Child Safety
The airbag on the passenger side makes the fro nt seat a potentially
d ange rous place for a child to rid e. Th e front seat is not the safest
place for a ch ild in a forwa rd-faci ng child seat . It is a very da ngerous
place for an infant o r a larger child in a rearward-fac ing seat .
& WARNING
Not using a child safety seat, u sing the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a cra sh .
• Never install rearward- facing child safety seats or infant
c arriers on the front passenger seat · even with an Advanced
Airbag System . A child will be seriously injured and can be killed
when the inflating airbag hits the child safety seat or infant carrier
with great force and smashes the child safety seat and child against the backrest, center armrest , door or roof=>
page 192,
"Child restraints on the front seat -some important things to
know".
• Always install rearward-facing child safety seats or infant
carriers on the rear seat .
• Never install a rearward-facing child restraint in the forward·
facing direction . Such restraints are designed for the special needs
of infants and very small children and cannot protect them prop·
erly if the seat is forward-facing .
• If you must install a rearward facing child safety seat on the
front passenger seat becau se of exceptional circumstances and
the PASSENGER AIR BAG
OFF light does not come on and stay on,
immediately install the rearward-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>

Fig. 189 Schematic
overview: installation
of the seat using the
vehicle's safety belt
system
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
feature on the safety belt to prevent the child safety seat
from moving=>
page 225 or install the seat using the
LATCH attachments - Push the child safety seat down with your 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)
=>
page 225.
- If the child safety seat is equipped with a tether strap,
attach it to the tether anchors =>
page 232.
A toddler or child is usually too large for an infant restraint if it is
more than one year old and weighs more than 20 lbs . (9 kg).
Toddlers and children who are older than one year up to about 4 years
old and weigh more than 20 lbs. (9 kg) up to 40 lbs. (18 kg) must
always be properly restrained in a child safety seat certified for their
size and weight=>
page 222, fig. 188 and=> page 222, fig. 189.
The airbag on the passenger side makes the front seat a potentially dangerous place for a child to ride. The front seat is not the safest
place for a child in a forward-facing child safety seat. It is a very
dangerous place for an infant or a larger child in a rearward-facing
sea t.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a collision or other emergency situa­
tion.
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates. 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. ..,

•L_---=C:..:h..:.. i:..: l .=d ~S=-= a..:..f .= e ~ty ~ --------------------------------------------
& WARNING (cont inued)
• 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 whenever 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 backrest and
will strike parts of the vehicle interior. The child can be seriously
injured or killed.
• Never install rearward-facing child safety seats or infant
carriers on the front passenger seat. A child will be seriously injured and can be killed when the passenger 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 rearward-facing child safety seats or infant
carriers on the rear seat.
• Forward-facing child safety seats or infant carriers installed on
the front passenger's seat may interfere with the deployment of
the airbag and cause serious injury to the child.
• It is safer to install a forward-facing child safety seat on the
rear seat.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 215. Special precau­
tions apply when installing a child safety seat on the front
passenger seat=>
page 192, "Child restraints on the front seat -
some important things to know".
& 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 =>
page 201, "Monitoring
the Advanced Airbag System".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on .
• Improper installation of child restraints can reduce their effec­
tiveness or even prevent them from providing any protection.
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child.
• Always carefully follow the manufacturer 's instructions
provided with the child safety seat or carrier.
• Never place additional items on the seat that can increase the
total weight registered by the weight-sensing mat and can cause
injury in a crash .
& 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 restraint up, against or very
near the instrument panel. .,_

Child Safety --------------------"'----
& WARNING (continued)
• 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.
& 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 exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered 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, immediately install the rearward-facing child safety seat
in a rear seating position and have the airbag system inspected by
your authorized Audi dealer. •

a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To acti­
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat .
- Slowly pull the belt
all the way out.
- Route it around or through the child restraint 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 convertible locking
retractor is now activated.
- Make sure that the red release button is facing 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) . .,

Driving and environment
The catalytic converter is an effic ient ''clean-up" dev ice built into the
ex hau st system of the ve hicle. The c ata ly tic converter bu rns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c rit ical ly import ant for the life of
the cata lytic converter and proper funct ioning of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
e xhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fi re.
• Do not apply additional undercoating or rustproofing on or
near the e xhaust man ifold , exhaust pipes , catalytic converte r or
heat shields . During driving, the substance used for undercoating
could overheat and cause a fire.
0 Note
• Be aware that j ust one tank filling with leaded fuel will already
seriously degrade the performance of the ca talytic conve rter.
• Do not exceed the correct engine oil level =>
page 279.
• Do not dr ive until the fuel tan k becomes complete ly empty . The
engine could misfire . Unburned fuel cou ld also get into the exha ust
system and th is cou ld cause the catalyt ic converter to overheat .
• Do not tu rn o ff the igni tion while t he vehi cle is moving.
• Do not contin ue to operate your vehicle under these conditions, as
otherwi se fuel c an reac h the c atal ytic conve rter. This co uld res ult in
overheat ing of the converter, requir ing its replacement.
• T o ass ure eff icient ope ra ti on of the Emiss ion Cont rol System:
- Have your vehicle maintained properly and in accordance with
the se rvice recommendations in your Wa rranty
& M aintenance
booklet. -
Lack of proper maintenance as well as improper use of the
veh icle w ill impair the f unc tion of the emiss io n con trol sys te m an d
co uld lead to damage.
<£> For the sake of the environment
Even when the Emiss ion Control System is operating p roperly, the
exhaust gas can have a s ulfur -like exhaust gas smell under some
operat ing states . This depends on the sulfur content of the fu el being
used. Using a different brand of fuel may help, or filling the tank with
lead -free supe r grade gasoline. •

Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
Th e vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a lar ge exten t on the design of the
facility, the filtering of the wash water, the type of wash and care material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash.
Before going thro ugh a car wash, be sure to take the usual precau­
tions such as closing the windows and the roof. Factory installed
antennas must not be removed.
If you have installed additional accessories on the vehicle -such as
spoilers, roof rack, etc. - it is best to ask the car wash operator if these
should be removed.

The best way to remove snow from windows and mirrors is to use a
brush. Use a non-abrasive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mirrors.
Th e windows must not be cleaned with insect remover or wax since
these can interfere with the function of the windshie ld wipe r blades
(chatter).
Oil , grease, or silicone residue can be removed with
glass cleaner or
silicone remover. However, wax residue requires the use of a specially
formulated solvent . P lease contact your authorized Audi dea le r for
advice on safe products for wax removal.
Windows should also be cleaned on the inside at regular intervals .

-Checking and filling
-------=----- -=-----------------------------------------
For more information about engine oil that has been approved for
your veh icle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa .com or www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform to
Audi oil standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet . Do not exceed these intervals - harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expensive engine repa irs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Adviso r.
Under some circumstances the engine o il should even be changed
more frequent ly. Change oil more often if you drive mostly short
distances, operate the veh icle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freez ing po int for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essentia l that you change yo ur oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to fa ilure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
eng ine components, all inte rnal comb ustion eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 246) consume
more oil dur ing the break- in period than they consume after oil
consumption has stab ilized.
Under normal conditions, the rate of oil consumption depends on the
quality and viscosity of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified . There is no alternative
to regular and frequent checking of the oil level, see
Note .
If the yellow engine oil level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as possible
~ page 279. Top off the oil at your earliest convenience~ page 279.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNINGS ~
& in "Working in the engine
compartment" on page
275.
