•
High temperatures, as from exposure to intense sunlight, intens ify
the corrosive effect particularly when humidity is high as well.
Under ce rtain circumstances ,
weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed, preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and other information

Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However , the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
Before going through a car wash, be sure to take the usual precau ­
tions such as closing the windows and panoramic sliding sunroof *.
Remove antenna if applicable.
If you have installed additional accessories on the vehicle -such as
spoilers, roof rack , etc. -it is best to ask the car wash operator if
these should be removed .
& WARNING
Always read and heed all WARNINGS and other information
=> page 206. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start washing, make sure you have read and
understood the WARNINGS=:>
& in "General informa ­
tion" on
page 206 .
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom , using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door sills and other
regions exposed to road dirt. In this way , you will not scratch the
paint with coarse particles imbedded in the sponge the next time
you wash the car.
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms. You may cut yourself on sharp-edged metal parts . .,

rotating j et.
Water temperature shou ld not exceed 140 °F (60 °Cl.
& WARNING
Never wash tires with a jet that sp ray s water in a dire ct stream .
This could c ause invi sible damage to the tire s and we ake n them ,
even if the spray i s from a relatively long distan ce and for a short
time . D amag ed and weakened tires can fail and cau se ac cident s
a nd p erson al injury.
0 Note
To avoid damaging your vehic le, always make sure that there is
suffic ient distance between the spray hea d and so ft m ateria ls like
rubber hoses, plastic parts and sound -deadening materials . Never
aim the spray head at the same p oint for a l ong time . This a lso
applies to cleaning head lights and painted bumpers . Remember:
t he c loser the n ozzle is to the surface of the materia l, the greater the
stress on the material. •

Waxing
Wax prote cts the vehicle's paint.
- Use a manually applied car wax occasion ally to protect
t h e paint.
A good wax coating protects the vehicle paint to a large extent
against th e environm ental factors listed under~
page 206,
"Washing" and even against slight scratches .
You can use a liquid car wax to protect your paint as soon as one
wee k after you r vehic le has been delivered .
Even if you regularly use a
waxing process in automatic car washes,
we recommend that you manua lly app ly a coat of wax to give the
paint e xtra protection, par ticu lar ly if water no longer beads on the
clean paint.
Protec t plastic body parts with car wax in the same way as the
vehic le body.
During warm weather dead insects tend to col lect on the front
bumpe r and on the forward area of the hood. They are much easie r
to remove from paint that is waxed
often.
& WARNING
Always read and heed all WARNINGS and other information
~ page 206 .
0 Note
Do not use ca r wax on
• matte or anodized meta l trim
• rubber or rubber -like trim. •
Polishing
Polishi ng resto res the gloss to the p aint.
Po lish your vehic le on ly if the paint has lost its shine and the g loss
cann ot be brought back wi th wax .
I f the polish used does not contain preservative compounds , the
paint must be waxed afterwards~
page 209, "Waxing".
& WARNING
Always read and heed all WARNINGS and other information
~ page 206 .
0 Note
Do not treat matte anodized metal trim, plastic or rubber parts with

Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them .
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your authorized Audi dealer.
• Always read and heed all WARNINGS and other information
=:, page 206. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine =:> &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
3l, or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well . It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=:> page 217 . .,,_
31 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.

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 cool ing 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 197) consume
more oil during the break-in period than they consume af ter oi l
consumption has stabi lized .
Unde r 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 o il. As
any engine is subject to wear as mileage builds up, the oil consump ­
tio n may increase over time unt il rep lacement of worn components
may become necessary.
W ith all these variables coming into play, no standard rate of oil
consu mption can be estab lished or specified. There is no a lternative
to regular and frequent checking of the oil level, see
Note .
If the yellow engi ne oil level warning symbol in the instrume nt
cluster lights up, you should check the oil level as soon as
poss ible
with the oil dipstick~ page 229 . Top off the oil at your
earliest convenience~
page 230.
& WARNING
Before you che ck anything in the eng ine comp artment , alw ay s
read and heed all WARNINGS
~ & in "Working in the engine
c ompartment " on
page 22 5.
0 Note
Driving with an insufficie nt o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pressure warning displ ay ce,. is not an indi cat or of the oil
level . Do not rely on it. Instead , check the oil level in your engine at
regular interv als , prefe rably ea ch time you refuel , and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amoun ts of oil, we recommend that you consu lt your authorized
Audi dealer to have the cause of your concern proper ly diagnosed .
Keep in mind that the accura te m easuremen t of oil consumption
requires great care and may take some time . Your authorized Audi
dea ler has instructions about how to measu re oil consumption
accurately .•

• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely 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.
Fig . 175 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 225.
Turn off the ignition.
Read the engine coolant level from the coolant expan­
sion tank==> fig. 175. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking.
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 226.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..
