Warnings
App lies to vehicles: with Audi pre sense front or Audi
adaptive cruise control
Fig. 94 Instrument cluster: approac h warning
The system recognizes various dangerous sit­
uations:
- Vehicles with adaptive cruise control : The
distance warning occurs if you drive too
closely to the object ahead for a long period
of t ime. If the object ahead brakes strongly,
you would not be able to avoid a coll ision.
The indicator light . indicates this.
- The
approach warning occurs when an ob­
ject ahead is traveling mo re slowly or brakes
strongly. When this warning occurs, it may only be possible to avoid a collision by
swerving or braking strongly. The message
Audi pre sense. Distance ¢ fig . 94 and a
warning tone will warn you about the dan­ ger. For vehicles with adaptive cruise con­
trol, the. indicator light also turns on.
If you do not react enough or not at all to a
dangerous situation that was detected by the
system, pre sense front provides ass istance by
applying the brakes.
- If a collision is imminent, the system will
first provide an
acute warning by braking
sharply. You will also be made aware of the
danger by the instrument cluster display

lision. The message Audi pre sense -Input
also appears.
- At low driving speeds , pre sense front can
begin complete deceleration shortly before
a collision
ll .
- If pre sense front determines that you are
not braking strongly enough when a colli ­
sion is immin ent, it can increas e the braking
force.
A WARNING
- Pre sense front cannot overcome natural
physical laws. It is a system designed to
assist and it cannot prevent a collision .
The driver must always intervene. The
driver is always responsible for braking
at the correct time. Do not let the in­
creased safety provided tempt you into
taking risks. This could increase your risk
of a collision.
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensor does not al­
ways detect all objects . This increases
the risk of a collision.
- Pre sense front does not react to people
or animals or objects that are crossing
the vehicle's path or are difficult to de­
tect ¢
page 87, General Information.
-Reflective objects such as guard rails or
the entrance to a tunnel, heavy rain and
ice can affect the function of the radar
sensor and the system 's ability to detect
a collision risk .
- Lack of attention can lead to collisions,
other accidents and serious injuries. pre
sense front is an assistance system and
cannot prevent a collision by itself . The
driver must always intervene. The driver
is always responsible for braking at the
right time.
- Always pay attention to traffic, even
when pre sense front is switched on. Al-
ways be ready to intervene and take over
complete control of the vehicle whenever

A WARNING
- The vehicle can roll even when the en­
gine is sw itched off.
- Unintended vehicle movement can lead
to serious injuries.
- Never leave your vehicle with the engine running while in gear. If you must leave
your veh icle when the engine is running,
set the parking brake and move these­
lector lever to the P position.
- Power is still transferred to the wheels
when the engine is running at idle . To
prevent the vehicle from "c reeping", you
must keep your foot on the brake when
the engine is running and the se lector
lever is in the D, Sor R position or "tip­
tronic" mode is selected .
- Do not inadvertently press the accelera ­
tor peda l when the vehicle is stationary.
Otherwise the vehicle wi ll start to move
immed iate ly, even if the parking brake is
set. Th is could resu lt in a crash.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the engine is running.
- Never engage the R or P selector leve l
positions while dr iv ing. It could cause a
crash.
- Before driving down a steep slope, re­
duce your speed and shift into a lower
gear with "tiptronic". -
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill . Constant braking causes the
brakes to overheat and substantially re­
duces braking pe rformance, increases
b ra ki ng distance or causes complete fa il­
ure of the brake system.
- I f you must stop on an in cl ine, always
hold the vehicle in place with the foot
bra ke or parking brake to p reven t it from
rolling back .

