Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasing ly more and more diff i­
cult to replace vehicle light bulbs s ince in many
cases, othe r parts of the car must fi rst be re­
moved before you are able to get to the bu lb .
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correct ly taken apart and then properly put back
together to he lp prevent breakage of parts and
380
long term damage from water that can enter
housings that have not been properly resealed.
Fo r you r safety, we recommend that you have
you r autho rized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bu lbs and the expertise.
Ga s di sc harg e la mp s (Xe non ligh ts):
Due to the h igh electr ical voltage, have the bulbs
rep laced by a qualified technician . Headlights
with Xenon light a re identified by the high volt­
age sticker.
L ED headlight s*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
-Bulbs are pressurized and can explode when
be ing changed. Potent ial r isk of injury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening injuries
can result from improper handling of the
high-vo ltage portions of such lamps!
-Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps . There are parts with
sharp edges on the openings and on the bulb holders that can cause serious cuts. If
you are uncerta in about what to do, have
the work performed by an authorized Audi
dea ler or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work.
(D Tips
-If you still prefer to replace the light bulbs
yourself, be aware that the engine compart­
ment is a hazardous area to work
i n c:> & in
Working in the engine compartment on
page 330 .
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb .

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
CD 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 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
"A h" 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
qpage 330.
CD 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.

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 ground cable to the negative ground
pos t of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

... If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds .
... Remove the cables when the engi nes are run­
ning. Remove them in reverse order from the
way they were installed.
" Close the red cover on the positive 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 parts in full contact with the
battery terminals .
A 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 caught in any moving
parts in the engine compartment.
- Do not bend over the batteries
-danger of
chem ical burns!
- The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c!.> page 330.
(D Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE(+) to POSITIVE
( + ), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager contro l
unit.
- Check that all screw p lugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connecting clamp on negative
battery terminal.
- Please note that the procedure for connect­
i ng a jumper cable as described above ap­
plies specifically to the case of your vehicle
being jump started. When you are giv ing a
jump start to another vehicle, do
not con­
nect the negative (-) cab le to the negative
(-) terminal on the discharged battery @
c!.> fig. 303. Instead, securely connect the
negative (-) cable to either a solid me tal
component that is firm ly bolted to the en­
gine block or to the engine bloc k itself. If
the battery that is be ing charged does not
vent to the outs ide, escaping battery gas
could ignite and explode!
