Environmental note Batteries contain pollutants.
It is against the law to dis-
pose of them with the house-
hold rubbish. They must be
collected separately and
recycled in an environmen-
tally responsible manner. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop, e.g. a
Mercedes-Benz Service
Centre, or to a special col-
lection point for old batter-
ies.
G
WARNING
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries: R
do not lean over the battery.
R do not place any metal objects on a battery.
Otherwise, you could cause a short circuit
and the battery's gas mixture could ignite.
R make sure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials.
R never touch the battery first. To discharge
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
R do not wipe the battery using a cloth. The
battery may explode as a result of electro-
static charge or due to flying sparks.
! Switch off the engine and remove the key
before disconnecting the terminal clamps
from the battery. On vehicles with KEY-
LESS-GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluster are off. You
may otherwise destroy electronic compo-
nents, such as the alternator.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carry out work on batteries yourself, e.g.
removing or charging. Have this work per-
formed 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 fitted in front of the
front bulkhead on the right-hand side of the
vehicle when viewed in the direction of travel. 326

erwise, the vehicle could be damaged. Tow-starting (emergency engine
starting)
When tow-starting, it is importan tthat you
observe the safety instructions (Y page 330)

must not be tow-started. The transmission
may otherwise be damaged.
Before tow-starting the following conditions
must be fulfilled:
R the battery is connected.
R the engine has cooled down.
R the catalytic converters have cooled down.

Important safety notes
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their functions stop
operating. G
WARNING
Only use fuses that have been approved for
Mercedes-Ben zvehicles and which have the
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.
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 .AMercedes-
BenzS ervice Centre will be happy to advise
you.
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-Benzv ehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged. Electrical fuses
