seat will stay in place.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children , especially those 12 years and young­
er, should always ride in the back seat proper­
ly restrained 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
safety seat. An unlocked safety belt re­
tractor 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
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
- If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.

154 Child Safety
A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
w ith a passenger front and side airbag.
- Never put the forward-facing child re­
straint up, against or
very near the in­
strument panel.
-Always
move the passenger seat into its
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 . The
backrest must be adjusted to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched on.
A WARNING
Rearward-facing child restraints:
-A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates -
even
with an Advanced Airbag System.
- 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 be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System . The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­
ploy the Advanced Airbag when it must be suppressed causing serious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your Audi
dealer.
Activating the convertible locking
retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle . To activate the conver­
tible Lacking retractor:
.,. Place the child restraint on a seat , prefera­
bly on the rear seat.
.,. Slowly pull the belt
all the way out.
.,. Route it around or through the child re­
straint belt path
~ _&..
.,. Push the child safety seat down with your
full weight to get the safety belt really tight.
.,. Insert the belt tongue into the buckle for
that seating position .
.,. Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat.
.,. You should hear a "clicking " noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
vertible locking retractor is now activat ed.
.,. Make sure that the red release button is fac­
ing away from the child restraint so th at i t
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). .,.

170 Driving and en vironm ent
Driving through water on roads
Note the following to avoid vehicle damage
when dr iv ing t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
After d riving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads. Dry
the brakes f irst by bra king carefully to re ­
store the full braking effect .
({D Note
Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be severely damaged by driving
through wate r.
(D Tips
-Che ck the depth of the water before dr iv­
i ng through it.
- Do no t stop the veh icle, dr ive in reverse
or switch the engine off when d riving
th rough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the wate r
l evel and make it too deep for yo ur vehi­
cle to drive th rough safely .
- Avoid driving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
-
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
"' Always use lead-free gasoline¢ page 189,
Fuel supply.
"' Never run the tank down a ll the way to
empty .
"' Never put too much motor oil in your en­
gine ¢
page 200, ~ Adding engine oil .
"' Never try to push -or tow-start you r vehicle .
T he ca talytic converter is an efficient "clean­
u p" dev ice bui lt into the exhaust system of
the vehicle . The cata lytic conve rter bu rns
many of the pollutants in the ex ha u st gas be ­
fore they are re leased into the atmosphere.
T he exclusive use of unleaded f uel is c rit ically
important for the life o f the catalyt ic convert ­
er and prope r function ing of the engine .
A WARNING
-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 wh ich can
cause a fire .
- Do not app ly additional undercoating or
rustp roofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driv ing, the
substance used fo r under coating could
overhe at and cause a fire.
((0 Note
-Be aware that just one tank filling with
leaded fuel w ill alr eady ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed t he cor rect engine oil level
¢page 200.
-Do not dr ive until t he fuel tank becomes
completely empty. The engine cou ld mis­
fire. Unburned fuel could also get in to
the exhaust system and th is co uld cause
t he catalytic converter to overheat .
- Do not tu rn off the igni tion while the ve­
hicle is mov ing.
- Do not continue to ope rate your veh icle
under these conditions, as ot herwise fuel
can reach the catalytic converter. This
cou ld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assu re efficient operation of the Emis -
sion Control System : ..,.

CD Note
You should remove debris (such as insects)
from the headlight lenses on a regular ba­sis, for example when refueling your vehi­
cle. Never clean the headlights with a dry
cloth or sponge . Use a wet cloth or
sponge.
It is best to use soapy water .
Automatic car wash
The vehicle can be washed in almos t any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash . However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filtering of the wash
water , the type of wash and care material , etc .
If the paint has a dull appearance after going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and panoramic sliding sunroof*. Re­ move antenna if applicable.
If you have installed additional accessories on
the vehicle -such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed.

names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang ing th e engin e oil
The engine oil and oi l filter must be changed
according to the m ileage (kilomete rs) and
time inte rva ls specified in yo ur vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive eng ine repairs.
Changing the o il at the recommended inter ­
va ls is so very important because the lubricat ­
ing properties of oi l decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oi l
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your veh icle where
temperatures stay below freezing point for
l ong periods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing for a short time. This is norma l and is not
a reason to change the o il mo re often than
r ecommended.
D amage or ma lf u nction s du e to lac k of
ma int enance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00 (veh icles with gasolin e engine) or
VW 507 00 (veh icles with diese l engi ne). Yo ur
L im ited New Vehicle Warra nty does not cover
damage or ma lfunctions due to failure to fol­
l ow recommended maintenance and use re­
quirements as set forth in the A udi Owner's
Manual and Warranty

Your dealer will have to deny warranty cover­ age un less you present to the dea ler proof in
the form of Service or Repa ir Orders that a ll
Checking and fillin g 199
scheduled maintenance was performed in a
timely manner.
· Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to prov ide effective lubrication and
cooling o f inte rna l engine components, all in ­
ternal combustion engines consume a certain amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically, engines
with a spec ified break-in period (see
Q page 169) consume more oil during the
break-in pe riod than they consume after o il
consump tion has stabilized.
Under normal cond itions, the rate of oi l con­
sumption depends on the quality and viscos ity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature a nd road conditions. Further fac ­
tors are the amount of oil dilut ion from wa ter
condensation or fue l residue and the oxida ­
tion level of the oi l. As any engine is subject to
wear as mi leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tablished or spec ified. There is no alternative
to regular and frequent check ing of the oil lev­
el, see
Not e.
If the yellow engine oil level warning symbo l
in the instrument cluster
Ill! lights up, you
shou ld check the oil leve l as soon as possib le
with the oil dipstick q page 200 . Top off the
o il at your earliest conven ience
Q page 200.
&_ WARNING
Before you chec k anything in the engine
compartment, always read and heed al l
WARNI NGS
Q .&. in Working in the engine
compartment on page 194 .
