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

LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To p rovide a simp ler and mo re practicab le way to
attach the ch ild restraint on the vehicle seat,
Federal regulations require spec ia l lower ancho­
r ages in vehicles and devices on new ch ild re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tethe r ancho rages and the lower anchorages is
now generally called t he LATCH system for
" Lower Anchorages and Tethers for Children" . In
Canada, the terms
" top tet her" wi th "lower u ni­
versa l anchorages" (o r "lowe r universa l anchor­
age bars") a re used to des cribe the system .
In other co untries the term
"ISOFIX" is used to
desc ribe the lower anchorages .
Fo rward-facing chi ld restraints manufactured af­
ter September
1, 1999, are required by U.S . fed­
era l regulations to comply with new child head
movement performance req uir ements . These
new performance requ irements make a tether
necessary on most new ch ild sea ts.
Installing a ch ild restraint that requires a top
tether wi thout one can se riously impair the per­
fo rmance of the c hild rest raint and its ab ility to
pro tect the ch ild in a co ll ision. I nstalling a ch ild
r es trai nt th at r equi res a top te ther wi tho ut the
top tether may be a vio lation o f st ate law.

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.

Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle Limited Warranty.
