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 safe­
ty seat. An unlocked safety belt retractor
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 inflates.
- 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

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
T o provide a simpler and more practicable way to
attach the ch ild restra int on the veh icle seat, Fed ­
eral regulations require special lower anchorages
in vehicles a nd devices on new child restraints to
attach to the vehicle anchorages .
The combination of the tether anchorages and
the lower anchorages is now generally ca lled the
LATCH system f or " Lower Anchorages and
T ethers for Child ren ."
Forward -facing chi ld restraints manufactured af ­
ter September 1, 1999, are requ ired by U.S. fed­
eral regulations to comp ly w ith new ch ild head
movement performance requ irements . These
new pe rformance requ irements make a te ther
necessary on most new ch ild seats .
Installing a ch ild restra int that requires a top
tethe r without one can seriously impair the per­
fo rmance of the child restra int and its ability to
protect the ch ild in a co llision . Installing a ch ild
r est rain t that requ ires a top te ther w it h out t he
top tether m ay be a vio lation o f st ate l aw .
Child rest raint manufacturers offer LA T CH lower
anchorages on the ir chil d seats with hook-o n or
push-on connec tors attached to adjustab le
str aps.
In add ition to the LATCH lower anchorages, these
c hi ld restra int systems usually requ ire the use of
te the r straps to he lp keep the c hild restra int
firmly in pla ce. .,..

Tether anchors and tether straps
Fig. 147 Tether anchors: recess flaps behind the rear seat­
ba cks
The tether anchors for the rear seating positions
are located in recesses in the rear window shelf
~fig. 147
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 reduce the for­ ward movement of the child restraint in a crash,
in order to help reduce the risk of head injury that
could be caused by striking the vehicle interior.
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.
&_ 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.

Checking and Filling
Gasoline
Fuel supply
App lies to veh icles: w ith gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel re co mm en da tion
The fuel recommended for your vehicle is unl ead­
e d prem ium
grade gaso line. 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,
please 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 ins ide of the fuel filler flap . This rating
may be specified as AKI or RON .
Your vehicle may also be operated using unlead­
ed regular gasol ine with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/
91 RON octane fue l wi ll sli ght ly reduce engine
pe rformance.
U se un leade d ga solin e only . Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not ta ke you r vehicle to areas or countr ies
where unleaded gasoline may no t be ava ilable.
For more informat ion on refueling your veh icle,
see
¢page 192.
Octan e rat ing
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation . Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Prem ium Grade : 91 - 96 AKI
190
- Regular Grade: 87 -90 AKI
Explanation of the abb reviations:
AKI = Anti Knock Index = (R +M)/2 = (RON+MON)/
2
RON= Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use any fue l w ith o ctane rat ings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage w ill occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your veh i­
cle's catalytic converter and its abi lity to
control exha ust em issions.
Blended gasoline
App lies to vehicles: wit h gaso line e ngi ne
U se of g aso lin e cont aining alcohol or MTBE
( meth yl tert iary butyl ethe r)
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen­
ates) if the ble nded mixture meets the following
criteria:
Blend of gasoline methano l (wood alcohol or
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
