& WARNING (continued )
• 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 cable 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
explode! If a battery has frozen, then it must be replaced . A
discharged battery can freeze over at 32 °F (0
°CI.
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries which are damaged. There is the danger of
an explosion
I Always replace a damaged battery .
& WARNING
California Proposition 65 Warning :
• Battery posts , terminals and related accessories contain lead
and lead compounds, chemicals known to the State of California
to cause cancer and reproductive problems . Wash hands after
handling.
0 Note
• Do not disconnect the vehicle battery when the ignition is
switched on or when the engine is running, otherwise, you will
damage electronic components in the electrical system.
• I f your vehicle is going to stand for a long period of time without
being driven, protect the battery from "freezing", otherwise it will
be damaged and will then have to be replaced .•
Battery charging
Starting the engine requires a well charged battery.
Always read and heed all WARNINGS below ~ & and~ &
in "Working on the battery" on page 319.
-Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge
the battery.
- Attach the red (positive
8) clamp of the charging equip­
ment to the positive terminal of the battery and the black
(negative(:)) clamp to the jumper terminal.
- Only now plug the mains lead for the charging equip­
ment into the wall outlet and turn it
on~ &.
-Make sure the charging rate is not over 30 amps/14.8
Volt.
-When the battery is fully charged: Turn the charging
equipment off and remove the mains lead from the wall
outlet.
- Now remove the clamps for the charging equipm ent.
A discharged battery can freeze at temperatures of only O °C . Allow
a frozen battery to thaw completely before attempting to charge it
=> ,&. . However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at low voltages (e.g . with a trickle charger ), the
battery cab les do not have to be disconnected first. The battery caps
should
not be opened when charging a battery. ~
Vehicle care

-Checking and filling PW~---=---=----------------
It is not necessary to remove the battery from the luggage compart ­
ment, and it is also not necessa ry t o disco nnec t the cab les.
F a st ch arging th e batt ery ( charging rate above 14 .8
V olts )
For technical reasons do not use a battery charger that uses voltage
greater tha n 14.8 Vo lts to charge your veh ic le's battery.
& WARNING
C harging a b attery can be dangerou s.
• Always follow the operating in structions provided by the
battery charger manufacturer when ch arging your b attery .
• Never charge a frozen battery . It may expl ode because of ga s
t rapped in the ice . Allow a frozen batter y to tha w out fir st .
• Do not reu se batteries which were fro zen. The battery hou sing
m ay have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated are a. Keep aw ay from
open flame or electric al spar k. Do not smoke . Hydr ogen gas gener ­
ated by the battery i s explosive.
• To reduc e the danger of e xplosion , never conne ct or dis conn ect
charger cable s while the charger i s oper ating.
• Fa st charging a batter y is dangerous and should only be
a ttempted by a competent technician with the proper equipment .
• Battery ac id that may spill during charging should be washed
off with a solution of warm water and b aking soda to neutralize
the a cid .
0 Note
Never use a fast charger as a booster to start the engine. This wil l
ser iously damage sens it ive elect ronic compo nents, such as control
units, r elays, radio , etc ., as wel l as the battery charger. •
Battery replacement
The new batte ry mus t have t he s ame s pecificati ons and
dimensions as the original equipment battery.
I ntel ligent energy management in your vehicle is responsible for
distr ibut ing the e lectr ica l energy throughout your veh icle
~ page 274. The inte lligent energy management system will keep
t he engine ba ttery charged be tter than vehicles without t his sys tem.
T o make sure the add it ional electr ical energy is avai lab le once aga in
after you have changed t he battery, we recommend that you ins tall
batteries of the same type and manufacture only (the same as those
insta lled at the time your vehicle was delivered). Specifications are
listed on the battery housing . Your authorized Audi dea ler wi ll then
code the battery management contro l unit .
The new battery must have the same capacity, voltage (12 volts), amperage, construction and p lug sea ling.
When instal ling the battery, make sure the ign ition and all elect rica l
consumers are turned off .
0 Note
Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
'£> For the sake of the environment
Because of the problem of proper disposal of a battery, we recom ­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfur ic acid and lead and must always be
disposed of proper ly i n compliance with all environmental regula­
tions . Disposing of vehicle batteries improper ly is very dangerous to
t he environment .•
