restraints on the front seat -some impor­
tant things to know .
A WARNING
Always take special precautions if you must
install a forward or rearward-facing child re­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front pas ­
senger 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 236, Monitoring
the Advanced Airbag System.
- T ake the ch ild restraint off the front passen­
ger seat and install it p roperly at one of the
rear seat positions if the
PAS SEN GER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on .
- Improper installation of chi ld restraints can
reduce their effectiveness or even prevent
them from providing any protection.
- An improper ly installed chi ld restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child .
- Always carefu lly 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 in­
jury in a crash .
A WARNING
Forward-facing child restraints :
-Always make sure the forward-facing seat has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and s ide a irbag .
- Never put the forward-facing child restraint
up, against or very near the instrument pan ­
el.
-Always move the front passenger seat to
the highest position in the up and down ad-
Ch ild safety
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
adjustment range, as far away from the air­ bag as possible , before installing the for­
ward-facing child restraint.
- Always make sure that the safety belt upper
anchorage is behind the ch ild restraint and
not next to or in front of the child restraint
so that the safety be lt will be properly posi­
tioned.
- Make sure that the
PASSENGER AIR B AG
OFF
li ght comes on and stays on a ll the time
wheneve r the ignit ion is switched on.
A WARNING
Rearward-facing ch ild restraints:
- A child in a rearward-fac ing ch ild safety sea t
installed on the front passenger seat will be
serio usly injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating airbag will h it the ch ild safety
seat or infant carrier with great force and
will smash the child safety seat and child
aga inst the backrest, center armrest, door
or roof.
- Always be especially carefu l if you must in­
stall a rearward facing child safety seat on
the front passenger seat in except iona l cir­
cumstances.
- A t ight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight-mat in the seat and reg ister a heav i­
er weight in the Advanced Airbag System .
The heavier weight reg istered can make the
system work as though an ad ult we re on the
seat and deploy the Advanced A irbag when
it must be suppressed causing serious or
even fata l injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
whenever the ignition is switched on .
- If the
PASSENGER AIR BAG OFF li ght does
not come on and stay on, immediately in­
stall the rear-facing child safety seat in a rear seating posit ion and have the airbag
system inspected by your Audi dealer.

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages.
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
" L ower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" w ith "lower uni­
versal anchorages" (or "lower universal anchor­ age bars") are used to describe the system.
In other countries the term ''ISO FIX" is used to
describe the lower anchorages .
Forward-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 seats.
Installing a child restraint that requires a top
tether without one can serious ly impair the per­
formance of the chi ld restraint and its ability to
protect the child in a collision. Installing a child
restraint that requires a top tether without the
top tether may be a v iolation of state law.
Ch ild restraint manufacturers offer LATCH lower
anchorages on the ir ch ild seats with hook-on or
Child safety
push-on connectors attached to adjustable
straps.
In addition to the LATCH lower anchorages, these
child rest raint systems usua lly require the use of
tether straps to help keep the child restraint
firmly in place.
A WARNING
-
Improper installation of child restraints will
in crease the risk of injury and death in a
crash.
-Always follow the instructions provided by
the manufacturer of the child restraint you
intend to insta ll in your vehicle.
- Never install a child restraint without a
proper ly attached top tether strap if t he
child restraint manufacturer's instructions
require the top tether strap to be used.
- Improper use of child restraint LATCH lower
anchorage points can lead to injury in a colli­
sion. The LATC H lower anchorage points are
des igne d to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchorage point.
- Never secure or attach any luggage o r other
item to the LA TCH lower anchorages.

Lower anchorages secure the child restraint in
the seat without using the vehicle's safety belts .
Anchorages provide a secure and easy-to -use at ­
tachment and m inim ize the possibility of improp­
er ch ild rest raint insta llation .
All child restraints manufactured after Septem­
ber 1, 2002, must have lower anchorage attach ­
ments for the
LATCH system .
Remember that the lower anchorage points are
only intended for installation and attachment of
262
child restraints specifically certified for use with
LATCH lower anchorages. Child restraints that
are not equ ipped with the lower anchorage at­
tachments can still be installed in compliance
with the chi ld restraint manufacturer's instruc­
tions on us ing vehicle safety be lts .
_& WARNING
Imp roper use of LATCH lower anchorages can
cause ser ious persona l injury in an accident.
-Always carefully follow the ch ild restraints
manufact urer's ins tructions for proper in­
stallation of the child restraint and prope r
use of the lower an chor ages or safety belts
in your vehicle .
- Never secure or attach any luggage or othe r
items to the

.,. Remove the child restraint according the child
restraint manufacturer's instructions.
.,. Push down on the seat cushion so that the low ­
er anchorages are visible .
.,. Pull off the guidance fixtures from the lower
anchorages.
.,. Always remove the guidance fix tures and keep
them in a safe p lace when not in use.
You may find it easier to install ch ild restraints
eq uipped w ith hooks attached to st raps without
the guidance f ixt ures in place. If th is is t he case,
remove the guidance fixtures by pu lling them off
the anchorages . However, the guidance fixtures
can help you to locate the
LATCH anchorages.
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
c> page 58. Th e child safety seat as well as
the rear seat can be damaged by the adjust­
ment process.
Tether anchors and tether straps

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

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 '<t
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

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) .

After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.

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.

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
