202 Caring and cle aning
_& WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce t he risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp meta l components when
wash ing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be de layed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applicat ions .
@ Note
- If you wash t he vehicle in an automatic
ca r wash, you must fold the exterior m ir­
r o rs in to reduce the r isk of damage to
t h e m irrors. Power foldi ng exterior m ir­
r o rs* must on ly be folded in and o ut us­
i ng the p ower folding function.
- To prevent pa int damage, do not wash
t h e ve hicle in direc t sunli ght. -
To reduce the ris k of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted veh icle compo­
nents:

220 Checking and Filling
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outs ide temperatu res or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility. The e lectrolyte level shou ld also be
checked each time the battery is charged
c:>page222.
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
With certain types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons
c;, .&. in Re­
pair , care and disposal of the airbags on
page 156.
Disconnecting the battery terminals
Some vehicle functions such as power win­
dows are unavai lable if the battery termina ls
are d isconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
To reprogram the functions, proceed as fol­ lows:
Function Reprogramming
Power window one-c;, page 40, Correcting
touch up/down power window mal-
function functions
Remote control key If the vehicle does not
or react to the key, it
convenience key must be synchroni zed
c:>page 33
Digital clock c:>page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually sca led back or switched
off. This reduces energy consumption and
maintains starting capability over a longer pe­
riod
c;, page 190. Some of the conven ience
functions may not operate, such as the interi­
or lights or power seat adjustment. The con ­
venience functions will be availab le aga in
when you switch on the ignition and start the
engine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop. This
is because more power is also consumed wh ile
sta rting, and the headlights, rear window de­
fogger, etc. , are used more often.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Aud i
dealer check the capacity of the vehicle bat­
tery before winter sets in ~ page 222. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
A WARNING -
-Work on the battery requ ires expert
know ledge. Contact your authorized Audi
dealer qualified repair facility for infor­
mat ion regarding the vehicle battery.
There is a risk for chemical burns or ex­
p losions.
- Never open the vehicle batte ry . Do not
try to change the battery electrolyte lev­
el. Otherwise explosive gas will escape
from the battery and increase the risk of
an explosion .
(i) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it w ill not freeze. This will ..,.

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 . T his appl ies especia lly to the l ight bu lbs
in the front of your car which you can on ly
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop ­
e rly put 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 bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas disc harg e lam ps (X enon lig ht s):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon light can be identified
by the high voltage sticker.
LED headlights* require no ma intenance .
P lease contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­ placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death .
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial training, instruct ions and equ ip­
ment. -
On ly an authorized A udi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from imprope rly performed work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
~ page 21 a ~ .11::..
- It is best to ask your authorized Audi
dea ler whenever you need to change a
bulb.
