Tether anchors and tether straps
Fig. 174 Te the r ancho rs: att achm ent hook locatio ns be­
hi nd the rea r seatbacks
The tether anchors for the two/three* re ar seat­
ing positions are located on the backside of the
rear seatbacks
¢ fig. 174. Vehicles with two rear
seating positions are equipped with two tether
anchors.
A tether is a straight or V-shaped strap that at ­
taches the top part of a child restraint to special
anchorage points in the vehicle.
The purpose of the tether is to red uce the for­
ward movement of the child restraint in a crash,
in order to he lp reduce the risk of head injury
that could be caused by striking the vehicle inte­ rior .
F orward 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 restra int you
intend to install in your Aud i.
- Improper use of child restra int anchors (in­
cl uding tethe r anchors) ca n l ead to inj ury in
a collision. The anchors are designed to
withstand only those lo ads imposed by cor­
rectly f itted child restraints .
Child sa fety
- 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 compa rtment.
- Never use child restraint tether anchorages to secure safety be lts 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 you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PAS SENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
i n spe cted by your Audi dea ler.

Child safety
Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.
.,. Depress the spring catch on the hook and re­
leas e it from the anchorage.
(D Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently stretched around the tether strap . This applies especially to
leather seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc­
tions carefully to determine how to properly in­
stall the tether.
A WARNING
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, or
door.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and 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.

\.J ' 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 reco mm endati on
The fuel recommended for your vehicle is unlead­
ed pr em ium
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,
p lease 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 . Th is rating
may be spec ified 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 pe r­
formance.
U se unlea ded gas oline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European count ries . We recommend that
you do not ta ke your vehicle to areas or countries
where un leaded gasol ine may not be availab le.
For more information on refueling your vehicle,
see
~ page 193.
Octane r ating
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 poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
ings that can usually be found on the filler pump:
- Premium Grade: 91 -96 AKI
Ch eck ing and Filling
- Regu lar Grade: 87 -90 AK I
E xplanation of the abb reviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
(D Note
- Do not use any fue l w ith octane ratings low­
er than 8 7 AKI or 91 RON otherwise expen­
sive engine damage w ill occur .
- Do
not use 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 gas olin e con tainin g alcoh ol or MTBE
( meth yl t ert ia ry but yl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of gasolin e methanol (wood alcohol or
methyl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of g asoline and ethanol (grain alc oh ol or
e th yl alcoh ol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Bl end of g asoline and MTBE
-Anti-knock index must be 87 AK I or h igher.
- Blend must contain not mo re than 15% MTBE.
Se asonall y adjust ed ga soline
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 ..,.
191

Check ing and F illing
fi ll up at busy gas stations where the seasona l
adjustm ent is more likely to be mad e in time .
0 Note
-Me thanol f uels which do no t 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 spec i­
fied criteria in this chapter .
- If you are unable to determine whether or not a particular fuel blend meets the spec i­
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 fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion 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 b lends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . All gaso line grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l 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 TIE R Detergent Gas­
oline. For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website (www.toptiergas .com) .
192
After an extended period o f using inadequate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
([) Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the Audi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles wi th diese l en gin e
Always use ULSD (Ultra Low Sulfur Diese l) No. 2 .
The ULSD No. 2 meets the ASTM D97S.
D iesel fuel w ith concentrations of b iod iesel high­
er than 5 % such as B l 1, B20 or BlOO are st rict ly
prohibited .
Se rvice station fuel pumps are labe led wi th the
correc t fu el i nfo rmation for easy recogn ition by
the user . If the diesel fue l pump is not labe led
ask the station operator what fue l is being dis­
pensed before filling up your vehicle .
U LSD No . 2 may no t be ava ilable outside the USA
and Canada . Be s ure to check befo re t raveling to
other countries .
U LSD No . 2 can become th ic k e r i n very co ld tem­
peratures, and this can impa ir the e ng ine's s tart­
i ng and running . Depend ing on the season, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
so ley for use with ULSD No . 2 . Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amo unt of incorrect fuel in
the fuel tank, do not start the engine under
any c ircumstances. Immed iate ly contact the
nearest author ized A udi dealer or author-
ized Aud i Serv ice Facility fo r ass istance .

