Fully inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the risk of injury.
Important safety instructions on the
knee airbag system
App lies to vehicles: with knee airbags
Airbags are only supplemen tal restraints. Al
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt. The risk in
creases even more should the airbag de ploy.
- Always make sure that the knee airbag can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or
Airbag system 165
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
of the passenger seat.
If the airbag de
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or
passenger's seat. Bulky objects (shop
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air bag deploys and injure you or your pas
sengers .
- Make sure there are no cracks, deep scratches or other damage in the area of
the instrument panel where the knee air
bags are located.
- If children are incorrectly seated, their
risk of injury increases in a collision

¢ page 169, Important things to
know.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re
quirements for 3-and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup
pression" requirements of the Safety Stand
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list
ed in the Standard .
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe
cially those 12 years and younger, should al
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas
senger side makes the front seat a potentially
dangerous place for a child to ride. The front
seat is not the safest place fo r a child in a for
ward-facing child safety seat. It can be a very
Child Safety 1 71
dangerous place for an infant or a larger child
in a rearward-facing seat.
The vehicle's Advanced Airbag System has a
capacitive passenger detection system in the
front passenger seat cushion that can detect
the presence of a baby or a child in a child re
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri
cal field when a child, a child restraint, and a
baby blanket are on the front passenger seat .
The change in the measured capacitance due
to the presence of a child, a child restraint,
and a baby blanket on the front passenger
seat is related to the child restraint system resting on the seat . The measured capacitance
of a child restraint system varies depending
on the type of system and specific make and model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System control unit together with the capacitances typical of infants and a 1-year
old child. When a child restraint is used on the
front passenger seat with a typical 1 year-old infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control unit.
Child restraints and Advanced front
airbag system
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in excep
tional circumstances you must use it on the
front passenger seat, ca refully read all of the
information on child safety and Advanced Air-
bags and heed all of the applicable ..,.

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-
mal. .,._

Stee ring re comm endat ion
The ESC helps to stabilize the vehicle by
changing the steering torque.
Selective wheel torqu e control
Select ive wheel torque control is used when
driving on curves . The front wheel on the in
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more precise driving in curves.
Automatic post -collisi on brakin g system
The "Automatic post-collision braking system "
can help to reduce the risk of slidi ng and of
other coll is ions afte r an accident. I f the airbag
con tro l modu le detects a collision above ace r
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning.
A WARNING
-The ESC and its integrated systems can
not overcome the limits posed by natura l
physical laws. This is especially impor
tant on s lippery or wet roads. If the sys-
Switching on/off
Sm art Te chnol og y 189
terns beg in acting to stabilize your vehi
cle, you should immediately alter your
speed to match the road and traffic con
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli
SIOn.
- Please note the r isk of a coll is ion increas
es when driving fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and its integrated systems can
not a lways prevent collisions -there is
still a risk of accidents!
- Press the accelerator pedal caref ully
when acce lerating on even, slippery sur
faces such as ice and snow. The drive
wheels can spin even when these control systems are installed and this can affect
driving stability and increase the r isk of a
coll is ion.
@ Tips
-ABS and ASR only function correctly
when all four wheels are equipped w ith
identical tires. Different t ire sizes can
lead to a reduct ion in engine power.
- You may hear noises when the systems
descr ibed are working.
- If the
Bl or [I] indicator light appears,
there may be a malfunction
¢ page 21.
ESC turns on automatically when you start the engine .
Fig. 159 Upper c ente r conso le: ESC button
The ESC is designed to funct ion in levels . De
pend ing on the level that is selected, the sta
bilization funct ion of the ESC is lim ited or
swi tched off . The amoun t of stabilization con
trol wi ll differ depending on the level.
In the follow ing unusual situations it may
make sense to switch the ESC sport mode on

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
• Do not drive vehicle: steering defective
If this indicator light turns on and stays on
and this message appears, the power steering may have failed.
Do
not continue driving. See an authorized
Audi dea ler or authorized Audi Service Facility
for assistance.
• Do not drive vehicle: steering defective
There is a malfunct ion in the electron ic steer
ing lock. You cannot turn the ign ition on.
Do
not tow your vehicle because it cannot be
steered. See an authorized Aud i dealer or au
thor ized Audi Serv ice Facility for ass istance.
'I j Steering malfunction: you can continue
driving
If the indicator light turns on, the steering
wheel may be more difficult to move or more sensitive than usual.
The stee ring wheel may
also be at an angle when driving straight.
Drive slowly to your authorized Audi dealer or
qualified wo rkshop to have the malf u nct ion
corrected.
II Steering lock : system fault! Please con
tact Service

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
Q ,& . .,.
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. ~
page 19 .
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.

230 Tires and wheels
-If you notice unusual vibra
tion or if the vehicle pulls to
one side when driving, al
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam
age.
0 Note
-Please note that summer and winter tires are de
signed for the conditions
that are typical in those sea
sons. Audi recommends us
ing winter tires during the
winter months. Low tem peratures significantly de
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi
tions. The surface of the
rims does not have suffi
cient corrosion protection
for this and could be perma
nently damaged by road salt
or similar substances.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indi
cate a low sidewall for im
proved steering response and
better overall handling on dry
pavement.
...

" > co ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
Driving style
Driving fast around curves,
heavy acceleration and hard
braking increase tire wear.
Rotating tires for more even
wear
For all four tires on your vehicle
to have the same service life,
we recommend that the front
and rear tires are rotated ac
cording to the tire manufactur
er's suggested tire rotation in
tervals. Please remember the
following:
-Tire rotation intervals may dif fer from the vehicle service intervals outlined in your Warranty
& Maintenance booklet .
-The longer one tire is used in one location on the vehicle ,
the more it wears at certain points; therefore, we recom
mend that you follow the tire
manufacturer's suggested tire
rotation intervals.
-Vehicles with front-wheel drive experience more tread
wear on the front wheels com
pared to all-wheel drive (quat
tro).
-Please rotate ti res as shown
¢ fig. 175.
Tires and wheels 24 7
-Extra care must be taken when rotating direction-specific
tires ¢
page 268.
Wheel balancing
The wheels on new vehicles are
balanced. However, various sit
uations during everyday driving
can cause them to become un balanced, resulting in vibra
tions you can usually feel
through the steering wheel.
Unbalanced wheels must be re
balanced to avoid excessive
wear on steering, suspension
and tires. A wheel must also be rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, impairing the safety of the vehi
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must al
ways have tires of the same size, construction and tread
type . For details see
¢ page 192 .
