& 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 .
• All vehicle occupants and especially children must always be
restrained properly whenever riding in a vehicle .
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the vehicle or by
being ejected from it during a sudden maneuver or impact.
- An unrestrained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag.
• Commercially available child safety seats are required to
comply with U.S. Federal Motor Vehicle Safety Standard (FMVSSI
213 (in Canada CMVSS 2131.
-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 cushion. The child restraint must not tip or
lean to either side . Audi does not recommend using child safety
seats that rest on legs or tube-like frames. They do not provide
adequate contact with the seat .
- Always heed all legal requirements pertaining to the installa ­
tion and use of child safety seats and carefully follow the
instructions provided by the manufacturer of the seat you are
using.
• Never allow children under 57 inches (1.5 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 maneuvers or
accidents.
• Never let more than one child occupy a child safety seat .
& WARNING (continued)
• 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 substitute for a child
restraint system .
- The strongest person could not hold the child with the forces
that exist in an accident. The child will strike the interior of the
vehicle and can also be struck by the passenger.
- The child and the passenger can also injure each another in
an accident.
• Never install rear-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 - 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 arm rest, door or roof .
• Always install rear -facing child safety seats or infant carriers on
the rear seat .
• 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 forward-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 precau ­
tions be taken :
- 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.
- Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.

& WARNING (continued)
• 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 rear-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 arm rest, door or roof.
• Always install rear-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 210. Special precau­
tions apply when installing a child safety seat on the front
passenger
seat => page 189, "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.

Child Safety
& WARNING (continued)
• If the PASSENGER AIR BAG OFF light does not come on and stay
on, perform the checks described
=> page 198, "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 .
• 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 arm rest, 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 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 secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint in your vehicle. To
activate 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).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.

Cleaning and protection -
------------~---
High temperatures, as from exposure to intense sunlight, intensify
the corrosive effect particularly when humidity is high as well.
Under certain circumstances,
weekly washing may be necessary.
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and the information
~ page 254 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The 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 large extent 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 through a car wash, be sure to take the usual precau­
tions such as closing the windows and power roof* . Remove
antenna if applicable.
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.
& WARNING
Always read and heed all WARNINGS and the information
=> page 254. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
- Before you start washing, make sure you have read and
understood the
WARNINGS=> & in "General informa­
tion" on
page 254 .
- First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door sills and other
regions exposed to pick up road dirt. In this way, you will not
scratch the paint with coarse particles imbedded in the sponge the
next time you wash the car.
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms . You may cut yourself on sharp-edged metal parts.

Ap plies to veh ic les: with Fab rics an d fabric cove rings
Fabrics and fabric coverings
Fabrics a nd fabr ic coverings (e .g. seats, doo r tr im panels, etc .)
shou ld be c leaned at regular intervals with a vacuum cleaner. This
re moves surface d irt part ic les which could become embedded in
the fabric through use . Steam cleaners shou ld not be used, because
the steam tends to push the dirt deeper into the fab ric a nd lock it
there .
Norm al cleaning
Genera lly, we recommend using a soft sponge or a lint -free
m icrof iber c lo th to the clean fabric . Brushes should on ly be used for
carpets and floor mats, since other fabric surfaces could be harmed
by brushes.
Norma l sur face stains ca n be cleaned us ing a commercially ava il­
able foam cleaner. Spread the foam on the surface of the fabric with
a soft sponge and work it in ge ntly . Do not saturate t he fabr ic. Then
pat the foam dry us ing absorbent, dry cloths (e .g . microfiber cloth)
a n d vacuum i t after it has dr ied comple tely.
Cleaning stains
Stains caused by beverages (e .g. coffee, fru it ju ice, etc.l can be
treated with a mild detergent solution. Apply the detergent so lution
with a sponge . In the case of stubborn stains, a de tergen t paste can
be applied direct ly to the stain and worked into the fabric . After ­
wards, use c opious a mounts of c lean water to rem ove the
remaining detergent . Apply the water with a damp cloth or sponge
a n d pat the fabric dry with an absorbe nt, dry c loth .
Stains from choco late or makeup should have detergent paste (e .g.
ox -ga ll soap) rubbed into them. Afterwards, remove the soap with
water (damp sponge).
A lcoho l can be used to treat stains from grease, oi l, lipstick or a ba ll­
point pen . Melted grease or dye must be patted off us ing abs orbent
material. It may be necessary to retreat the areas with detergent
paste and water . .,,,

prevent the formation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive repairs.
At the time of printing, engine oils available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
condi tions where you drive. You can use oil wi th a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions .
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the oil while on the road.
Only if the level of the oil is at or below the minimum mark on the
oil dipstick -and no oil that expressly conforms to Audi oil standard
VW 502 00 specifications is available - may you top off with a high
quality engine oil, preferably synthetic -based , that meets ACEA A3,
ACEA A5 or ACEA B5, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40 .
However, during the entire time between oil change intervals, never top off with more than a total of 0
.5 qt/liter engine oil that does not
conform to Audi oil specification VW 502 00.
For more information about engine oil that has been approved for
your vehicle, 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
Maintenance & Warranty booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
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 Advisor.
Under some circumstances the engine oil should even be changed
more frequently . Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point 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 essential that you change your 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 failure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance & Warranty booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
.,_
