• Methanol fue ls which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fue l system.
• Do not use fuels that fail to meet the specif ied criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
supplier.

• If you experience a loss of fue l economy or driveabi lity and
performance p ro blems due to t he use of o ne of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
d epos it build -up caused by the type of gasol ine y ou use.
A lthough gasoline grades differ from one manufacturer to another,
t hey have certain things in common . A ll gas oline g rades co ntain
substances that can cause deposits to collect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep eng ine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergent Gasol ine. F or mo re

labeled ask the station operator what fuel is being dispensed before
filling up your vehic le .
Service stations offering diesel fuel are generally located on truck
routes or major highways. Directories of diesel fuel stations are
usually available at diese l fuel stations.
Some states in the USA require permits to purchase diesel fuel.
Check with your State Motor Vehicle Department.
Diesel fuel may not be available outside the USA and Canada . Be
su re to check before traveling to other countries .
Winte r ope ra ti on
At temperatures be low 20° F (- 7° Cl, Diesel fuel No. 2 loses its fluidity
due to wax separation, which may c log the fuel filter or tank filter
and keep the engine from running.
To he lp the filter from being clogged by wax, the fue l filter in your
vehic le is automatically preheated. Preheating the fuel fi lter makes
operation of your vehicle poss ible with Diese l fue l No. 2 down to -
10° F (- 24° Cl.
If you expect tempe ratures below 5° F ( -15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is sufficiently winterized for the prevai ling and expected temperatures .
If not winterized or insufficiently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during
the warm -up per iod in winter. It is also normal when whitish -blue
smoke comes out of the tailpipe after starting and dur ing warm-up.
The amount of smoke depends on the outside temperature .
Do not let your diese l eng ine idle unnecessarily after a cold start.
Driving off slowly will shorten the warm -up period.

help prevent the formation of harmful deposits, sometimes called
"s ludge," that over time can lead to expensive repairs.
At the time of printing, engine oi ls available in the U .S . and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
(vehicles with gasoline engine) and VW 507 00 (vehicles with diesel
engine) are synthetic engine oils. This does not mean, however, that
every synthe tic engine oil wi ll meet Audi o il standard VW 502 00
(gasoline engines) and VW 507 00 (diesel engines). So always be
sure that you use an approved oil.
To help p reve nt th e for matio n of ha rmful d epo sit s use only oil wit h
the following sp ecific ati ons print ed on th e oil contain er:
• Gas oline engine s: Audi oil sta ndard VW 502 00
• Dies el en gin es: Aud i oil stand ard VW 507 00
O il container labels may carry the speci fication singly or in combi­
nation with other designations and oil qua lity standards.
Vi sc osity
Engine o ils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasona l
conditions where you drive . You can use o il with a v iscosity grade o f
SAE 5W-40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE 5W-40 is not avai lab le,
you can also use viscosity grade SAE 5W -30 or SAE 0W -40 as long as
it meets Audi oil quality standard VW 502 00 (vehicles with gaso line
engine) or VW 507 00 (vehicles with diesel engine) specifications.
Because engine oil that meets the Aud i o il standard may not be
avai lable everywhere when you need it, we strong ly recommend
that you a lways carry with you an extra quart (liter) of oil that
expressly conforms to the VW 502 00 (vehic les with gaso line engine)
or VW 507 00 (vehicles with diesel engine) specification, in case you
have to top off the oil while on the road.
Ap plie s to veh icles with g asoline eng ine onl y: Only if the level of the
oi l is at or below the min imum mark on the oil dipstick -and no oil that expressly conforms to Audi oi
l standard VW 502 00 specifica ­
tions is availab le -may you top off with a high quality e ngine oi l,
preferably synthetic-based, that meets ACEA A3, ACEA A5 or
ACEA 85 or AP I SL specifications, but even then, on ly in viscos ity
grades SAE 5W-40, SAE 5W -30, or SAE 0W-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 con form to Audi
oi l specification VW 502 00 .
Applies to veh icle s with die sel eng ine only: Only if the level of the
oi l is at or below the minimum mark on the oi l dipstick -and no oil
that expressly confo rms to Aud i oi l standard VW 507 00 specifica ­
tions is available -may you top off with a high quality engine oil, that
meets ACEA C3 or API CF specifications, but even then, only in
v iscosity grades SAE 5W -40, SAE 5W -30 , or SAE 0W-40. However,
during the entire time between oi l change interva ls, never top off
with more than a total of 0.5 qt/liter engine oil that does not conform to Audi oil specification VW 507 00.
For more information abo ut engine oi l that has been app roved for
your vehicle, p lease contact either your authorized Audi dea ler or
Audi Custo mer Relations at 1 (800) 822 -2834 or visit our web site at
www.audiusa.com or www.audicanada.ca . Here you will a lso find a
current list of oils (manufacturers, brand names etc.) that conform
to Audi oi l standard VW 502 00 (vehicles with gaso line engine) or
VW 507 00 (vehicles with diese l engine) .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time in tervals specified in your vehic le's
Warranty
& Maintenance book let. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor ­
mance and can lead to expensive engine repairs.
Changing the oil at the recommended intervals is so very important
because the lub ricating prope rties of oi l decrease gradua lly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your authorized Audi Service Advisor . ..,.
Vehicle care I t •

