Fuel and filling the tank
228Filling the tankFilling the tankThe flap that covers the tank cap is unlocked and locked
automatically by the central locking.
Unscrewing the tank cap
– Press the left side of the flap to open it ⇒fig. 218 -arrow-.
– Unscrew the tank cap anti-clockwise.
– Hook the cap onto the open flap ⇒fig. 219. Closing the tank cap
– Screw on the tank cap clockwise until it cannot be turned
further.
– Press the left side of the flap to close it (you should hear it click into place).
When the automatic filler nozzle is operated correctly it will switch
itself off as soon as the tank is “full”. Do not try to put in more fuel
after the nozzle cuts out, as this will fill the expansion chamber in
the fuel tank.
The correct fuel grade for your vehicle is given on a sticker on the
inside of the tank flap. Further notes on fuel ⇒page 227 .
The tank capacity of your vehicle is given in the Technical data
section ⇒page 293 .
WARNING
Fuel is highly inflammable and can cause serious burns and other
injuries.•
For safety reasons always swit ch off the auxiliary heating*
before refuelling the vehicle.
•
For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The cani ster could become damaged in an
accident and leak.
•
Observe all relevant statutory regulations on using, storing and
transporting spare fuel canisters.
•
When filling your tank or a spare fuel canister with fuel, do not
smoke and keep away from naked flames. Risk of explosion!
•
If, in exceptional circumstances, you have to carry a spare fuel
canister, please observe the following warnings:
−Never fill fuel into the spare fu el canister with the canister
placed in or on top of the vehicle. An electrostatic charge could
build up during filling, causing th e fuel vapour to ignite. Danger
of explosion. Always place the canister on the ground to fill it.

Technical data
−
Insert the filler nozzle as far as possible into the spare fuel
canister.
− If the spare fuel canister is made of metal, the filler nozzle
must be in contact with the canister during filling. This helps
prevent an electrostatic charge building up.
− Make sure you never spill fuel in the vehicle or in the luggage
compartment. Fuel vapour is ex plosive. Risk of fatal accident!
Caution
•
If any fuel is spilt onto the vehicle, it should be removed immedi-
ately, as it could otherwise damage the paintwork.
•
Never run the tank completely dry. If there is an irregular fuel
supply, misfiring can occur. As a result unburnt fuel can enter the
exhaust system and cause damage to the catalytic converter(s).
•
When filling the fuel tank after having run it completely dry on a
vehicle with a diesel engine the ignition must be switched on for at
least 30 seconds without starting the engine. When you then start
the engine it may take longer than normal (up to one minute) for the
engine to start firing. This is because air needs to be bled from the
fuel system while starting.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has
switched off; this may cause the fuel to overflow if it becomes warm.
Note
The tank flap is not locked when you lock the vehicle from the
inside.
Releasing the tank flap manually
The tank flap can be released manually if the central
locking system should fail to operate.The manual release mechanism is located behind the side
trim on the right of the luggage compartment.
– Open the right-hand side trim.
– Release the ring from its holder and pull the ring
⇒ fig. 220. You should now be able to open the tank flap
in the usual way ⇒page 228 .

Checking and topping up fluids
236otherwise 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. 227. 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 checke d 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 no t 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.
Caution
Radiator sealants must not be added to the coolant. Such additives
could seriously impair the function of the cooling system.Topping up the coolant
Be careful when topping up coolant.– Switch off the engine.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 227 with a
cloth, and carefully unscrew the cap anti-clockwise

Checking and topping up fluids
238Brake fluidChecking brake fluid level
The brake fluid level can be checked at a glance.– Check the fluid level on the brake fluid reservoir
⇒fig. 228. 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 moistu re 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 caus e 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.

Technical data
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appro-
priate container to catch the used brake fluid and dispose of it in the
proper manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free . It is checked as part of the
Inspection Service.
We recommend that you replace a battery once it is older than 5
years.
When an airbag is triggered, the battery will, under certain circum-
stances, be disconnected from the on-board power supply for
safety reasons ⇒ in “General notes on airbag system” on
page 176 .
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will
become inoperative (e.g. electric windows). These functions will
require resetting after the battery is reconnected. For this reason,
the battery should only be disconnected from the vehicle's electrical
system when absolutely necessary.
If the vehicle is not used for long periods
If you do not drive your vehicle for a period of several days or weeks,
the power management will gradually shut off the on-board
systems one by one, or reduce the amount of current they are using.
This limits the amount of power consumed and helps to ensure reli-
able starting even after a long period ⇒page 202 . Please note that certain convenience features, such as the Audi
advanced key*, the remote control key or the electrical seat adjust-
ment may not be available when yo
u unlock the vehicle. These func-
tions will be restored when you switch on the ignition and start the
engine.
Winter conditions
At low temperatures the battery has to work very hard. It also
provides only a fraction of the starting power it has at normal
temperatures.
For this reason, we recommend having the battery checked and
charged if necessary before the start of winter ⇒page 241 .
WARNING
•
All work on batteries requires sp ecialist knowledge. For queries
regarding the vehicle battery please contact an Audi dealership or
other qualified workshop (risk of chemical burns / risk of explo-
sion).
•
The battery must not be opened. Do not attempt to make any
changes to the electrolyte level of the battery. Otherwise, there is
a risk that a mixture of oxygen and hydrogen gas can accumulate
and cause an explosion.Note
If the vehicle is to be left standing for a period of several weeks at
extremely low temperatures, the battery should be removed from
the vehicle. This ensures that it cannot “freeze up” and be
damaged.
