Changing the engine oil
We recommend that have your oil changed by an autho­
rize d Audi de aler or a qualified service s tation.
Before you check any thi ng in the engine compartment, alway s read
and heed all WARNINGS =>
& in "Working in the engine compart ­
ment" on
page 250.
The engine oil must be changed according to the intervals specified in you r War ranty
& Main tenance booklet . This is very important
because the lubricating properties of oil diminish gradually during
normal vehicle use .
Under some circumstances the engine oil shou ld be changed more
frequently . Change oil more often if you drive mostly short
distances, opera te the ve hicle in dusty areas or under predom i­
nant ly stop -and -go traffic conditions, or have your vehicle where
t emperatures remai n below freezing fo r extended periods .
Detergent add it ives i n the oil wi ll make fresh oil look dark after the
engine has been running for a short time . This is norma l and is not
a reason to change the oi l more of ten than recommended.
Because of the problem of proper disposal, along with the special
t ools and necessa ry expert ise required, we strong ly recommend
that you have your oil changed by an authorized
Audi dealer or a
qual ified se rvice sta tion .
If you choo se to change your oil yourself , please note the follow ing
important information :
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle you rself:
• We ar eye protection . _.,

Engine cooling system
Coolant
T he e ngin e cool ant p erform s tw o functio ns: it k eep s th e
e ng ine f rom ov erh ea ting and it pro tects the engine fr om
freezing in the winter.
The cooling system is sealed and general ly requires little attention.
The coo ling syst em has been fil led at the fac tory with a perm an ent
coolant which does not need to be changed. The coo lant consists of
a m ix ture of wa te r and the manufacturer 's gl yco l- b ase dco olant
add it ive G 12++ antifreeze with anticorrosion additives (50% for USA
mode ls; 60% for Canadian mode ls) . T his m ixtu re bo th a ssure s the
n ecessary frost protectio n and p ro tects m etal co mponents in t he
eng ine's cooling system from co rrosion and scaling. It a lso raises
the boili ng poi nt o f the coolant.
D o not reduce the concentrat ion of the coo lant in the summer by
adding pla in wate r. The proportion of coolant additive must be at
least 50 % but not more than 60 % to maintain antifreeze protection
and coo ling eff iciency . If the c oolant frost p ro tecti on is t oo low, the
coo lant could freeze and damage th e vehic le heating and en gine
cool ing sy stem .
For year -rou nd driv ing, ant ifreeze is added at the facto ry fo r tempe r­
atures down to:
• -31 °F ( -35 °C) USA
• - 40 °F ( - 40 °C) Canada.
You can mix the G12 ++ coolan t add itive with othe r additives (G12 +
or G12). A lways check wit h your authorized Audi dea ler.
& WARNING
Before you check anything in the engine co m partment , always
read and heed all WARNINGS

0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold . If necessary, increase the proportion of
coolant additive to 60% .
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result
in damage not
covered by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 202 Engine
compartment: Coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working in
the engine compartment" on
page 250.
Turn off the ignition.
- Let the eng ine cool down.
Place a thick rag over the coolant expansion tank
~ fig. 202 and carefully twist the cap counter-clockwise
~& .
Read the engine coolant level in the open coolant expan­
sion tank~ fig. 202. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 252.
To obtain an accurate reading , the engine must be switched off .
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant l evel is too low, the warning light in the Auto ­
Check System :::::,
page 31 will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
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 system. In the event
of coolant loss, the cooling system should be inspected immedi ­
ately 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
coolant is exceeded as a result of overheating. ..,.

•
The brake fluid reservoir is located at the rear partition of the engine
compartment on the left side~
page 252 .
The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm .
If the brake fluid level falls
considerably below the "MIN" mark, the
brake warning/indicator light (U .S. models :
BRAKE, Canadian models :
(CD) ) wi ll come on
~ page 23 and ~ page 30. Do not continue to
operate the vehicle. The complete brake system should be thor ­
oughly checked by an authorized Audi dealer or qualified workshop
and the cause corrected . If the brake fluid level is too low, the brake
warning/indicator light will illuminate. Contact an authorized Audi
dea ler
immediately .•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air . If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid wil l also
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federa l Motor Vehic le Stan­
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your autho ­
rized
Audi dealer. Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you.
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the reach of children!
& WARNING (continued)
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions :
- Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make sure you are using
the correct brake fluid. The correct type of brake fluid is also
indicated on the brake fluid reservoir .
- The brake fluid must be new . Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long. This can seriously affect the efficiency of the brakes as
well as your safety . This could result in an accident.
0 Note
Brake fluid wil l damage the paint of your vehicle .
ci> For the sake of the environment
Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating conditions, the battery in your Audi does
not need any maintenance. With
high outside temperatures it is
advisab le however to check the fluid level at regular intervals
through the transparent battery housing. Also check the fluid level
each time you charge the battery . After charging the battery
~ page 265, you shou ld likewise check the battery acid level. ...

& WARNING
• To reduce the ri sk of serious injury and vehicle damage.
- Always l ift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
~ page 308 , fig. 230 and
~ page 308, fig. 231.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balan ce . This might happen , for
e xample , when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add correspond ing we ights to maintain the center of
gravity. Otherwise , the vehicle might tilt or slip off the hoist ,
causing ser ious personal injury .
0 Note
• Be aware of the fo llowing po ints be fore l ifting the ve hicle:
- The vehicle should never be lifted o r ja cked up from under ­
neath the engine oil pan , the tran smis sion housing , the front or
rear a xle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame , a rubber
pad must be inserted between the floor jack and the lift points .
- Before dr iving over a workshop hoist , check that the vehicle
weight does not exceed the permis sible lifting capacity of the
hoist .
- Before driving over a workshop hoist , en sure that there i s
sufficient clearance between the hoist and low parts of the
vehicle. •

M ainte nanc e book le t.
Und er diff icult op era ting co nd iti ons, for example at extreme ly low
outsi de temperatures, in very dusty regions, when towing a trailer
very frequent ly, etc ., some service work shou ld be performed
between the intervals specified. This applies particu lar ly to:
• oil changes, and
• cleaning or replacing the air filter.
<£> For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis­
sion s tandards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fue l injection and
emission control systems, and the generally increasing techn ical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by veh ic le
owners.
Also , safety and env ir o nment al concerns place very strict
limits on the nature of repairs and adjustmen ts to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usua lly require special tools,
test ing devices and other equipment availab le to spec ial ly trained
workshop personne l in order to assure proper performance, reli ­
abil ity and sa fety of the vehicle and its many systems.
I mproper maintenance, adjustments and repairs can impair the
operation and reliability of your vehicle and even void your vehicle
warranty. Therefore, proof of servicing in accordance with the main­
te nance schedule may be a condit ion fo r upholding a possible
warranty claim made within the warranty period.
Controls . and equip­
ment . Safety first Vehicle operation
Above all, operational safety can be adverse
ly affected, creating
unnecessa ry risks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dealer or any other properly equipped and qua lified workshop. We
strongly urge you to g ive your authorized Audi dea ler the opportu ­
nity to perform al l scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, original parts and trained spec ia lists
to keep your vehicle running properly.
Performing lim it e d maintenan ce yourself
The following pages describe a limited number of procedures which
can be performed on your vehicle with ord inary tools, should the
