Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv
ice station.
Before you check anything in the engine com
partment,
a lw ays rea d an d h eed all WARN
INGS c::> .& in Working in the engine compart
ment on page 216.
The engine oil must be changed accord ing to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di
minish gradua lly during normal vehicle use .
Under some ci rcumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traffic con
ditions, or have your vehicle where tempera
tures remain below freezing for extended pe
riods .
Detergent addit ives in the oil w ill make fresh
oil look dark after the engine has been run n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary ex
pertise required , we strongly recommend that
you have your o il changed by an authorized
Audi de ale r or a qual ified servi ce station.
If you choo se to c hang e y our oi l y our self,
please note the followi ng important informa
tion :
A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from runn ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the rea ch of childre n.
- Continuous contact with used eng ine o il
is harmfu l to your sk in. Always protect

Changing brake fluid
Have the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
ev ery tw o y ear s. Always use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r can be difficult to

have the brake fl uid changed by yo ur a utho r
ized
Audi dealer. Your dea ler has the correct tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
-- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can resu lt from o ld or inap
propriate brake f lu id. Observe these pre
cautions:
- Use only brake f luid that meets SA E
spe cifi cation
J 17 03 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always chec k with your authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi
c iency of the brakes as well as your
safety . T h is i:ou ld result in an ai;i;ident.
(D Note
Brake fluid will damage the pai nt of you r

- Always wear eye protection. Do not let
battery acid or any lead particles get on
your sk in or cloth ing . Sh ield your eyes .
Explosive gases can cause blindness or
other injury .
- Battery acid contains sulfur ic acid . Sulfu
ric acid can cause blindness and severe
burns .
- Always wear gloves and eye protection.
Do not t ilt the battery because acid
could leak out of the venti lation open
ings.
- If you get battery acid in yo ur eyes or
on your skin, immediately rinse with

medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the posi tive and neg -
ative cab les.
= When wo rking on the battery , be sure
not to short -circuit the termina ls with
tools or other metal objects . This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces hydrogen gas which is explosive and
cou ld cause personal injury .
- Always keep the battery well out of the
reach of chi ldren .
- Before work is done on the e lectrica l sys
tem, disconnect the negative ground ca ble .
- Before perform ing any work on the elec
trical system, sw itch
off the engine and
ignition as well as any electrical equip
ment . The negative cable on the batte ry
must be disconnected . If you are just go
ing to rep lace a light bu lb, then it is
enough to sw itch
off the ligh ts.
- Before disconnect ing the battery, switc h
off the anti-theft alarm sys tem! Othe r
wise you will 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 battery, make
sure all e lectr ical consumers are sw itch
ed off. Reconnect the pos it ive cable first
and then the negative cable . Never inter
cha nge the cables - this could start a fi re!
- Never charge a frozen or a thawed-out
battery .
It could explode! If a battery has
frozen , then it must be replaced . A dis
charged batte ry can free ze over at 32 °F
(0 °C) .
-Make sure the vent hose is a lways attach

gine is run ning, otherwise , you will dam
age electronic components in the electr i
cal system.
- If your vehicle is going to stand for a
long period of time without be ing driven,
protect the battery from "freezing", oth
erw ise it will be damaged and will then
have to be replaced .
- When open ing the doors, the windows
lower approximately 10 mm automati
cally. This function is not ava ilable when
the battery is disconnected, which
means there is a risk that the door sea l
o r the window could be damaged.
230 Checking and filling
(D Note
Never use a fast charger as a booster to
start the engine. This will seriously dam
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi
cations and dimensions as the original equip
ment battery.
Intelligent energy management in your vehi
cle is responsible for distributing the electri
cal energy throughout your vehicle
~ page 190. The intell igent energy manage
ment system will keep the engine battery
charged better than vehicles without this sys
tem. To make sure the additional electrica l en
ergy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and manu
facture only (the same as those installed at
the time your vehicle was delivered). Specifi
cations are listed on the battery housing. Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management funct ions cor
rectly after replacing the battery .
The new battery must have the same capacity,
voltage (12 volts), amperage, construct ion
and plug sealing.
When installing the battery, make sure the ig
nition and all electr ical consumers are switch
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you . Batteries contain su lfuric acid and l
ead and must always be disposed of prop
erly in compliance with all environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi
ronment.
