Intelligent technology
Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event w ithout the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le-related data
during norma l vehicle opera tion for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, direction,
braking as well as restraint system use and performance in the
even t of a crash or other condition . Stored data can only be read and
downloaded with special equipment.
Electronic Stabilization Program (ESP)
Genel'61
The Electronic Stability Program increases driving
sta bility.
Fig . 13 0 Cente r
cons ole with ESP
sw itch
With ESP, control over the veh icle is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
H ow ESP work s
The ESP control unit processes the following data from high-sensi ­
tive sensors: the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior . If the two do not match, for example when

the vehicle begins to skid, ESP brakes the appropriate wheel auto­matical ly .
The vehicle is stabilized again by the forces acting on the wheel during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed .
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:>
page 187. If there is ma lfunc­
tion in the ABS, ESP is also inoperative .
Activa ting
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode . With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 182, fig. 130 returns the
system to normal operation.
D eac tiva ting
ESP should norma lly be activated at all times because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the Elec ­
tronic Stability Program !ESP) by pressing the button =:>
page 182,
fig. 130. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by slow flashing of the ESP
lamp in the instrument c luster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when rocking the car free), it may be necessary to deactivate ASR. Deacti ­
vation is effective only up to a speed of about 45 mph (70 km/h). At higher speeds, ASR is switched on again automatical ly in front ­
whee l drive vehicles, deactivation is possible only up to about 30
mph (50 km/h). With all -whee l drive vehicles, ASR is active above
Controls and equip­
ment Safety first Vehicle operation
In
te llig ent tec hn olo gy
about 45 mph (70 km/h) and deactivated automatical ly below this
speed.
D eac tiva tin g ES P/ASR
Press the button for more than 3 seconds . Deactivation is indicated
by the ESP lamp in the instrument c luster staying on permanently .
This deactivates the E lectronic Stabi lity Program (ESP) in addition to
ASR . No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traff ic situation permit .
& WARNING
• The limi ts of ph ysics ca nnot be suspe nd ed by E SP. E ven in vehi ­
cles w ith ESP, you should always adapt your dr iving to road and

Electronic differential lock (EOL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or
almost no grip. Without EDL, this would be difficult, if not impos ­
sible.
How the system works
Th e EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=> page 187. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground on
one side), the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/hl. Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=> page 20. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates , the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface .
How the system works
ASR performs automatically, i.e. without the driver's intervention .
With the aid of the ABS sensors => page
187, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface . The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action .

Braking
General "nformation
W hat aff ects braking effi cie ncy?
Operating condition s and driving habits
The brakes on today's automob iles a re sti ll sub ject to wea r,
depending large ly o n operati ng co nditions and driving habits~& .
On vehicles that are either driv en mostly in stop -and -go city traffic
or are driven hard, the brake pads shou ld be c hecked by you r au tho ­
ri ze d Audi dea ler mor e often than sp ecified in the
Warranty & Main ­
tenance booklet.
Fai lure to have your brake pads inspected can
resu lt in reduced brake performance.
On s teep sl opes, you should use the braking effec t of the engine .
T his way, you prevent unnecessary wear on the brake sys tem . If you
must use your brakes, do not hold the brakes down continuous ly.
P ump t he b rakes a t interva ls.
Moi sture or road salt
Under certa in conditions, for example , when driving through water
or
ve ry heavy rai n, o r even afte r washing you r ve hicle, the brak ing
e ff ect can be reduced due to moisture (or in freezing cond it io ns ice)
on the brake pads . A few cautious brake applications should dry off
the brake pads or remove any ice coat ings.
T he effectiveness of the brakes can be reduced when the vehic le is
driven on a sa lt-c o ve re d r oad and the brake s are not used . Likew ise,
you clean off accumulated sa lt coat ing from brake discs and pads
wit h a few cau tious applica tions of t he brake ~& .
Corrosion
There may be a tendency for d irt to buil d up o n the b rake pads a nd
corrosion to form on the discs if the car is not driven regular ly or
only for sho rt trips wi th lit t le use of the brakes. ._
