and then the negative cable . Never inter­
change 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 dead battery can freeze over at 32°F (0°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.
&_ WARNING
California Propos ition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
t ive p roblems. Wash hands after han­
dling.
(D Note
- Do not d isconnect t he veh icle battery
when the ignition is on or when the en­
gine is running, otherwise, you will dam­
age ele ctron ic componen ts in the elec tri ­
ca l system.
- If your vehicle is going to stand for a
l ong period of time wi thout being driven,
protect the battery from "freezing", oth­
e rwise it w ill be damaged and wi ll then
have to be replaced.
Battery charging
Starting the engine requires a well charged battery.

c> &. and c> &. in Working on the battery on
page 221.
.. Switch off the ignition and all electrical con­
sumers.
.. Make sure the area is well ventilated when
you charge the battery .
.. Open the eng ine hood
r=;, page 211 .
.. Open the red cover on t he positive pole
r=;, fig. 154 .
.. Clamp the ch arger term inal clamps as in­
structed on the
batter y terminal (+ ) and on­
ly o n the

.. On ly now plug the mains lead for the charg­
ing equ ipment into the wa ll outlet and turn
iton
c> &, .
.. Make sure th e charging rate is not over
30 amps /14 .8 volts .
.. When the battery is fully charged: Turn the
charg ing equipment off and remove the
mains lead from the wall ou tlet .
.. Now remove the clamps for the cha rging
equipment .
.. Close the red cover on the positive pole .
.. Close the hood

A d ischarged bat tery can freeze at tempera ­
tu res of only 32 F
0 (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to charge it
r=;, .&, . However, we recommend not
using a thawed battery again because the bat­
te ry casing can be cracked due to ice forma-
t ion and can leak battery acid . ..,.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specifications.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
Emergency situations 259
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin. Flush any contacted area with
water immediately .
- Improper use of a booster battery to start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
JU ry.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
-Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The capacity (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
¢ page 210.
(D Note
-Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,. •

260 Emergency situations
@ Tips
The disc har ged battery must be properly
connected to the ve hicle's electrical sys ­
tem. W hen jump starting or charg ing t he
battery, never connect the negative
grou nd cab le to the batte ry negat ive post
because the batte ry ma nager sys tem must
be ab le to detect th e ba ttery 's state o f
charge. A lways connec t the nega tive
grou nd ca b le to t he neg ative ground pos t
of the batte ry ma nager con trol unit.
Use of jumper cables
Make sure to connect the jumper cable
clamps in exactly the order described below!

6. Start the eng ine in the vehicle giving the
charge and let it run at idle.
7 . Start the eng ine in the vehicle with the
dead battery and wait two to three m i­
nutes until it "runs smoothly" .
8.
If t he eng ine does not s tart: Stop the
sta rting procedure after 10 second s and
t h en re p eat it after approximately 3 0 sec ­
onds .
9 . In the vehicle that is being jump started,
switch the heater fan and rear window de ­
froster on to reduce any voltage peaks
that may occ ur whe n disconn ecting the
jumpe r cables. The headlights must be
switched off.

10. With the engines running, remove the ca­
b les in
reverse order of the way they were
installed. Make sure the cables do not get
caught in moving engine components.
11. Switch the heater fan and rear window de-
froster off .
12 . C lose the battery cover.
The battery is vented to the outside to prevent
gases from entering the vehicle interior . Make
sure that the jumper clamps are well connect ­
ed with their metal parts in full contact with
the battery termina ls.
.&, WARNING
To avoid serious pe rsonal injury and dam­
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac­
turer. If in doubt, ca ll for road service .
- Jumper cables must be long enough so
that the vehicles do not touch.
- When connecting jumper cables, make
surethattheycannotgetcaughtinany
moving parts in the engine compart­
ment.
- Be fore you check anything in the engine
compartment, always read and heed all
WARNINGS
~ page 210.
(D Note
Improper hook-up of jumper cables can ru­
in the generator.
- Always connect POSITIVE( +) to POSI ­
TIV E(+), and NEGA TIVE( -) to NEGATIVE
( - ) ground post of the battery manager

- Check that all screw plugs on the battery
ce lls are screwed in firmly. If not, tighten
plugs prior to connecting clamp on nega­
tive battery terminal.
- Please note th at the procedure for con­
necting a jumper cable as described
above applies specifically to the case of
your vehicle be ing jump started. When
you are giv ing a jump start to another ve ­
hicle, do
not connect the negat ive( -) ca­
ble to the negat ive( -) term inal on the
discharged battery@~

stead, secure ly connect the negative( -)
cable to either a solid meta l component
that is firmly bo lted to the engine block
or to the engine block itself. If the bat­
tery that is be ing charged does not vent
to the outside, escaping battery gas could ig nite and explode!
- Make sure that the connected positive
terminal clamps have sufficient contact
with metal.
- Do not use the battery negat ive terminal
for jump start ing or a malfunct ion could
occur in the vehicle electrical system .
Emergency towing

truck
General hints
Your Audi requires special handling for tow­
ing.
The following information is to be used by
comme rc ial tow truck operators who know

da mage to the engin e and tr an smi ssion .
- Nev er wrap the safet y chains or wi nch ca­
ble s around the brak e lines.
- To p revent unnecessar y damage , your Aud i
must be t ran spor ted with a flat bed truck.
- To lo ad the vehicle on to the fl at bed , u se
the to w ing loop found in the vehicle tool s
and attach to the front or rear ancho rage
