-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 in exceptiona l circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immed iately
install the rear-facing child safety seat in
a re ar seating posit ion and have the air­
bag system inspec ted immediately by
yo ur Audi dealer.
_& WARNING
If, in exceptional circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always make su re the forward-fac ing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the man ufacturer's in­
struct ions provided with the child 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 a irbag as poss ible before installing
the ch ild restraint. The backrest must be
adjusted to an upr ight position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
Advanced front airbag system and
children
Your vehicle is equipped with a front "Ad ­
vanced A irbag System" in compliance wit h
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as app licab le at the
time your veh icle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the " low-risk" re­
qu irements for 3- and 6-year old ch ildren on
the passenger s ide and small adults on the
driver side . The low risk deployment criter ia are intended
to red uce the risk of in jury
thro ugh interaction with the airbag that can
occur, for examp le, by being too close to the
steering wheel and instrument panel when
the a irbag inflates. In addition, the system
has been certified to comply with the "sup ­
pression" requirements of the Safety Stand­
ard, to turn off the front a irbag for infants up
to 12 months who are restrained on the front
passenge r seat in child restra ints that are list­
ed in the Standard .
Even though your veh icle is equipped with an
Advanced Airbag system, a ll children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly res trained
for their age and size . The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a ch ild to ride . The front
seat is not the safest p lace for a child in a for­
ward-fac ing ch ild safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-fac ing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in you r vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us ­
ing the weight-sens ing mat in the seat cush­
ion 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 child safety seat and a ch ild blanket on the front passenger
seat. The we ight on the front passenger seat
is related to the design of the ch ild restraint
and its "footp rint", the s ize and shape of the
bottom of the child res traint as it sit s on the
seat. The weight of a ch ild restra int and its
"footprint" vary for different kinds of child re­
straints and for the different mode ls of the
same kind of chi ld restraint offered by ch ild
restraint manufacturers.
T he weight ranges fo r the individual types,
makes and models of child restraints that the .,._

Child safety seats
Infant seats
Babies and infants up to about one year old
and
20 lbs . or 9 kg need special rearward-fac­
ing child restraints that support the back,
neck and head in a crash.

so that the seat cannot
move forward or
sideways more than one inch (2.5 cm).
Infants up to about one year (20 lbs. or 9 kg)
are best protected in special infant carriers
and child safety seats designed for their age
group. Many experts believe that infants and
small children should r ide only in special re­
stra ints in wh ich the child faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash

Installing a child safety
seat
· Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger can be locked with the convertible locking retractor to properly secure child
safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
front passenger's seat safety be lt have a con­
vertib le locking retractor for child restraints .
The safety belt must be locked so that be lt
webbing cannot unreel. The retractor can be
activated to lock the safety belt and prevent
the safety belt webbing from loosening up
during normal dr iving . A child safety seat can
o n ly be properly instal led when the safety belt
is locked so that the chi ld and child safety
seat w ill stay in place .
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
child ren, especially those 12 years and young­
er, shou ld always r ide in the back seat prope r­
ly restrained for the ir age and size.
A WARNING
Improperly installed chi ld safety seats in ­
crease the risk of serious personal injury
and death in a co llision. -

-Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat
in place during normal driving or in a
crash .
- 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 make sure that the rear seat
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
- If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rear-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger airbag inflates .
- 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 or infant carriers on the rear seat.
- Forward-facing child safety seats or in­
fant carriers installed on the front pas­
senger's seat may interfere with the de­
ployment of the airbag and cause serious
injury to the child.

A WARNING
-
Always take special precautions if you
must install a forward or rearward -facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward -facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF
light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described

toring the Advanced Airbag System.
- Take the child restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on.
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child .
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier .
- Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash.
A WARNING
Forward-facing child restraints:
- 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 re­
straint up, against or very near the in­
strument panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from •

the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PAS SENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
A WARNING , _
Rearward-fac ing ch ild restra ints:
- A ch ild in a rearward-facing child safety
seat installed on the front passenge r
seat will be ser iously injured and can be
killed if the front airbag inflates -even
with an Advanced Airbag System.
- T he inflating a irbag will hit the child
safety seat or infant carrier with g reat
force and w ill smash the ch ild safety seat
and child against the backrest, center
armrest, door or roof .
- Always be especially caref ul if you must
install a rearward facing child safety seat
on the front passenge r seat in exception ·
al circumstances .
- A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and reg is­
ter a heavier weight in the Advanced A ir­
bag System. The heav ier we ight regis­
tered can make the system work as
though an adult were on the seat and de­ ploy the Advanced Airbag when it must
be s uppressed causing ser ious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BA G
OFF
light comes on and stays on all the
time whenever the ignition is switched on.
- If the

.,. You should hear a "clicking" noise as the
be lt winds back into the inertia ree l. Test the
convert ible lock ing retractor by pulling on
the belt . You shou ld no longer be able to
pull the be lt out of the retractor. The con­
vertible locking retractor is now activated .
.. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly.
.,. Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways mo re
than one inch (2.5 cm).
A WARNING
-
Using the wrong child restraint or an im­
p roperly installed chi ld restraint can cause
serious personal injury or death in a crash.

tractor is locked when insta lling a child
safety seat . An un locked safety belt re­
tractor cannot hold the child safety seat in place dur ing norma l dr iving or in a
crash.

196 Intelligent technology
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electr ical energy is re­
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not run ning and elect ri­
cal components a re turned on. In th is in­
stance energy is being consumed but none is be ing generated .
I t is in precisely these situations that you w ill
notice energy managemen t actively regulat ­
ing the distrib ution of energy.
Vehicle stands for an ext ended period
If you do not drive your vehicle over a period
of severa l days or weeks, elect rical compo­
nents are grad ually cu t back o r switched off .
This reduces energy co nsu mption and main­
tains starting cap abili ty
over a longer period.
Be aware that when you unlock you r vehicle,
some of the conve nience funct ions may not
ope rate, such as the Convenience key , the re­
mote cont ro l or the power seat adjustment .
The convenience functions will be availab le
aga in when you switch on the ignition and
start the engine .
With the engine turned off
If yo u lis ten to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to e n­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Please start th e engine soon or th e syst em
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inu tes .
If
you wish to cont inu e us ing the functions , you
have to start the engine.
With the engine running
Although e lec trical energy is generated when
the vehicle is being driven, the battery can be ­
come discharged. This happens mostly when
li ttle energy is being generated and a g reat
deal consumed and the battery's state of
charge is not optimal.
To b ring the energy ba lance back into equili­
brium, consumers which req uire especially
l arge amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems i n par­
ticular require a great deal of energy. If you
notice , for example, that the heated seats* o r
the heated rear window are not heating, they have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engi ne idle speed has
been increased slightly . Thi s is normal and not
a cause for con ce rn. By inc reas ing eng ine id le
speed the addi tional energy requ ired is gener­
ated and the battery is charged.

198 Driving and en vi ro nment
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 218,
Fuel supply.
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 22 7, Adding engine oil 't=r. .
• Never try to push- or tow-star t your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the l ife of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shie lds . During driving, the
substance used for undercoating could
overheat and caus e a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the perfo rmance of the catalytic
conve rter .
- Do not exceed the correct engine oil leve l
¢page 227.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . Un burned f uel could a lso get into the exhaust system and th
is co uld cause
the cata lytic converter to overheat .
- Do not switch
off the ignition while the
vehicle is moving .
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control Sys tem is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke ex haust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is es peci ally true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .
