Disconnecting the battery
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this section may lead to
temporary deactivation or
disturbance of the stop-start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the
negative terminal must be opened.
Only use vehicle batteries that allow the fuse box to be mounted above the
vehicle battery.Ensure that the battery is always replaced by the same type of battery.
We recommend that you have the
vehicle battery replaced by a
workshop.

222Vehicle careElectrical systemFuses
Data on the replacement fuse must
match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
● in the front left of the engine compartment
● in left-hand drive vehicles, in the interior behind the storage
compartment, or, in right-hand
drive vehicles, behind the
glovebox
● behind a cover on the left side of the load compartment
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its
melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Fuse extractor
A fuse extractor may be located in the fuse box in the engine compartment.Place the fuse extractor on the
various types of fuse from the top or
