.&_ WARNING
-
Do not repair fuses and never replace a
blown f use with one that has a hig her amp
rating. Th is can cause damage to the elec­
trica l system and a fire .
(D Note
-If there a re multiple fuse values in a cell
in the fo llow tables, for examp le
5/10/20, it is because of equipment -re ­
lated differences . Replace the burned
fuse with an identical new one.
- If a new f use should burn out again
shortly after you have installed it, have
the electrical system checked by your au­
thorized Aud i dealer or qualified repair
facility as soon as possible.

258 Fuses a nd bul bs
Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . T his appl ies especia lly to the l ight bu lbs
in the front of your car which you can on ly
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop ­
e rly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas disc harg e lam ps (X enon lig ht s):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon light can be identified
by the high voltage sticker.
LED headlights* require no ma intenance .
P lease contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­ placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death .
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial training, instruct ions and equ ip­
ment. -
On ly an authorized A udi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from imprope rly performed work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
~ page 21 a ~ .11::..
- It is best to ask your authorized Audi
dea ler whenever you need to change a
bulb.

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. ..,. •

@ 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.

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

Improper hook-up of jumper cables can ru­
in the generator.
- Always connect POSITIVE( +) to POSI ­

- 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
