Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 220 .
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
l ubricat ing propert ies of o il d iminish gradually
du ring normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authori zed
Audi dealer or
a qual ified service stat ion.
If y ou choo se to chan ge your oil your self , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amou nt of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of childre n.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
«I) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi limited New Vehi­
cle Warranty .
@ For the sake of the environment
-Before chang ing yo ur oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly .
Do not dump it on ga rden soil, wooded

- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
qu ires little attention .
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of
a mixture of
specially conditioned water and the manufactur­
er's g lycol-basedcoo lant additive G 13 antifreeze
w ith anticorrosion addi tives (50% for USA mod­
e ls· 60% for Canadian mode ls). This m ix ture
'
both ass ures the ne cess ary fros t protection and
p rotects metal com ponents in the engi ne's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ra tion of the cool ant in
the s ummer by addi ng p la in water.
The propor­
tion of coolant additive must be at lea st 50 %
but not more than 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coo lant could
freeze and damage the vehicle heat ing and en­
g ine cooling system .
For year -round driving, antifreeze is added at the
factory for temperatures down to:
- -3 1 °F
c -3s0c) usA
- -4 0° F ( -40°C) Canad a.
I f you must add coolant, use a m ixt ure of wa ter
and coolant add it ive. M ixing the coolant additive
with d istilled water is recommen ded.
_& WARNING
B efore you che ck anyt hing i n the engine com ­
partmen t, a lways read and heed all WARN -
226
INGS ~ & in Working in the engine compart­
ment on page 220.
(D Note
- Be fore w inter sets in, have the coolan t
checked to see if the coo lant additive in your
vehicle is suff ic ient to meet the climate con­
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant addi tive to 60% .
- Whe n adding coolant additive to your cool­
ing system, remember:
- We re commend usin g on ly coo lant addi­
tive G12++ o r G13 fo r yo ur vehicle. This
coolant ad dit ive is availab le at authorized
Audi dealers. Other types of antifreeze can
significantly reduce corrosion protection.
The resulting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of radiato r leak sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and perfo rmance of yo ur cooling
system and cou ld resu lt in damage not cov­
ered by your New Ve hicle Li mited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

.,. Read the engine coolant level from the coolant
expansion tank
c> fig . 200, c> page 222,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark­
i ngs . When the engine is warm, the level may
be s light ly above the
"MAX " marking .
T he location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
i=> page 222.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 29 wi ll
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec­
tr ic coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
syst em. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant .
In a
sealed system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing .
(D Note
Do not add any type of radiator leak sealant
to your veh icle's engine coolant. Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .

If you have lost a considerable amount of coo l­
ant, then you shou ld add cold antifreeze and cold
water only whe n the engine is cold.
Always use
new e ngine coolant when refilling.
Do not fill coolant above the "MAX " mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
-- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn
off the eng ine an d allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.

Checking and Filling
-To avoid bein g burned, do not spill anti­
f reeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous . Always store anti­
freeze in its original container and well out
of the reach of children .
- If you dra in the coolant, it must be ca ught
and safely stored in a proper conta iner
clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank is
empty . Air cou ld enter the cooling system
and damage the eng ine .
If this is the case,
do not continue dr iving . Seek professional
ass istance.
- Coolant pollutes the e nvironment a nd could
cause an eng ine fire. Excess coolant will be

low, the brake warning/ind icator light will illumi­
nate. Contact an authorized Audi dealer
immedi ­
a te ly.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake fluid absorbs mo isture from the air. If the
water conte nt in the brake fluid is too h igh, cor­
ros ion in the brake system may resu lt after ape­
riod of time. The boiling poi nt of the brake flu id
will also dec rease cons iderably and decrease
braking pe rformance.
Therefore, the b rake fluid must be changed
e ve ry
two year s.
Always use new b rake fluid wh ich con­
forms to Fede ral Motor Veh icle St andard "FMVSS
116 DOT 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we re commend that yo u have the
b rake fl uid changed by yo ur autho rized
Audi
deal er.
Your dealer has the cor rect too ls, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of chi ldren!
- B rake failure can resu lt from old or inappro­
pr iate brake flu id. Observe these precau­
t io ns:
Ch eck ing and Filling
-Use only brake fluid that meets SAE speci­
ficat ion
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Aud i dealer to make
sure you are us ing the correct brake fluid .
The co rrect type of brake flu id is also i ndi­
cated on the b rake fluid reservoir.
- The brake flu id must be new. Heavy use of
the b rakes can cause a vapo r lock if the
bra ke fluid is left in the system too long.
T his can se riously affe ct the efficiency of
t h e b rakes as we ll as you r safety . This
could resu lt in an accident.
(D Note
B rake flu id will damage the paint of your ve h i­
cle.
@) For the sake of the environment
Because of the p roblem of proper d isposa l of
brake fluid as well as the spec ial too ls re­

Checking and Filling
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi ­
na ls are disconnected. 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 e lectrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and ma intains starting ca­
pab ility over a longer period
c::> page 195 .
Take into consideration that when you unlock
your veh icle, some convenience functions, such
as the interior lights or the power seat adjust­
ment, may not be available. The convenience
functions will be available again when you turn
on the ignition and start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. This is be­
cause more power is also consumed while start­
ing, and the head lights, rear window defogger,
etc., are used more often.
Avoid unnecessary power consumption, particu­
larly in city traffic or when traveling only short
d istances . Let your authorized Audi dealer check
the capacity of the vehicle battery befo re winter
sets inc::>
page 231. A well cha rged battery w ill
not only preven t starting problems when the
weather is cold, but will also last longer.
