Installing a child restraint with LATCH
lower anchorages
Whenever you install a child restraint always fol­
low the child restraint manufacturer's instruc ­
tions.
Fig. 128 Lower anchorages: proper mount ing
Mounting
.,. Make sure the seatback of the rear seat bench
is in the upright position and securely latched
in place.
.,. Attach both hook-on connectors with the spring
catch release on the child safety seat onto the
LATCH lower anchorage so that the connectors
lock into place
¢ fig. 128 .
.,. Pull on the connector attachments to make
sure they are properly attached to the LA TC H
lower anchorage .
.,. Pull straps tight fo llowing the child restraint
manufacturer's instructions.
R ele asing
.,. Loosen the tension on the straps following the
child restraint manufacturer's instructions.
.,. Depress the spring catches to release the an­
chorage hooks from the lower anchorages .
Remember: Use tether straps to he lp keep the
child restraint firmly in place.
A WARNING
Improper use of the LATCH system can in­
crease the risk of serious personal injury and
death in an accident.
- These anchors were deve loped only for child
safety seats using the "LATCH" system.
- Never attach other child safety seats, belts
or other objects to these anchors.
Ch ild sa fety
- Always make sure that you hear a click when
latching the seat in place . If yo u do not hear
a cl ick the seat is not secure and could fly
forward and hit the inter ior of the vehicle,
or be ejected from the veh icle.
A WARNING
-Improper installation of child restra ints w ill
i ncrease the risk of injury in an accident.
-Always follow the ch ild restraint system
manufacturer's instructions for proper in­
stallat ion of the chi ld restraint system a nd
p roper use of tether straps as well as the
lowe r ancho rages or safety belts in yo ur
ve­
hicle.
- Always read and heed the important info r­
mat ion and WARN INGS abou t ch ild safety
a nd the installat ion of child restraint sys ­
tems¢

Tether anchors and tether straps
Fig. 129 Tether ancho rs: attac hmen t hook locatio ns be ­
hind the rear sea tbacks
The tether anchors for the rear seating positions
are located on the backside of the rear seatbacks
¢ fig . 129 .
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 veh icle.
T he purpose of the tether is to reduce the for ­
ward movement of the chi ld restraint in a crash,
in order to help reduce the risk of head injury
that could be caused by striking the vehicle inte-
rior.
liJ,

Child safety
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 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
caus ing 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
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
150
seating position and have the airbag system
inspected by your Audi dealer.
Installing the upper tether strap on the
anchorage
Fig. 130 Tether strap: proper routing and mounting
Fig. 131 Tether strap: proper rout ing and mount ing
Installing the tether strap
.,. Release or deploy the tether strap on the child
restraint according to the chi ld restraint manu­
facturer's instructions.
.,. Guide the upper tether strap
under the rear
head restraint and into the rear cargo area
r:::;, fig. 131 (raise the head restraint if necessa­
ry). For child restraints with V-tether straps, al­
ways make sure that the head restraint guide
rods do not interfere with any part of the top
tether strap.
.,. Slide the tether strap hook over the anchor
bracket.
.,. Pull on the tether strap hook so that the spring
catch of the hook engages .
.,. Tighten the tether strap f irmly following the
child restraint manufacturer's instructions.
Releasing the tether strap
.,. Loosen the tension following the child restraint
manufacturer's instructions.

~ Depress the spring catch on the hook and re­
lease it from the anchorage.
@ Note
If you leave the ch ild 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
Current ly, few rear-facing chi ld 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 w ill be
ser iously injured and can be killed if the front
airbag inflates -even w ith an Advanced Ai rbag
System.
- T he 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.
- A tight tether or other strap on a rearward­
f acing 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 Sys­
tem. The heav ier weight registered can
make the system work as though an adult
were on the seat and deploy the Advanced
Airbag when it must be supp ressed causing
serious or even fatal injury to the child.
-If you must install a rearward facing ch ild
safety seat on the front passenger seat be­
caus e of exceptiona l circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
Child safety
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected by your Audi dealer.

