Braking
General information
What affects braking efficiency?
Ope rating cond itions and driving habits
The brakes on today's automobiles a re still
subject to wear, depe nd ing largely on operat ­
ing condit ions and driving hab its
c:> .&,. . On
vehicles that are either driven most ly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be checked by yo ur au thor­
ized Audi dealer more often than specified in
the
Warr anty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. T his way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes .,.

overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dealer or qualified workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
The degree of power assist is electronically
matched to vehicle speed.
The power steer ing system ass ists the driver
so that he can stee r the veh icle w ith red uced
phys ica l effort.
Power steering w ill not work if the engine is
off. As a result, the steering wheel w ill be hard
to turn.
& WARNING
If the system develops a prob lem, you
must seek qualified professional assis­
tance.
(D Note
-
If there is an electronic malfunct ion, ser­
votronic
wi ll 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 wheel at low speeds (for example
when parking), -more effort will be re­
quired than usual.
Int ellig ent technolog y 155
-Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authorized Audi dea ler as soon as
possible.
- If a steering malfunction occurs, this is
signaled with the,~ , or .• indicator
lights and a warn ing tone, see.
(D Tips
- If the power steering system sho uld fail,
or if the engine is not running (for exam­
ple, while being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately.

en.
General information
With a ll-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depend ing on your driving style and the road
conditions at the time. See also
c::> page 1 SO.
The all-whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions

Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all fou r
wheels. See also c::> page 211, Winter tires. ..,_

162 Driving and en vironm ent
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not driv­
ing the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic lights that have
l ong wa its on red . Turning the engine off fo r
just 30-40 seconds saves more fue l than is
burned starti ng the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ab ility to
hold its value, it also affects
fuel con sump­
tion .
Check you r oil ea ch time you fill you r tan k.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved
by the manufacturer.
- Do not alter or remove any device, such
as heat sh ie lds, switches, ignit ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road, the mileage improves
to 12 MPG (20 l/100 km). It w ill take the

174 Cleaning and protection
• Once the stain is no longer visib le, use a
soft dry cloth or tissue to soak up the mois ­
ture.
Do not use leather cleaning products on Al ­
cantara .
You may use a suitable shampoo fo r remov ing
d ust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface. If the ca r is
l eft standing i n the sun fo r long periods, the
A lcantara should be protected against direc t
sunlight to prevent it from fading. Slight co lor
variations will deve lop in normal use and are
not an indication of material deterioration.
{[) Note
-Never use chemical solvents (e.g . lighter
fl uid, turpentine), waxes, shoe polis h or
similar products on Alcantara ® surfaces.
- To avoid damage, have stubborn stains removed by a commercial cleaning spe­
cia list.
- Do not use br ushes, stiff sponges or sim­
ilarly abrasive cleaning aids.
Safety belts
Only well -maintained safety belts work relia ­
bly when needed .
Heavily soiled safety belts may no t retr act
p roperly.
• Keep be lts clean.
• Fo r cl eaning, use a m ild soap and wate r sol­
u tion. Let be lts dry thoro ughly and away
from direct sunlight .
• Do not a llow inertia reel safety be lts to re­
tract before they are completely dry .
• Check the condition of your safety belts
reg­
ularly.
.&_ WARNING
Damaged safety belts can break in a crash.
1l Use o nly the co rrect cleaning so lu tions. Never use gas­
o line or d iese l fue l.
-Anyth ing that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequate ly pro­
tected in an accident.
- Safety belt performance depends on cor­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clean ing agents,
b leach or dyes. They have co rrosive prop­
erties which wea ken the webb ing.
- When clean ing your safety be lts, inspect
them for damage . If you discover dam­
age, see your Audi dealer.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
T he eng ine in your Aud i is a soph ist icated
powerplant that was built to exact ing spec ifi­
cat ions . T his engine needs the right kind of
engine oil that meets specifications regard ing
quality and viscosity so that it can run
smooth ly and reliably . Choosing the right o il
and changing oil within the time and mileage
i ntervals printed in your vehicle's Warranty

Maintenance booklet matters a lot more to­
day tha n it did years ago. Audi has developed
a spec ia l quality standard for engine oil that
will help assure that you r vehicle's engine w ill

t ion.
Modern engine l ubr ication has taken a q uan­
tum leap in the last few years. Many synthet ic

184 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty

deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led 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.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::;, page 159) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
II lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 185. Top off the
o il at your earliest conven ience
c::;, page 185 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS
c::;, .& in Working in the engine
comportment on page 180.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at regular intervals, pr ef­
erably ea ch time you refu el, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.
