Battery
General information
All work on the battery requires technical
knowledge.
The battery is located behind the cover i n the
l uggage compa rtme nt. Remove the cover by
pushing it to the left and lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main­
tenance se rv ices .
You are we ll advised to replace a battery that
is older than S years .
Disconnecting the battery terminal s
Some vehicle functions (power window reg u­
lators, for example) are lost if the battery te r­
mina ls are disconnected . T hese functions have
to be relearned after the battery termina ls are
connected again . To prevent th is, the battery
shou ld only be disco nnected from the ve hicle
electrica l system when abso lutely necessary
f o r repai rs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies­
cent current consume rs even when the vehicle
i s not used . With extended pe riods of non-use
i n the
cold season, you should have the ve hi­
cl e battery removed by an autho rized Aud i
de aler or qu alified workshop and stored in an
frost -free place. This preven ts the battery
from "freezing" and thereby being dest royed.
