A WARNING
Improper use of tether anchorages or lower
anchorages can cause serious persona l injury
in a crash .
- Always carefully follow the child restra int
manufacturer's instruct ions for proper in­
stallation and use of child restra int systems .
- Never use the
LATCH or tether anchorages
to attach safety belts or other kinds of occu­
pant restra ints.
- Child restra int tether attachments and low­
er attachments are only designed to secure
a ch ild restraint that has been equipped to
use these anchorages .
-
Child sa fety
- Tether anchorages and lower anchorages
are designed to withstand only those loads
imposed by correctly fitted child restraints.
Under no circumstances can they be used
safely for adu lt or ch ild safety belts or har­
nesses.
- Never mount more than one child restraint to a sing le tether or to a lower anchorage
point. Attaching two child restra ints to a
sing le anchorage point can cause the an­
chorage to fail and cause serious personal
i n ju ry in a crash.
(D Note
- Remove the guidance f ixt ures before fo ld­
ing the rear seatback to preven t damag ing
the seat cushion .
- T o attach the c hild rest raint securely, the
sea t must be moved to the farthest rear po­
sition, the seat heigh t set to the lowest po­
sition and the head restraint must be ad­
justed to the vertical position.
- If you leave the guidance fixtures i nstalled
for several days, they cou ld leave a mark on
the upholstery on the seat cushion and backrest in the area that the guidance fix­
tures were installed. The upholstery would
also be permanently stretched around the
guidance fixtures. Th is applies especially to
leather seats.

death in an accident .
- Th ese anchors were deve loped only for child
safety seats using the "LA TCH" system.
- Never attach other child safety seats, belts
or other objects to these anchors .
- Always make sure that you hear a click when
latch ing the seat in place. If you do not hear
a click the seat is not secure and could fly
forward and hit the interior of the vehicle,
or be ejected from the vehicle .
.,&. WARNING
Improper installation of child restraints will
increase the risk of injury in an acc ident.
- Always follow the child restraint system
manufacturer's instructions for proper in­
stallation of the child restraint system and
proper use of tether straps as well as the
lower anchorages or safety belts in your ve­
hicle .
- Always read and heed the important infor­
mation and WARNINGS about child safety
264 and the installation of child restraint sys­
tems

(D Note
On vehicles with power adjustable rear seats*
some crite ria must be observed when attach­
ing the child restraint using the
LATCH sys­
tem:
- To attach the ch ild restraint securely, the
seat must be moved to the farthest rear po­
sition, the seat height set to the lowest po­
sit ion and the head restraint must be ad­
justed to the vertical position.
- If a child safety seat is attached to one of
the rear seats, this seat must not be adjust­
ed using the power controls under any c ir­
cumstances. The
Entry assistance for this
seat must also be deactivated in the MMI

the rear seat can be damaged by the adjust­
ment process.
Tether anchors and tether straps
Fig. 251 Tether ancho rs: recess flaps behind the rear seat­
backs
The tether anchors for the two* /three rear seat­
ing positions are located in recesses in the rear
window shelf
c> fig . 251 . Vehicles with two rear
seat ing positions* are equipped with two tether
anchors .
A tether is a straight or V-shaped strap that at­
taches the top part of a chi ld restraint to special
anchorage points in the veh icle.
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury

rior .
Fo rward facing child restraints manufactured af­
ter September 1, 1999, are required by U .S. fed­
eral regulations to comply with new child head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child safety seats.
A WARNING
Improper installation of child restraints will
increase the risk of injury and death in a
crash.
- Always follow the instructions provided by
the manufacturer of the child restraint you
intend to install in your Audi.
- Improper use of child restraint anchors (in­
cluding tether anchors) can lead to injury in
a collision. The anchors are designed to
withstand only those loads imposed by cor­ rectly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchor point.
- Never attach two child restraint systems to
one tether strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether anchorages
to secure safety belts or other kinds of occu­ pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If a tether or other strap is used to attach a
child restraint 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.
- The heavier weight registered can make the
Advanced Airbag System work as though an adult were on the seat and deploy the Ad­
vanced Airbag when it must be suppressed causing serious or even fatal injury to the
child.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the

Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
please go to the official website
(www.toptiergas .com) .
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a min imum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fuel will slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gasol ine may not be available.
For more information on refueling your vehicle,
see
~ page 268.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore , buy ing
the correct grade of gasoline is very important to
h e lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat-
~ ings that can usually be found on the filler pump: .... N
~ -Premium Grade: 91 -96 AKI .... 0 0 :c ' Checking and Filling
-Regu lar Grade: 87 -90 AK I
Exp lanation of the abbreviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Moto r Octane Number.
(D Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not us e leaded gasoline. The use of lead­
ed gasoline will severe ly damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AK I or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur-
ing seasonal change-over, we suggest that you ..,.
267

Checking and Filling
fill up at busy gas stations where the seasonal
adjustment is more likely to be mad e in time.
0 Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A pp lies to: ve hicles w ith gasoline engine
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
268
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.
([) Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
Refueling
· Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
~ page 2 70.
You can find the fuel tank capacity of your vehicle
in
~ page 334 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 267.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
& WARNING
-Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/AS TM F8S2 -86).

C) C0 ....
"' ,....
"' .... 0 0 :r (D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

ti l it latches .
Checking and Filling
Once the pump nozzle switches off, the fuel tank
is "full". Do not fill the tank more . Otherwise the
expansion space in the tank will be filled.
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see
c:!;> page 267.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section c:!;> page 334.
To avo id fuel spilling or evaporat ing from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp
c:!;> page 25 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
-
-If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
completely into the tank opening, fuel can
leak out or run over. Leaked fuel can ignite
and start a fire.
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling. If
you must make an exception and enter your
veh icle aga in while fueling, close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
269

Checking and Filling
-Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion .
- Always place a fuel container on the
ground before filling .
- Always hold the fuel nozzle completely in
the fuel container when filling .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing.
- Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death.
- Follow legal requirements when using,
storing and transporting fuel containers.
- Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
0 Note
- Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty . The irregular supply of fuel that re­
sults from that can cause engine misfires .
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
