airing or working on the electrical
system, proceed as follows:
–1. Remove the key from the ignition. The
negative cable on the battery must be
disconnected.
– 2. When the repair is finished, reconnect
the negative pole of the battery.
● Switch off all electrical devices before re-
connectin
g the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Ensure that the vent hose is always connec-
ted t
o the battery.
● Never use damaged batteries. This could
cau
se an explosion! Replace a damaged bat-
tery immediately. CAUTION
● Nev er di
sconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components. Charging the battery
Terminals for charging the battery are fitted
in the en
gine c
ompartment. –
Note the w
arnings ››› in Important safety
w arnin
gs for handling a vehicle battery on
page 290 and ››› .

.

– Connect the charger clamps as described
to the
positive pole of the battery (+) and
exclusively to an earth on the bodywork
(–).
– Only use a charger which is compatible for
use w
ith 12 V nominal voltage batteries.
The charge must not exceed a voltage of 15
V.
– Now connect the battery charger to the
pow
er socket and switch on.

Important: Before you charge the battery
make sure you read the manufacturer's in-
structions for using the battery charger. WARNING
Never charge a battery that has frozen: re-
p l
ace battery! Failure to do so may lead to an
explosion. Note
Use only the terminals in the engine compart-
ment t
o charge the battery. Replacing the battery
The new battery should have the same speci-
fic
ation
s (amperage, load and voltage) as the
used battery.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy ›››
page 274.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.
