8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving 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 on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 211,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 221, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­

Engine oil
· Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The eng ine in your Audi is a sophist icated
power plant that was b uilt to exacting specifi­
cations . Th is engine needs the right k ind of
engi ne oil that meets specifica tions regard ing
quality a nd v iscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changing oil within the t ime and mile age
i n tervals prin ted in you r vehicle's Warr anty
&
Maintenance booklet matters a lot more to ­
day tha n it did years ago . Aud i has deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle 's engine w ill
get the lubr ication it needs for proper opera-
t ion . ..,_

Modern eng ine lubrication has taken a quan­
tum leap in the last few years . Many synt hetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional pet role­
um-based o ils, making them a smart choice
for use throughout the life o f your Audi .
W hether you use synthetic or petroleum­
based engine oil, the oil that you use must
c o nform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine running smoothly and help prevent the for­
mat ion of harmfu l deposits, sometimes called
"sludge", that ove r time can lead to expensive
r epairs .
At the time of pri nting, engine o ils available in
the U .S . and Canada that meet the exacting
specifications of Audi oi l standard VW 502 00
are synthetic engine oils. This does not mean, h owever, that every synthetic engine oil w ill
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oi l.
To help prevent the format ion of harmful de­
posits use only oi l with the fo llowing spec ifi­
cations printed on the oil container:
Audi oil standard VW 502 00
O il conta iner labels may carry the specif ica­
tion s ingly or in comb inat ion w ith other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper v iscosity grade oi l for your
engine depends on cl imactic or seasonal con­
d itions where you dr ive. You can use oil with a
viscosity grade of SAE SW40 across all tem­
pe rature ranges for normal d riving conditions .
However, if eng ine oi l viscosity grade SAE
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specifications.
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we st rongly recomme nd
that you always carry with you a n ext ra quart
Checkin g and fillin g 219
(li ter) of oil that exp ress ly con forms to the
VW 502 00 specification, in case you have to
top
off the o il while on the road.
Only if the level of the o il is at or be low the
minimum mark -and no oi l that expressly
confo rms to Audi oil standard VW 502 00
spec ifications is available -may you top
off
with a h igh quality engine o il, preferab ly syn ­
thet ic-based, that meets ACEA A3 or API SM
specifications, but even then, only in v iscosity
grades SAE SW-40, SA E SW-30, o r SAE
OW-40. However, dur ing the entire time be­
tween o il cha nge inte rva ls, never top
off with
more than a tota l of 0. 5 q t/liter engine o il
that does not con form to A udi oil specification
vw 502 00.

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
T he eng ine oi l and o il f ilter m ust be changed
according to the mileage (kilometers) and
time intervals specified i n your vehicle's War ­
ranty
& Maintenance booklet. Do not exceed
these interva ls - harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changi ng the oil at the recommended inter­
vals is so very important beca use the lubricat­
ing propert ies of oil decrease gradually during
norma l veh icle use . If you a re not sure when
you have your o il cha nged, ask your author­
ized Audi Se rv ice Adv isor.
Under some circumstances the engine oil
shou ld eve n be changed more frequent ly.
Change oil more often if you dr ive most ly
sho rt distances, operate the veh icle in dusty
areas o r most ly under stop-and-go traff ic con-
di tions, o r when you use your vehi cle where .,..

temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine 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 provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
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 play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le

convenience ¢

Changing the engine oil
We recommend thot hove your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
ING S ¢ & in Working in the engine compart­
ment on page 216.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradually during normal vehicle use .
Under some circ umstances the engine oi l
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and -go traffic con ­
d itions, or have your veh icle where tempera­
tures remain below freez ing fo r extended pe­
riods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the oil mo re often than
recommended.
Because of the problem of proper disposal ,
a long w ith the special tools and necessary ex­
pertise required, we strong ly recommend that
you have your o il changed by an authorized
Audi de ale r or a qualified service station.
If you cho ose t o c han ge your oil yours elf ,
please note the following important informa­
tion :
A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run­
n ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the rea ch of childre n.
- Continuous contact with used eng ine o il
is harmfu l to your sk in. Always protect
your skin by washing oil off tho ro ughly
with soap and wate r.
@ Note
Neve r mix oil additives with your engine
oi l. These additives can damage your en­
g ine and adversely affec t you r A ud i L imit­
ed New Veh icle War ranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you can prope rly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper ­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams o r down
sewage drains.
- Recycle used engi ne oil by taking it to a
used engine oil collection facility in you r
area, or contact a service station.

Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G13 antifreeze with
anticorrosion additives (50% for USA models;
60% for Canadian models). This mixture both
assures the necessary frost protection and
protects metal components in the engine's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35 °C)USA
- -40 °F ( - 40 °C) Canada.
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
¢ .&. in Working in the engine
compartment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in-
Checking and filling 223
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle .
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
