current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hanging the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor .
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent addit ives in the oil will make fresh
oil look dark after the eng ine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine). Your
Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to fol­
low recommended maintenance and use re­
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover­
age unless you present to the dealer proof in
Checking and filling 231
the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see ¢
page 204) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary .
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­
el, see
Note .
If the yellow engine oil level warning symbol
in the instrument cluster
II! lights up, you
should check the oil level as soon as possible
¢
page 232. Top off the oil at your earliest
convenience

238 Checking and filling
@ For the sake of the environment
Because of the problem of proper disposal
of brake fluid as we ll as the special tools
required and the necessary expertise, we recommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outside temperatures or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level should also be
checked each time the battery is charged
<=:> page 240.
Have the battery checked when you take your
vehicle in for service . You are well adv ised to
replace a battery that is older than 5 years .
With certain types of airbag deployment, the battery is disconnected from the vehicle elec­
tr ical system for safety reasons
c::> & in Re­
pair, care and disposal of the airbags on
page 165.
Disconnecting the battery terminals
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected. These functions have
to be relearned after the battery terminals are
connected again. To prevent this , the battery
should only be disconnected from the vehicle
e lectrica l system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capability over a longer period
c::> page 202. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven- ience
functions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
During the winter months, battery capac ity
tends to decrease as temperatures drop. This
is because more power is a lso consumed whi le
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Audi
deale r check the capacity of the vehicle bat ­
tery before winter sets in
c::> page 240 . A well
charged battery will no t only prevent star ting
problems when the weather is cold, but will
also last longer .
@ 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
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check any­
thing in the luggage compartment,
read and
heed all WARNINGS
c::> .&,.
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle elec­
trical system to prevent injury.
The following WARNINGS are very
important when working on the battery:

A WARNING
Whenever working on the battery or on
the electrical system, there is the r isk of
injury, acc ident and even fire. Read and
heed the following WARNINGS:
- Always wear eye protection. Do not let
battery acid or any lead particles get on
yo ur sk in or cloth ing . Sh ield your eyes.
Explosive gases can cause blindness or
other injury.
- Battery acid contains sulfuric acid . Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye p rotection.
Do not tilt the battery because ac id
could leak out of the vent ilation open­
ings.
- If you get battery acid in your eyes or
on your sk in, immed iately r inse with
cold water for severa l m inutes and get
medical attention .
- If you should ingest any battery acid,
seek med ical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cab les.
- When working on the battery, be sure
not to short-c ircuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
wh ich could lead to damage or explosion
and personal in jury.
Checkin g and fillin g
-When a battery is charged, it produces
hydrogen gas which is explos ive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the elect rical sys­
tem, disconnect the negative ground ca­ ble.
- Before performing any work on the e lec­
trical system, switch off the eng ine and
ignit ion as well as any electrical equip­
ment . The negative cable on the battery
must be disconnected. If yo u are just go­
ing to replace a light bulb, then it is
enough to switc h off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you wi ll set off the alarm.
- When disconnecting the battery, first
disconnect the negat ive cab le and then
the posit ive cab le.
- Before reconnecting the batte ry, ma ke
sure all e lectr ica l consumers are sw itch ­
ed off . Reconnect the pos it ive cable first
and then the negative cable. Neve r inter ­
change the cables - this could start a fire!
- Never cha rge a frozen or a thawed-out
battery.
It could exp lode! If a battery has
frozen, then it must be replaced . A dis­
charged battery can freeze over at 32
°F
(0 oc).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! A l­
ways rep lace a damaged battery.

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
bulb. This appl ies 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 ser ious cuts, and parts
must be correctly taken apart and then prop­
erly 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 discharge lamps (Xenon lights):
Fuses and bulbs
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Head lights w ith Xenon light can be identified
by the high voltage sticker.
LED headlights* require no maintenance.
Please contact your authorized Audi dealer if a
bulb needs to be replaced.
_& WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death .
- Xenon bulbs are pressur ized and can ex­
plode when being changed .
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
&_ 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 improperly performed work.
(D Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
¢page 227¢ &.
- It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
