is below the reference value programmed into the cont rol unit, the
side airba gs w ill no t be triggered, even though t he car may be b ad ly
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 229, "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 201, "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 229.
• 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.

Aside from their norma l safety function, safety be lts work to he lp
kee p th e dr iver or fron t p asse n ger in posi tion in t he even t of a c olli­
sion so that the side cu rtain a irbags can provide protection.
T he a irbag system is not a substitute for your safety belt . Rathe r, it is
par t of the ove rall o ccu pan t res traint syste m in your vehicle . A lw ay s
remember t hat the airba g system can on ly help to protect you if you
a re we ari ng your safety bel t and wearing it prop erly. Thi s is ano ther
reaso n why you s hou ld always wea r your safety be lts, not just because
th e law requi re s you to do so=>
page 20 1, "G ene ral no tes".
It is i mpo rtant to re m ember that while the s ide curta in airbag system
is des igned to help re duce the likelih ood of serious injuries, ot her
i n jur ies, fo r exa mple, sw elling, br uising, a nd m inor ab rasions can
also be assoc iated wit h these airbags upo n dep loyment . Remembe r
t o o , these a irbags w ill d eploy only on ce an d on ly in ce rt ain kinds of
acc idents -yo ur safety belts are always there to offer protection.
The side curtain airbag system basically consists of:
• Th e electronic co ntro l mo dule an d external side impact sensors
• The side c urtai n airbags above the fro nt an d rear s ide windows
• Th e airba g indic ator ligh t in the ins trumen t panel
Th e a irbag system is monitored elec tron ically to make certai n it i s
functioning prope rly at a ll times . Each time yo u turn on the ignition,
t h e airbag sys tem indicator ligh t w ill com e on for a few seconds (s elf
diagnostics) .
The side curtain airbag is not activated:
• if the ignition is tu rned off
• in side co llisions when the accelerati on measured by the sens or is
t o o low
• in rear-end collisions.
Safety first Vehicle OP-eration

& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position =>
page 85,
"General recommendations ".
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to activate the airbag.~

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 ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These
child restraints are:
A. Car beds, manufactured on or after September 1,
2004:
• Cosco Dream Ride 02-719
B. Rear facing child restraint systems,
manufactured on or after September 1, 2004:
(When the restraint system comes equipped with a removable base,
compliance has to be cert ified with or without the base) .

• Century Assura 4553
• Century Smart Fit 4543

Us ing the ABS sensors, the tire pressure monitoring system compares
t he t ire tread c ircumference and vibrat ion characte rist ics o f the indi ­
vidual tires. If the pressure decreases in one or more tires, this is indi­
cated in the ins trument cl uste r wi th a warning symbol
1 and a
message=> fig. 246 . The dr iver message in the display goes o ut after
5 seconds . T he driver message can be disp layed again by p ressing the
[ CHECK ] button. If only one t ire is affected , the display will ind icate
its position . The tire press
ure monitoring must be reset via MMI each time the
pressu res are adju sted (e.g. when sw itching between partial and full
load pressure) or after chang ing or replacing a t ire on your veh icle
=>
page 339. You can find the recommended tire pressures fo r your
vehicle on the label o n the dr iver's door pillar=>

soon as poss ible.
& WARNING
• If the tire pressure indicator appear s in the instrument cluster
display, one or more of your tires is significantly under-inflated.
Reduce your speed imm ediately and avoid any hard steering or
brak ing maneuvers . Stop as soon as possible and check the tires
and their pres sures. Inflate the tire pre ssure to the proper pres­
s u re as indicated on the vehicle 's tire pressure label=>
page 322.
Driving on a significantly under-inflated tire cau ses the tire to
overheat and can lead to tire failure . Under-inflat ion also is l ikely
to impair the vehicle 's handling and stopping ability .
