Di sco nnecting the batt ery
Some vehic le functions (power window regulators, for example) are
lost if the battery termina ls are disconnected. These functions have
to be relearned after the battery terminals are connected again . To
prevent this, the battery should only be disconnected from the
vehicle el ectrical system if absolutely necessary.
Vehic les not driven f or lo ng peri o ds a nd sho rt -di stan ce
o pera tion
The battery can a lso become discharged with the veh ic le stationary
by id ling current consumers . When the vehic le is sta tionary
(planned event) during the
cold t ime of the year, you should remove
the battery and store it in a nonfreezing area . This way you prevent
that the battery "freezes" and thereby is destroyed . During the
w arm er time of the year it is sufficient to disconnect the negative
terminal from the battery . Occasionally charge even a disconnected
battery .
Wint er opera ti on
During the winter months, battery capacity tends to decrease as
tempera tures drop . This is because more power is a lso consumed
while starting, and the headlights, rear window defogger, etc., are
used more often .
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling only short distances. Let your authorized Audi dea ler
check the capacity of the vehicle battery before w inter sets in
=>
page 239. A well charged battery will not only prevent starting
problems when the weather is cold, but w ill also last longer.
Replacin g battery
The new battery m ust h ave the same capacity , voltage (12 volts),
amperage, construction and p lug sea ling, as the orig inal battery.
Specif ications are listed on the battery housing. Batteries special ly
developed by Audi fulfil l the maintenance, output, and safety
requirements.
When instal ling the battery, make sure the ignition and all electrica l
consumers are switched off=>
(D.
We recommend that you use maintenance -free or c y c le -resis­
tant /leak -proof
batte ries according to the sta ndards TL 825 06 (from
December 1997) and VW 7 50 73 (from August 2001).
(D Note
• All work on the battery requires technical knowledge . Please
contact an Audi dealership or another authorized fac ility for ques ­
tions about the battery- danger of acid burns and exp losion hazard!
• The battery must not be opened! Do not try to change the
battery's liquid level, otherwise detonating gas wil l escape from the
bat tery -explosion hazard!
• The AGM battery in the luggage compartment cannot leak,
because the electrolyte for this battery is abso rbed in to a special
glass mat . This leak-proof battery must not be replace with a
conventiona l battery.
• Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
• Battery holder and terminals always have to be secured correctly .
• Before all work on the ba ttery follow the
warning s below=> & in
"Working on the battery" on
page 238.
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi deale r change the battery for you .
Batteries contain sulfuric acid and lead and must always be
disposed of properly in comp liance with a ll environmental regula ­
tions . D isposing of vehicle batteries improperly is very dangerous to
the environment. Make sure that the removed batte ry cannot over ­
balance , otherwise sulfuric acid might escape! •

• When disconnecting the battery , first disconnect the negative
cable and then the positive cable.
• Before reconnecting the battery, make sure all electrical
consumers are switched off. Reconnect the positive c able first and
then the negative cable . Never interchange the cables - this could
start a fire!
• Never charge a frozen or a thawed -out battery . It could
e x plode! If a battery has frozen , then it must be replaced . A
discharged battery can freeze over at 32 °F (0 °C I.
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries whi ch are damaged. There is the danger of
an explosion! Always replace a damaged battery .

& WARNING
Charging a battery can be dangerous .
• Never charge a frozen battery . It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first .
• Do not reuse batteries which were frozen . The battery housing
may have cracked and weakened when the battery froze .
• Charge the battery in a well ventilated area . Keep away from
open flame or electrical spark . Do not smoke . Hydrogen gas gener ­
ated by the battery is explosive .
• To reduce the danger of explosion , never connect or disconnect
charger cables wh ile the charger is operating .
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .
0 Note
• Nev e r use a fast charger as a booster to start the engine. This will
seriously damage sensitive electronic components, such as control
units, re lays, radio, etc ., as wel l as the battery charger .
• T he vehicle may be optio nally equi ppe d wi th a ge l batt ery , w hich
can only be charged at a constant current -limited volta ge. To
prevent damage to the battery and the electronics system, a gel
battery that is connected must u nder no circumstances be cha rged
with a quick charger.
