Bulbs
Replacing bulbs
For your safety, we recommend that you hove
your authorized Audi dealer replace any 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
bulb. 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 holders 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 p roper­
l y resea led.
For your safety, we recommend that you have
you r authorized Aud i dea ler replace any bulbs
for you, since yo ur dealer has the proper too ls,
the correct bulbs and the expertise .
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the
bulbs replaced by a qualif ied techn ic ian.
Headlights wit h Xenon light are identified by
the high voltage sticker.
_&. WARNING
Changing Xenon lamps witho ut the neces­
sa ry equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
-

"" N
0 ::.,: co ,...., \!) ..,.,
,...., ..,., ,....,
-On vehicles equipped with gas discharge
bulbs (Xenon light)* life-threatening in­
jur ies can result from improper handling
of the high-voltage portions of such
lamps!
- Only your authorized Audi dealer or
qualified workshop should change the
bulbs in gas discharge lamps. There are
parts w ith sharp edges on the openings
and on the bulb holders that can cause
serious cuts.
If yo u are uncertain about
what to do, have the work performed by
an authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
(D Tips
- If you still prefer to replace the light
bulbs yourse lf, be aware that the engine
compartment is a hazardous area to
work
inqpoge 212 ¢ A .
-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 emer­
gency crews and working per sonnel who
have the necessary tools and equ ipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicle s with an automati c 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
discha rged or wea k batte ry, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en­
g ine .
Jumper cables
Use only jumper cab les of sufficiently
large cross section to carry the starter cur rent
safely. Refer to the manufact urer's spec ifica­
ti ons.
Use on ly jumper cables with
insulated te rmi­
na l clamps wh ic h are d istinctly mar ked :

A discharged battery can freeze at tem­
pe rat ures just below 32 °F (0 °C). Before
connecting a jumper cable, you must

- Do not allow batte ry acid to contact eyes
or skin . Fl ush any contacted a rea wi th
wate r im media tely.
- Imp roper use of a booster battery to
s tart a vehicle may cause an explosion.
- Vehicle batter ies generate explosive gas­
es . Keep sparks, flame and lighted ciga­
rettes away from ba tte ries .
- Do not try to jump start a ny ve hicle w ith
a low ac id leve l in the battery .
- The vo ltage of the booster batte ry m ust
a lso have a 12-Vo lt rat ing . The capacity
(A h) of the booster batte ry should not b e
lowe r than that of the discharged bat­
tery . U se o f batt erie s of d iffe ren t voltage

@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charg ing the
battery, never connect the negative
ground cable to the battery negat ive post
because the ba ttery manager system must
be ab le to detect the battery's state of
charge. Always connect the negative
g round cab le to the negative ground pos t
of t he battery manager cont ro l unit.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described b elow!

To avoid serious personal injury and dam­
age to the vehicle, heed all warnings and
in structions of the jumper cable ma nufac-
turer . If i n dou bt, call for road servic e.
Ill>

2 76 Em ergency sit uat ions
-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 eng ine compart­
ment.
- Do not bend over the batteries - danger of chemical burns!
- The battery ce ll locking screws must be
tightened securely .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
9 page 212.
Improper hook-up of jumper cables can ru ­
in the generator.
- Always connect POSITIVE( +) to POS I­
TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that a ll screw plugs on the battery
cells are screwed in firmly . If not, tighten
plugs p rior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­ nect ing a jumper cable as described
above applies spec ifically to the case of
your vehicle being jump started. When
you are giving 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@)
9fig. 212. In­
stead, securely connect the negative(- )
cable to e ither a solid metal component
that is firm ly bolted to the engine block
or to the engine block itself. If the bat­
tery that is being charged does not vent
to the outside, escaping battery gas
could ignite and explode!
