Changing the engine oil
The engine oil and oil fi lter must be changed according to the mileage
(kilometers) and t ime intervals specified in your vehicle 's Warranty
&
Maintenance booklet . Do not exceed these interva ls -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repairs .
Changing the oil at the recommended intervals is so very impo rtant
because the lubricating properties of o il decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the engine oil should even be changed
mo re frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay be low freezing point for long periods.
Detergent addit ives in the oi l wi ll make fresh oil look dark after the
engine has been running for a short t ime. This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oi l that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to fai lure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner 's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Serv ice or Repair Orders that all scheduled maintenance
was performed in a time ly manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the lif e of the engine. Typically,
engines with a specified break- in period (see~
page 251) consume
more oil during the break-in period than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the ox idation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil leve l warning symbol in the instrument
cl uster lights up, you should chec k the oil level as soon as possible
with the oil dipstick~ page 283. Top off the oil at your earliest
convenience ~
page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Working in the engine
compartment" on
page 279.

Before you c heck a nythi ng in the eng ine compartment ,
always read and heed all WARNINGS~ & in "Working in
the e ngi ne comp art ment" on
page 279.
- Read t he bra ke flu id level from the bra ke fluid reservoir
~ page 289, fig . 212. The brake flu id level must be
between the " MIN" and " MAX" mar kings.
The brake fluid reservoir is locate d at the rear pa rtition of the engine
compartmen t on the left s ide=>
page 280 .
The f luid leve l may drop slightly after some time d ue to the auto ­
m atic a dju stment of t he b rake pads. This is not c ause for ala rm.
If the brake flu id level falls
considerably be low the "M IN" mark, the
brake warni ng/ind icator light (U .S. models :
BRAKE, Canadia n mo dels:
(0) ) will come on=> page 18 and=> page 26. Do not continue to
operate t he vehicle. The complete brake system sho uld be thoroug hly
chec ked by an au thor ized A ud i d eale r or othe r qualified fac ility and
the cause corrected.
If the brake fluid level is too low, the brake
Vehicle OP-eration
warning/ind icator light will illum inate . Contact an au thoriz ed Aud i

immediately .•
Changing brake fluid
H av e the b rake fluid chang ed by an expe rie nc ed t echni ­
CJ an.
B ra ke flui d abso rb s moi stur e from the air. If the wa te r c on ten t in t he
brake fl uid is too high, corros ion in the b rake system may res ult after
a pe riod of time. The boili ng po int of the brak e flu id will also decrea se
co nsiderab ly and decrease brak ing perfo rmance.
Th erefore, the brake f lui d m ust be c hanged
every two years . Always
use new brake fluid w hich conforms to Fede ral Motor Veh icle Stan ­
dard "F MVSS 1 16 DOT 4" .
Th e br ake f luid reserv oir can be diffi cult to rea ch, there fore, we
recommend that you have the brake fluid changed by your authori zed
Audi dealer . Your deal er h as th e correc t tools, the rig ht bra ke flui d
and the know-how to do th is for you.
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the rea ch of children!
• Brake
failure can result from old or inappropriate brake fluid .
Observe these precaution s:
- Use only b rake fluid that meets SAE specification
J 1703 and
conforms to Federa l Motor Vehicle Standard 116. Alway s check
with you r authorized Audi dealer to make sure you are using
the correct brake fluid. The corre ct type of brake fluid is also
indicated on the brake fluid rese rvoir.
- The brake fluid must be new . Heavy use of the brakes can
c ause a vapor lo ck if the brake fluid is left in the system too
long . Thi s can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident .

mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating condit ions, the battery in your Aud i does not
need any maintenance. With
high outside temperatures or long daily
drives we recommend that you have the electrolyte level checked by
a service facility. The electrolyte level should also be checked each
time the battery is charged~
page 292.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 211.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected aga in. To
prevent this, the battery should only be disconnected from the
vehicle electrical system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period~
page 249.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
power seat adjustment, may not be available. The convenience func­
tions will be available again when you turn on the ign ition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are used more often .
Avoid unnecessary power consumpt ion, particu larly in city traffic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before w inter sets in
=> page 292. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longe r.
(I] Tips
If your veh icle is left standing for several weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced.•
