switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -loc k brak ing s ystem (ABS )
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is helping you to brake the vehicle.
B rake ass is t system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Elect ronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot ove rcome
t he laws of physics. This is espec ia lly im ­
portant on slippery or wet roads.
If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligen t technolog y 151
to take risks. Doing so will increase the
risk of a loss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot preven t coll i­
sions.
- Always ac celera te with spe cial care on
even, smooth s urfaces su ch as those th at
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems described are working.

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 .,.

down continuously. Pump the brakes at inter ­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Under certain conditions, for examp le, when
d riving through water or ve ry heavy rain, or
even after washing your vehicle , the bra king
effect can be reduced due to moisture (o r in
freezing conditions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the b rakes can be reduced
when the vehicle is driven on a salt -covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake
q .&. .
Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed

Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid

Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection

aware of when changing a tire?.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. 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 braking
efficiency.
- Do not "ride the brakes" by rest ing 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 operat ing
conditions such as passing through wa­
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the b rakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
fu l brake applications.
- Driving for an extended period of time on salt-covered roads without using your brakes can a lso 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 a ir

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometre s):
.,. Do not use full throttle .
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
.. Avoid hig h engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
.. Speeds ca n gradually be increased to th e
maximum pe rm iss ib le road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds
when it is cold . T hi s applies whether the
transmission is in N (Neutral) o r in gear.
After the break- in period
.. Do not exceed max imum eng ine speed un­
der any circumstances .
.. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
<::;> page 10.
During the first few hours of driving, the en­
g ine 's inter na l friction is higher than later
when all the moving pa rts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable ex tent o n the way t he
ve hicl e is driven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engine speeds a re auto­
mat ic al ly reduced. However, t hese RPM-

limits were programmed for an eng ine
well run-in, not a new eng ine.
@ For the sake of the environment
Do not d rive wi th unnecessar ily h igh en­
gine speeds -upshifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly carefu l for the first 350 miles
(S00 ki lometres) after fitting .
A WARNING
-New tires tend to be s lippery and must a l-
so be "broken-in". Be s ure to remembe r
this dur ing t he firs t 3S 0 m iles (500 kilo­
me tres) . Brake gent ly . Avo id following
closely behind other vehicles or other sit­ uations that m ight require sudden, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 miles
(400 kilometres) after they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&..
D uring the break-in period, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very h igh speeds or, for
example, on mou nta in passes.
A WARNING
Until t hey develop the maximum "bite" fo r
best stopping power, the s urfaces on new
b rake pads requ ire some "brea king- in" dur­
in g the initial 10 0 to 150 miles (15 0 to
20 0 kilome tres) of normal c ity dr iv ing. Yo u
can compensate for this by press ing the
b rake peda l more f irm ly . This applies
whenever new pads are installed.

160 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 176,
Fuel supply .
.,. Never run the tank down all the way to
empty .
.,. Never put too much motor o il in your en-
gine ¢
page 185, Adding engine oil 'l::r. .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
u p" dev ice buil t into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of t he pollu tan ts in the exha ust gas be­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critica lly
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
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
rustproofing 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 185.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenan ce booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maxi -
mum speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing . How
often this is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle paint, the more lasting their destructive ef­
fects wi ll be .
High tempera tures, as from expos ure to in­
tense sunlight, intensify the corrosive e ffect
particularly when humidity is high as well.
Under certa in ci rc u mstances,
we ekly washing
may be necessary. Unde r othe r cond it ions, a
monthly washing and waxing may be ade ­
quate.
After the winter, the unders ide of the vehicle
sho uld be thoro ughly washed p re ferab ly in a
pro fessional ca r wash.
A WARNING ~
A lways read and heed all WARNINGS and
the information
c::> page 164.

~ Wipe the windows dry with a clean piece of
cloth or kitchen paper towel.
The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mir­
rors.
The windows must not be cleaned with insect
remover or wax since these can interfere with
the function of the windshield wiper blades
(chatter).
Oil, grease or silicone residue can be removed
with
glass cleaner or silicone remover. How­
ever, wax residue requires the use of a special­
ly formulated solvent. Please contact your
Audi dealer for advice on safe products for
wax removal.
Windows should also be cleaned on the inside
at regular intervals.
Never dry windows with the same chamois
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vision through
the windows.
A WARNING
-The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Always read and heed all WARNINGS and
other information
¢page 164.
(D Note
-Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di-

The wheels also have to be cleaned.
~ Always include the hub caps and wheel rims
when washing your vehicle to remove road
dirt, salt sprays and brake dust.
If necessary, use a commercial wheel cleaner
to remove accumulated brake dust.
The wheel rims are easier to keep clean if they
are regu larly coated with liquid wax.

Cast (light) alloy wheels
Applies to vehicles: with Cast alloy wheels
Cast (light) alloy wheels require special care.
~ Wash the wheels with a sponge or hose
brush every other week.
~ For deep cleaning afterwards, use only a
dedicated
acid-free cast alloy wheel cleaner .
~ Rub a coat of liquid wax onto the rims every
three month. Be sure to reach and treat all
parts of the rim.
To preserve the decorative appearance of the
cast alloy wheels, some special care is neces­ sary. In addition to road dirt and salt, brake
dust is also corrosiv e. If left on for too long,
brake dust can cause pitting.
