position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a s ubst itute for yo ur
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you 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 soc::,
page 122, Gener ­
al information.
Remember too, airbags will deploy only once and
only in certain k inds of accidents -your safety
be lts
a re always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have a lready dep loyed, for
examp le when yo ur vehicle str ikes or is str uck by
anothe r afte r the f irst collis ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The a irbag
sys tem wo rks most effec tively when used with
the safety belts. Therefore , al ways wear your
safety bel ts cor rect ly .
It is important to remember that while the sup­
p lemental knee a irbag sys tem is designed to re­
d uce the like lihood of serious injur ies, other inju­
ries, fo r example, swell ing, b ruising, and m inor
abrasions and fr iction burns can also occu r when
an airbag inflates.
The kne e airbag system basically consists of:
- The electronic contro l modu le
- Two inf latab le airbags (airbag and gas genera-
tor), one for the dr ive r and one fo r the front
passenge r
- T he airbag ind icator light in the instrument
pane l

the airbag will inflate when it is not sup­
posed to, or w ill not inflate w hen it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully deployed knee airbags.

ger dep loy in certain but not all fronta l co llisions.
If t he front airbags deploy, the knee a irbags also
deploy in frontal coll is ions when t he deploy ment

GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
ward-facing child safety seat in a rear seat­
ing posit ion and have the airbag system in­
spected immediately by your authorized
Audi dealer.
A WARNING
If, in except ional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat :
- Always make sure the forward-fac ing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and s ide airbag .
- Always follow the manufac turer 's instruc­
tions provided with the chi ld safety seat or
carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le before installing the child
restra int. The backrest must be adjusted to
an upr ight position.
-Always make sure that the
PA SSENGER AIR
B AG OFF
light comes on and stays on all the
t ime whenever the ignition is switched on.
Always replace ch ild restraints that were in­
stalled in a vehicle dur ing a crash. Damage to
a child restraint that is not visib le could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your veh icle is equipped with a front "Advanced
A irbag System" i n compliance w ith United States
F edera l Moto r Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Ve hicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured .
The Advanced Airbag system in your ve hicle has
been ce rtified to meet the " low-risk" requ ire­
ments for 3 -and 6-yea r old children on the pas ­
senger side and sma ll adults on the driver side .
Child safety
The low risk deployment criteria a re intended to
reduce the risk of injury through interaction with
the a irbag that can occur, for example, by be ing
too close to the steering wheel and instrument panel when the airbag inflates. In addition, the
system has been certified to comply with the "suppression" requirements of the Safety Stand·
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas­
senger seat in ch ild rest raints that are listed in
the Standard.
Even though your veh icle is equipped with an Ad·
vanced Airbag system, all ch ild ren, especially
those 12 yea rs and you nger, sho uld a lways ride
in the back seat proper ly restrained for their age
and size . The airbag on the passenger side makes
the front seat a potentially dangerous p lace for a
child to ride. The front seat is not the safest place
for a ch ild in a forward-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat .
' Advanced Airbags and the weight-sensing
mat in the front seat
The Advanced A irbag System in your vehicle de ­
tects the presence of an infant or chi ld in a chi ld
restraint on the front passenger seat using the
weight -sensing mat in the seat cushion and the
sensor below the safety belt latch on the front
passenger seat that measures the tens ion on the
safety belt.
The weight-sensing mat measures total weight of the child and the chi ld safety seat and a child
blanket on the front passenger seat . The weight
on the front passenger seat is related to the de­
s ign of the child restra int and its "footprint", the
s ize and shape of the bottom of the ch ild re-
straint as it sits on the seat. The weight of a ch ild
restra int and its "footprint" va ry for different
k inds of child restra ints and for the different
models of the same kind o f chi ld rest raint of -
fered by chi ld restraint manufacturers.
T he we igh t ranges for the indiv id ual types,
makes and mode ls of ch ild restraints that the
NH TSA has specified in the Safety Standard to­
gether with the weight ranges of typical infants .,.

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the veh icle, especially children:
gi .,. Always use the right chi ld safety seat for each ......
~ child and a lways use it properly qpage 155. N ...... 0

LL 00
Child safety
.,. Always carefully follow the chi ld safety seat
manufacturer's instructions on how to route
the safety belt properly through the ch ild safe ­
ty 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 chi ld safety seat from moving
q page 159.
.,. Push the ch ild safety sea t down with yo ur 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 .
.,. Secure unused safety belts on the rear seat
q page 155.
Always remember: Even though your veh icle is
equipped with an Advanced Airbag system, all
c hi ldren, especia lly t hose 12 yea rs and younger,
sho uld a lways ride in th e back seat p roper ly re·
strained for their age and s ize.
A WARNING
=
Not using a child safety seat, using the wrong
chi ld safety seat or improperly insta lling a
chi ld restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must always be restrained properly whenev­
er riding in a vehicle.
- An unrestra ined o r improperly restrained
c hi ld can be injured o r killed by being
thrown aga inst the inside of the veh icle or
by being ejected from it during a sudden
maneuver or impact.
- An unrestra ined or improperly restrained
child is at much greater risk of injury or
death by being struck by an inflating air­ bag.
- Commercially availab le child safety seats
are requi red to comply with U .S. Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213). ..,_