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 195 .
You can find the fuel tank capacity of your vehicle in
~ page 262 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For mo re in­
formation about fuel specifications , see
~ page 191 .
You r vehicle fuel tank has an onboa rd refuelling
vapor recovery sys tem . This fea tu re 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 norma l operating conditions, never car­
ry additiona l 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/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalyt ic
converter.

"' Then press on the left s ide of the tank door un-
til it latches.
Once the pump nozzle switches off, the fuel tank
is "full ". Do not fill the tank mo re . Otherwise the
expans ion space in the tank w ill be filled .
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. Fo r additional informa tion on fuel,
see
~ page 191.
193

Checking and Filling
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ~ page 262.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp~
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 no zzle
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
vehicle again while fueling, close the door
and touch metal to discharge static electric­ity 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:
- 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.
194
-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).
(D 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 .
(D Note
Applies to: vehicles with diesel eng ines
If the fuel tank runs completely empty, the
ignition must remain switched on for at least
30 seconds after refueling before starting the
engine. It may take longer than usual for the
engine to start, even up to a minute. This is
because the air must first bleed out of the
fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(y Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside.
(D Tips
Applies to: veh icles with diesel e ngin es
Diesel vehicles are equipped with a misfueling
guard
l) . It allows the vehicle to be fueled on-
ly with a diesel fuel pump nozzle . .,.

-A worn or damaged nozzle or a nozz le that
i s too sma ll may not be ab le to open the
diesel misfueling guard. If this is the case,
try turning the nozzle before insert ing it in
the fue l fi ller neck, use a different fuel
pump, o r see an a uth orized Audi dea ler or
aut horized Aud i Serv ice Fac ility fo r ass is­
tance.
- The m isfueling guard does not open when
adding fue l from a fue l conta iner . You ca n
bypass it by addi ng the diesel fuel s low ly.

Selective catalytic reduction (AdBlue/DEF)
General information
Appl ies to: vehicles with selective catalytic reduct io n
In vehicles with selective catalyt ic reduction, a
urea sol ution (AdBlue/DEF) is injected into the
exhaust system before a nitrogen oxide catalytic
converter to reduce nitrogen em issions . The urea
solution is known as Ad Blue or DEF (Diesel Ex­
haust F luid) . Ad Blue is used in the fo llow ing .
The Ad Blue is carried in a separate tank in the ve­
hicle . The AdBlue usage acco unts for app rox i­
mately 0 .5% to 2.5% of the diesel fuel that is
u sed .
When a message about refi lling the AdBlue ap­
pears in the instrument cluste r display, you must

Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is func tioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline c> page 191, Fuel
supply .
~ Never run the tank down all the way to empty.
~ Never put too much motor o il in your engine
c> page 204, Adding engine oil.
~ Never try to push- o r tow-start your vehicle .
The catalytic converter is an efficient "clean -up "
device built into the exhaust system of the veh i­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust g as befo re they are re­
l eased into the atmosphere.
The exclusive use of un leaded fuel is critically im­
po rtant fo r the life of the catalytic converte r and
prope r funct io ni ng of the engine.
_&. WARNING
The temperat ure of the exhaus t sys tem is
high, both when driv ing and a fter stopping
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- D o not p ark or operate the vehicle in ar eas
where the hot exhaust system may come in
contact with dry g rass, brush, fuel spi ll or
other mate rial which can ca use a fire.
- Do not apply additiona l undercoating or
rustp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic conve rter or
heat shields . D uring driving, the substance
used for unde rcoat ing could overheat and
cause a fire .
Cl) Note
-Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
