Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially chi ldren:
~ A lways use the right chi ld safety seat for each
c h ild and a lways use it properly
¢ page 172.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe ­
ty seat .
~ When using the vehicle safety be lt to insta ll a
c hi ld safety seat , you must first activate the
conve rtible locking retractor on the safety be lt
to prevent the child safety seat from mov ing
¢ page 177 .
~ Push the child safety seat down wit h your fu ll
weight to get the safety be lt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
~ Secure unused safety belts on the rear seat
¢ page 172 .
Always remember: Even though your vehicle is
equ ipped w ith an Advanced Airbag system, all
children, especially those 12 years and younger,
should always r ide in the back seat prope rly re­
stra ined fo r th eir age and size.
_& WARNING
N ot using a c hild safety seat, usi ng the w rong
c hild safety seat or imp roper ly installing a
170
chi ld restraint increases t he risk of serious
personal injury and death.
- All vehicle occ upants and especially children
must be restra ined properly whenever rid ing
in a vehicle. An unrestrained or improperly
restrained child cou ld be injured by strik ing
the inter ior or by being ejected from the ve­
h icle dur ing a sudden maneuve r o r i mpact.
An unrest rained or imprope rly rest rai ned
child is a lso at g rea ter r is k of inj ury o r death
through con ta ct w it h an infl ati ng a irbag.
- Commerc ia lly availab le child safety seats
a re requ ired to comply with U.S. Federal
Motor Vehicle S afety Standard ( FMVSS) 2 13
(in Canada CMVSS 213).
- When buying a child restra int, select one
that fits your chi ld and the vehicle .
- Only use child restra int systems that fully
contact the flat port ion of the seat cush­
i o n. The ch ild restraint must not tip or
lean to e ither side . Audi does not recom­
mend using child safety seats that rest on
l egs or tube -like frames. They do not p ro­
v ide adequate cont act wi th t he seat.
- Always heed all lega l req uirements per­
ta in ing to the inst allation and use of child
sa fe ty seats and caref ully follow the in ­
str uctions provided by the manufact urer
of the seat you are using .
- Never a llow children under 5 7 inc hes
( 1. 45 meters) to wear a normal safety be lt.
They must a lways be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to t he abdomen and
neck areas dur ing sudden brak ing maneu­
vers or accidents .
- Never let more than one c hild occupy a chi ld
safety seat.
- Never let babies or o lder ch ildren ride in a
ve hicle w hile sitting on the lap of a nother
passenger.
- Holding a c hild in your a rms is never a s ub­
stitute fo r a ch ild restraint system .
- The s tronges t person cou ld no t hold the
c hil d with the forces tha t exist in an acc i­
dent. The c hild will strike the inte rior of
the ve hicle and can also be struck by the
passenger.

Child safety
-Take the child restraint off the front passen­ger seat and install it properly at one of the

A WARNING
A child in a child safety seat installed with the
LATCH lower anchorages or with the standard
safety belt or a child in a booster seat on the
rear seat could play with unused rear seat
safety belts and become entangled. This
could cause the child serious personal injury
and even death.
-Always secure unused rear seat safety belts out of reach of children in child seats such
as by properly routing them around the
172
head restraint of the seat where the child
restraint is installed .
- Never activate the convertible locking re­
tractor when routing the safety belts around
the head restraints.
-Never let anyone sit at the center rear seat­
ing position if the center rear safety belt has
been routed around a rear head restrain t.
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs . or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.

Infants up to about one year (20 lbs. or 9 kg) are
best protected in special infant carriers and child
safety seats designed for their age group. Many
experts believe that infants and small children
should ride only in special restraints in which the
child faces the back of the vehicle. These infant

Child safety
Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs . and 80
lbs. (18 kg and 36 kg) who are less than 4
ft. 9
in. (57 inches/1.45 meters) tall .
Fig. 165 Rear seat: child properly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these chi ldren up so
that the safety belt will pass properly
over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
.. Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat .
.. The shoulder belt must lie as close to the cen­
ter of the child'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 across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and snug. Pull on the belt to tight­
en if necessary .
.. If you must transport an older child in a boos­
ter seat on the front passenger seat, you can use the safety belt height adjustment to help
adjust the shoulder portion properly .
.. Secure unused safety belts on the rear seat
c>page 172.
Children up to at least 8 years old (over 40 lbs or
18 kg) are best protected in child safety seats 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
176
must not use the vehicle safety belts without a
suitable child restraint .
It is usually best to put these children in appro­
priate booster seats. Be sure the booster seat
meets all applicable safety standards.
Booster seats 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 routing of
the be lt over the child's body is
very important
for the child's protection, whether or not a boos­
ter seat is used. Children age 12 and under must
always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 inches/
1.45 meters) tall can generally use the vehicle 's
three point lap and shoulder belts. Never use the
lap belt portion of the vehicle's safety belt alone
to restrain any child, regardless of how big the
c hi ld is. Always remember that children do not
have the pronounced pelvic structure required for
the proper function of lap belt portion of the
ve­
hicle's three point lap and shoulder belts. The
child's safety absolutely requires that a lap belt
portion 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, airbags must inflate within a blink of
an eye and with considerable force. In order to do its job, the airbag needs room to inflate so that it
will be there to protect the occupant as the occu­ pant
moves forward into the airbag .
A vehicle occupant who is out of position and too close to the airbag gets in the way of an inflating
airbag. When an occupant is too close, he or she
will be struck violently and will receive serious or possibly even fatal injury .
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of exceptional circumstances, be properly
restrained and as far away from the a irbag as
possible. By keeping room between the child's