Child safety
-When buying a child restraint, select one
that fits your child and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames . They do not pro­
vide adequate contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety belt.
They must always be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents.
- Never let more than one child occupy a child
safety seat.
- Never let babies or older children ride in a
vehicle while sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rearward-facing child safety
seats or infant carriers on the front passen­
ger seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates -even with an Advanced Airbag Sys­
tem .
- The inflating airbag will hit the child safe­
ty seat or infant carrier with great force
and will smash the child safety seat and
child against the backrest, center arm
rest, door or roof.
- Always install rearward-facing child safety
seats or infant carriers on the rear seat.
154
-Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child . Always install for­
ward-facing child safety seats on the rear seat .
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require that the following
special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer for use on a front seat with a pas­
senger front and side airbag .
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat into
the rearmost position of the passenger
seat's fore and aft adjustment range, and
as far away from the airbag as possible be­
fore installing the child restraint.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
- Always make sure that the backrest is in
the upright position.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used¢

Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for s tarting the engine.
If a veh icle wit h a conventional energy system is
not driven for a long per iod of t ime, the battery is
d ischa rged by idling current consumers (e.g. im­
mo bilizer). In cert ain cir cums tan ces it c an result
i n there be ing insuff ic ient ene rgy available to
start the engine.
I ntell igen t energy management in your veh icle
h andles the distr ib ution of ele ct ric al ene rgy.
S tarting ab ility is mar ked ly imp roved an d the l ife
of the batte ry is extended.
B asically, e nergy management consis ts of
bat­
tery diagno sis, idling curr ent management
and
dynamic energy management .
Intelligent Technology
Battery diagnosis
Battery diagnos is con tinuously dete rmi nes the
state o f the bat tery . Sensors determine battery
vo ltage, battery c urrent and batte ry tempera­
tu re. This determines t he current state of charge
and the power of the battery.
Idling current management
Id ling cur rent management reduces ene rgy con­
s u mption whi le the vehicle is standing . With the
ignition switched off, it contro ls the energy sup­
ply to the vario us electrical components . Data
from battery d iagnosis is cons idered.
Depend ing on the ba ttery's s tate of charge, indi ­
vidual consumers are gradually turned off to pre­
vent excess ive discharge of t he battery and thus
mainta in starting capab ility.
Dynamic energy management
While t he vehi cle is being d riven, dynami c energy
management dis trib utes the energy generate d
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical e nergy is not being used than is being
generated and ensures an opt imal state of
charge for the battery .
(i) Tips
-But even ene rgy management cannot neg­
ate the lim its of physics. Consider that the
powe r and life of a battery are lim ited.

What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severe ly taxed in short-distance
driv ing, in city traffic and dur ing the cold time of
year. Abundant e lectrica l energy is required, but
o n ly a little is generated. It is also c ritical if the
engi ne is not running and electrical components
are tu rned on . In this instance energy is being
co nsumed bu t no ne is being ge nerated. .,,.

Driving and th e en vironm ent
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.,. Have your vehicle serviced at regular intervals.
By having your vehicle regu larly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and econom ically . The condition of
your veh icle not only affects its safety and ability
to hold its value, it also affects
fu el consump­
tion .
C he ck your oil e ach t ime you fill you r ta nk .
The amount of oil used is re lated to engine load
and speed.
It is normal for the oil consumpt ion of a new en­
g ine to reach its lowest val ue afte r a certa in mile­
age has been driven .
You must d rive you r vehicle about 3 ,000 miles
(5,000 k ilome ters) before you can p roperly as ­
sess o il cons umption .
This a lso applies to fuel consumption and engine
outpu t.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in you r Warranty

- Do not a lter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.

Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid driving short distances with a cold
eng ine .
T he eng ine and catalytic converter have to reac h
their opt imal
operating temper atu re to reduce
fuel consumpt ion and noxious emiss ions effec­
tively .
Just after start ing, a cold engine in a mid-size car
on ly achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . After about
2 .5 m iles (4 km), the engine is
at its proper operating temperatu re and fuel
economy has reached a no rma l level. So you can
see that you should avoid sho rt tr ips wheneve r
possible .
The
out sid e temperatur e is also cr it ica l in th is re­
gard. Your car cons umes more fue l in the winter
than in the summer.
