Checking the window washer fluid level – adding fluid

Check the washer fluid level in washer tank (1). If the level is
too low, add ethanol-based window washer fluid.

Be careful not to let dust get into the fluid.
Battery – charging the built-in battery
For safety instructions see 2.3.4 “Battery” (2-32).

Before charging, disconnect the wire from the negative ter-
minal or pull the main battery switch to interrupt the power
supply. Otherwise the alternator may be damaged by peak
voltages.

Before charging, remove all stoppers from the battery open-
ings to ensure sufficient ventilation.
To prevent gas explosions, do not bring fire near the battery
or allow sparks to form.

Interrupt the charging process if the temperature of the bat-
tery fluid exceeds 45 °C.

Turn off the charger as soon as the battery is completely
charged. Overcharging the battery may result in the follow-
ing conditions:

Battery overheats

Low battery fluid level

Damage to the electrode plates

Do not swap the wires (positive (+) and negative (-)).
For maintenance, disconnect the wires from the battery termi-
nals, except when checking the battery fluid level or measuring
the specific density.
