Have the battery checked when you take your ve­
hicle in for service. You are well advised to re­
place a battery that is older than 5 years .
Disconnecting the batt ery terminal s
Some vehicle funct ions (power w indow regula ­
tors , fo r example) are lost if the battery termi­
na ls are disconnected. These functions have to be
re learned after the battery terminals are con ­
nected again. To prevent this , the batte ry shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
V ehicl es not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period of
several days or weeks , e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains s tarting ca­
pability over a longer period<=> page 140. Some
of the convenience funct ions may not operate ,
such as the inter ior lights or powe r seat ad just­
ment. The convenience functions will be ava ilable
again when you switch on the ignition and start
the eng ine.
Wint er op erati on
During the winter months, battery capacity tends
to decrease as temperatures drop . This is because
more power is also consumed w hile start ing , and
the head lights, rear w indow defogger, etc., are
used more often.
Avoid unnecessary power consumption, part icu­
l arly in city traffic o r when traveling only short
d ista nces . Let you r a utho rized Aud i dea le r check
the capacity of the vehicle battery before w inter
sets in <=> page 167. A well charged battery will
not on ly prevent starting prob lems when the
w eather is cold, but will also last longer.
R eplacing battery
The new battery mu st ha ve the same capacity,
voltage
(12 vo lts), amperage, construction and
p lug sealing, as the original battery . Specifica ­
tions are listed on the battery housing. Batteries
specia lly deve loped by Audi fulfill the mainte­
nance, output, and safety requ irements .
Check ing and fillin g
When installing the battery, make sure the igni­
tion and all electrica l consumers are switched off
<=> 0 .
We recommend that you use main tenance-free or
cycle -res istant /leak-p roof batteries according to
the standards TL
825 06 (from Apri l 2008) and
VW 7
50 73 (from Apr il 2010).
Replac ing the bat tery shou ld be carried by a
qualified workshop. Please fo llow the ins truc ­
tions on the battery cover .
(D Note
-All work on the battery req uires techn ica l
knowledge . Please contact an Audi dealer ­
ship or another authorized facility for ques­
tions about the battery - danger of ac id
burns and explosion ha zard!
- The battery must not be opened! Do not try
to change the battery's liquid level, other­
w ise detonating gas will escape from the
battery- exp losion hazard!
- The AGM battery in the luggage compart­ ment cannot leak, because the e lectrolyte
for this battery is absorbed into a special glass mat . This leak-proof battery must not
be replace with a convent ional battery.
- Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery ac id can leak out.
- Battery holder and terminals always have to
be sec ured correctly .
- Before all work on the battery follow the
warnings be low <=>&. in Working on the bat­
tery on page 166.
@ For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your autho rized
Audi dealer change the battery for you . Bat­
teries contain sulfur ic acid and lead and must
a lways be d isposed of properly in compliance
with all envi ronmental regula tions . Disposing
of vehicle batteries improperly is very danger­
ous to the environment . Make sure that the
removed battery cannot overba lance, other­
wise sulf uric ac id might escape!

WARNINGS
Q page 155, Working in the en­
gine compartment .
CD Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE( +) to POSITIVE
( + ), and NEGA TIVE(-) to NEGATIV E(-)
gro und post of the battery manager control
unit.
- Check that a ll screw plugs on the battery
cells are screwed in firmly . If not, tighten
plugs prior to connect ing clamp on negat ive
battery terminal.
- Please note that the procedure for connect­
i ng a jumper cable as described above ap­
plies specifically to the case of your vehicle
being jump started. When you a re g iving a
ju mp sta rt to another vehicle, do
not con­
n e ct the neg ative(- ) ca b le to the negative
( - ) terminal o n the discharged battery @.
Instead, se curely connect the negative(-)
cab le to either a solid metal component
that is f irm ly bolted to the engine block or
to the engine block itself . If the battery that
i s bei ng charged does not vent to the out­
s ide , escap ing battery gas could ignite and
explode!
