242 Checking and topping up fluids
Replacing the battery
A replacement battery must have the same specifications
as the original equipment battery.
Your vehicle is equipped with an intelligent power management
system to control the distribution of electrical energy ⇒ page 202.
The power management function ensures that the battery is
charged much more efficiently than on vehicles without a power
management system. For this additional power to be available after
replacing the battery, we recommend that the replacement battery
used is of the same make and type as the original-equipment
battery. The battery must be encoded in the control unit for power
management. This has to be done by a qualified workshop.
A replacement battery must have the same capacity, voltage (12 V)
and current rating. It must also have the same dimensions as the
original, factory-fitted battery and have sealed caps. The battery
must comply with the standards TL 825 06 (dated December 1997 or
later) and VW 7 50 73 (August 2001 or later).
Caution
Make sure that the vent hose is always attached to the opening
on the side of the battery. Gases or battery acid can otherwise
escape and possibly cause damage.
The battery holder and clamps must always be correctly secured.
Before starting any work on the battery, always observe the
warnings listed under ⇒ page 240, "Important safety warnings for
handling a car battery".
For the sake of the environment

Batteries contain toxic substances including sulphuric acid and
lead. They must be disposed of appropriately and must not be put
together with ordinary household waste. Make sure the battery
removed from the vehicle cannot tip over. Otherwise, sulphuric acid
could escape.

Windscreen washer

Plain water on its own is not sufficient for the windscreen
washer system.

⇒ fig. 230. Container capacity: ⇒ page 293.
Plain water on its own is not enough to clean the glass properly. It
is therefore advisable to add a suitable washer fluid additive (with
wax solvent) to the water. A washer fluid with freeze-resistant addi-
tive should be used in winter.
Caution
Never put in radiator anti-freeze or other additives.
Never use washer fluid which contains paint thinners or solvents
as it can damage the paintwork.
