re commends hav ing the e lectro lyte level check
by an au thor ized A udi dealer or au thori ze d Audi
Serv ice Facility when there a re
high outs ide tem
peratures or when driving a ll day. The elect rolyte
level sho uld a lso be checked each time the bat
tery is charged
c::> page 200.
Have the battery checked when you bring your ve
hicle in for an inspection. It is a good idea to re
p lace the battery if it is more than 5 years old .
T he batte ry is located in the eng ine compar tment
and is practically
maintenance-free .
Disconnecting the battery terminals
The battery shou ld not be d isconnected. Severa l
veh icle functions (power w indows, for example)
w ill be lost w hen the b attery is disconne cted. The
f u nctions mus t be reprog rammed after connect
in g the battery. To avo id th is, the battery shou ld
only be disconn ecte d from the vehicle e lectrica l
system when it is abso lutely necessary.
T o reprogram the func tions, proceed as follows:

Not running the vehicle for long period s of
time
If you do not drive your vehicle for severa l days o r
weeks, electrical components are gradually re d u ced or switched off . This reduces energy con
s u mp tion and mai ntain s the vehicle's ability to
st art over a long perio d of time
c::> page 1 21.
Some conven ien ce f unctions, such as inter ior
li ght ing o r power seats* may not wor k. T hese
convenience functions will be availab le aga in
once you sw itch the ignition on and start the en
gine.
Winter operation
D ur ing the winte r mon ths, it is common for the
batte ry capac ity to decrease as the temperatures
become lower . This is because more power is
needed to start the vehicle and components such
as the headlights and the rear window defogger
a re used more freque ntly .
Avoid using power unnecessa rily, espec ia lly in
c ity dr iving o r on short t rips. Have your author
i z ed Audi dealer or author iz ed Audi Se rvice Facili
ty check the battery capacity be fore the start of
winter
c::> page 200 . A well -cha rged battery will
not only reduce sta rting prob lems in cold wea th
e r, bu t it will a lso l ast longer.
.&_ WARNING
- W ork on the b attery requires e xper t knowl
e d ge. Con tact an a uthor ized Audi dealer or
author ized Audi Se rvice Facility for info rma
tion rega rding the vehicle batte ry. There is a
-
ris k for chemical burns or e xplosions . ..,.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It i s becom ing increasingly 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 ab le 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 .
<( co .... N ,.__
N .... 0 ,.__
> co
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts must be correctly taken apart and then proper ly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been properly re
sealed.
For 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 bulbs and the expert ise.
Gas discharge lamps (Xenon lights):
Due to the high electrical voltage, have the bulbs
replaced by a qualified technician . Headlights
with Xenon light can be identif ied by the high
voltage sticker.
LE D headlights* require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
A WARNING
Contact w ith high-voltage components of the
electrical system and improper replacement
of gas discharge (Xenon) headlight bulbs can
cause serious personal injury and death.
- Xenon bulbs are pressurized and can ex
plode when be ing changed.
- Changing Xenon lamps requires the special
training, instructions and equipment .
- Only an authori zed Audi dea ler or other
qualified workshop should change the bulbs
in gas discharge lamps .
A WARNING
There are parts with sharp edges on the open
ings and on the bulb holders that can cause
ser ious cuts.
- If you are uncerta in about what to do, have
the work performed by an authorized Audi
dealer or other qualified workshop . Serious
personal injury may resul t from improperly
performed work .
(D Tips
-If you still prefer to rep lace the light bu lbs
you rself , be aware that the engine compart-
Fuses and bulbs
ment is a hazardous area to work in
¢ page 188¢ &.
-It is best to ask your authorized Audi dealer
whenever you need to change a bulb.
