Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is installed by some vehi­
cle manufacturers to record data about crash­
es so that 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 vehicle is not equipped with a crash data recorder. However it does contain a variety of
electronic control modules for various vehicle
systems such as engine function, exhaust
treatment or airbags and safety belts .
These electronic control modules record vehi­ cle data during normal driving for diagnosis
and repair purposes . The recording capability
of the electronic control modules is limited to
data only- no sound is recorded.
If the control
module detects a system ma lfunction or other
change in status, a very limited amount of da ­
ta is recorded for an extremely small period of
time . Data that is recorded in such a case may
include vehicle speed, d riving direction, the
load on the brakes and head restraints and
performance in the event of an acciden t or
other change in status . The stored data can
only be read or downloaded with special devi­
ces.
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) con­
tr ibutes to driver safety. It reduces the risk of
slipp ing and improves driving stability. ESC
Smart Technolog y 189
detects critical situations such as the vehicle
oversteering and understeering or the wheels
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torque.
Once the ESC is activated, the indicator light
m blinks in the instrument cluster .
The following systems are integrated in the
ESC:
Anti-lock braking system (ABS )
ABS prevents the whee ls from locking when
braking. The vehicle can still be steered even
during hard braking. Apply steady pressure to
the brake pedal. Do not pump the pedal. A
pulsing in the brake peda l indicates that the
system is acting to stabilize the vehicle.
Brake assi st sys tem
The brake assist system can decrease braking
distance. 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 dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sensit ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin spinning and adapts the force to
the road conditions . This makes it easier to
start , accelerate and dr ive up inclines .
Electronic differential lock (EDL)
The EDL brakes wheels 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 available
at higher speeds .
In extreme cases, EDL automatically switches
off to keep the brake on the braked wheel
from overheating . The vehicle is still working
correctly. EDL will switch on aga in automat i­
cally when cond itions have returned to nor-
mal. .,..

the brakes. If you need to brake addit ion ­
ally, bra ke in intervals and not continu­
ously.
(D Tips
- If the brake boos ter is not wor king, you
must p ress the brake pedal with much
more force t hen no rma l.
- If yo u retrof it your vehicle with a front
s po ile r, wheel covers or similar items,
make sure that the air f low to the front
whee ls is not interrupted. Otherwise the
brake system can become too hot.
Electromechanical
steering
The elec tromechanical steering suppor ts the
driver's s teering movements .
Powe r stee ring adapts electronically based o n
the veh icle speed.
The vehicle still has full stee ring fu nctionality
if the powe r steering fails o r whe n the eng ine

196 Smart Technology
- How far (if at all) the driver was depress ing
the accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp provide a better under­
stand ing of the circumstances in which crash­
es and injuries occur. NOTE: EDR data are re­
corded by your vehicle only if a non-trivial
crash situation occ urs; no data are recorded by
the EDR under normal driving conditions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, could
comb ine the EDR data with the type of per ­
sonally identify ing data routine ly acquired
du ring a crash invest igation.
To read data recorded by an EDR, special
equipment is required, and access to the veh i­
cle or the EDR is needed . In add ition to the ve­
hicle manufactu rer, othe r parties, such as law
enforcement, that have the special equip­
men t, can read the information if they have
access to the vehicle or the EDR.
Some state laws restrict the retrieval or down­
loading of data stored by EDRs installed in a
vehicle for the express purpose of retrieving
data after an accident or crash event without
the owner's consent.
Aud i will not access the EDR and/or similar
data or give it to others -
- unless the veh icle owner (or lessee if the ve­
hicle has been leased) ag rees; or
- upon th e official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju­
dicial discovery process.
- Audi may also use the data for research
about veh icle operation and safety perform­
ance or provide the data to a third party for
research purposes without identifying the
spec ific vehicle or information about the
identity of its owner or lessee and o nly after
the recorded vehicle data has been ac­
cessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emis­
sion control, airbags, and safety belts.
T hese electronic control mod ules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modu les is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very limited period of
t ime, or stored when a system fault is detect­
ed by a contro l module . Some of the data
stored may relate to vehicle speed, direction,
or braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also on ly be read and down loaded
with special eq uipment that is directly con­
nected to the vehicle .
(D Tips
Your vehicle may be equipped with Audi
connect. Your use of certain A udi connect
features requires wireless services that are
provided by a third party wire less telecom­
munications provider. For details regard­
in g how information obtained through
Audi connect is collected, processed,
transmitted, used, and shared, please see
your contract with the wireless telecom­
munications provider and the" About Audi

can reach the catalytic 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 accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance 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 Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur 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.
Diesel particulate filter
Applies to vehicles: with d iesel eng ine
The diesel particulate filter fi lters nearly a ll of
the soot part icles out of the exhaust. The fil­
ter cleans itse lf automatically under normal
driving conditions. If the filter cannot clea n it­
self (for examp le, because you are only driving
short d istances) , the fil ter becomes clogged
with soot and the

particulate f ilter illum inates ~ page 23.
A WARNING
- Do not park yo ur vehicle ove r flammable
materials such as g rass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could
start.

Placing your vehicle
out of service
If you would like to take your vehicle out of
se rv ice for a longer time, contact your author­
ized Audi dealer or qualified repair fac ility .
They w ill advise yo u of impo rtant measures,
such as corrosion p rotection , maintenance
and storage p roced ures. Also follow the infor­
ma tion about the battery ~ page 228 .
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, env ironme ntal impact, and
wea r on your eng ine, b rakes and tires la rgely
depend on three factors:
- your personal d riving s tyle
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent. This sec­
tion w ill give you some tips on how you can
help t he env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTECTION AGENCY
(EPA) and Transpo rt Canada may not corre­
spond to your actual consumption on the r oad, which will va ry depending upon vehi ­
cle load and speed, ro ad and weather con­
ditions, trip leng th, etc.
Drive smoothly and keep a lookout
ahead

Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary electric radiator fan switches on
and off depending on coolan t temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself<=>.& , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

.. Read the brake fluid level from the brake
fluid reservoir <=>

fig. 159.
T he brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
<=>page 220.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)
I. (Canadian
models) will come on
c:> page 18 . Do not con­
tinue to operate the vehicle. The complete
brake system should be thoroughly checked
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 light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air . If
the water content in the brake fluid 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.
Therefore, the brake fluid must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the brake 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.
