Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrica l energy
throughout your vehicle
c:> page 194. The intell i­
gent energy management system will keep the
engine battery charged better than vehicles w ith­
out this system . To make sure the additional elec­
tr ical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture only (the same as those installed at the
time your veh icle was delivered). Specif ications
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
e rgy management functions correctly after re­
p lacing the battery.
The new battery must have the same capacity ,
voltage (12-volts), amperage, construction and plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are switched off.
Make sure the ventilation hose on the s ide of
the battery is connected, otherwise fumes or
battery acid can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery. Installing a different type of bat­
tery can cause problems in the vehicle elec­
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery.
Checking and Filling
{® For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.