- If the engine must run while you are
working in the eng ine compartment with
the hood open, make sure a gear is not
engaged. The selector lever must be
firmly in the

door is closed and dr iver's safety be lt is
fastened.
Hill descent control
Applies to veh icles: w ith S tronic transm iss io n
Hill descent control assists the driver when
driving down hills .
Hill descent contro l is activated when these­
lector lever is in the Dor 5 position and you
press the brake pedal. The transm ission auto­
matically selects a gear that is su itab le for the
incl ine. Hill descent cont ro l tries to ma inta in
t h e speed ac hieved at the t ime of b raking,
within physica l and tec hni cal limitations. If
may sti ll be necessary to ad just the speed
with the brakes . Because hill descent control
cannot shift down farther than 3rd gea r, it
may be necessary to sh ift into t iptronic mode
i n very steep areas . In this case, shift into 1st
or 2nd gear in t iptron ic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent contro l sw itches off once the h ill
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
¢ page 85, hill descent control is also activat ­
ed when the speed is set.
A WARNING
--
H ill descent control cannot overcome
physical lim itations, so it may not be ab le
to maintain a constant speed unde r a ll
conditions. A lways be ready to apply the
b rakes.

Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is insta lled by some vehi­
cle manufacturers to record data about crash ­
es so tha t it can be analy zed later. Crash data
recorders are also called "Event Data Record­
ers (EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your veh icle is not equipped with a crash data
recorder. However it does contain a var iety of
e lectronic control modules for various vehicle
systems such as eng ine funct ion, exhaust
treatment or airbags and safety belts .
These electron ic control modules record vehi­
cle data during normal driv ing for diagnosis
and repair purposes. The recording capab ility
of the electron ic control modules is lim ited to
data only- no sound is reco rded.
If t he control
mo dule detects a sys tem m alfu nction or other
change in sta tus, a very lim ited amount of da­
ta is recorded for an extreme ly sma ll period of
time . Data t hat is recorded in s uch a case may
include veh icle speed, driving direction, the
load on the brakes and head restraints and
performance in the event of an acc iden t or
other change in status . The stored data can
only be read o r down loaded w ith specia l dev i­
ces.
Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Cont rol (ESC) con­
tr ibutes to d river safety. It reduces the risk of
slipp ing and improves driving stability. ESC detects critical situations such as the veh
icle
oversteering and understeering or the whee ls
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torq ue.
Once the ESC is activated, the ind icator light
Bl blinks in the instrument cluster .
The following systems are integrated in the ESC:
Anti -lock braking s ystem (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle can still be steered even
during hard braking . App ly steady pressure to
the brake peda l. Do not pump the peda l. A
puls ing in the brake peda l ind icates that the
system is act ing to stabilize the ve hicle.
Brake assi st sy st e m
The brake assist system can decrease braking
distance .
It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You m ust press and hold the
brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sens it ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regu lation (ASR )
ASR reduces engine power when the drive
wheels begin sp inning and adapts the force to
the road conditions. This makes it easier to
sta rt , accelerate and dr ive up inclines .
Electronic differenti al lock (EDL )
The EDL brakes whee ls that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive *). This function is not ava ilable
at h igher speeds .
In extreme cases, EDL automatically sw itches
off to keep t he b rake on the braked wheel
from overheat ing. The ve hicle is still working
co rrect ly. EDL w ill switch o n aga in automat i­
ca lly when cond itions have ret urned to no r-

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.

Driving through water
on roads
Note the following to avoid vehicle damage
when driving 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.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
([) Note
Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- 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.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
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 gaso line¢ page 210,
Fuel supply .
.,. Never run the tank down all the way to emp-
ty .
Dri ving and the en vironm ent 197
.,. Never put too much motor oi l in your engine
¢ page 218, Adding engine oil 't:::r..
.,. Never try to push- or tow -start your vehicle.
T he catalytic converter is an efficient "clean ­
up" device bui lt into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
The exclusive use of unleaded fuel is critically important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
The temperature of the exhaust system is h igh, both when driv ing and after stopping
the eng ine.
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not apply additional undercoating or
rustp roofing o n or nea r the exhaust
manifold, exhaust pipes, catalyti c con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
([) Note
-Be aware that just one tank filling with
leaded fuel w ill already ser iously de ­
grade the performance of the catalytic
converter .
- Do not exceed the cor rect engine oil level

- 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

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
