ur ing t he oil leve l
Dete rmining th e oil l evel
• Park your vehicle on a level surface.
• Let the engine run in id le briefly while it is at
operating temperature and then shut the
engine off.
• Wait approximately two minutes .
• Remove the oil dipst ick. W ipe off the oil dip·
stick with a clean cloth and inse rt it all the
way in again.
• Remove the dipstick again and then read the
oi l level ¢
fig. 150 . Add more engine o il, if
necessary ¢
page 215.
Oil level in the G) area
• Do not add any o il.
Oil level in the @area
• You may add oil. After adding oil , the level
shou ld be in the@area.
Oil l evel in th e@ area
• You must add oil. After adding oil, the level
shou ld be in the@area.
D epending on the way the vehicle is driven
and the operating conditions, oil consumptio n
can be up to a 1/2 quart per 600 mi les
(0.5 liter per 1,000 km) . Consumption may be
h igher with in the first 3,000 miles (5,000
km) . Because of th is, the engine oil leve l must
be checked regularly . It would be best to
check each time you refue l your veh icle and
befo re long drives.

• After two m inutes check the oil leve l again
¢ page 215, Checking the engine oil level .
• Add oil, if necessa ry.
• Close the eng ine o il filler cap and push the
d ipstick al l the way in.
A WARNING
- When adding oil, do no t let o il drip o nto
hot engine components. There could be
ris k of a f ire.
- T he o il filler cap mus t be p roperly se·
cured to preven t oil from bei ng sprayed
on t he hot engine a nd exhaust system
when t he engine is running -fire haza rd!
- Always clean s kin th oroughly if it comes
into contac t with engine oil.
(D Note
- T he oil level cannot be above the@
range, beca use thi s ca n cause damage to
t he cat alytic conve rter or the engine .
Contact yo ur autho rize d Audi deale r o r
qualified repair facility to have excess oil
extracted if necessary.
- Do not mix any addit io na l lubr icants into
the engine oil. Damage cause by such ad·
ditives is not covered by the warranty .

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant
addi tive wi th dist illed wate r is recom mend ed.

tant if yo u live in a region whe re the win­

Checking brake fluid level

alwa ys read and heed all WARN ·
INGS r:=:,page 210 .
~ Read the brak e fluid level from the brake
fluid reservo ir
r:=;, fig . 153, r:=:, page 212,
fig. 149 .
The brake f luid leve l mus t be be­
tween the "MIN" and "MAX " ma rkings.
The location of the brake flu id reservo ir can be
seen in the engi ne compa rtment illust ra ti on
¢ page 212 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . Thi s is not cause for alarm.
If the brake fluid level falls
considerably be ­
low the "MIN" mark, the b rake wa rning/ind i­
cato r light . (U .S . models)/ . (Canadian
models) will come on
r:=;, page 18 . Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized A udi dealer or other quali­
f ied fac ility and the ca use corrected . If the
br ake fluid level is too low, the brake warning/
indica tor light w ill illuminate. Contact an au·
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moist ure from the air. If
the water content in the brake fluid is too
Che cking and Fillin g 219
high, co rrosion in the brake system may resu lt
after a period of time . The boiling point of the
brake f lu id will also decrease conside rably and
decrease braking performance.
T herefore, the brake fluid must be changed
eve ry two year s. Always use new brake f luid
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoi r can be difficu lt to
reach, therefore, we recomm end that you
have the brake fluid changed by your author­
i z ed
Audi dealer . Your dealer has the correct
tools, the right brake flu id and the know-how
to do this for you .
A WARNING
-
-Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal containe r
out of the rea ch of children!
- Brake failure can resu lt from o ld or inap­
p rop riate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SAE
spec ificat ion
J 1703 and conforms to
Federa l Motor Ve hicle Standard 116.
Always check with your authorized Audi
dealer to make sure yo u are using the
cor rect bra ke fluid. The cor rect type of
brake f luid is also i nd icated on t he
brake f lui d rese rvoir.
- The bra ke flu id must be new. Heavy us e
of the brake s can cause a vapo r lock if
the b ra ke fluid is left i n the system too
l ong . This can se riously affect the effi ­
ciency of the brakes as we ll as your
safety . This co uld resu lt i n an accident .
(D Note
Brak e fluid will dam age the pa int of your
vehicle .
@ For the sake of the environment
Because of the p rob lem of proper disposal
o f bra ke fluid as well as the spec ial too ls
r equired and the necessary exper tise, we
recommend that yo u have the brake flu id
changed by yo ur authorized Audi dea ler.
