use the safety belt height adjustment to help
adjust the shoulder portion properly .
~ Secure unused safety belts on the rear seat
¢ page 139.
Children up to at least 8 years old (over 40 lbs. or
18 kg) are best protect ed in child safety s eats de­
signed for their age and weight. Experts say that
the skeletal structure, particularly the pelvis, of
these children is not fully developed, and they
must not use the vehicle safety belts without a
suitable child restra int .
It is usually best to put these children in appro­ priate booster seats . Be sure the booster seat
meets all applicable safety standards .
Booster se ats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass across
the child's body in the right places. The rout ing of
the belt over the child's body is very important
for the child's protection, whether or not a boos­
ter seat is used. Chi ld ren age 12 and unde r must
a lways ride in the rear seat .
Ch ildren who are at least 4 ft . 9 in. (57 inches/
1.45 mete rs) tall ca n genera lly use the veh icle's
three po int lap and shoulder be lts. Neve r use the
l ap belt po rtion of the vehicle 's safety belt alone
to restrain any child, regardless of how big the
chi ld is. A lways remember that children do not
hav e the pronounced pelvic structure required for
the proper function of lap belt port ion of the ve­
h icle 's three point lap and shoulder be lt s. The
chi ld 's safety absolutely requires that a lap belt
port ion of the safety belt be fastened snugly and
as low as possible around the pelvis . Never let
the lap belt portion of the safety belt pass over
the child's stomach or abdomen.
In a crash, a irbags must inflate within a blink of
an eye and wit h considerable force . In order to do
its job, the airbag needs room to inflate so that it
will be there to p rotect the occupant as the occu­
pant moves forward into the a irbag.
A vehicle occupant who is out of position and too
close to the airbag gets in the way of an inflating
ai rbag. When an occ upant is too close, he o r she
will be struck v iolently and will receive ser ious or
possibly even fatal injury.
Ch ild safety
In order for the a irbag to offer protection, it is
important that a ll vehicle occupants, especially
any ch ildren, who m ust be in the front seat be­
cause of exceptiona l circumstances, be properly
res tra ined and as far away from the airbag as
poss ible. By keeping room between the child 's
body and the front of the passenger compart­
ment, the a irbag can inflate completely and pro­
vide s upplementa l protec tion in certain frontal
collisions.
A WARNING
-
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos ­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
i njury and death in a collision or other emer­
gency situation. To help reduce the risk of se­ rious personal injury and/or death:
- The shou lder belt must lie as close to the
center of the ch ild's collar bone as possible
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck. The lap belt must lie ac ross the pelvis
and never across the stomach o r abdomen.
Make sure the bel t lies flat and sn ug. Pu ll on
the belt to tighten if necessary.
- Fail ure to properly route safety bel ts over a
child's body w ill cause severe injuries in an
accident or other emergency situation
¢ page 106.
- The rear side of the chi ld safety seat should
be positioned as close as possible to the
backrest on the vehicle seat. Adjust or re ­
move the rear seat head restraint if it is dif­
f icult to insta ll the ch ild seat with the head
restraint in place¢
page 44 . Install the
head restraint again immed iately once the
child seat is removed . Driving without head
rest raints or with head restra ints that a re
not properly adj usted increases the r is k of
serio us or fatal ne ck in jury dramatically .
- Never let a chi ld put the shoulder belt under
the arm or behind the ba ck, because i t could
cause severe inj uries in a crash .
- Ch ild ren on the fron t seat of any car, even
with Advanced Airbags, can be seriously in-
jured or even ki lled when an airbag inflates .

Child safety
-Never let a child stand or kneel on any seat,
for example the front seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in
any way during an accident can be struck by
a deploying airbag. This will result in serious
personal injury or death.
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the
PASSENGER AIR BAG
OFF
light must come on and stay on, when­
ever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, perform the
checks described
Q page 124, Monitoring
the Advanced Airbag System.
- Take the child restraint off the front passen­
ger 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.
-Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used

Q page 134, Important information.
Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
144
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size.
A WARNING
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision .
-
-Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always make sure that the rear seat back­
rest to which the center rear safety belt is
attached is securely latched whenever the
rear center safety belt is being used to se­
cure a child restraint.
-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 in­
flates.
- 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, 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 when­
ever using a child restrained in a vehicle is
being used¢
page 134. Special precautions
apply when installing a child safety seat on
the front passenger seat ¢
page 115, Child
restraints on the front seat- some impor­
tant things to know .
A WARNING
Always take special precaut ions if you must
install a forward or rearward-fac ing ch ild 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
PA SSENGER 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 124, Monitoring
the Advanced Airbag System.
- Take the ch ild restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
P AS SEN GER AIR
B AG OFF
light does not stay on whenever
the ignition is switched on .
- Improper installation of ch ild restraints can
reduce their effect iveness or even prevent
them from providing any protection .
- An improperly installed ch ild restraint can
interfere w ith the airbag as it deploys and
seriously injure or even kill the child .
- Always carefully follow the manufacturer's
instructions provided w ith 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 c rash.
A WARNING
Forward-fac ing child rest raints :
-
Child safety
-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 side airbag .
- 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 posit ion in the up and down ad­
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
ad justment range, as far away from the air­
bag as possible, before installing the for­
ward-facing ch ild restraint.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint 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 BAG
OFF
li ght comes on and stays on all the time
wheneve r the ignit ion is switched on .
_& WARNING
-Rearward-facing ch ild restraints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
serious ly 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 carr ier with great force and
will smash the child safety seat and child aga inst the backrest, center armrest, door
or roof .
- Always be especia lly careful if you must in­
stall a rearward facing child safety seat on
the front passenge r seat in except iona l cir­
cumstances.
- A t igh t tether strap on a rearwa rd-facing
child restraint attached to the front passen­
ge r seat can put too m uch p ressure on the
weight-m at 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 were on the
seat and deploy the Advanced A irbag when

~ 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

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 .

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.

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

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

- 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
