Washer fluid - filling
Washer fluid is used for cleaning the head-
lamps and windows. Washer fluid with anti-
freeze must be used during winter.
The windscreen and headlamp washers share
a common reservoir.
IMPORTANT
Use washer fluid with antifreeze during the
winter to avoid freezing in the pump, reser-
voir and hoses.
For capacities, see Washer fluid - quality and
volume (p. 396).

Battery
The service life and function of the battery is
influenced by factors such as the number of
starts, discharging, driving style, driving con-
ditions, climatic conditions etc.
The starter battery is a traditional 12 V bat-
tery.
•
Never disconnect the battery when the
engine is running.
•
Check that the cables to the battery are
correctly connected and properly tight-
ened.
WARNING
•
The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.
•
The battery contains sulphuric acid,
which can cause serious burns.
•
If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.
IMPORTANT
Only a traditional battery charger should
ever be used when charging the battery.
IMPORTANT
If the following instruction is not observed
then the energy saving function for info-
tainment may be temporarily disengaged,
and/or the message in the information dis-
play about the main battery's state of
charge may be temporarily inapplicable,
following the connection of an external
battery or battery charger:
•
The negative battery terminal on the
car's starter battery must never be
used for connecting an external bat-
tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting with battery (p. 265) for
a description of how the cable clamps
must be attached.
