• Never use a power washer to clean the power top itself.
• To avoid damaging your vehicle, always make sure that there is
suff icient distance between the spray head and soft mater ials l ike
rubber hoses, plastic parts and sound -deadening materials. Never
aim the spray head at the same po int for a long time. This also applies
to cleaning headlights and painted bumpers. Remember: the closer
the nozzle is to the surface of the mater ial, the greater the stress on
the material. •
Power top care
The power top requires special care.
Keeping your top looking great and mak ing certain that it lasts a long
time depend to a great extent on proper use and care. Remove bird
droppings as soon as possible, since the corrosive chemicals in them
wi ll cause the rubber impregnation in your top to swell and possibly
allow the fabric to leak.
With
normal soiling, all you need to do is clear the top with a soft
brush and clear water. Always brush in the direction of the fabric from
front to rear.
If the top is
very dirty and has spotted areas clean it with a br ush
using a convert ible top cleaner . Always brush in the direction of the
fabric from front to rear. Rinse with plenty of clear water, and allow
the top to air -dry .
Chamois are not sui tab le for drying the top .
Never use gasoline, spot remover, benzene, paint thinner or solvents
to remove spots. We recommend that you only use cleaners espe­
cially formulated for use on convertib le tops, and that you follow the
produce use directions carefully . Authorized Audi deals can provide
detailed information.

Fuel recommendation
The f ue l recommended for yo ur vehicle is unleaded premium grade
gasoline. See also=>
page 342, "D at a". Aud i recommends using TO P
TIER Detergent Gasoline with a m inimum octane rating of 91 AKI (9S
R ON ). For more inform ation on TOP TIE R De tergent Gasoline, please
go to the official website (www .topt iergas .com) .
Th e recommended gasoline octane rating for your engine can a lso be
found on a labe l located o n the i nside of t he fue l fille r flap. This rating
may be specified as AKI o r RON .
Yo ur vehicle may a lso be opera ted u sing unle aded reg ula r gaso line
w ith a minim um octane rating of 87 AKI/91 RON. However, using 87
AKI/91 RON octane fue l will slig htly reduce engi ne pe rformance.
Use unleaded gasoline only . Unleaded gaso line is available
througho ut the USA, Canada, and in most E uropean countries. We
recommend tha t you do not take your ve hicl e to a reas or countries
where unleaded gasoline may not be availab le.
For mo re in format io n on refueling your vehi cle, see =>
page 275 .
Octane rating
Octane r atin g indica tes a gaso line's ability to resis t eng ine dam ag ing
"knock" caused by premature ignition and detonatio n. Therefore,
buying the co rr ec t gr ade o f gas oline is very im port an t to help prevent
poss ible engine damage and a loss of engi ne performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings that can usually be fou nd on the filler
pump: •
Premium Grade : 9 1 -96 AKI
• Regu lar Grade: 87 - 90 AKI
E xp lanation o f the a bbrev iations:
AKI= Anti Knock Index= (R +M)/2 = (RON+MON)/2
RON= Resea rch Octane Number
M ON= M otor Octane Number.

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 stations where the seasonal adjustment is
more likely to be made in time.

• Methanol fuels which do not meet these requirements may cause
corros ion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unab le to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
s u pplier.
• Do not use fue l 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 responsi ­
bility of Audi and are not covered under the New Vehicle or the Emis­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveability and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended f uel. •
Gasoline additives
A major concern among many auto manufacturers is carbon depos it
build -up caused by the type of gasoline you use.
Safety first
Although gasoline grades differ from one manufacturer to another,
t hey have certain things in common. All gasoline grades contain
substances that can cause depos its to collect on v ital engi ne parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean, they
are not equally effective .
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended per iod of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoothly and reliably. Choosing the right oil and changing oil
within the time and mileage intervals printed in your vehicle 's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
that will help assure that your vehicle 's engine will get the lubrication
it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine lubri­
cation that can outlast traditional petroleum-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
help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits , sometimes called "sludge", that
over time can lead to expensive repairs.
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil. To help prevent the formation of harmful deposits
use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina­
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
conditions where you drive. You can use oil with a viscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE 5W40 is not available, you
can also use viscosity grade SAE 5W -30 or SAE OW -40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail­
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica­
tions is available - may you top off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE 5W-
40, SAE SW-30, or SAE OW-40 . However, during the entire time
between oil change intervals, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that has been approved for
your vehicle, please contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www .audicanada.ca. Here you will also find a
current list of oils (manufacturers, brand names etc.) that conform to
Audi oil standard VW 502 00. ._

Changing the engine oil
The engine oil and oil filter must be changed according to the mileage
(kilometers) and time intervals specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from old engine oil can reduce engine performance and can
lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lubricating properties of oil decrease gradually during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freezing point for long periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not a
reason to change the oil more often than recommended.
Damage or malfunctions due to lack of maintenance
It is essential that you change your oil at the recommended intervals
using only engine oil that complies with Audi oil standard
VW
502 00 . Your Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to follow recommended main­
tenance and use requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet. Your dealer will have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
Safety first
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 250) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption 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
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As any
engine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster _ lights up, you should check the oil level as soon as possible
~ page 284. Top off the oil at your earliest convenience~ page 284.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
