and can damage the leather surface as well as
weaken seams .
The leather sho uld be cleaned reg ularly as
needed. After having been used for a re latively
l ong time, your leather seats will acquire a
rich aged finish. This is a characteristic of nat­
ura l leather and a sign of true quality .
I n o rder to maintain the va lue of th is natura l
p roduct over the life of your vehicle, you
should follow the recommendations below :
(D Note
-To keep yo ur leather from bleach ing out,
do not a llow it to be exposed to bright
sunlight for long periods of time. If you
have to leave the vehicle parked outside
for long periods, cover the leather to
protect it from d irect exposure to sun­
light.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on be lts can
leave permanent scratches or scrape
marks on the surface of the leather .
- After each time you clean the leather and
at regular inte rva ls, use a leather preser­
vat ive cream that conta ins UV-blockers
and that works into the leather. This
c ream will nourish and moistur ize the
l eather, helping i t to brea the and stay
supple .
It also helps to b uild up a protec­
tive coating on the s urface .
- Clean the leather every 2 -3 months,
and clean any areas that get soiled.
- Remove fresh mar ks made by ba llpoint
pens, ink, lipstick, shoe polish, e tc. as
soon as possib le .
- Preserve the colo r of the leather as need­
ed by using a special colored leather care
cream to touch up areas of uneven co lor.

Cleaning and caring for leather
upholstery and trim
Applies to vehicles : with natural lea ther
Natural leather requires special care and at­
tention .
Normal clean ing
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth .
More stubborn dirt
.. More st ubborn dirt can be removed using a
cloth saturated with a mild soap solut ion (2
tablespoons mild liquid soap).
.. Never allow the soap solution to saturate
the leather, and make certain that no water soaks into the seams.
.,. Wipe off the soap so lution with a soft, dry
cloth.
Cleaning spots
.. Remove fresh wat er-bas ed spots (such as
coffee, tea, juices, blood) with an absorbent
cloth or paper towel.
.. Remove fresh
grea se or oil-ba sed spot s
(such as bu tte r, mayonnaise, chocola te) with
an absorbent cloth or paper towel, or use
the cleaner from the leather care kit if the
spot has not yet penetrated into the surface
of the leather.
.. Use an oil/grease dissolving spray, if
oil/
grease spot s ha ve dried on.
.. Remove specific k inds of spots (ballpoint
pen, felt marker, fingerna il polish, water­
based pa int, shoe po lish, etc.) with a spot
remover specifically fo rmu lated for leather.
Leather care
.. Every half year use an approved leather care
product (available from your authorized
Aud i dealer) to care for the leather.
.,. App ly the product very spar ingly.

~ page 202.

-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(D Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in veh icles with flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l engines
can cause severe engine damage .
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Veh icle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Fuel supply and filling your fuel tank 215
Ethanol fuel (Bio-ethanol)
Applies to veh icles: w it h flex ible fue l en gin e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap .
Vehicles with flexible fuel engines may be op­
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95) . T he vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha ­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in ve ry
low temperatures. This fuel evaporates again
when the engine is warmed up.
II Ple ase warm up engine.
If the driver message appears in the instru­
ment cluster disp lay, drive with a warm en­
gine to reduce the oil level.
(D Note
- Never fill with methanol or with a higher
percentage of b io-ethanol than 85%
(E85). A h igher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fue l tank complete ly w ith un­
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fuel tank comp letely with unleaded pre­
mium grade gasoline and dr ive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
pers ists.

220 Checking and filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com ­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans- mission to
"P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine .
- Minimize exposure to emission and
chemical hazards

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 sophisticated
power p lant that was bu ilt to exacting specifi­
cations . This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changi ng oil within the t ime and mileage
i n tervals printed in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to ­
day than it did years ago . Audi has developed
a specia 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-
tion. .,..

222 Check ing and filling
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum ­
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 to he lp 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
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
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
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is a t or be low the
min imum mark -and no oi l that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top
off
with a high quality engine o il, preferab ly syn ­
thet ic-based, tha t mee ts ACEA A3 or API SM
specifications, but even then , only in v iscosity
grades SAE SW-40 , SAE SW-30, o r SA E
OW-40. However, dur ing the entire time be­
tween oil change inte rva ls , never top
off with
more than a total of 0.5 q t/ liter engine o il
t h at does not con form to Audi oi l specification
vw 502 00.

www.aud icanada .ca. Here you w ill also find a
current list of oils (manufacturers, brand
names e tc.) tha t conform to Audi oil s tanda rd

Changing the engine oil
The eng ine oi l and oil fi lter must be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil ca n reduce eng ine performance and
can lead to expensive engine repa irs .
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­ ing proper ties of oil decrease gradually during
norma l veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
shou ld even be cha nged more frequent ly .
Change oil more often if you drive mostly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
di tions, o r when you use your vehi cle where .,..

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies wi th A udi oi l standard
VW 502 00 . Your Limited New Vehicle War ­
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty

the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 194) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 223
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
1\1 in the instrument cluster lights up , you
sho uld check the oil leve l as soon as possib le

226 Check ing and filling
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-basedcoolant additive G 13 antifreeze with
anticorrosion add itives (SO% for USA mode ls;
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
a lso raises the boiling point of the coolant .
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
p ro po rti on of c ool ant add it iv e mu st b e at
lea st 50 % but not mo re th an 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