-~_C_ h_e _c _ k_ i_n ...:::g::;...._ a_n_ d_ f_ i_ll _in -'g:::;.._ ___________________________________________ _
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
temperatures 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 oi l at the recommended intervals
using only engine oil that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or VW 507 00 (vehicles
with diesel engine). Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure to follow recom­
mended maintenance 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 .•
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 interna l
engine components, all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine. Typically,
engines with a specified break -in period (see=>
page 195) 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 consump­
tion may increase over time until replacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oi l
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
with the oil dipstick=> page 229. Top off the oi l at your
earliest convenience =>
page 230.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
=> &. in "Work ing in the engine
compartment" on
page 224.
0 Note
Driving with an insufficient oil level is likely to cause severe damage
to the engine.
[ i ] Tips
• The oil pressure warning display~ is not an indicator of the oil
level. Do not rely on it. Instead, check the oil level in your engine at
regular intervals , preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consu lt your authorized
Audi dealer to have the cause of your concern properly diagnosed .
Keep in mind that the accurate measurement of oil consumption
requires great care and may take some time. Your authorized Audi
dealer has instructions about how to measure oil consumption
accurately. •

Carefully top off with the appropriate oil in 0.5 liter doses.
- Check the oil level again after two minutes::::,
page 229.
Top off the oil again, if necessary.
- Screw the cap back on the filling hole and slide the oil
d ips tick in as far as it will go.
& WARNING
• While topping off, the oil must not come in contact with hot
engine parts -fire hazard!
• The oil filler cap must be properly secured to prevent oil from
being sprayed on the hot engine and exhaust system when the
engine is running -fire hazard!
• If your skin has come in contact with the engine oil, you must
subsequently cleanse it thoroughly.
0 Note
• The oil level must not be above range @-danger of converter or
engine damage! Contact a qualified workshop to draw off oil, if
necessary .
• Audi does not recommend the use of oil additives. They may
damage the engine and adversely affect your New Vehicle Limited
Warranty .
<£> For the sake of the environment
• Under no circumstances can the oil come in contact with the
sewage network or the soil.
• Observe and fol low legal regulations when disposing of empty
oi l containers. •
Changing the engine oil
We recommend that hove your oil changed by an autho ­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always read
and heed all WARNINGS~
& in "Working in the engine compart­
ment" on
page 224.
T he engine oil must be changed according to the intervals specified
in your Warranty
& Maintenance booklet. This is very important
because the lubricating properties of oil diminish gradually during
normal vehicle use.
Under some circumstances the engine oil shou ld be changed more
frequently. Change oil more often if you drive most ly short
distances , operate the vehicle in dusty areas or under predomi­
nantly stop -and -go traffic conditions, or have your vehicle where
temperatures remain below freezing for extended periods . .,_

Checking and filling ---------------~-!':WIii
•
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.
Because of the problem of proper disposal, along with the special
tools and necessary expertise required, we strongly recommend
that you have your oil changed by an authorized
Audi dealer or a
qualified service station.
If you choose to change your oil yourself, please note the following
important information:
& WARNING
To reduce the risk of personal injury if you must change the engine oil in your vehicle yourself :
• Wear eye protection.
• To reduce the risk of burns from hot engine oil, let the engine
cool down to the touch.
• When removing the oil drain plug with your fingers, stay as far
away as possible. Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose, one
large enough to hold at least the total amount of oil in your engine.
• Engine oil is poisonous. Keep it well out of the reach of children.
• Continuous contact with used engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.
0 Note
Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi New Vehicle
Limited Warranty.
<£' For the sake of the environment
• Before changing your oil, first make sure you know where you
can properly dispose of the used oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil, wooded areas, into open streams or down sewage
drains.
• Recycle used engine oil by taking it to
a used engine oil collec­
tion facility in your area, or contact a service station. •
Applies to veh icles: with diesel engine
Important information for vehicles with diesel
engine when adding or changing engine oil

Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Warranty
& Maintenance Booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer 's suggested tire rotation intervals.
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown .:::::, fig. 176.
• Extra care must be taken when rotating direction -specific tires
:::::, page 277.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed. _,,
