Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly.
~ Read all the information that follows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death .
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents . For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving.
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. In some
vehicles, there are four seat ing positions : two
in the front and two in the rear. Each seating
position has a safety belt .
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death .
- Never strap more than one person, in­
cluding small chi ldren, into any belt. It is
especially dangerous to place a safety
belt over a child sitting on your lap.
Safety belts 145
-Never let more people ride in the vehicle
than there are safety belts available.
- Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
~-Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger to remind you
about the importance of buckling-up.
Fig. 155 Safety bel t warning light in the instrument
cl uster -enla rged
Before driving off, always:
~ Fasten your safety belt and make sure you
are wearing it properly .
~ Make sure that your passengers also buck le
up and properly wear their safety belts.
~ Protect children with a child restraint sys-
tem appropriate for the size and age.
The warning light . in the instrument cluster
lights up when the ignition is on as a reminder
to fasten the safety belts. In addition, you will
hear a warning tone for a certain period of
time .
Fasten your safety belt and make sure that
your passengers also properly put on their
safety belts.
A WARNING
- Safety belts are the single most effect ive
means available to reduce the risk of se­
rious inju ry and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving. •

160 Airbag sys te m
- Always make su re the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front a nd side airbag .
- Never put the forward- facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lli ng
the fo rward-facing chi ld restraint. The
b ackres t must be adjusted to an upr igh t
posit ion.
- Make su re that the

on.
Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide information to the Advanced Air­ bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator and
cont ro l valve for the driver ins ide the steer ­
ing wheel hub .
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the inst rument panel for
the front passenger .
- A we ight-sensing mat under the up ho lstery
padding of the front passenge r seat cushion
that measures the total weight o n the seat.
The info rma tion reg iste red is sent continu­
ously to the elec troni c control un it to regu­
la te deployment o f the front Advanced Air ­
bag on the passenger side .
- An airbag monitor ing sys tem and indicator
light in t he instr ument cluster ¢

-A sensor in each front se at regis ters the dis ­
t ance between the respec tive seat and the
steering whee l o r instrument panel. The in­
formation registered is sent continuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adv a need A irbags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel ¢

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tect ion in a frontal crash.
- If the airbag indicator light
c:> page 18
comes when the vehicle is be ing used,
have t he system inspected immediate ly
by you r authorized Aud i dea le r.
It is pos­
s ible that the a irbag will inflate when it
is not s upposed to, or w ill not inflate
w hen it sho uld.
A WARNING
If the front air bag infla tes, a c hild wi tho ut
a chil d restra int, or in a rearward-fac ing
child safety seat, or in a forward-facing
child rest raint that has not been prope rly
installed will be serious ly injured and can
be killed.
- Even though your ve hicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride on the
back seat properly restra ined fo r the ir
age and size .
- Always insta ll forward or rea r-facing
child seats on the rea r seat -even w ith
an Advanced Airbag System.
- If you must install a rearward-fac ing
child seat on the front passenge r seat
because of except io na l circumstances
and the
PASSENGER AIR BAG OFF ligh t
does not appe ar and stay on, imme diate- ly insta
ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
- A t ight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too
much p ressu re on the weight-sensing
mat in the seat and reg iste r mor e we ight
than is actually on the seat. The heavie r
weight regis tered can make the sys tem
wo rk as though an adult we re on the seat
and deploy the Advanced Airbag when it
m ust be suppressed causing serious or
even fata l injury to t he chi ld .
- If, in exceptiona l circumstances, you
m ust install a forward-facing c hild re­
straint on the front passenger seat, al ­
ways move the seat into its rearmost po­ sition in the seat's fore and aft ad just­
ment range, as far away from the a irbag
as poss ible. The backrest mus t be ad just­
ed to an upright pos ition. Make su re that
the
PASSENGER AIR BAG OFF light
comes on and st ays o n all the time when ­
eve r the ignit ion is swit ched on .
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go o ut when an a dult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adu lt is properly seated and restra ined at
one of the rear seat ing pos itions.
- Have the airbag system inspected by
your Aud i dealer before transporting
a nyo ne on the front passenger seat .
(D Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned off, and the
PASSENGER AIR BAG
OFF
light will stay on.
Repair , care and disposal of the airbags
Pa rts of the airbag system are installed at
many different places on your Aud i. Insta lling, ..,.

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 177, Child Safety.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
---
Fig. 171 Side airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢fig. 171 and the rear
backrest facing the doors. They are identified
bytheword "AIRBAG".
The 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
- two rear side airbags
Airbag system 1 71
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics).
The side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear passenger's
upper torso on the side of the vehicle that is
struck in a side collision. The airbag deploys
only in side impacts and only when the vehicle
acceleration registered by the control unit is
high enough.
If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­
sult of the collision.
It is not possible to de­
fine an airbag triggering range that will cover every possible angle of impact, since the cir­
cumstances will vary considerably between
one collision and another. Important factors include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc. ¢
page 173, Important
safety instructions on the side airbag system.
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wearing it properly. This
is another reason why you should always wear
your safety belts, not just because the law re­
quires you to do so¢
page 145, General
notes.
It is important to remember that while the
supplemental side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising,

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict 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.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The 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 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 vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 199
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
JjJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
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 interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways 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 traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
