have fai led .
- Dur ing initialization the sys tem has detect ­
ed more than 4 wheels on the vehicle , for
examp le w hile d riving next to another car
w ith a t ire pressure monitoring system.
- Audi rep lacement parts were not used .
- If snow cha ins a re being used, system func-
tion can be compromised due to the shie ld ­
ing properties of the chains.
- The tire pressu re monitoring system may
not be avai lab le because of a radio malfunc­
tion.
- T ransmitters with the same freq uency, such
as radio headphones in the vehicle or radio
equ ipment, can cause a temporary disrup­
tion of the system through excessive elec­
tromagnet ic fie lds .
- Eliminate the interference if yo u can and
then proceed as follows: Turn off the eng ine
for 20 minutes. Then drive another 10 mi­
nutes. If the war ning light comes on again,
you shou ld contact yo ur autho rized Aud i

Braking
New brake pads
During the firs t 250 miles (4 00 km), new
b rake pads do not possess their f ull braking
effect, they have to be "broken in" first. The
d istance can be ten times longer in ve hicles
with ceramic brakes *. Yo u can compensate f or
this slightly reduced b rak ing power by push­
in g harder on the b rake pedal. Avoid heavy
br ak ing loads during the b reak -in period.
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wear, depending largely on operat­
ing conditi ons and dr iv ing habits
c:> & . On ve­
hi cles that are either driven mostly in stop­
a n d-go ci ty traffic o r are d riven ha rd, the
b rake pads should be checked by you r auth or­
iz ed A udi dealer more o ften than specifie d in
the
Warranty & Maintenan ce booklet . Fail ure
to have your b rake pads inspected can res ult
i n re duced b rake performance.
O n steep slo pes, you shou ld use the b ra kin g
effec t of the eng ine. Th is w ay, yo u prevent un­
n ecessa ry wea r on the bra ke system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously. P ump the brakes at inte r­
va ls.
Moisture or road salt
A t speed s above 70 mph ( 110 k m/h) and wit h
the windshield wipe rs swi tched
on (at le ast in ­
terval stage 4), the bra ke pads are br iefly a p­
p lied against the bra ke discs. T his occ urs at
regu lar intervals witho ut the driver noticing
and prov ides for better brake response time
u nder wet condit io ns.
Unde r ce rtain conditions, for examp le, w hen
driving thr ough water or ve ry heavy rain, or
even after was hing yo ur vehicle, the brak ing
effect ca n be red uced d ue to moisture (or in
freezing conditions ice) on the brake pads. A
few ca utious brake applicat ions should d ry off
t he bra ke pads o r rem ove any ice coa tings.
The effective ness of the brakes can be reduced
when the vehicle is dr iven o n a salt-covered
Intelligent technology 153
road and the b ra kes are no t used . Li kewise,
yo u clean off accu mulated salt coatin g from
brake d iscs and pads with a few cautio us ap ­
plications of t he brake
c:> & .
Corrosion
The re may be a tendency for di rt to build up
on the brake pads and cor ros ion to form on
the discs if t he car is not driven regu la rly or
on ly for short trips w ith litt le use of the
brakes.
If the brakes are not use d frequently, o r if cor­
r os ion has formed on the discs, it is adv isa ble
to clean off the pads and d iscs by braking
firmly a few times from a moderately high
speed
c:> & .
Faults in the brake system
If you shou ld not ice a sudden in crease i n
brake pedal trave l, t hen one of the two brake
c ir cuits may have fa iled. Dr ive immediately to
the nearest qualified wor kshop to have the
damage repaired . Dr ive at reduced speed on

Low brake fluid level
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored elect ro nica lly.
Brake power assist unit
T he bra ke power assist unit increases the
pressure that you generate w ith the brake
pedal. It work s only when the engine is run­
ning.
Brake lining wear status
B ra ke lining wear may be che cke d by visual in ­
s p ection of t he condition of the bra ke pads
th ro ugh the open ings in the wheel. If neces ­
sary, the w hee l may be removed fo r thi s i n­

A WARNING
- You should perform braking mane uvers
f o r th e purpos e of cleaning the brake
s ys tem only if roa d condit ions permit.

154 Intelligent technology
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or hold the pedal down
too long or too often. This could cause
the brakes to get hot and diminish brak­ ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few cau­
tious brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
- 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 effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
braking capability, resulting in increased
stopping distance. Avoid driving the vehi­
cle and have it towed to the nearest au­
thorized Audi dealer or qualified work­
shop.
- 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.
Power steering
When the engine is running , power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehi­
cle with little physical effort.
If the engine is not running, the power steer­
ing system is also not working . In this case ,
you will find it extremely difficult to turn the
steering wheel.
If you turn the steering fully to the left or
right when the vehicle is stationary, you place
a very heavy load on the power steering sys­
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine idle speed.
(D Note
Do not hold the steering turned fully to
the left or right for more than 10 seconds
when the engine is running . There is a risk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be able
to steer the vehicle. However, you will re­
quire more effort to do so .
- If the power steering system has a leak
or is defective, you should immediately
contact a qualified workshop .
- The power steering system requires a
special hydraulic fluid. The power steer­
ing fluid reservoir is located in the en­
gine compartment. The correct hydraulic
fluid level is important for proper opera­
tion of the power steering system. The
power steering fluid level is checked ac­
cording to the Audi maintenance service
schedule.

158 Driving and en vi ro nm ent
Driving and
environment
Break-in period
A new vehicle must be broken in, and the break-in per iod should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 miles (1,000 km) and do not exceed the
maximum eng ine speed of 6,000 rpm You
must also not use fu ll acce lerat ion between
600 and 1,200 mi les (1,000 to 2,000 km).
F rom 1,200 to 1,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en­
gine speed to 8,250 rpm for brief periods.
During the first ho urs of operation, there is
g reater friction in the engine and the trans­
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic ­
u lar ly when the engine is cold, yo u reduce en ­
g ine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low. Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov­
erned automatically.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body .
- Do not drive faster than wa lking speed.
.&_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re­
sto re the full braking effect.
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys­
tem can be severe ly damaged by dr iv ing
through water.
@ Tips
- Check the depth of the water before d riv­
ing through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i­
cle, otherwise you will destroy the catalyt ic
converter.
Never run the fuel tank completely dry; their­
regular fuel supply could cause misfires . This
allows unburned fuel into the exhaust system,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
areas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
