0.5 litres at a time.
– After two minutes check the oil level once again
⇒page 223.
– If the oil level is too low, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick
all the way in.
WARNING
•
Ensure that no oil comes into contact with hot engine compo-
nents when topping up: this could cause a fire.
•
Wash your skin thoroughly if it comes into contact with engine
oil.Caution
•
The oil level must never be above area , as this may result in
damage to the catalytic converter or to the engine. Contact a quali-
fied workshop to extract the engine oil if necessary.
•
No additives should be used with engine oil. Any damage caused
by the use of such additives would not be covered by the factory
warranty.For the sake of the environment
•
Never pour oil down drains or into the ground.
•
Always observe statutory requirements when disposing of
empty oil canisters.
Cooling systemCoolant
The purpose of the coolant is to carry heat away from the
engine. The correct amount of anti-freeze is important to
prevent the cooling system from freezing in winter.The cooling system is filled for life at the factory, so the coolant does
not need to be changed. The coolant consists of a mixture of water
and anti-freeze additive G12+. This is a glycol-based anti-freeze with
anti-corrosion additives.
Anti-freeze additive
The amount of anti-freeze additive required depends on the temper-
atures to be expected in the winter season. If the anti-freeze concen-
tration is too low the coolant can freeze, resulting in failure of the
cooling system and heater.
The cooling system is filled at the factory with the correct amount of
anti-freeze for the country concerned.
In most cases the mixture consists of 60% water and 40% additive.
This mixture gives the necessary antifreeze protection down to –
25 °C and protects the alloy parts of the cooling system against
corrosion. It also prevents scaling and raises the boiling point of the
coolant.

Technical data Countries with warm climate
The coolant concentration must not be reduced by adding plain
water, even in the summer or in warm climates. The concentration
of the anti-freeze additive must always be at least 40%.
Countries with cold climate
If greater anti-freeze protection is required in very cold climates, the
proportion of the anti-freeze additive G12+ can be increased. A
concentration of 60% offers protection down to about -40 °C. The
concentration of the antifreeze additive must not be more than 60%,
otherwise this would reduce the antifreeze protection. In addition,
the cooling effect will be adversely affected.
Vehicles for export to countries with a cold climate (such as Sweden,
Norway and Finland) are supplied with antifreeze protection down
to about -35 °C. The concentration of the antifreeze additive for
these countries should always be at least 50%.
Caution
•
It is advisable to have the cooling system checked before the
winter season to make sure that the antifreeze concentration is
adequate for the conditions to be expected. This applies particularly
if you intend to take the car into a colder climate zone. If necessary,
have the anti-freeze concentration increased to 50 - 60% as required.
•
Use only anti-freeze additive G12+, an additive meeting the spec-
ification “TL-VW 774 F ”. Other additives may give considerably infe-
rior corrosion protection. The resulting corrosion in the cooling
system can lead to a loss of coolant, causing serious damage to the
engine.
•
The coolant additive G12+ can be mixed only with additives G11
and G12.
Checking coolant level
The coolant level can be checked at a glance.– Switch off the ignition.
– Read off coolant level on radiator expansion tank
⇒fig. 215. When the engine is cold it should be between
the “MIN” and “MAX” marks. When the engine is hot it
may be slightly above the “MAX” mark.The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp in the instrument
cluster ⇒page 32. However, we recommend that it should be
checked occasionally.
Coolant losses
Any loss of coolant normally indicates a leak in the cooling system.
In this case the cooling system should be inspected by a qualified
workshop without delay. It is not sufficient merely to top up the
coolant.
If there are no leaks in the system, a loss of coolant can only occur
if the coolant boils and is forced out of the system as a result of
overheating.

Brake fluidChecking brake fluid level
The brake fluid level can be checked at a glance.– Check the fluid level on the brake fluid reservoir
⇒fig. 216. It should always be between the “MIN” and
“MAX” marks.In right-hand drive vehicles the brake fluid reservoir is on the other
side of the engine compartment.
The fluid level may drop slightly after a period of time due to the
automatic compensation for brake pad wear. This is quite normal.
However, if the level goes down noticeably in a short time, or drops
below the “MIN” mark, there may be a leak in the brake system. If
the fluid level in the reservoir is too low, this will be indicated by the
brake warning lamp ⇒page 31. If this should happen, take the car
to a qualified workshop immediately and have the brake system
inspected.
Changing brake fluid
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moisture from the atmosphere. If the
water content in the brake fluid is too high, this may cause corrosion
in the brake system over time. In addition, the boiling point of the
brake fluid will be considerably reduced. This could adversely affect
the braking ability in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has
to be changed.
It is advisable to have the brake fluid changed as part of a regular
Inspection Service at your Audi workshop. They are familiar with the
procedure and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Qualified
workshops know that the brake fluid “DOT 4” is approved by Audi.
The brake fluid must be fresh and unused.
WARNING
•
Brake fluid is poisonous; store it in the sealed original container
in a safe place out of reach of children.
•
Heavy use of the brakes may cause a vapour lock if the brake
fluid is left in the system for too long. This would seriously affect
the efficiency of the brakes and the safety of the car – risk of acci-
dent.Caution
Please note that brake fluid will attack the paintwork on contact.

