justed.
Because airbags inflate in the blink of a n eye w ith
great for ce, things you have on you r lap or have
p laced on the seat cou ld become dangerous pro ­
jectiles, and be pushed into you if the airbag in ­
flates.
When an a irbag deploys, fine dust is released .
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irr itate skin.
It is important to remember that while the sup­
p lemental airbag system is designed to reduce
the likelihood of ser ious injuries, other inj uries,
for example swell ing, bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body . Front airbags only supplement the
three po int safety belts i n some fronta l co llisions
i n which the veh icle decelerat ion is high enough
to deploy the airbags.
F ront airbags will not deploy:
- if the ignit ion is switched off when a crash oc -
curs,
- in s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh­
o ld needed for airbag deployment as registered
by the electronic contro l unit .
Th e front passeng er airbag will a lso not
deplo y:
- when the front passenger seat is not occupied,
- when the weight on the front passenger seat as
sensed by the Advanced Airbag System indi­
cates that the front airbag on the passenger
s ide has to be turned off by the electronic con­
trol unit (the
P A SSENGER AIR B AG OFF light
comes on and stays on).
A WARNING
Sitting in the wrong pos ition can increase the
r isk of se rious injury in c rashes .
Airb ag sys tem
-To reduce the risk of injury when the ai rbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be seriously in jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye
Q page 139.
A WARNING
A child in a rearward-facing child safety seat
i nsta lled on the front passenger seat will be
seriously injured and can be k illed if the front
a irbag inflates - even with an Advanced Airbag
System .
- The inflating airbag will hit the child safety seat or infant ca rrier with great force and
will smash the child safety seat and child aga inst the backrest, center armrest, door
or roof.
- Always install rear-fac ing child safety seats
on the rear seat.
- If you must install a rea rwa rd facing child
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PA SS ENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your au thori zed A udi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be ­
ing p ushed into you as the airbag inflates .
- Never hold things in yo ur hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area o f
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.

Child safety
-When buying a child restraint, select one
that fits your child and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames . They do not pro­
vide adequate contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety belt.
They must always be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents.
- Never let more than one child occupy a child
safety seat.
- Never let babies or older children ride in a
vehicle while sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rearward-facing child safety
seats or infant carriers on the front passen­
ger seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates -even with an Advanced Airbag Sys­
tem .
- The inflating airbag will hit the child safe­
ty seat or infant carrier with great force
and will smash the child safety seat and
child against the backrest, center arm
rest, door or roof.
- Always install rearward-facing child safety
seats or infant carriers on the rear seat.
162
-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 into
the rearmost position of the passenger
seat's fore and aft adjustment range, and
as far away from the airbag as possible be­
fore installing the child restraint.
- 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.
- 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 read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used¢

Ch ild safety
Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint .
Always heed the ch ild safety seat manufactu rer 's
ins truct ions when installing a child restraint in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, prefer ably
on the rear seat .
.. Slowly pull the belt

.. Route it around or through the child restra int
be lt path
¢ & .
.. Push the ch ild safety sea t down with you r full
weigh t to ge t the safety belt really tight.
.. Insert the belt tong ue into the b uck le for that
seating position .
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat .
.. You should hear a ''cl icking" noise as the belt
w inds back into the inertia reel. Test the con ­
vert ib le lock ing retractor by pull ing on the belt .
You shou ld no longer be able to pull the belt
out of the re tractor. The convertib le loc kin g re­
t ractor is now activated.
.. Make sure that the red release button is facing
away from the c hild restraint so that it can be
unbuckled quickly .
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
A WARNING
Using the wrong ch ild rest raint o r an improp­

Driving and th e en vironm ent
(D Tips
- Check the depth of the water before driving
through it .
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your veh icle to drive
through safely.
- Avoid driving through salt water because it
can cause corrosion .
Catalytic converter
It is very impor tant tha t your emission con trol
system (ca talytic converter) is functioning prop ­
erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline ¢ page 198,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 20 7, 9::?l Adding engine oil .
~ Never try to push- or tow-start you r vehicle.
The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of the vehi­
cle. The cata lytic conve rter 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 critica lly im­
portant for the life of the catalytic conve rter and
p roper 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 exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park or ope rate t he vehicle in areas
where t he hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
186
fold, exha ust pipes, cata lytic conve rter or
heat shields . D uring driving, the substance
used for undercoat ing could overheat and
cause a f ire .
Cl) Note
-Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 207.
-Do not drive until the fue l tank becomes
completely empty . The engine could mis­
fire. Unbu rned fue l cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not turn off the ign ition while the vehicle
is moving .
- Do not continue to operate your vehicle un­
der these conditions, as otherw ise fuel can
reac h the catalytic converter . T hi s could re ­
sult in overheat ing of the converter, requir­
ing its replacement.
- T o ass ure eff icient ope rat ion of the Emis­
sion Contro l System:
- Have you r vehicle maintained properly and
i n accordance wit h the service recommen­
dations in your Warranty & Ma intenance
booklet.
- Lack of proper ma intenance as well as im­
p roper use of the veh icle will impa ir 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, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. Th is depends on the sulfur
con tent of the fuel being used . Us ing a d iffer­
ent brand of fuel may help , or fi lli ng the tank
wi th lead-free super g rade g asoline.
