& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates - even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof .
• Always install rear-facing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
& WARNING (continued)
• 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.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• 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 forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury, make sure that the PASSENGER AIR BAG OFF light will be displayed whenever a child
restraint is installed on the front passenger seat and the ignition
is switched on .
• If the PASSENGER AIR BAG OFF light does not stay on, perform
the checks described
~ page 220 , "Monitoring the Advanced
Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately.
• Always carefully follow instructions from child restraint manu
facturers when installing child restraints.

& WARNING (co ntinued )
• Always install forward or rear-facing child safety seats on the
rear seat - even with an Advanced Airbag System .
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circum stances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear-facing child safety seat in a rear
seating pos ition and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether or other strap on a rearward-facing child
restraint attached to the front passenger seat can put too much
pressure on the weight-sensing mat in the seat and register more
weight than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it must be suppres sed
caus ing serious or e ven fatal injury to the child.
• If, in exceptional circumstances, you must install a forward
facing child restraint on the front passenger seat, always move

• Never cover, obstru ct, or change the steering wheel horn pad or
a irbag cover or the instrument panel or modify them in any way .
• Never atta ch any objects such as cupholders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel, use only a soft,
dry cloth or one moistened with plain wate r. Solvents or cleaners
c ould damage the airbag cover or change the stiffne ss or strength
of the mater ial so that the airbag cannot deploy and protect prop

damaged as a result of the collision. It is not possible to define an
airbag tr iggering range that w ill 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 227, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to help
keep the d river or front passenger in posit ion in the event of a side
co llision 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 ove rall occupant restraint system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wearing your safety belt and wearing it p rope rly. This is
another reason why you shou ld always wear your safety belts, not just
because the law requires you to do so~
page 199, "General no tes" .
It is important to remembe r that wh ile the supp lemental s ide airbag
system is designed to reduce the likelihood of se rious injuries, ot her
injuries, fo r examp le, swe lling, bru ising, and minor abras ions can
also be associated with deployed side airbags . Remember too, side
airbags will dep loy only once and only in certai n kinds of accidents -
your safety belts are always there to offer protection.
Vehicle damage, repair costs or even the lack of veh icle damage a re
not necessar ily an ind ication of over-sensitive or failed airbag activa
t ion . In some collisions, both front a nd side airbags may inflate .
Remember too, that a irbags will deploy only once and only in certa in
kinds of collisions -your safety belts are a lways there to offer protec
tion in those acc idents in w hich airbags a re 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 collis ions
• in rea r-end collisions
• in rollovers .
In some types of accidents the front a irbags, side curtain airbags and
side airbags may be triggered together.
& WARNING
• Safet y belts and the airbag s ystem will only provide protection
when o ccupants are in the proper seating position ~
page 227.
• If the airbag indicator light comes on when the vehicle i s being
used, have th e system inspe cted immediately by your authoriz ed
Audi dealer. The airbag may not work prope rly when the vehicle
a cceleration in a side collision is high enough to activate the
ai rbag. •
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are pro perly
restrained.
