Airbag syste m
-the e lectronic control module and external side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear backrest
- the ai rbag warning light in the inst rument cl us-
ter .
The a irbag system is monitored electron ica lly to
make certa in that it is function ing properly at a ll
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can he lp to reduce the risk of injury to
the driver 's, front and rear passenger 's upper tor­
so on the side of the vehicle that is struck in a
side collision. The airbag deploys only in side im­
pacts and on ly when the vehicle accelera tion reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the contro l unit , the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision.
It is not pos ­
sible to def ine an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
t he impacting object, the angle of impact, vehicle
speed, etc. ¢
page 163, Important safety in ­
structions on the side airbag system.
Aside from the ir norma l safety function, safety
be lt s work to help keep the dr iver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protect ion.
The airbag system is
not a subst itute for your
safety belt. Ra ther, it is part o f the overall occu­
pant restraint system in your vehicle . Always re ­
member that the s ide a irbag system can only
he lp to protect you if you are wear ing your safety
be lt and wearing it p roperly. This is another rea­
son why you shou ld always wea r you r safety
be lts, not just because the law requ ires you to do
so ¢
page 135, General information.
It is important to remember that while the sup­
p lemental side airbag system is des igned to re-
162
duce the like lihood of serious injur ies, other inju­
ries , for example, swelling, bruising, friction
burns and m inor abrasions can a lso be associated
with deployed side airbags. Remember too, s ide
airbags will dep loy only once and only in certain
k inds of accidents -your safety belts are always
the re to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are no t necessarily an indication
of over-sensitive or failed airbag activation . In
some collis ions, both front and side ai rbags may
i nflate . Remember too, that a irbags w ill deploy
o nl y once and on ly in certa in kinds of collisions -
you r safety be lts a re a lways there to offer p rotec­
tion in those accidents in which airbags are not s u pposed to deploy or when they have a lready
deployed.
The side airbag system will not deploy:
- when the ignit io n is swit ched off
- in side co llisions when the accele rat ion meas-
ured by the senso r is too low
- in front-end collisions
-in rear-end collisions
- in rollovers.
In some types of accidents the front airbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position
¢ page 163.
-If the airbag ind icator light¢ page 18
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer .
It is possible that
the airbag will in flate when i t is not sup­
posed to, or will not infla te when it should.

below the refe rence value p rogrammed into the
control unit, the side curtain airbag will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision. It is not pos ­
sible to define an airbag triggering range that
will cover every poss ible angle of impact, since
the circumstances will vary considerably between one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle speed, etc.¢
page 165, How side curtain air­
bags work.
Aside from the ir normal safety function , safety
be lts work to help keep the dr iver or front pas­
senger in posit ion in the event of a co llision so
that the side curtain a irbags can provide protec­
tion.
The airbag system is not a s ubst itute for yo ur
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the airbag system can only help to
protect you if you are wear ing your safety be lt
and wearing it properly. Th is is another reason
why you should always wear your sa fety bel ts,
not just because the law requires you to do so
¢ page 135, General information.
It is important to remember that while the side
curta in airbag system is designed to help reduce
the likelihood of serious injuries, other injur ies,
for example , swelling , b ruising, fr iction burns
and minor abras ions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certain k inds of accidents -your safety belts are
always there to offer protectio n.
The side curtain airbag system basically
consis ts of :
- The elec tronic contro l mod ule and externa l side
impact sensors
- The side c urtain a irbags above the front and
rear side windows with ejection mitigation fea­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monitored elect ron ically to
make certa in it is function ing properly a t all
Ai rb ag sy stem
times . Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
Th e s ide curtain airbag is not activated:
- if the ignition is sw itched off,
- in side co llisions when the accele ration meas-
ured by the sensor is too low,
- in rear-end col lisions .
A WARNING
-Safety belts and the airbag system will only
p rovide p rotection when oc cupan ts are in
the proper seating position ¢
page 52, Gen­
eral information.
- If the airbag ind ic a tor light~ page 18
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained .

-If you have the impression your engine con­
sumes excess ive amounts of o il, we recom­
mend that you cons ult your Audi dealer to
have the cause of your concern prope rly di­
agnosed. Keep in mind that t he accurate
measurement of oil consumpt ion req uires
great care and may take some time . Your
A udi dealer has instructions about how to
measure oil consumption accurately.
Checking the eng ine oil level
The engine oil level can be checked in the Info­
tainment system

Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0.5 liter per
222
1,000 km). Consumption may be h igher within
the first 3,000 miles (5,000 km).
Because of t his, the engine oil Leve l must be
