Brakes
New brake pads
-
N ew brake pads do not achieve their fu ll brak­
ing effect d urin g the first
400 km. They must
be "broken i n" first. However, yo u can com­
pensate for the slightly reduced braking force
by pressing fi rmly on t he brake pedal. Avo id
heavy brak ing dur ing the break- in period.
Wear
Brake pad
wear is largely dependent on the
way the vehicle is dr iven and on operati ng
condit io ns. This is especially true if you are
driv ing frequent ly in t he ci ty and o n curves or
with a spor ty d rivi ng s tyle.
Operating noise
Noises may occur when bra king depending on
the speed , braking force and outside condi­
t ions such as tempe rature and hum id ity.
Effect of water and road salt
In certa in situations, for examp le after dr iv ing
t hr ough water, in heavy rain, after overnight
condensation or after was hing your car, the
braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be "d rie d" first with a few carefu l
brake applicat ions .
At highe r speeds and with the winds hield wip­
ers tu rned on, the brake pads press against
the b rake ro to rs fo r a short a mount of t ime .
T h is act ion which is not felt by the d river hap­
pen s at reg ular i nte rvals an d facilit ates a bet­

T he bra king effect can a lso be redu ced if you
are dr iv ing o n sal ted roads a nd you do not a p­
ply the br akes fo r long periods of time. The

Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake ro­
tors and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the
brake rotors and pads~,& .
Brake system malfunction
if you notice that the brake pedal t ravel has
suddenly gotten larger, then a brake circuit
may have failed . Drive to you r authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary .
Low brake fluid level
When the brake fluid level is low, ma lfunc­
tions in the brake system may occur . The
brake fluid level is electronically monitored.
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the eng ine is running.
A WARNING
-You should on ly perform braking maneu­
vers to clean the brakes when the road condit ions perm it . Never put others on
the road at risk -never forget the risk of
acc idents!
- On steep slopes, reduce the speed and
select a lower gear or lower selector lev­
er posi tion. Drive as little as possible
wh ile pressing the bra ke peda l and avoid
putt ing your left foot on the brake pedal
whi le driving. This could ca use the brakes
to overheat and impair the efficiency of
the brakes.
- Do not let the brakes "grind" by always
keeping yo ur foot on the brake peda l.
Smart Technolog y 191
This can cause the brakes to overheat in-,
crease wear and increase braking dis­
tance unnecessar ily.
- Certain weather and operating condi­
tions such as driving through water, driv­
ing in heavy rain or driving after washing
your veh icle can impa ir the effectiveness
of the brakes. In the winter, ice may
bui ld up on the brake pads, rotors and
drums . Check these components by brak­
ing caref ully. App lying the brakes care­
fu lly several times dries the brakes and
removes ice build-up .
- The effic iency of the brakes can also be
impaired by driving for long stretches on
roads covered with salt without using the
brakes. You can remove salt deposits
from the brake rotors and pads by care­
fully applying the brakes several times.
- If the front spoiler is damaged or you in­
stall another spoiler, make sure the front
wheel brakes are ventilated properly.
Otherwise, the brake system could over­ heat, wh ich reduces their effectiveness .
- Failure of a brake circuit impa irs braking
performance, wh ich increases braking
d istance . Avoid driving the vehicle and
have it towed it to the nearest author­
i z ed Audi dealer or authorized Audi Serv­
ice Facility.
- Do not let your veh icle roll w ith the en­
gine switched off under any circumstan­
ces .
- If the brak e booster is not working, you
wi ll have to press much harder on the
brake peda l to compensate for the lack
of the booster.
(D Note
-Never let the brakes "rub" by pressing
the pedal lightly when braking is not
really necessary. This causes the brakes
to overheat and increases braking dis­
tance and causes wear.
- Before driving on a long stretch with
steep s lopes, reduce your speed and shift
to the next lower gear This makes use of
the engine brak ing effect and relieves ..,.

