Introduction
Applies to vehicles: w ith Driver information display
General notes
The driver information display inside the instrument
cluster provides you, the driver, with important informa­ tion.

c lu st er: ce nte r dis play
The driver information display is located in the center of the instru­
ment
cluster:::> fig. 10.
The driver information system updates important information in the center display in clear view of the driver . In an easy to understand
format, the display tel ls you how your vehicle is functioning
at th e
c urr ent m om ent .
For example, the display can te ll you how many
miles (ki lometers) you can still drive until it is time to bring your
vehic le to your authorized Audi dealer for a scheduled Maintenance
Service. This feature helps preventing costly repairs. It is just one of
many different items o f information available for recall. The display also gives you a "status report" whenever the
sou
nd sys te m and
n av igatio n
systems are being used.
Detailed instructions for operating the Aud i Naviga tion System* are
provided in separate manuals.
[ i] Tips
If your vehic le has an automatic transmission, the various display
contents will appear only after you have moved the selector lever
into
R , D or S. •

& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i] Tips
• If ABS is not functioning properly, a warning light will come on.
See~ page 21.
• If a fault occurs in the ABS , the EDL is also not functioning. This
is indicated by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve a shorter stopping distance . If the driver
presses the brake pedal very quickly, the brake assistant automati ­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking. You should then keep the brake pedal pressed
until the vehicle has braked to the required speed. The brake assis ­
tant switches itself off as soon as you release the brake pedal.
The brake assistant will not be operative if there is a malfunction in
the ABS.

ment Safety first
Vehicle operation
& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so
always maintain a safe speed. •
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort. Your Audi is equipped with the electronically controlled
Servotronic® advanced power steering system. It adjusts
the degree of steering assistance to the roadspeed.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result, the
steering wheel will be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services.
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power steering system, providing a constant
steering support force that is no longer proportionate to the vehicle
speed . This is most noticeable when turning the steering wheel at
low speeds (for example when parking), -more effort will be
required than usual.

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 prov ide effect ive lubrication and cool ing of in ternal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to engine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specified break -in period
(see ~ page 243) consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under norma l condit ions, the rate of o il consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at whic h the engine is operated, t he amb ient te mperature and road
conditions. Further factors are the amount of oil dilution from water
condensatio n or fuel residue and t he oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
t ion may increase over time until rep laceme nt of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regu lar and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrument
cluster ~ lights up, you should check the oil level as soon as
possible
with the oil dipstick ~ page 277 . Top off the o il at your
earl iest
convenience~ page 278.
& WARNING
Bef ore you che ck anything in the eng ine comp artment , alway s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 27 3.
0 Note
Driving with an insuff ic ient oil level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pres sure warning displ ay "e:7: is n ot an indi cator of the oil
level . Do not rel y on it. Instead, check the oil level in your engine at
regular inter vals, preferably ea ch time you refuel , and al way s before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that t he accurate measurement of oil consumptio n requ ires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil cons umpt ion accurately. •

Important considerations for you and your
vehicle
T he increasing use of elec tronics, sophisticated fue l injection and
emission con trol systems, and t he gene rally increasing tec hn ical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repai rs which can be carried ou t by vehic le
owners.
Also , safety and environmental concerns p lace very strict
limits on the nature of repairs and adjustments to engine and trans ­
m iss ion parts whic h an owne r can perform.
Maintenance , adjustments and repairs usua lly require special tools ,
t es ting dev ices a nd othe r eq uipment availab le to s pec ial ly t rai ned
workshop personne l in order to assure proper performance , reli ­
abil ity and safe ty of the vehicle and its many sy stems .
Im proper maintena nce, adjustments and repairs can impa ir the
operation and reliability of your vehicle and even void your vehicle
wa rranty. T here fore, proof o f servic ing in acc orda nce with the main­
tenance schedule may be a condition for upholding a possib le
warranty cla im made with in t he war ran ty per iod .
Above all, operationa l safety can be adversely affected, creating
unnecessary risks for you and your passengers.
I f in doubt about any servicing, have it do ne by your auth orized Audi
dea ler or any other properly equipped and qua lified workshop . We
