& WARNING
-Never let the vehicle roll to a stop with
the engine shut
off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.
Servotronic ® -
advanced power
steering system
-
The power steering systems use the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic ® power steering
system senses the road speed and e lectroni
cally adjusts power ass istance to provide com
fortable and safe steering response exactly matched to the veh icle speed.
Power steering wi ll not work if the engine is
off. As a resu lt, the steering whee l wi ll be hard
to turn.
The power steering fluid level is checked dur ing the scheduled maintenance services.
(D Note
I f there is an electronic malfunct ion, ser
votronic
will sti ll function like a conven
tional 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 steer ing whee l at low speeds (for examp le
when parking), -more effo rt will be re
qui red than usual.
- Be awa re of the different than usual
steering response and adjust your stee r
i ng fo rce accord ingly.
- Have the p roblem checked and set right
by an Aud i dealer as soon as possib le .

(D Tips
-When the engine is running, never ho ld
the steering wheel turned all the way to
the right or to the left for longer than 15
seconds. The power steering pump will
overheat the hydrau lic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system.
- If the powe r stee ring system should fa il
entire ly, o r if the e ngine is not run ning
(for example, wh ile be ing towed), you
w ill still be able to stee r the veh icle.
However,
considerably more effor t will
be required to do so .
- If the power stee ring system sho uld
have a lea k, or is not functioning proper
ly, contact your authorized A udi dealer
immediately.
- The power steering system req uires a
specially formu lated hydra ulic fluid. The
power steering fluid reservoir is located
in the engine compartment
Q page 221.
The correct fluid level in the reservoir is
important for proper functioning of the
powe r stee ring.

Only if the level of the oil is at or below the min imum mark -and no oil that expressly
conforms to Audi oil standard VW 502 00
specifications is available -may you top off
with a high quality engine oil, preferably syn
thetic -based, that meets ACEA A3 or API SM
specifications, but even then, only in viscosity
grades SAE SW-40, SAE SW-30, or SAE
OW-40. However, during the entire time be
tween oil change intervals, never top off with
more than a total of 0.5 qt/liter engine oil
that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa.com or
www.audicanada.ca. Here you will also find a current list of oils (manufacturers, brand
names etc .) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter
vals is so very important because the lubricat ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently.
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.
Detergent additives in the oil will make fresh
oil look dark after the engine has been run-
Checking and filling 223
ning for a short time. 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 oil
that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte
nance 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 Service or Re
pair Orders that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving ports .
In order to provide effective lubrication and
cooling of internal engine components, all in
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 194) consume 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 oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida-
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump-
tion may increase over time until replacement
of worn components may become necessary. ..,.
