Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
I t is becoming increasing ly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car wh ich you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
;;§ correct bu lbs and the expert ise .

~ Gas discharge lamps (Xenon lights): .... 0 0
3 Fuses and bulbs
Due to the high e lectrica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker.
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
& WARNING ~ -
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-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 deale r or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be awa re that the engine compa rt­
ment is a hazardous area to work in~.&..

Emergency situations
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 engin e con 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 discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
356
frozen battery completely, otherwise 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 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
~page 304.
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.
@ 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
negative ground cable to the negat ive ground
post of the battery manager control unit .
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

started @.
Starting the engine
.. Start the engine on the vehicle providing the
jump start @and let it run at idle .
.. Now start the engine on the vehicle with the
drained battery @ .
.. If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds .
.. Remove the cables when the engines are run­
ning. Remove them in reverse order from the
way they were installed.
.. Close the red cover on the positive terminal.
T he battery is vented to the outside to prevent
gases from enter ing the vehicle interior . Make
s ur e that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals.
_& WARNING
-To avoid serious personal injury and damage to the vehicle, heed all warnings and instruc ­
tions of the jumper cable manufacturer. If in
