Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
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 in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- 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 gases .
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 233.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
283

Emergency situations
@ Tips
The discharged battery must be properly con·
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!
Fig. 209 luggage compartme nt: connectors for jump start
cables and charg ing unit
Fig. 210 Jump starting usi ng a battery in anot her vehicle:
A· drained, B • provid ing curren t
The procedure described below for connecting
jumper cables is intended to provide a jump start
for your vehicle.
Vehicle with discharged battery:
.. Set the parking brake and select the P (Park)
selector lever position.
284
.. Switch the ignition and all electrical equipment
off.
Connecting the positive cable (red) to the
positive terminal
.. Open the red cover on the positive terminal
<=:>fig. 209.
1. Secure one end of the positive cable (red) to
the ju mp start connection
(D c:> fig. 210 on
the vehicle to be started @.
2 . Secure the other end of the pos itive cable
(red) to the positive terminal @on the vehi·
cle battery prov iding the current @.
Connecting the negative cable (black ) to the
negative terminal
3 . Secure one end of the negative cable (black)
to the negative term inal @ on the vehicle
batte ry that is providing the current @.
4. Secure the other end of the negative cable
(black) to the jump start connection
@of the
vehicle to be started @.
Starting the engine
.,. First start the engine in the vehicle giving the
charge @ and let it run at idle .
.. Now start the engine in the vehicle with the
drained veh icle battery @.
.. If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds .
.. Once the engine with the drained vehicle bat·
tery has been started, remove the cables in the
reverse order from the way they were installed .
.. Close the red cover on the pos itive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal ports in full contact with the
battery termin als.
.&_ WARNING
To avoid serious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions of the jumper cable manufacturer. If in
doubt, call for road service .
- Jumper cables must be long enough so that
the vehicles do not touch.

-When connecting jumper cables, make sure
that they cannot get ca ught in any mov ing
parts in the engine compartment.
- Do not bend over the batteries - danger of
chem ica l burns!
- The battery cell lock ing screws must be
t ightened sec ure ly.
- Be fore you check anything in the e ngine
compartment, a lways read and hee d all
WAR NINGS
q page 233 .
(D Note
Impro per hook -up of jum pe r cables can r uin

- Always connect POSITI VE (+ ) to POS ITIV E
( + ), and NEGATIVE( -) to NEGAT IVE( -)
g roun d post of t he battery mana ger contro l
u nit.
- Check that a ll sc rew p lugs on t he battery
cells are screwed in firmly. I f not, t ighten
plugs prior to connecting clamp on negative
batte ry terminal.
- Please note that the procedure fo r con nect­
i ng a jumper cab le as desc ribed above ap­
p lies specifica lly to the case of yo ur vehicle
being jump starte d. When you are giv ing a
ju mp s ta rt to anothe r vehicle, do
not con­
n ect the neg ative (-) cab le to the neg ative

q fig. 210. In ste ad , securely connec t the
nega tive ( -) cab le to either a solid me tal
com ponent that is f irm ly bolted to the e n­
gine block o r to the engine bloc k itself. If
the battery that is be ing cha rge d does not
vent to the outs ide, escap ing battery gas
could ignite and exp lode!
