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. Th is applies especia lly to the light bu lbs
i n the front of your car which you can only
reach through the engine compartment ,
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
e rly p ut 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 bu lbs
for you, since your dealer has the proper tools, the correct b ulbs and the expertise.
Gas disc harge la mp s (X enon li ght s):
Due to the high electrical voltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight can be identified
by the high voltage stic ke r.
LED headlights* requ ire no ma intenance .
Please contact your autho rized Aud i deale r if a
bu lb needs to be replaced.
Fu ses and bulb s
A WARNING
Contact with h igh-vo ltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified wor kshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders tha t can
cause serious c uts.
- If you are uncertain abo ut what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Ser ious personal inj ury may result
from improperly performed work.
(D Tips
- If you must replace the light bulbs your­
sel f, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
¢ page 214, Engine
compartment¢ ,&..
- It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb.

268 Emergency situations
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 vehicle,
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 214, 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. ..,_
