reverse order. Reconnecting the battery
! Always reconnect the battery in the
sequence described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose. Make sure that
a cell cap is fitted on the side of the battery.
X Close the bonnet.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R set the time (Y page 102).
R reset the panorama sliding sun-
roof* (Y page 127)
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 68). Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R jump-starting may only be performed when
the engine and catalytic converter are cold.
R do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R only use jump leads which have a sufficient
cross-section and insulated terminal
clamps. 234 Jump-startingPractical advice

i
Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Never start the vehicle using a rapid battery
charger. G
Risk of injury
There is a risk of acid burns when jump-start-
ing a vehicle due to the gases which escape
from the battery. Do not lean over the battery
while the engine is being jump-started. G
Risk of explosion
Gases escaping from the battery during jump-
starting may cause minor explosions. Avoid
creating sparks. Keep naked flames away
from the battery, and do not smoke.
Comply with safety precautions and take pro-
tective measures when handling batteries.
You will find these under "Battery" in the
index.
X Make sure that the two vehicles do not
touch.
X Depress the parking brake firmly.
X Move the selector lever to P.

Points to remember
G Risk of accident
If you have the vehicle towed, you must use a
rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the voltage supply
or the vehicle's electrical system.
The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. Then, greater braking force will be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
force.
Do not tow the vehicle if the key cannot be
turned in the ignition lock. If this is the case,
the steering is locked and the vehicle cannot
be steered.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle.
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,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/hm ust
not be exceeded.
For towing distances over 50 km, the entire
vehicle needs to be lifted up and transpor-
ted.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Tow-starting the vehicle is not permitted.
R The vehicle is equipped with 4MATIC and
must not be towed with the front or rear
axle raised.
R If the engine does not start, try jump-start-
ing it (Y page 234).
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, have it carried away on a trans-
porter or trailer.
R The automatic transmission selector lever
must be in the Nposition when towing the
vehicle away.
R If you are towing the vehicle, move the
automatic transmission selector lever to
N and turn the key to position
2 (Y page 61) in the ignition lock.
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. Otherwise, you
could be locked out when pushing or tow-
ing the vehicle.
Deactivate tow-away protection* before
the vehicle is towed ( Ypage 55). Fitting the towing eye
Vehicles with a trailer tow hitch: if you
intend to use the vehicle for towing, fit the ball
coupling (Y page 162)and connect the towbar
to it.

as axle or steering components. Otherwise,
the vehicle could be damaged.

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.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted 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 238 FusesPractical advice

correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, a circuit overload
could cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
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 fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R fuse box on the driver's side of the dash-
board*
R fuse box in the engine compartment on the
driver's side
R fuse box in the stowage well under the lug-
gage compartment floor on the right-hand