the brakes. If you need to brake addition­
ally, brake in intervals and not continu­
ously.
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much
more force then norma l.
- If you retrofit your vehicle with a front
spoiler, wheel covers or similar items,
make sure that the air flow to the front
wheels is not interrupted. Otherwise the
brake system can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
The vehicle still has full steering functionality if the power steering fai ls or when the engine
is stopped (towing). To steer, you must apply
much more force than usual.
Indicator lights and messages

All wheel drive
(quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels are pow­
ered.
General information
In all whee l drive, the driving power is divided
between a ll four wheels . This happens auto­
matically depending on your driving behavior
as well as the current road conditions. Refer
to
¢ page 188, Electronic stabilization con­
trol (£SC) .
The all wheel drive concept is designed for
high engine power. Your vehicle is exception­
ally powerful and has excellent driving charac­
teristics both under normal driving cond itions
and on snow and ice . Always read and follow
safety p recaut ions

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 intained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaus t gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service
If you wou ld like to take your vehicle out of
service for a longer t ime, contact your author­
ized Audi dealer or qualified repair facility.
They will advise you of important measures,
such as corrosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery
¢ page 223.
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
personal driving style
- operating conditions
- technical limitations
If you ant ic ipate what you need to do next and
drive econom ically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION 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
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less. Let the vehicle coast
whenever possible -for example when you see
that the next traffic light is red.
Avoid full throttle '
Driving at moderate speeds saves fuel and
improves your mileage.
.,. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fue l consump­
tion, engine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emissions and en­
gine noise increase disproportionate ly at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption wi ll
be reduced by one half. Never drive faster

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
a n d driving instr uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns .
Trailer towin g 201
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Alw ays use saf ety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra iler lights must meet all reg ulations . Be
su re to check with your Audi dea ler fo r cor re ct
wir ing, swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must i nsta ll ext ended mir rors . It is important
t h at you
always have clea r vis ion to the rear .
.8, WARNING
-
Afte r removing the trailer hit ch, do no t
s tore i t in yo ur vehicle . In case of sudden
b raking, the h itch cou ld fly forwar d an d in­
ju re you or yo ur passengers .
Operating instructions
Maximum trailer weight
A tra ile r fo r you r vehicle is limited to a ty pical
cl ass 1 or class 2 tra ile r.
Trailer load distribution
B e sure the loa d in the tr aile r is held secure ly
i n place to p reven t it from shift ing forw ard,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
¢ &. in Driving instru ctions on page 20 2.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system's
perfo rmance is up to the additional load .
Make sure that the coo ling syst em has enough
f lui d.
Tire pressure
When towing a trailer , inflate the tires of your
vehicle to t he cold tire pressure listed under .,..

202 Trailer towing
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trai ler and t ire manufac ­
turers' specif ications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be espec ially car efu l when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed.
.. Always apply brakes early .
.. Monitor the temperature gauge.
Weight distribution
Towing a loa ded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances . Whenever possi- ble,
transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tong ue load requirements and vehicle loading
considerations.
Speed
T he higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed . Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge~ page 12
must be observed carefu lly. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the d isplay turn on .
For more information about indicator lights,
refer to. ~

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.

A WARNING
- To reduce the risk of personal injury
nev­
er touch the radiator fan.
- The auxiliary electr ic fan is temperature
contro lled and can switch on sudden ly

by an authorized Audi dealer or other quali ­
fied facility and the cause corrected. If the
brake fluid level is too low, the brake warning/
indicator ligh t will illuminate. Contact an au­
thorized Audi dea ler
immediately.
Changing brake fluid
Have the broke fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air. If
the water content in the brake f luid is too
high, corrosion in the brake system may result
after a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance.
T he refo re, the brake fluid must be changed
every two years. Always use new brake fluid
wh ich conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
T he brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the b rake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you .
A WARNING
---Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from o ld or inap·
propriate brake flu id. Observe these pre·
