Child safety
-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 .
- Make sure there is enough space in front of
the child in the child seat . If necessary, ad­
just the angle and position of the seat in
front of the child seat.
- Forward -facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause serious injury to the child . Always install for­
ward-facing child safety seats on the rear
seat.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and well-being require that the following
special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a pas­ senger front and side airbag .
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier .
- Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint .
- Always make sure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child re­
straint so that the safety belt will be prop­
erly positioned .
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range .
- Always make sure that the backrest is in
the upright position .

The vehicle's safety belts a lone w ill not fit most
ch ild ren until they are at leas t 4 ft. 9 in. (57 in­
ches/1.45 meters) tall and weigh about 80 lbs. (36 kg) . Booste r seats raise these ch ildren up so
that the sa fety belt will pass p roper ly over the
stronger parts of their bodies and the safety be lt
can help protect them in a crash.
.,. Do not use the convertib le locking re trac tor
when using the veh icle's safety be lt 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 m ust lie across the pelvis and never
across the stomach or abdomen . Make sure the
belt lies flat and sn ug. Pu ll on the be lt to tight­

Children up to at least 8 years o ld (over 40 lbs or
18 kg) a re best protected in child safety seats de­
signed for their age and weight . Experts say that
the skeletal structure, part icu larly the pelvis, of
these ch ildren is not fully developed, and they
must not use the vehicle safety belts without a
su itable child restraint.

-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).
(D 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.
@) For the sake of the environment
If the fuel nozzle is used correctly, it will ind i­
cate that the tank is full the first time it
sw itches off automatically. Do not try to add
more fuel, because it can spill over. Also, the
expansion space in the tank will fill, which can
result in fuel spilling out when it becomes
warm and polluting the environment.
@ Tips
Fuel can age and may lead to problems when
starting . Audi recommends replacing the fuel
in your vehicle within six months.
@ Tips
- If the engine is running while fueling, va­
pors can escape or the fuel can spill over.
Because of th is, the fuel nozzle switches off
before the tank is full.
- Do not fue l the vehicle when the ignition is
switched on . Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
Checking and Filling
-The fuel filler door on your vehicle does not
lock when you lock the vehicle from the in­
side.
Fuel filler door emergency release
If the central locking system is faulty, the fuel
filler door can be unlocked manually.
Fig. 158 Rear of the vehicle: right rea r seat fo lded fo rward
The emergency release is located behind the
right rear seat.
The pull cable for the emergency release is locat­ ed on the cover .
.. Remove the cover from the trim .
.. Pull on the cover carefully
c:> fig. 158. The tab
on the cover must point forward in the direc­
tion you are pulling when pulling on the cover .
"' To open the fuel filler door, press on the left
side
c:> page 186, fig . 156 .
(D Note
Only pu ll on the cover until you feel resist­
ance. You will not hear it release. Otherwise
you could damage the emergency re lease
mechanism.
Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
.. Always use lead-free gasoline c:> page 184, Gas­
oline grade .
.. Never run the tank down all the way to empty. ~

Checking and Filling
"'Never put too much motor oil in your engine
¢ page 193 , Checking the engin e oil lev el and
adding oil.
"'Never try to push- or tow-star t your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the v ehi­
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 fuel 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 , fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 193.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can reach the catalytic converter. This could re-
188
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function 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 exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.