Checking and Filling
Fuel
Gasoline grade
A pp lies to: ve hicles w ith gaso li ne engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llow ing headings match the co rrespon ding
sticker in the fue l fi ller door .

Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
Yo u may use unleaded gasoline b lended wi th al­
cohol o r MTBE (commonly referred to as oxygen ­
ates) if the blended mixt ure meets the fo llowing
criteria :
Blend of ga soline methanol (wood alcohol or
meth yl alcohol)
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more tha n 2% co -solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Anti -knock index must be 87 AK I or higher .
- Blend must not co ntai n mo re t han
15% etha-
nol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades a re blended to pe rform es­
pec ially well for w in ter o r su mme r dr iv ing . D ur ­
i ng seasonal change-ove r, we s ugges t th at yo u
fill up at busy gas stat ions where the seasona l
adjustment is more likely to be made in time.
(D Note
- Meth ano l fuels which do not meet these re­
q uirements may cause corrosion and dam ­
age to plastic and rubber com ponents in the
fuel system.
- Do not use fue ls that fa il to meet the speci­
fied cr iteria in th is chapter .
-If you are una ble to dete rm ine whether or
not a part icu lar f uel blend meets the speci ­
fications, ask yo ur service station or its fue l
supplier.
- Do not use fue l for which the contents can­
not be ident ified .

-Fuel system damage and performance prob­
l ems 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 majo r concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades d iffer 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, built-up carbon deposits can rob your en­ gine of peak performance.

quality is not covered by the Audi New Vehi ­
cle Limited Warranty.

turn on.
If the central loc king system malf unc tions, the
f u e l filler door may emergency release
¢ page 155.
A WARNING
An improper fue ling procedure and improper
hand ling of fue l can lead to explosions, f ires,
severe bu rns and other injur ies.
- Do not smoke and keep away from open
flames.
- The ignition must be switched off when re­
fueling .
- Cell phones, radio devices and other radio
equipment should always be switched
off
when refueling. Electromagnet ic rays cou ld
cause sparks and start a fire.
- If you do not insert t he fue l pump nozzle a ll
the way into the filler tube, then f ue l can
leak out. Spilled fuel can ignite and start a
fire .
- Never get into the vehicle when refueling. If
there is an exceptional situation where t he
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle agai n. This will reduce the
r isk of e lectros tat ic discharge t hat can ca use
flying spar ks. Sparks can start a fire when
ref ue ling.
A WARNING
We recommend that you do not t ransport any
fuel containers in the vehicle . Fuel could leak
out of t he container and ignite, especially dur-
l) Market -s pecific
154 ing an accident. Th
is can ca use explos ions,
f ires and injuries.
- If you must transport fuel in a fue l contain­
er, p lease note the following:
- Always place a fue l co nta iner on the
ground befo re fil ling . Neve r fill the fuel
contai ne r with fuel whi le i t is in o r o n the
vehicle. Elect rostatic charge can oc cu r
while refueling and the fuel vapo rs could
ignite.
- Fo r fuel con tai ners made o f me tal, the
fuel p ump nozzle must a lways maintai n
contact with the container to reduce the
risk of stat ic charge.
- Insert the fuel pump nozz le as far as pos­
sible into the f iller opening wh ile refuel­
ing .
- Fo llow lega l req uirements when using,
stor ing and transporting fuel conta iners .
- Make su re t hat the fuel container meets
the i nd ustry standards, for example ANSI
or ASTM F852-86.
(D Note
- Remove fue l tha t has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel tan k is com plete ly
empty . The i rreg ular s upply of fue l that re­
sults from that can cause eng ine misfires .
Uncombusted fuel will ente r the exhaust
system and increase the risk of damage to
the catalytic converter .

Checking and Filling
-Never open the cap on the coolant expan­
sion tank when the engine is warm. The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any circumstances. This increases the risk of
burns.
- If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so
that clothing, jewelry or long hair do not
156
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine .
- Limit your exposure to exhaust and chemi­ cals to as short a time as possible
