The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery .
Always wear eye protection.
Battery acid contains sulfuric acid. Always wear
gloves and eye protection.
No
- sparks
- flames
- smoking.
When a battery is charged, it produces hydrogen
gas which is explosive and could cause personal
injury.
Always keep the battery well out of reach of chil ­
dren.
& WARNING
Whenever working on the battery or on the electrical system,
there is the risk of injury, accident and even fire. Read and heed the
following WARNINGS:
• Always wear eye protection. Do not let battery acid or any lead
particles get on your skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury.
• Battery acid contains sulfuric acid. Sulfuric acid can cause
blindness and severe burns.
- Always wear gloves and eye protection. Do not tilt the
battery because acid could leak out of the ventilation openings.
- If you get battery acid in your eyes or on your skin, immedi­
ately rinse with cold water for several minutes and get medical
attention.
& WARNING (continued)
-If you should ingest any battery acid, seek medical attention
immediately.
• Do not expose the battery to an open flame, electric sparks or
an open light.
• Do not smoke.
• Do not interchange the positive and negative cables .
• When working on the battery, be sure not to short -circuit the
terminals with tools or other metal objects. This would cause the battery to heat up very quickly, which could lead to damage or
explosion and personal injury.
• When a battery is charged, it produces hydrogen gas which is
explosive and could cause personal injury.
• Always keep the battery well out of the reach of children.
• Before work is done on the electrical system, disconnect the
negative ground cable.
• Before performing any work on the electrical system, switch off
the engine and ignition as well as any electrical equipment. The
negative cable on the battery must be disconnected.
If you are just
going to replace a light bulb, then it is enough to switch off the
lights.
• Before disconnecting the battery, switch off the anti-theft
alarm system! Otherwise you will set off the alarm.
• 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. .,,_

& WARNING (continued)
• 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! 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 .
• If 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.
Fig. 245 Engine
compartment : Connec­
tors for charger and
jumper cables
Always read and heed all WARNINGS below=> & and=> &
in "Working on the battery" on page 312.
- Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge
the battery.
- Open the hood => page
300.
-Open the red cover on the positive pole=> fig. 245.
- Connect the charger connectors according to the instruc-
tions to the
jump start bolts. (Bolts under the red cover=
" posit ive", Bolts with hex head= "negative").
- 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. .,_

Checkin g and fillin g -
--------------~-
•
-Now remove the clamps fo r the charging eq uipment.
- Close t he red cover on the positive pole.
- Close the hood~
page 301.
A discharged battery can freeze at temperatures of only O °C. A llow
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.
Batt ery c harg ing (Ma ximum ch arging rate of 30
a mps /14 .8 Volt )
When charging at /ow voltages (e.g. with a trickle charg er), the
ba ttery cables do not have to be disconnected first. The battery caps
should
not be opened when charging a battery.
I t is not necessary to remove the battery from the luggage compart­
ment .
Fa st cha rging the batt ery (chargi ng ra te ab ove 14 .8
Volt s)
For technical reasons do not use a battery charger that uses vo ltage
greater than 14.8 Volts to charge your vehic le's battery.
& WARNING
C harging a battery can be d angerou s.
• Alwa ys follo w the oper ating instruct ions pro vided b y the
battery charger manuf acturer when charging your b attery .
• Neve r charge a frozen battery. It m ay explode be cau se of gas
tr apped in the i ce. Allow a frozen battery to thaw out fir st.
• Do not reuse batteries wh ich were fro zen. The battery housing
m ay hav e crac ked and wea kened when the b atte ry fro ze .
• Charge the battery in a well ventilated area. Keep away from
open fla me or ele ctri cal s par k. Do not smok e. Hydrogen ga s gener ­
ated by the battery is explo sive.
&_ W ARN ING (c ontinued )
• To redu ce the danger of explo sion, never connect or d isconnect
c h ar ger cable s while the charger is ope rat ing .
• Batte ry acid that may spill durin g charging should be w ashed
off with a sol ution of warm water and b aking soda to neutralize
the acid .
0 Note
Never use a fast charger as a booster to start the engine . This wi ll
seriously damage sensitive electronic components, such as control
units, re lays, radio, etc ., as well as the battery charger. •
Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Intelligent energy management in your vehicle is responsib le for
distributing the e lectrica l energy throughout your vehicle
~ page 269 . The intelligent energy management system will keep
the engine battery charged better then vehicles without this system.
To make sure the additional electrical energy is availab le once again
after you have changed the battery, we recommend that you insta ll
batteries of the same type and manufacture only (the same as those
insta lled at the t ime your vehicle was de livered). Specif ications are
listed on the battery housing . Your authorized Audi dealer wi ll then
code the battery management con trol unit.
I f it is not possib le to use a battery of this type, the new battery must
have the same capacity, voltage (12 volts), amperage, construction
and p lug sealing .
When installing the battery, make sure the ignition and all electrical consumers are tur ned off.

0 Note
Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
Because of the problem of proper disposal of a battery, we recom ­
mend your authorized Audi dea ler change the battery for you.
Batteries contain sulfuric acid and lead and must always be
disposed of properly in compliance with all environmental regula ­
tions . Disposing of vehicle batteries improperly is very dangerous to
t he environment. •

the windshield washer reservoir.•

-Tires and wheels
PW-------------------
If you wish to improve comfo rt when operating the vehicle at
normal load (up to 3 occupants) , you can adjust tire pressures to
those spec ified for normal vehi cle load . Before operating the vehi cle
at maximum load, you must in crease the tire pressures to those
specified for ma ximum vehi cle load =>
&.
Bear in mind that the tire pressure monitoring system can on ly
m onito r the t ire pressures you have stored. The syste m does not
recognize the load condition of your vehic le .
The effect iveness of the tir e pr essure moni toring syste m will be
impaired if you store normal load pressures but then operate the
veh ic le a t its ma ximum load=>& . See the
illustrat ion=>
