zNever expose the battery to naked
flames or sparks.
z A discharged battery can freeze at
temperatures of 0
°C. Defrost the battery
in a warm room before connecting the
jump leads.
z Do not allow battery fluid to contact
eyes, skin, fabrics or painted surfaces.
The fluid contains sulphuric acid which
can cause injuries and damage in the
event of direct contact.
z Wear eye protection and protective
clothing when handling a battery. z
Use auxiliary battery with same voltage
(12 volts). Its capacity (Ah) must not be
considerably less than that of the
discharged battery. Voltage and
capacity information can be found on
the batteries.
z Use jump leads with insulated terminals
and a width of at least 16 mm
2 (25 mm2
for diesel engines).
z Do not disconnect the discharged
battery from the vehicle.
z Switch off all unnecessary electrical
consumers. Infotainment system may be
damaged if switched on while jump
starting.
z Do not lean over the battery during jump
starting procedure.
z Do not allow the terminals of one lead to
touch those of the other lead.
z The vehicles should not touch while jump
starting.
z Apply hand brake.
z Manual transmissi on in neutral,
automatic transmission 3 in P. Connect the leads in th
e order shown in the
illustration:
1. Connect one end of the first jump lead to the positive terminal 1 of the battery
providing the jump start (identified by
“+” sign on battery case or terminal).
2. Connect the other end of the first jump lead to the positive terminal 2 of the
discharged battery (“+” sign).
3. Connect one end of the second jump lead to the negative terminal 3 of the
battery providing the jump start
(identified by "-" sign on battery case or
terminal).
4. Connect the other end of the second jump lead 4 to ground on the vehicle with
the discharged battery, e.g. on the
engine block.

Protection of electronic
components
In order to avoid the breakdown of
electronic components within the electrical
system, never disconnect the battery with
the engine running. Never start the engine
while the battery is disconnected (e.g.
when using jump leads).
To avoid damaging the vehicle, do not
make any modifications to the electrical
system, e.g. connecting additional
consumers or tampering with electronic
control units (chip tuning). Disconnecting/connecting the battery
from/to the electrical system
Disconnect the battery from the vehicle
electrical system before charging:
first detach the negative and then the
positive lead.
Do not reverse the polarity of the battery,
i.e. do not confuse the terminals for the
positive and negative leads. When
connecting, start with the positive lead and
then connect the negative lead.
Vehicle storage
If your vehicle is to be stored for long
periods without use, we recommend you
consult a workshop for advice.
Vehicle care
In caring for your vehicle, observe all
national environmental regulations,
particularly when washing your vehicle.
Regular, thorough care contributes to
improving the appearance of your vehicle
and maintaining its va
lue. It is also a
prerequisite for clai ms made under the
warranty, in the event of paint or corrosion
damage. In the following pages, we give
you tips for vehicle care which, with correct
use, will help to ward off unavoidable and
harmful environmental influences.
9 Warning
Electronic ignition systems generate very
high voltages. Do not touch the ignition
system; high voltage can be fatal.
