-A tight tether or other strap on a rear ward-fac ing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is actually on the seat. The heavier

Repair, care and disposal of the airbags
Pa rts of the airbag system are i nstalled at
many diffe rent p laces o n your Aud i. Insta llin g,
removi ng, servicing or repa iring a part in an
area of the veh icle can damage a part of an
airbag system and prevent that system from
working properly in a coll is ion.
T he re a re some important t hings yo u have to
know to make sure that the effectiveness o f
t h e system wi ll not be impaired and that dis
carded components do not cause injury or pol
l ute the environment.
A WARNING
Improper care, serv ic ing and repair proce
du res can increase the risk of personal in
j u ry and death by prevent ing an a irbag
from deploying when needed or dep loying
an a irbag une xpec tedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or ai rbag cover
or the in st rument panel or mod ify them
in any way .
- Never attach any objects s uch as c up
holders or telephone mountings to the
sur faces covering the a irbag un its.
- For cle aning the horn pad or instr ument
panel, use only a soft, dry clo th or one
moistened with pla in water. Solvents o r
cleaners could damage the airbag cover
or change the st iffness or strength of the
material so that the airbag cannot de
p loy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru
ment panel, front seats or e lectr ica l sys
tem (including the installation of audio
equ ipment, cellu lar telep hones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment ne cessary.
- For any wo rk on the airbag system, we
strongly recommend that you see your
author ized Audi dealer or qualified work-
shop. ..,.

Knee airbags
Description of knee airbags
T he knee airbag system can provide supple
mental protection to properly restrained
front seat occupants .
Fig. 121 Driv er 's airbag
The drive r knee airbag is in the instrument
panel underneath the steering whee l
~ fig. 121, the airbag for the passenger is at
about the same height in the instrument pan
el underneath the glove compartment .
T he knee air bag offe rs addi tional p rotec tion
to the driver 's and passenger's knees lower
t h igh areas as a supplement to the protection
by the safety belts .
If the fron t airbags dep loy, the knee a irbags
also dep loy in frontal collisions w hen the de
ployment threshold stored in the control unit
is met ~
page 120, More important things to
know about front airbags .
In addition to their normal sa fety function,
safety belts help keeping the driver or front
passenger in position in a fronta l co llision so
that the airbags can provide supp lemental
protection .
T he airbag system is not a substitute for your
safety belt . Rather, it is part o f the overa ll oc
cupant restra int system in your vehicle. A l
ways remember tha t the a irbag system can
o nly he lp to protect you if you are wearing
you r safety belt and wea ring it properly . This
is why you should a lways wear your safety
belt, not jus t be cause the law requ ires you to
do so~
page 103 , General notes.
The safety belt buckle fo r th e driver and front
seat passenger have switch es that tell the air
bag control module if the safety bel t is being
u sed or not .
If the sa fe ty belt is be ing used ,
t h e knee a irbag w ill deploy at a s light ly h igher
rate of dece leration than if the be lt is not be
ing used . Therefore, in a particular co llision, it
is possib le that an airbag will not dep loy at a
seating pos ition where the safety belt is being
used but will inflate at the posit ion where the
safety belt is not being used .
Remember too, airbags w ill deploy on ly once
and only in certa in kinds of acc idents - your
safety belts are always there to offer protec
t io n in those accidents in which airbags are
not supposed to deploy o r whe n they have al
ready dep loyed, for example when your vehi
cl e s trikes or is st ru ck by ano ther after the
first collision . ..,.
128 Airbag system
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints. Al
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passenger
must know and do to help the safety belts and
airbags to provide supplemental protection.
.&_ 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 min imum 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 dep loys or
by being pushed into you as the airbag
deploys .
- Never let anybody, especially children
or animals in the footwell in front of
the passenger seat.
If the airbag de- ploys, this can result in serious or fatal
injuries.
- No objects of any kind should be car
ried in the footwell area in front of the
driver's or passenger's seat. Bulky ob
jects (shopping bags, for example) can
hamper 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