Downloaded from www.Manualslib.com manuals search engine Wheels and tyres 232Wheels and tyresWheelsGeneral notes–When driving with new tyres, be especially careful during
the first 500 km.
– If you have to drive over a kerb or similar obstacle, drive
very slowly and as near as possible at a right angle to the
kerb.
– Inspect the tyres regularly for damage (cuts, cracks or
blisters, etc.). Remove any foreign bodies embedded in
the treads.
– Damaged wheels and tyres must be replaced immedi-
ately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they
rotate in the same direction when put back.
– When removed, the wheels or tyres should be stored in a
cool, dry and preferably dark place.New tyres
New tyres do not give maximum grip straight away and should
therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km. This will also help to make the tyres last
longer.
The tread depth of new tyres may vary, according to the type and
make of tyre and the tread pattern.Concealed damage
Damage to tyres and rims is often not readily visible. If you notice
unusual vibration or the car pulling to one side, this may indicate
that one of the tyres is damaged. Reduce speed immediately if there
is any reason to suspect that damage may have occurred. Inspect
the tyres for damage. If no external damage is visible, drive slowly
and carefully to the nearest qualified workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on
tyres with directional tread. Always note the direction of rotation
indicated when mounting the wheel. This guarantees optimum grip
and helps to avoid aquaplaning, excessive noise and wear.
Tyre service life
Correct inflation pressures and sensible driving habits
will increase the service life of your tyres.– Check the tyre pressures at least once a month.

WARNING
After repairing a tyre please note the following points:•
Do not drive faster than 80 km/h.
•
Avoid heavy acceleration, hard braking and fast cornering.
•
Vehicle handling could be impaired.
•
Tyres which have been sealed using the TMS are only suitable
for temporary use. Damaged tyres must be renewed.
•
The TMS must NOT be used,
−on cuts and punctures larger than 4 mm
−if the wheel rim has been damaged
−if you have been driving with very low pressure or a
completely flat tyre
•
Seek professional assistance if the repair of a tyre puncture is
not possible with the sealing compound.
•
Do not allow the sealant to come into contact with your eyes,
skin or clothing.
•
If you do come into contact with the sealant immediately rinse
the eyes or skin affected with clean water.
•
Change clothing immediately if it becomes soiled with the tyre
sealant.
•
Make sure you do not breathe in the fumes!
•
If any of the tyre sealant is accidentally ingested, immediately
rinse the mouth thoroughly and drink lots of water.
•
Do not induce vomiting. Immediately contact a doctor!
•
If any allergic reactions should occur get medical help immedi-
ately.
•
Keep the sealant away from children.
For the sake of the environment
Used bottles of sealing compound can be returned to an Audi dealer
for disposal.
Note
•
If sealant should leak out, leave it to dry. When it has dried, you
can pull it off like a piece of foil.
•
Observe the expiry date stated on the sealing compound can.
Have the sealing compound exchanged by a qualified workshop.
Repairing a tyrePreparations
– If you have a flat tyre, stop the car well away from moving

– Ensure that all passengers leave the vehicle and move
away from the danger area ⇒.
– Take the tyre sealant can and the electric compressor out
of the luggage compartment ⇒page 245.
– Fix the sticker “max. 80 km/h”, which is included with the
tyre sealant can, onto the instrument cluster where the
driver will see it.
Filling the tyre
– Shake the tyre sealant can well.
– Screw the enclosed filling hose onto the sealant can as
far as it will go. This will automatically pierce the foil
sealing the can.
– Take the valve cap off the tyre valve and use the enclosed
valve insert tool to unscrew the valve insert ⇒page 248,
fig. 228.
– Place the valve insert onto a clean surface.
– Remove the sealing plug from the filling hose and insert
the hose into the tyre valve.
– Hold the tyre sealant can upside down and fill the
complete contents of the can into the tyre.
– Then disconnect the hose and screw the valve insert
firmly back into the tyre valve.
Inflating the tyre
– Screw the filling hose of the electric compressor onto the
tyre valve and plug the connector into the cigarette
lighter.– Pump the tyre up to 2.0 to 2.5 bar and monitor the pres-
sure shown on the pressure gauge.
– If the tyre pressure remains lower than the value speci-
fied above drive the vehicle approx. 10 metres forwards
or backwards, so that the sealant can spread evenly in
the tyre. If the pressure is still lower than the specifica-
tion the tyre is too badly damaged and cannot be
repaired using the tyre sealant.
Final checks
– After about 10 minutes stop to check the tyre pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly
damaged. Do not drive on. You should obtain profes-
sional assistance.
WARNING
•
If you have a puncture in moving traffic, switch on the hazard
warning lights and place the warning triangle in a visible location.
This is for your own safety and also warns other road users.
•
Make sure your passengers wait in a safe place (for instance
behind the roadside crash barrier).
•
Please observe the manufacturers' safety notes on the
compressor and the instructions supplied with the tyre sealant
can.
•
If it was not possible to build up a tyre pressure of 2.0 bar
within 6 minutes this means that the tyre is too badly damaged.
Do not drive on.
•
Seek professional assistance if the repair of a tyre puncture is
not possible with the sealing compound.
•
If tyre pressure is less than 1.3 bar after driving about 10
minutes, the tyre is too badly damaged. Do not drive on. You
should obtain professional assistance.
