• With the front seats, the height adjustment of the seat can also
be used to adjust the position of the safety belts. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
nes.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly
positioned on the body . Improper seating positions reduce
the effectiveness of safety belts and will even increase the
ris k of injury and death by moving the safety belt to critical
areas of the body . Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and str ikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­ pants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear -end collisions above a particular
severity and in a rollover, safety belts ore tensioned auto­ matically.
The safety belts are equ ipped with safety belt pretensioners. The
system is activated by sensors in front, side and rear-end collisions of
great sever ity and in a rollove r. This tightens the belt and takes up
belt slack ~
& in "Service and disposal of safety belt pretens ioner"
on
page 210. Ta king up the slack helps to reduce forward occupant
movement during a collision.
0 Note
Never let the belt rema in over a rear seatback that has been folded
forward .
[ i ] Tips
Th e safety belt pretensioner can only be activated once .
• In m inor fronta l and side collisions, in rear-end coll isions and in
acc idents involving very little impact force, the safety belt preten­
sioner are not activated.
• Whe n the safety belt p retensioners are activated, a fine dust is
re leased. This is normal and is not caused by a fire in the vehicle.
• T he relevant safety requirements must be observed when the
vehicle or components of the system are s crapped. An authori zed

Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 204 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 204 and the rear backrest* facing the doors . They are identi ­
fied by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external side impact se nsors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster.
Th e airbag system is monitored elect ronically 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 d iagnostics).
The side airbag system supp lements the safety belts and can he lp to
reduce the risk of injury to the dr iver 's, front and rear* passenger 's
upper torso on the side of the vehicle that is struck in a side collision.
The airbag deploys on ly in s ide impacts and only when the vehicle
acceleration registered by the control unit is high enough. If this rate

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.

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

s u re as indicated on the vehicle 's tire pressure label=>

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 .