A WARNING
Not using a booster seat, us ing the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of ser ious personal
inju ry and death in a co llision or ot her eme r­
ge ncy sit uat io n. To help red uce the r isk of se­
r ious persona l injury and/o r death:
- T he shoulder be lt must lie as close to the
cen ter o f the child's collar bone as poss ib le
and must lie flat and snug on the uppe r
body. It must never lie across the throat or
neck . The lap be lt must lie across t he pe lvis
and never across the stomac h or abdomen.
Make sure that the belt lies flat and s nug.
Pull on the belt to tighten if necessary .
- Failure to proper ly route safety belts over a
child's body will cause severe injuries in an
acc ident or other emergency s ituation
¢ page 134.
- The rear side of the child safety seat should
be pos it ioned as close as poss ible to the
back rest on the vehicle seat.
- For adjustable head restraints : adj ust or re­
move the rear seat head restraint if it is d if­
ficult to i nstall the child seat w ith the head
restra int i n place
¢page 49. Install the
head restrain t again immedia tely o nce the
child seat is remove d. Driving w ithout head
restraints or with head restraints that are
not properly adjusted increases the risk of
serious or fata l neck injury dramatically.
- Never let a child put the sho ulder be lt under
the a rm or be hind the bac k, because it co uld
cause seve re injur ies in a crash.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an a irbag inflates.
- Never let a child stand or knee l on any seat,
for example the front seat.
- Never let a child ride in the cargo area of

Gasoline grade
A pplies to: ve hicles with gasoline 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 with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .topt iergas.com).
The individual gasoline grades are differentiated
by
octane ratings. T his value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel fi ller door.
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regu lar gasoline with minimum 87 AKI/
91 RON
i::> (@ .
The maximum engine power is only reached if
premium gasoline 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gasoline with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regular gasoline 87 AKI/ 91 RON . However
this does reduce the engine power slightly.
({D) Note
-Fill in g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deterioration to the catalytic
converter function.
- When gasoline with an octane rating that is
too low is used, high speeds or heavy engine
load can lead to eng ine damage.
Checking and Filling
(D Tips
The vehicle may be filled with fuel that has a
higher octane rating than what is required by
the engine .
Blended gasoline
Applies to : vehicles wi th gasoli ne e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
coho l or MTBE (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 AKI or higher.
- Blend must not contain 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
fill up at busy gas stat ions where the seasonal
adjustment is more likely to be made in time .
@ Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plast ic and rubbe r components in the
fuel system.
- Do not u se fuels that fail to meet the speci-
fied criteria in this chapter.
.,.

Checking and Filling
-If you a re 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 a re 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 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 engin e
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 TI ER Dete rgent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.

- If you must transport fuel in a fue l contain ­
er, please note the following:
Ch eck ing and F illing
- Always place a fue l container on the
ground before filling . Never fill the fue l
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
wh ile refueling and the fuel vapors could
i gnite .
- For fuel containers made of metal, the fuel p ump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,
stor ing and t ransporti ng f uel conta iners.
- Make su re that the fuel containe r meets
t h e in dust ry standa rds, for example ANS I
o r ASTM F8S2 -86.
@ Note
- Remove fuel that has overflowed onto any
veh icle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel
tank is completely
empty. The irregula r supply of fue l that re­
sults from that can cause eng ine misfi res.
U nc ombus ted fuel will ente r th e exhaus t
system and increase the risk of damage to
the cata lytic converter.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise f uel

([) Note
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­ store the correct mixture ratio with the
spec ified coolant additive as soon as possi­
ble.
- Only refill with new coo lant.
- Radiator sealant must not be mixed w ith
the coo lant .
Adding coolant

cover
Observe the safety precautions~ page 189,
Working in the engine compartment .
Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank~ page 192, fig . 179. The coolant level
must be between the MIN and MAX markings
196
when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k
~CD -
• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 195 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.
