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 ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
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 veh icle,
using a
pair of jumpe r cables to start the en­
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can freeze at tem­
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, 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 vo ltage 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 d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in­
jury.
- Never charge a frozen batte ry. 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 batter ies of different voltage or
substantially different capacity (Ah) rat­
ing may cause an exp losion 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 a ll
WARNINGS
¢page 210, Engine com­
partment.
«I) Note
-Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
contro l units, relays, rad io, 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. ..,_

@ Tips
The disc harged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charg ing the
battery, never connect the negative
ground cable to the batte ry negat ive post
because the ba tte ry manager system must
be ab le to detect the battery's state of
charge. Always connect the negative
g round cab le to the negative ground pos t
of t he battery manager cont ro l unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described b elow!

Emergenc y situ ation s 265
Connect POSI TIVE(+) to POSITIVE(+ )
(red )
• Open the red cover on the positive terminal
¢fig. 19 7.
1. Connect one end of the red positive cable
on the jump sta rt bolt
¢ fig. 198 (D (bolt
under the red cover = "positive") of the ve ­
hicle to be started @.
2 . Connect th e othe r end to the pos itive ter-
mi na l@ of the booster battery @.
Connect NEGATIVE( -) to NEGATIVE(-)
(black )
3. Connect one end of the black negative ca­ ble to the negat ive termi na l@ of the
booster b attery @.
4. Connect the othe r end to the jump start
pin @ (bo lts w ith hex head bolt = "nega ­
tive") of the vehicle to be started @.
Starting the engine • Sta rt the engine of the veh icle w ith the
booste r ba tte ry @ . Ru n the engi ne at a
modera te speed.
• Start engine wit h discha rged vehicle battery
@ in the usual manner.
• If the eng ine fails to sta rt, do not keep the
starter c ranking for longer than 10 seconds.
Wait for about 30 seco nds a nd the n try
aga in .
• With eng ine runni ng , remove j umper cab les
from both vehicles in the exact
reverse o r­
de r.
• Close the red cover on the posi tive term inal.
T he battery is v ented to th e outside to p rev ent
gases from en ter ing the veh icle in ter io r. Ma ke
s ur e th at the jumper clamps are well connec t­
ed with their meta l parts in full con ta ct w ith
the battery term inals.
,8. WARNING
To avoid se rious personal injury and dam­
age to the veh icle, heed all warnings and
instructions of the jumper cable man ufac ­
ture r. If in doubt, call for road service .
- Ju mpe r cables m ust be long enough so
that the veh icles d o not touch.

266 Emergency situations
-When connecting jumper cables, make
sure that they cannot get caught in any
moving parts in the engine compart­
ment .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
<=) page 210, Engine com­
partment.
(D Note
Improper hook-up of jumper cables can ru­
in the generator.
-Always connect POSITIVE(+) to POSI­ TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
cells are screwed in firmly . If not, tighten
plugs prior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­
nect ing a jumper cable as described
above applies spec ifically to the case of
you r vehicle being jump started. When
you are giving a jump start to another ve­
hicle, do
not connect the negative(-) ca­
ble to the negative(-) terminal on the
discharged battery@<=)
fig. 198. In­
stead, securely connect the negative(-)
cable to either a solid metal component
that is firmly bolted to the engine block
or to the engine block itself. If the bat­
tery that is being charged does not vent
to the outside, escaping battery gas
could ignite and explode!
Emergency towing
with commercial tow
truck
General hints
Your Audi requires special handling for tow­
tng.
The following information is to be used by
commercia l tow truck operators who know
how to operate their equipment safely.

damage to the engine and transmission .
- Never wrap the safety chains or winch ca­
bles around the brake lines.
- To prevent unne cessary damage, your Audi
must be transported with a flat bed truck.
- To load the vehicle on to the flat bed, use
the towing loop found in the vehicle tools
and attach to the front or rear anchorage
r=) page 266 and ¢ page 267.
.&_ WARNING
=
A vehicle being towed is not safe for pas-
-
sengers. Never allow anyone to ride in a
vehicle being towed, for any reason.
