• Press the sw itch Q fig . 87 to tu rn sport set-
t ing on or off.
Aud i magnetic ride is an electronically con­
trolled damping system. This chassis system
assists the dr iver by adapting to the particular
situation through imperceptible control proc­
esses. The
da mping provides individua l modu­
lation of damping forces. For example, with
damping characteristics set to provide greater
comfort, damping is set somewhat harder for
a brief period only
as required, when rounding
a curve and when braking.

Braking
General information
What affects braking efficiency?
Operating conditions and d riving habit s
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat­
i ng cond itions and dr iv ing habits
c:> & . On
ve hicles that a re e ithe r dr iven mostly in stop­
and-go city traffic o r a re driven ha rd , the
b rake pads should be checked by yo ur auth or­
iz ed A udi dealer more often th an specifie d in
the
Warranty & Maintenance booklet . Fail ure
to have your b ra ke pads inspected can res ult
in red uced b rake performance.
O n steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the engine . This way, yo u preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously . P u mp the brakes at inter­
va ls.
N oises may occur w hen braking depending on
the speed, bra king force and outside condi ­
tions s uch as temperature and h umidity.
Moisture or road salt
Unde r cert a in co ndi tions, for examp le, w hen
d riving through wate r or ve ry heavy rain , or
even after washing yo ur vehicle , the braking effect can be
reduced due to mois ture (or in
freez ing cond itions ice) on the brake pads. A
f ew cautio us brake applications s hou ld dry off
the brake pads or remove any ice coatings.
T he effec tiveness of the brakes can be red uce d
whe n the vehicle is d riven on a sa lt -covered
road and the b rakes are not used . Likewise,
yo u clean off acc umulated salt coat ing from
brake d iscs and pads with a few cautio us ap­
plicat ions o f th e b rake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
t h e d iscs if the car is not driven regu larly or
o n ly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads a nd d iscs by braking
firmly a few times from a moderately h igh
s p eed

A WARNING
-You should perform brak ing maneuvers
for the purpose of cleaning the brake
system only if road cond it ions permit .
Other road users must not be put at r isk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transm iss ion into a lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing throug h wa­
ter, driving in heavy rai n or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, lini ngs,
discs and d rums. Carefully apply brakes
f or a test . B rakes wi ll dry and ice coat­
ings wi ll be cleaned
off after a few ca re ­
ful brake applications.
- Driv ing for an ex tended pe riod of time on
salt -covered roa ds without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system could
overheat reducing the eff ectiveness of
the ent ire brake system.
- Failure of one bra ke c ircuit will impair
the brak ing capability resulting in an in­
cr eased stopp ing distan ce. Avoid dr iv ing
the ve hicle and have it towed to the near­
est Aud i dea le r or q ualified workshop .
- Never le t the vehicle ro ll to a stop w ith
the engine shu t off.
Int ellig ent technolog y 145
-If the brake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electro-mechanical
power assist
The ele ctro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to veh icle speed.
The powe r steering system assists the driver
so that he can steer the vehicle with reduced
physical effort.
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
-
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force tha t is no
l onger proportionate to the vehicle speed.
This is most noticeable when t urning the
steering wheel at low speeds (for example
when parking), - more effort w ill be re­
quired than usual.
- 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 authori zed Aud i dea ler as soon as
possible.
- If a steering malfunction occurs, th is is
signa led w ith the

150 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline¢ page 160,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much moto r o il in yo ur eng ine
¢ page 169, Adding engine oil ~-
.. Never try to push- or tow-st art you r vehicle.
The catalytic co nverter is an efficient "clean­
u p" dev ice built into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollutan ts in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engi ne.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 169.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.

152 Driving and en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
"'Try and keep well below your car 's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine no ise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never dr ive faster
than the posted speed limit and weather con­
d itions permit .
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 veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine 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 s tarting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . Howeve r, 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 while the engine
is sti ll warming up.
([) Note
Do not leave engine idling unattended af ­
ter starting . If warning lights should 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 ve hicle serviced at reg ular in ter -
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensure that it runs p rop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its val ue, it also affects
fuel con sum p­
tion .
Check your oil e ach time you fill your t ank .
The amount of o il used is related to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven.
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 cons umption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacturer.
- Do not alte r or remove any device, such
a s hea t sh ie lds, switches, ig nition w ires,
valves, which are designed to protec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .
