use of a forwa rd-facing child restraint on
the front passenger's seat, the ch ild's safe­
ty and well-being require that the follow­ ing special precautions be taken :
- Make sure the forward-facing seat has
been designed and certif ied by its manu­
facturer for use on a front seat with a
passenger front and side a irbag.
- Always follow the man ufacturer's in­
struct io ns provided with the child safety
seat or infant car rier .
- Always move t he front passenger seat in­
to the rearmost posit ion of the passen ­
ger seat's fore and aft ad justment range,
and as far away from th e airbag as possi­
ble before ins tall ing the child res traint .
- Always make su re that noth ing prevents
the front passenger's seat from bei ng
moved to the rearmost posi tion in its
fore and aft adjus tme nt r an ge.

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 re tractor to properly secure child
safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
fro nt passenger's seat safety belt have a con­
vertible locking retracto r for child restra ints .
The safety belt must be locke d so that belt
webbing can not unreel. The ret ractor ca n be
activ ated to lock the safety be lt and p revent
the safety belt webbing from loosening up
d ur ing normal driv ing . A child sa fe ty seat can
on ly be proper ly installed whe n the safety belt is loc
ked so that the chi ld and child sa fety
seat wi ll stay in place.
Alw ays remember: Even tho ugh yo ur vehicle is
equipped wi th an A dvan ced Airbag system, all
c hi ldren, especially those 1 2 years and young ­
er, sho uld always ride in the back seat prope r­
l y restra ined fo r the ir age and size.
A WARNING
Improperly installed ch ild 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 insta lling a child
safety seat. A n un locked safety belt re­
trac to r cannot hold the child safety seat
in place dur ing norma l driving o r in a
crash.
- Always buckle the child safety seat firmly
in place even if a ch ild is not si tt ing in it.
A loose child sa fe ty se at can fly aroun d
du ring a s udden stop or in a collision .
- Always make sure that the rear seat
backres t to wh ich the center rear safety
belt is attached is securely latched when ­
eve r the rea r center safety belt is being
used to secure a ch il d restra int .
- If the backrest is not securely la tc h ed,
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 ca rr ie rs o n the front pas­
senger seat . A child will be serious ly in­
jured and can be killed when the passen­

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

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 airbag as possible before installing
the forward-facing child restraint . The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
A WARNING ...==-
Rearward-facing child restraints:
-A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates -
even
with an Advanced Airbag System.
- 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 be especially careful if you must
install a rearward facing child safety seat
on the front passenger 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 regis­
ter a heavier weight in the Advanced Air­
bag System. The heavier weight regis­
tered can make the system work as •

though an adult were on the seat and de­ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child .
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your Audi dealer.
Activating the convertible locking retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor:
"" Place the child restraint on a seat, prefera­
bly on the rear seat.
""Slowly pull the belt
all the way out.
""Route it around or through the child re­
straint belt path¢&_ .
"" Push the child safety seat down with your
full weight to get the safety belt really tight.
"" Insert the belt tongue into the buckle for
that seating position.
""Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat.
""You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt 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 more
than one inch (2.5 cm).
A WARNING ....__ -
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- 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 crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation.

temperature. This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumpt ion while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various e lectrica l compo ­
nents . Data from battery diagnosis is consid­
ered.
D epending on the battery's state of charge,
individua l consumers are gradua lly turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy management
While the veh icle is being driven, dynamic en­
ergy management dist ributes the energy gen­
erated according to the needs of the individu­
a l components . It reg ulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If starting ab ility is threatened, the indi­
cator light (•) appears
c> page 16, Cl
Battery .
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 electrical energy is re­
qu ired, but only a little is generated. It is also
cr itica l if the engine is not running and electri­
cal components are turned on. In th is in­
stance energy is being consumed but none is
be ing generated .
Intelligent technology 203
It is in precisely these situations that you will
notice energy management active ly regu lat­
ing the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectrica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capability over a longer period.
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustment. The convenience
functions will be available again when you
switch on the ignition and start the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged.
If starting capability is jeopardi zed due to en­
ergy consumption , the following warning ap­
pears in the MM I display:
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes. If
you w ish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical 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 great
deal consumed and the battery's state of
charge is not optimal.
T o b ring the energy ba lance back into equili­
brium , consumers wh ich requ ire espe cially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice, for examp le, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched .,.

206 Driving and en vir onm ent
Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
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 i=> page 220,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 234, Adding engine oil .. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or 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 shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will al ready seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 234.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
Cl symbol for the diese l
particulate filter i lluminates
i=> page 21. ..,.

You must drive your vehicle about 3,000 miles (5,000 ki lometers) before you can properly
assess o il consumption.
This also applies to fuel consumption and en­
gine output.
(D Note
- Have yo ur vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System
and other important veh icle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold engine .
The engine and catalyt ic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively.
Just after starting, a cold engine in a mid-size
car only 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). Afte r abo ut
2.5 m iles (4 km),
the eng ine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips whenever possible.
Driving and environment 209
The outside temperature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.

Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft mi­
crofiber cloth.
Rinse the vehicle tho roughly again and let it
air dry. Remove any water residue using a
shammy .
A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents .
- To reduce the risk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the wheel housings .
- After washing the vehicle, the braking ef­
fect may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applicat ions.
- If you wash the vehicle in an automatic car wash, you must fold the exterior m ir­
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior m ir- rors* must only be fo
lded in and out us­
ing the power folding fu nction .
- T o prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r is k of damage to the sur­
face, do not use insect removing spong ­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply
protective wax. It can destroy the
matte fin ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
a re removed.
@ For the sake of the environment
Only wash the vehicle in facilities spec ially
designed for that p urpose . This will red uce
the r is k of dirty wate r contam inated with
oil from entering the sewer system.