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig. 123 S ide a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
q fig. 123 facing the
doors. They are identified by the word "AIR
BAG".
Th e side airbag system basically consists of:
-the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
the front backrests
- the airbag warning light in the instrument
cluster .
A WARNING
-=
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
-Always follow the manufacturer's in
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position.
- Always make sure that the
PASSENGER
AIR BAG OFF light comes on and stays
on all the time whenever the ignition is
switched on.
(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 an "Advanced
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
Child Safety 133
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, a child should al
ways ride in the seat properly restrained for
its age and size . The airbag on the passenger
side makes the front seat a potentially dan
gerous place for a child to ride. The front seat
is not the safest place for a child in a forward
facing child safety seat .
It can be a very dan
gerous place for an infant or a larger child in a
rearward-facing seat.
Advanced Airbags and the weight
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us
ing the weight-sensing mat in the seat cush
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight-sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger
seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the
seat. The weight of a child restraint and its
"footprint" vary for different kinds of child re
straints and for the different models of the
same kind of child restraint offered by child restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air
bag System. When a child restraint is being
used on the front passenger seat with a

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da
ta Recorde r (EDR), ins talled by some manu
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re
corders".
Some state laws restr ict the retr ieval or down
loading of data stored by EDR's that were in
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron
ic control modules for various v ehicle systems
such as, for examp le, eng ine f unction, em is
sion control, as well as for the airbags and
sa fety belt s.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op
erat ion for diagnostic and repa ir purposes.
T he recording capacity of the electronic con
trol modules is limited to data (no sound is re
corded) and only a small amount of data is ac
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of ve hicle control. It works
only when the eng ine is running . ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course . T he in
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface . When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in
stead of the road surface), ESC will not be
able to help you steer the vehicle because con
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to road , traffic and weather conditions. ESC can
not override the vehicle's physical limits, in
crease the available tract ion, or keep a ve hicle
on the road if road departure is a result of
driver inattent ion . Instead, ESC imp roves the
poss ib ility of keep ing the veh icle under con
t rol and on the road during extreme maneu
vers by using the d river 's steering inputs to
help keep the vehicle go ing in t he i nte nded di
rection . If you are t raveling at a speed tha t
ca uses you to run off the road before ESC can
provide any assistance, you may not experi
ence the benefits of ESC.
ESC includes and/o r works togethe r with the
anti- lock b rake system (ABS), brake assist sys-
tem and anti-slip reg ulation (ASR). ESC is .,..
Power steering
When the engine is running, power steering
makes it easier for the driver to steer.
Power steering he lps the driver steer the vehi
cle with little physical effort .
If the engine is not runn ing, the power steer
ing system is also not wo rking. In this case,
you will find it extreme ly difficult to turn the
steering whee l.
If you t urn t he steering fully to the le ft or
right when the vehicle is stationary, you place
a very heavy load on t he power steering sys
tem . T urning the steering wheel fu lly to the
left or r ight will cause noise in the system . It
a lso reduces engine idle speed.
(D Note
Do not hold the steering turned fully to
the left or right for more than 10 seconds
when t he engine is running. There is a risk
of damage to the power steeri ng system .
@ Tips
-In the event of a power steering system
failure, or if the eng ine is not running
(while being towed), you wi ll st ill be able
to stee r the ve hicle . However, you will re
quire more effort to do so .
- If the power steer ing system has a leak
or is defective, you should immed iately
contact a qualif ied wo rkshop.
- The powe r stee ring system requires a
spec ial hyd raulic f luid. The powe r stee r
i ng fl uid reservo ir is lo cated in the en
g ine compar tment . Th e cor re ct hydra ulic
f lui d leve l is important for p ro per opera
tion o f the power steering sys tem . The
power steer ing fl uid leve l is checked ac
cord ing to the Aud i maintenance service
schedule.
Dry sump Lubrication
H igh lateral and long itud inal forces affect the
engine and the vehicle d uring sporty driving.
Ory sump lubr ication ensures that your eng ine
Int ellig ent technolog y 149
is supplied wi th oi l and properly lubricated
even under these conditions .
In a "no rma l" veh icle the o il pump sends the
o il from the o il p an t o the lubr ication points in
t h e engine. The oi l then ret urns to the o il pan .
In extreme situations , the oil p ump may draw
in a ir, which results in insufficient oi l pressure.
Wi th dr y sump lubri cat ion, the o il is not in the
oi l pan (it is "dry"), but in a separate oil tank.
While one p ump supplies t he e ngine with oil ,
a second pump suctions the oil out of the en
gine and returns it to the oil tank. Because the
o il tank is tall and narrow, oil pressure is con
stant even under extreme conditions .
In add ition, the oi l pan in vehicles with dry
sump l ubrication is noticeab ly shallower. This
allows the engine to be installed lower in the
vehicle , bring ing down the center of grav ity .
