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. .,..

Child safety
_& 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 vehicle.
- Never install a child restraint without a properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used .
- Improper use of child restraint LATCH lower
anchorage points can lead to injury in a colli­
sion. The LATCH lower anchorage points are
designed to withstand only those loads im­
posed by correctly fitted child restraints .
- Never mount two child restraint systems on
one LATCH lower anchorage point .
- Never secure or attach any luggage or other
item to the LATCH lower anchorages .
(D Tips
-In Canada, the terms "top tether" with
"lower universal anchorages" (or "lower uni­
versal anchorage bars") are used to describe
the system.
- In other countries, the term "ISO FIX" is
used to describe the lower anchorages.

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.

.
- 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 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
seating position and have the airbag system
inspected by your Audi dealer.

Checking and Fill in g
These fuels contain substances that can se ­
verely damage the fuel system and the en­
gine if the engine is started .
- If the diesel f uel quality is poor, it may be
necessary to have the water d rained from
the water separator in the
fuel filter more
often than specified in the maintenance
schedule. This can help reduce engine ma l­
funct ions

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side pane l behind the fuel f iller flap.
If the power locking sys tem should fail, you can
still open the flap manua lly -for detai led instruc ­
tions see

You can find the fue l tank capacity of you r vehicle
in
c:> page 260.
The label on the inside of the fue l filler flap te lls
you t he cor rect fuel for your vehicle. For more in­
form ation abo ut fue l specifications, see
c:> page 190 .
Your vehicle fuel tank has an on board refue lling
vapor re cove ry system . This feature helps to p re­
ve nt fuel vapors from escaping from the tank and
pollut ing t he environment w hile you refue l yo ur
ve hicle. In orde r to fill the tank p roperly whi le
protecting the environment, please follow this
refueling procedure carefully.
A WARNING
Under normal operating conditions, never ca r­
ry additional fuel containers in your car . Gas
canisters and ot her conta iners used to trans­
port fuel can be dangerous . Such contai ners,
full or empty, may leak and could cause a fire
in a collision. If yo u m ust t ransport fue l to
use fo r yo ur l awn m owe r, snow b lower, etc.,
be very ca re ful and a lways observe loca l and
state laws rega rding the use, transportation
and sto rage of such fuel containe rs . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 - 86).

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious burns and other injuries.
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and start a fire.
- Do no t use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling . If
you must make an exception and enter your
vehicle again while fueling , close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident .
-If you must make an exception and trans­
port a fuel container, note the following:
Checking and Filling
- Never fill the fuel container with fuel
while it is in or on the vehicle . Static elec­
tricity is discharged when filling which can cause the fuel vapors to ignite and increas­
es the risk of an explosion .
- Always place a fuel container on the
ground before filling .
- Always hold the fuel nozzle completely in
the fuel container when filling .
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This prevents static electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug ­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death.
- Follow legal requirements when using,
storing and transporting fuel containers .
- Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
Q) Note
-Remove spilled fuel from vehicle paint im­
mediately , because it can damage paint .
- Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires .
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
- If the fuel tank runs completely empty in a
vehicle with a
diesel engine, the ignition
must remain switched on for at least 30
seconds after refueling before starting the
engine. It may take longer than usual for
the engine to start, even up to a minute.
This is because the air must first bleed out of the fuel system when starting the engine .
@ For the sake of the environment
- If
the fuel nozzle is used correctly, it will in­
dicate that the tank is full the first time it
switches off automatically. Do not try to add
more fuel, because it can spill over. Also, "'

The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fue l spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
f uel will a lready se riously degrade the
performance of the c ata lytic conver ter.
- Do not exceed the co rrect engine oil leve l
9page203.
-Do not d rive until the fuel tank becomes
complete ly empty. The eng ine could misfi re.
U nburned f uel co uld also ge t in to the e x­
haust system and this could ca use the cata ­
l ytic converter to overheat.
- Do no t sw itch off the ignition wh ile the vehi­
cle is moving.
- Do not con tinue to oper ate yo ur vehicle un­
der these cond itions, as o therwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.

Control System:
Checking and Fillin g
- Have your vehicle maintained properly and
in accordance with the serv ice recommen­
dat ions in yo ur Warranty
& Maintenance
booklet.
- Lack of prope r maintenance as we ll as im­
p roper use of the vehicle will impair the
f u nction of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exha ust gas can have a
su lfur-like exhaust gas sme ll under some op­
erating states. Th is depends on the s ulfur
