Fuel
Petrol grade
Applies to: vehicles with petrol engine

The
correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10%
ethanol

(E10). The petrol grades have different octane
ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ
95
Super,
Premium or
min.
RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­

mended.
If
that
type of fuel is not available,
reg­

ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ
95

Super, Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­

mended.
If
that
type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

© CAUTION
- Do
NOT fuel
your vehicle with
high-ethanol

fuel blends (e.g. E50 or E85). This will dam­
age the fuel system.
- just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock
addi­

tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­

stead.

Diesel fuel
Applies to: vehicles with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel complying with
the EN 590 standard is recommended.
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly.
For this reason, filling stations in some countries
offer winter-grade diesel fuel during the cold

- Make sure you never spill fuel in the
vehi­

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) 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 envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.

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.

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area
oA-

A WARNING
- Switch off the engine.
-Switch off the ignition.

-Applythe
parking brake.
- On vehicles with manual gearbox place the
gear lever in neutral, on vehicles with auto­
matic gearbox move the selector lever to
position P.
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- Wait for the engine to cool down.
- Keep children away from engine compart­
ment.
- Never spill fluids on a hot engine. These
flu­

ids can cause a fire (e.g. radiator
anti­

freeze).
- Take care not to cause short circuits in the
electrical system.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off - risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.

the dipstick all the way in.
A WARNING
- Ensure that no engine oil comes into contact
with hot engine components when topping

up:
this could cause a fire.
- The oil filler cap must be properly closed to
prevent oil from squirting onto the hot en­
gine or exhaust system while the engine is
running - risk of fire!
- Wash your skin thoroughly if it comes into
contact with engine oil.
- The engine oil must never drop below the
marking®
^>Fig.
246- risk of engine dam­

age!

- When topping up the engine oil, make sure
that the oil level is not above the marking

@
^Fig.
246, as this may result in damage
to the catalytic converter or to the engine.
Do NOT start the engine. Contact a qualified
workshop to extract the engine oil if neces­
sary.
- Applies to vehicles which have an oil
dip­

stick with area
(3)^
Fig. 246: If you run your
vehicle on diesel fuel of poorer quality than
EN 590 standard
fuel,
the fuel can get into
the engine oil. In this case, the oil level
gradually rises and the quality of the engine
oil decreases. Once the oil level has reached
the marking
@
or the indicator lamp
E

has come on, the engine oil level must not
be corrected by extracting the surplus oil -

risk
of engine damage! The engine oil must
be changed
^>page
34.
- No additives should be used with engine oil.
Any damage caused by the use of such
addi­

tives would not be covered by the factory
warranty.
© For the sake of the environmen
- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
© Note
Depending on
how
you drive and the condi­
tions in which the car is used, oil consumption
can be up to 0.5
Itr./lOOO
km. Oil consump­
tion is likely to be higher for the first 5,000

km.
The engine oil Level must be checked at
regular intervals, preferably when refuelling
and before setting off on a long trip.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
|
<^page
30. However, we recommend that it
should be checked occasionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter.
