Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
-
The engine in your Audi is a sophisticated
powerp lant that was built to exacting specifi­
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage interva ls printed in your vehicle 's Warranty
&
Maintenance book let matters a lot more to­
day than it did years ago. Audi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um­
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with d iese l eng ine) to
help keep your veh icle's engine running
smoothly and help prevent the format ion of
harmful deposits, sometimes called "s ludge,"
that over time can lead to expens ive repairs.
At the time of printing, engine oils ava ilab le in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00 (ve hicles w ith gasoline eng ine) o r VW 507 00
(veh icles w ith diese l eng ine) are synthet ic en­
gine o ils . This does no t mean, howeve r, that
every synt hetic eng ine oil will meet A udi oi l
standard VW 502 00 (veh icles with gasoline
engine) or VW 507 00 (vehicles with diesel
engine). So a lways be sure that you use an ap­
proved o il.
T o he lp preven t the formation of harmfu l de­
posits use on ly oil with the following specifi­
cations printed on the o il container:
- Audi oil standard VW 502 00 (g aso line en ­
gine )
- Audi oil standard VW 507 00 (die sel en-
gine )
Oil container labels may car ry the spec ifica­
t ion sing ly or in combination with othe r desig­
na tions and oil quality standa rds.
Viscosit y
Engine oi ls are graded according to their vis­
cosity . The proper viscos ity grade oil for your
engine depends on climactic or seasona l con­
ditions where you drive . You can use o il with a
viscosity grade of SA E 5W40 across all tem­
perature ranges for normal dr iv ing cond itions .
However, if engine oil viscosity grade SAE
5W40 is not ava ilable, you can also use v iscos ­
i ty grade SAE 5W-30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
(ve hicl es w ith gasoline eng ine) o r VW 50 7 00
(ve hicles w ith diese l engine) specifica tions. .,.

236 Check ing and filling
Engine oil consumption
Th e e ngine in your vehicle depends on an ad e­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to prov ide effec tive l ubrication and
c o oling of i nternal engi ne components, all in­
t e rnal com bustion eng ines consume a certa in
a m ount of o il. O il consumption var ies from
engine to eng ine and may change significant ly
ove r the life o f the eng ine . T ypica lly, eng ines
with a specified break -in per iod (see
<=>
page 207) cons ume 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 oi l, the RPM (revo lutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions. Further fac­
tors are the amount of oil d ilution from water
condensation or fuel residue and the ox ida ­
tion level of the oil. As any engine is subject to
wear as mileage bu ilds up, the oil consump­
tion may in crease over t ime un til replacement
of worn componen ts may become necessa ry.
W ith all these var iables coming into play, no
standa rd rate of o il consumption can be es­
tablished or specified. The re is no alterna tive
to regular and frequen t checking of the oi l lev­
e l, see
Note .
If the ye llow eng ine o il level warn ing symbol
in the in strumen t cluste r

your engine at regular intervals, pref­
erably each time you refuel , and always
before going on a long trip .
-If you have the impression your engine
cons umes excessive amounts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your con cern
prope rly d iagnosed. Keep in m ind that
t he accurate meas urement o f oil c on­

a lwa ys re ad and h eed a ll WA RN­
INGS o .A in Working in the engine compart­
ment on page 231 .
Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the engine coolant leve l from the cool­
ant expansion tank
o fig. 204, o page 233.
With a cold engine, the coolant level should
be betwee n the "min" and "max" markings.
When the engine is warm, the level may be slightly above the "max" marking .
The location of the coolant expans ion tank
can be seen in the engine compartment illus ­
tration
o page 233.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
o page 16 wi ll
illuminate unti l 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 l oss
Coolant loss may indicate a le ak in the cooling
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coo lant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot. Red uce the risk of scald­
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool

escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying light, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, the ethylene glycol in engine cool­
ant can catch fire.
0 Note
Do not add any type of radiator leak seal­
ant to your veh icle's engine coolant . Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct io n and performance of your

brake fluid leve l must be between the "MIN"
and "MAX" markings.
The location of the brake fl uid reservoir can be
seen in the engine compartment illustrat ion
9 page233.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/ind i­
cator light
1111 (U.S. models)/ . (Canadian
models) will come on
q page 14. Do not con­
tinue to operate the vehicle . T he complete
brake system should be thoroughly checked by an authorized Audi dealer or other quali­
fied fac ility and the cause corrected.
If th e
brake flu id level is too low, the brake wa rning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by on experi­
enced technician.
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
a fter a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt to
reach, therefore, we recommend that you
have the brake fluid changed by your author ­
ized
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 stor­
ed only in the closed origina l container
out of the reach of children!
- Brake failure can result from old or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spec ification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
Always check with your authorized Aud i
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

Battery
General information
Under normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance . With
high outside temperatures or
long dai ly dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility. T he electrolyte level shou ld also be
checked each time the battery is charged
-:;, page 245.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 167.
Disconnect ing the battery terminals
Some vehicle functions (power w indow regu­
lators, for example) are lost if the battery ter­
minals a re d isconnected. These functions have
to be relearned after the battery terminals a re
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lec trica l system whe n absolu tely ne cessa ry
f or repairs.
Checkin g and fillin g 243
Vehicles not driven for long periods
If you do no t drive your vehicle over a period
of seve ra l days o r weeks, e lectr ica l compo ­
nents are g radually cut back or switched off .
This reduces energy consumption and main­
ta ins starting capability over a longer period
¢
page 204. Some of the convenience func­
tions may not operate, such as the inter ior
l igh ts or the power seat adjus tment. The con­
venience functions will be ava ilab le aga in
whe n you swi tch on the ignition and sta rt the
engine.
Winter operation
During the winte r months, battery capacity
tends to dec rease as temperatures drop. This
i s because more power is a lso consumed wh ile
s ta rt ing, and the headlight s, rea r window de­
fogger, e tc., are used more ofte n.
Avoid unnecessary powe r consumpt ion, par­
ticu larly in city traffic o r when traveling only
sho rt distances. Let yo ur au thoriz ed Aud i
de aler check the cap acity of the vehicle b at­
tery before winter sets in~ page 245. A well
charged bat tery will not on ly prevent starting
problems w hen the weather is cold, but w ill
a lso last longer.
{!) Tips
If yo ur vehicle is left s tandin g for seve ral
weeks at extreme ly low tem peratures, the
vehicle battery sho uld be removed and
stored w here it w ill not freeze . T his will
prevent it from be ing damaged and having
to be replaced.

- Do not smoke. -
Do not interchange the positive and neg­
ative cables.
- When working on the battery, be s ure
not to short-circu it the terminals with
too ls or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion and pe rsonal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal in jury.
-Always keep the battery well out of the reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negat ive ground ca­
b le.
- Before performing any work on the elec­ trical system, switch off the engine and

the tire manufacturer, determines the correct
tire pressure for the tires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the required tire pressure from the tire
pressure label. The tire pressure label is lo­
cated on the driver's side 8-pillar.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the valve .
Tires and wheels 255
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a journey. Do not
forget to check the tire pressure for the spare
wheel
c::;,page 271.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures on all wheels. In addition, you must then
store the new tire pressures in the tire pres­
sure monitoring system*
c::;, page 266 .
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
[I] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat­
ed on a sticker on the driver's side B-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly .
- The use of incorrect tire pressure values
can lead to accidents or other damage .
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
