Battery
General information
Under normal operating conditions, the battery
i n your A ud i does not need any maintenance .
With
high outside temperatures or long dai ly
drives we recommend that you have the e lectro­
l yte level checked by an aut horized Aud i dea ler or
qualified workshop . The e lectrolyte leve l should
also be chec ked each time the batte ry is cha rged
¢ page 198.
Have the battery checked when you take your ve­
hicle i n for service . You are well adv ised to re ­
place a battery that is older than 5 years .
With certain types of airbag deployment, the bat­
tery is disco nnected from the ve hicle elect rical
system for safety reasons
¢ A in Repair , care
and disposal of the airbags on page 141 .
Disconnecting the battery terminals
Some vehicle functions (power window reg ula­
tors, for example) are lost if the battery te rm i­
nals are d isconnected . These funct ions have to be
r elearned after the battery t ermina ls are con­
nected again . To prevent t his, the battery sho uld
o nl y be disconnected from the ve hicle e lectr ica l
system when absolute ly necessary fo r rep airs.
