0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint.
• When you wash your car in the winter: if you rinse your vehicle with
a hose, be careful not to aim the stream of water directly at locks, or
at door or hatch openings -they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish.
• You should remove debris (such as insects) from the headlight
lenses on a regular basis, for example when refueling your vehicle .
Never use a dry cloth or sponge to clean the headlights. Only use wet
cloths or sponges to prevent scratches .
It is best to use soapy water.
<£> For the sake of the environment
In the interest of the environment, the vehicle should only be washed
in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS=>
& in "General infor­
mation" on
page 256 .
- Always follow the operating instructions for the power
washer. -
Make sure that the jet on the spray hose produces a "fan
shaped spray".
- Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure
and the spraying distance . Maintain a sufficient distance to
soft materials such as rubber hoses and sound/vibration deadening
materials (particularly on the underside of the engine hood). Do not
use a jet which sprays water in a
direct stream or one that has a
rotating jet.
Water temperature should not exceed 140
°F (60 °() .
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time. Damaged and weakened tires can fail and cause accidents
and personal injury.
0 Note
To avoid damaging your vehicle, always make sure that there is suffi­cient distance between the spray head and soft materials like rubber
hoses , plastic parts and sound-deadening materials. Never aim the
spray head at the same point for a long time. This also applies to
cleaning headlights and painted bumpers. Remember: the closer the
nozzle is to the surface of the material, the greater the stress on the
material. •

Plastic and vinyl
Plastic needs special care.
Use a clean, damp cloth or sponge to remove dust and light surface
dirt. For other soil, use a lukewarm all-purpose cleaning solution or a
mild saddle soap for vinyl trim . Remove water spots and traces of
soap with a clean, damp cloth or sponge. Use a clean, soft cloth to rub
dry.
Grease, tar or oil stains can be removed with a clean cloth or sponge
soaked with all-purpose cleaner or with a solvent designed especially
to clean vinyl.
Occasionally apply a colorless vinyl or leather preservative to retain
the material's luster and pliability.
& WARNING
Always read and heed all WARNINGS and other information
:::> page 256. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
aluminum surfaces. Chrome care products and alkaline cleaners will
attack aluminum surfaces and can damage them over time .
& WARNING
Always read and heed all WARNINGS and other information
=>page 256. •
Touch-up paint
Minor paint damages should be touched up immediately.
- Use either a touch-up paint stick or spray paint to cover
minor scratches and nicks.
Your authorized Audi dealer has touch-up paint for minor scratches
and stone chips. Scratches should be touched up soon after they
occur to prevent corrosion.
If a spot starts to rust, however, a simple touch-up job will not be
enough. The affected surface must be sanded smooth and coated
with an anti-rust primer before the painted finish can be restored.
The number for the original vehicle paint can be found on the vehicle identification label=>
page 336.
& WARNING
Always read and heed all WARNINGS and other information
=>page 256. •
Windows
Clear vision to all sides.
Clean all windows regularly to remove road film and car wash
wax buildup.
- Remove snow from windows using a brush.
- Use a plastic ice scraper to remove ice from windows and
mirrors.
- Remove other residue on the windows with a spray-on glass cleaner.
- Wipe the windows dry with a clean piece of cloth or
kitchen paper towel.

____________________________________________ C_l_e _a_ n_ i n--= g=--- a_n_ d----' p,__ r_o _t_ e_ c_ t_ i _o_ n __ _
The best way to remove snow from windows and mirrors is to use a
brush. Use a non-abrasive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mirrors.
Th e windows must not be cleaned with insect remover or wax since
these can interfere with the function of the windshie ld wipe r blades
(chatter).
Oil , grease, or silicone residue can be removed with
glass cleaner or
silicone remover. However, wax residue requires the use of a specially
formulated solvent . P lease contact your authorized Audi dea le r for
advice on safe products for wax removal.
Windows should also be cleaned on the inside at regular intervals .
Never dry windows w ith the same chamo is that you use to dry painted
surfaces. Wax residue on the chamois can impair vision through the
windows.
& WARNING
• Always read and heed all WARNINGS and other information
=> page 256.
• The windshield must not be treated with water-repellent
materials. They can increase glare under poor visibility conditions
such as wetness, darkness, or when the sun is low on the horizon.
In addition, they can cause the windshield wipers to chatter.
0 Note
• Never use warm or hot water to remove snow and ice from
windows and mir rors . This could cause the glass to crack.
• To prevent damage to the wires of the rear defogger, do not place
any adhesive stickers on the inside of the rear window over the wires.
• T o help prevent dirt from scratching the window, a lways scrape in
a forward direction -pushing the scraper away from you -never back
and forth.
• Water leaking from the inside of the rear windows may damage
sensitive e lectrica l components located either under the rear parce l
Safety first
shelf or in the rear trunk area. Always ensure that water never leaks
t hrough the body section of the vehicle . You can do this by using
waterproof protection over the vehicle's electrical components (e .g.
when installing window tinting).

Fabrics and fabric coverings
Fabrics and fabr ic coverings (e.g. seats , door tr im panels, etc.) should
be cleaned at regular intervals with a vacuum cleaner . This removes
surface dirt particles which could become embedded in the fabric
through use . Steam cleaners should not be used, because the steam
tends to push the dirt deeper into the fabric and lock it there .
Normal clean ing
Genera lly, we recommend using a soft sponge or a lin t-free
microfiber cloth to the clean fabric . Brushes should only be used for
carpets and floor mats, since other fabric surfaces could be harmed
by brushes . _,,

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.
Safety first
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 SW40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE SW40 is not available, you
can also use viscosity grade SAE SW-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 SW-
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. ..

-Checking and filling
-------=----- -=-----------------------------------------
For more information about engine oil that has been approved for
your veh icle, 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 o ld engine oil can reduce engine performance and can
lead to expensive engine repa irs.
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 Adviso r.
Under some circumstances the engine o il should even be changed
more frequent ly. Change oil more often if you drive mostly short
distances, operate the veh icle in dusty areas or mostly under stop­
and-go traffic conditions, or when you use your vehicle where temper­
atures stay below freez ing po int 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 essentia l that you change yo ur 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 fa ilure 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. •
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
eng ine components, all inte rnal comb ustion eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ifican tly over the life of the engine. Typically,
engines with a specified break-in period (see~
page 246) consume
more oil dur ing the break- in period than they consume after oil
consumption has stab ilized.
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
eng ine 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 variab les 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 279. Top off the oil at your earliest convenience~ page 279.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNINGS ~
