• Always make sure that the side airbag can inflate without
interference:
-Never install se at covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• The airbag sy stem can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy st e m can be deployed only onc e. After an airbag
has been deployed, it must be replaced w ith new replacement
parts de signed and approved es pecially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD.
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circu it interrupter must only be
performed by a qualified dealer -risk of an a ccident!
- If the vehicle or the circu it interrupter is scrapped, all appli­

Other things that can affect Advanced
Airbag performance
Chang ing the ve hicle's suspension system can change the way that
t he Adv anced Airbag System pe rforms in a crash . For example, using
tire-r im combinations not approved by Aud i, lower ing the veh icle,
c hang ing the st iffness o f the suspe nsio n, incl uding the s prings,
s u spension str uts, shoc k absorbe rs etc. can change the forces that
are meas ured by the airb ag sensors and sen t to the ele ctron ic con trol
uni t. Some suspension changes ca n, for examp le, increase the force
levels measu red by t he sensors and ma ke the airbag system dep loy in
crashes in which it wou ld not deploy if the changes had not bee n
made . Other kin ds of changes may re duce the force levels meas ured
by the senso rs and p revent the airbag from dep loyi ng when it should .
The sensors in the safety belt buckle for the d river and front

are wearing your safety belt and wear ing it properly . This is why you
should always wear your safety belt, not just because the law requires
you to do so::::>
page 190, "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is being
used or not. If the safety belt is being used, the knee airbag will
dep loy at a slightly higher rate of deceleration than if the belt is not
being used. Therefore, in a particular collision, it is poss ible that an
airbag will not deploy at a seating position where the safety belt is
being used but will inflate at the position whe re the safety be lt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in kinds
of accidents -your safety belts are always there to offer protection in
t hose accidents in which airbags are not supposed to deploy or when
they have already deployed, for example when your vehicle strikes or
is struck by another after the first collision.
This is just one of the reasons why an airbag is not a substitute for the
safety belt. The airbag system wo rks most effective ly when used with
the safety belts. Therefore, always wear your safety belts correctly .
It is important to remember that while the supplemental airbag
system is desig ned to reduce the likelihood of serious injuries, other
injuries, for example, swe lling, bruis ing, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• Th e electronic control module
• T wo inflatable airbags (airbag and gas generator), one for the
driver and one for the front passenger
• The airbag indicator light in the instrument panel
The knee airbag system will not deploy:
• when the ignition is turned off
• in front-end collis ions when the decelerat ion measured by the
control unit is too low
• in s ide collisions
Safety first Vehicle OP-eration
Airbag system
• in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
minated)
=> page 14 .
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position =>
page 209.
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 203 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=>
page 219, fig. 203. They are identified by the word "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
• 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 turn on the igni­
tion, the airbag system indicator light will come on for a few seconds
(self diagnostics) .
The side airbag system supplements the safety belts and can help to reduce the risk of injury to the driver's and front 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 acceler­
ation registered by the control unit is high enough . If this rate is
below the reference value programmed into the control unit, the side
airbags will not be triggered, even though the car may be badly
Safety first Vehicle OP-eration
Airbag system
damaged as a result of the collision. It is not possible to define an
airbag triggering range that will cover every possible angle of impact,
since the circumstances 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 220, "Important safety instructions on the side
airbag system" .
Aside from their normal safety function, safety 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 occupant restraint system in your vehicle. Always
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 requires you to do so=>
page 190, "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, and minor abrasions can
also be associated with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain kinds of accidents -
your safety belts are always there to offer protection .
Vehicle damage, repair costs or even the lack of vehicle damage are
not necessarily an indication of over-sensitive or failed airbag activa­
tion. In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in which airbags are not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy:
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low
• in front-end collisions

& WARNING (continued)
-Never let a child or anyone else rest their head against the
side trim panel in the area where the supplemental side airbag
inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front seat put their hand or
any other parts of their body out of the window.
• Always make sure that the side airbag can inflate without
interference .
- Never install seat covers or replacement upholstery over the front seat backs that have not been specifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags deploy.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• Objects between you and the airbag can increase the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates. -Never place or attach accessories or other objects (such as
cupholders, telephone brackets, or even large, bulky objects)
on the doors, over or near the area marked "AIRBAG" on the
seat backrests.
- Such objects and accessories can become dangerous projec­
tiles and cause injury when the supplemental side airbag deploys.
- Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers to travel in this position.
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
Controls and equip­ ment Safety first Vehicle operation
& WARNING (cont
inued)
• The airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership.
• Damage (cracks, deep scratches etc.) to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly, their risk of injury increases
in the case of an accident=>
page 222, "Child Safety".
• Never attempt to modify any components of the airbag system
in any way.
• In a side collision, side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger, unclosed openings in
the door panel.
-Never drive with interior door trim panels removed.
- Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- Never drive when loudspeakers in the doors have been
removed unless the speaker holes have been properly closed.
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
inside door panels.
- Always have work on the doors done by an authorized Audi

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of everybody
in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly::::>
page 227.
- Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
retractor on the safety belt to prevent the child safety seat
from moving ::::>
page 232.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety seat
to the front passenger seat, make sure that it is not so
tight that it causes the weight-sensing mat to measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size . ..,
