On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MI L) ¢,ij in the
inst rument cluster is part of the On-Boa rd Diag­
nostic (OBD II) system .
T he wa rning/indicator light ill uminates when the
ignition is sw itched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the li ght do es not go out after the eng ine is
sta rted, or i lluminates while you are driving, a
malfunction may exist in the engine system. If
the lig ht illuminates, the catalytic converter
could be damaged.
Cont inue driving
with reduced power (avoiding
s ustained high speeds and/o r rapid accelera­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i llum inates, the elect ronic speed lim­
iter may also be malf unct ion ing. For more infor­
mation

0 co .... N ,..... N .... 0 0 :c ' depends on the driving mode selected, steering
movements, the driver's braking and accelera­
tion, and as the road surface, vehicle speed and load. A sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle ground clearance depends on the
mode selected and the speed. When you are in
the auto or dynamic mode, the highway setting is
activated when you drive above 75 mph (120 km/
h) for more than 30 seconds. The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times . This sets the steer­
ing to be less sensitive at higher speeds in order
to provide improved vehicle control. At reduced
speeds, steering is more direct in order to keep
the steering effort as minimal as possible when
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 130, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high level of agility and ability to accel ­
erate on curves. The vehicle is very responsive to
steering .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode .
Assist
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Note
- Make sure there is enough clearance above
and below the vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature fluctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspension struts or towing eyes is
not permitted because the pressure in the
air suspension struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatically
engages if the dynamic mode is selected.
- In vehicles that have dynamic steering*, op­
erating noise is heard when starting or stop­
ping the engine. This does not indicate a
problem.

Intelligent Technology
Intelligent Technology
Electronic Stabilization
Control (ESC)
Description
The ESC increases driving safety . It reduces the
risk of s lipping and improves driving stabi lity.
ESC detects critical situations such as when the
veh icle is oversteer ing and understeering or the
wheels are spinning. The vehicle is stabilized by
apply ing the brakes or reducing eng ine torque .
When ESC engages, the
Ji] ind icator light blinks
in the inst rument cluste r.
The fo llow ing systems are integrated in the ESC:
Anti -lock b raking system (ABS)
ABS prevents the whee ls from locking when brak­
i n g . The vehicle can sti ll be steered even d uring
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle.
Brake a ssi st sy stem
The brake assist system can dec rease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat io n is over . In veh icles
w ith adapt ive c ruise control*, the bra ke assis t
system is more sensitive if the distance detected
to the veh icle dr iv ing ahead is too small. On
ve hicles w ith act ivated and functi oni ng night vi­
sion assist*, the brake assist system can respond
more sensit ively if there is a warning .
Anti-slip regulation (ASR)
A SR red uces eng ine power when the d rive wheels
begin s pinning and ad apts the force to the road
conditions. This makes it easier to sta rt, acceler ­
ate and dr ive up hi lls.
Electronic differential lock (EDL )
EDL applies the brakes to a wheel that sta rts
sp inning and t ransfe rs t he d rive powe r to t he
o ther d riving w heels. This f unct ion is not av aila ­
b le at higher speeds .
126
In extreme cases, ED L automat ically switches off
to keep the b rake on the braked whee l from over­
heating. The veh icle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendat ion
The E SC he lps to stabili ze the vehicle by changing
the steering torque.
I n veh icles with dyna mic steer ing*, ESC a lso
helps to sta bilize the s teer ing in cr it ica l situa ­
tions.
Selective wheel torque control
Se lective wheel to rque cont rol is used when d riv­
i ng on curves.
The fro nt wheel on the ins ide of the curve or bo th
whee ls on the inside of the curve are braked se­
l ectively as needed. This allows more pre cise d riv­
i ng in cu rves. The applicab le system may no t ac ti­
vate when dr iv ing in we t or snowy condi tio ns.
Automatic post -collision braking system
The "automat ic post-coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c ontro l modu le detects a collision above a cer tain
vehicle speed, the ve hicle is braked by the ESC.
The veh icle does not b rake automatically if:
- the drive r presses the acce lerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle electri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially impor tan t
on s lippery or wet roads. If the system s be­
g in a cting to stabilize yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let t he i ncreased safety provi ded tempt

Intelligent Technology
The stee ring wheel will be easy to move after
starting the engine . Re-initialization might be
necessary if the steering whee l was moved hard
t o the lef t and right wh ile the vehicle was not
mov ing. The display turns off if the initialization
was successful.
(D Tips
- If the. or
1;:r- ij ind icator light only stays on
for a short time, you may continue driving.
- The dynamic steering stability systems
c> page 126 are not available in the event of
a system ma lfunction.
- For additional informat ion on dynamic
steering, refer to
c> page 110.
All wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In a ll wheel drive, the driving power is divided be­
tween a ll four wheels . T his happens automatical ­
ly depending on your driving behavior as well as
t he current road cond itions. Also see
c> page 126, Electronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear whee ls is variable and can be
ad ju sted using the dr ive select
c> page 110.
The all wheel drive concept is designed for h igh
eng ine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iv ing condit ions and on
snow a nd ice. Always read and fo llow safety pre­
cautions
c> .&. .
Winter tires
By us ing all w heel d rive , yo ur vehicle has good
forward mot ion w ith standa rd t ires in winter con­
d itions . However, in winter we recommend us ing
w in ter o r all season t ires o n all fo ur wheels, be ­
cause this will improve the b raking effect .
Snow chains
If there are snow chai n laws, snow chains must
a lso be used on vehicles with all w heel d rive
c> page 298, Snow chains .
130 Replacing tires
Fo
r vehicles wi th a ll wheel d rive, o nly wheels with
the same ro ll ing circ umfe rence sho uld be used .
Avo id using tires with different tread depths
c> page 290, New tires or wheels .
Offroad vehicle?
You r A udi is not an off road vehicle -there is not
enough ground clearance. For th is reason, avoid
difficult terrain .
A WARNING
- Also, in ve hicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel d rive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is s lippery, be ­
c a use th is i ncreases the r is k of an accident.
- Note that on wet st reets, the front wheels
c a n " hydroplane " if driv ing at speed s tha t
are too high. Unlike front wheel drive
vehicles, t he engine does not rev higher sud ­
de nly when the vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is no t drive n for a long t ime, the veh icle bat­
te ry is drained by equ ipment (fo r example, the
i mmob ilizer). In certa in circ umstances, there
could may not be enough energy to start the en ­
gine.
