vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
CD CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if you fill up with the
wrong type of fuel, as this could damage

as far as the stop ¢ Fig. 208 and ensure it is
properly engaged .
... Start refuelling. When the automatic filler noz­
zle 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.
.., When the fuel filler pump switches itself off,
wait for 5 seconds before pulling out the filler
nozzle so that any remaining fuel can flow into
the tank opening.
... Close the tank flap. Make sure you hear it click
into place.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel ¢ page 241.
The tank capacity of your vehicle is given in the
Technical data section ¢ page 288 .
A WARNING
Fuel is highly inflammable and can cause seri­
ous burns and other injuries.
- When filling your tank or a spare fuel canis­
ter with fuel, do not smoke and keep away
from naked flames -risk of explosion!
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- If, in exceptional circumstances, you have to
carry a spare fuel canister, please observe
the following warnings:
- Never fill fuel into the spare fuel canister
with the canister placed in or on top of the
vehicle. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite -risk of explosion! Always
place the canister on the ground to fill it.
- 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 �

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-
244 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 symbol
C for the diesel particulate filter lights up
¢page 17.
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 ¢ A .

of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle will
otherwise start moving immediately and
could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of

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.
248 CD
CAUTION
- The engine oil must never drop below the
marking (!)¢ Fig. 215 -risk of engine dam­
age!
- When topping up the engine oil, make sure
that the oil level is not above the marking
@ ¢Fig. 215, 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® ¢Fig. 215: 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 II
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 18.
- 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 environment
- 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 Ltr./1000 km. Oil consump­
tion on RS models can be up to 0.8 ltr./1,000
km. Oil consumption is likely to be higher for
the first 5,000 km. For this reason the engine
oil level must be checked at regular intervals,
preferably when filling the tank and before a
journey.

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 14. 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.
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive Specification
G13 TL 774
J
G12++ TL 774 G
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too low, the coolant
can freeze and cause engine damage.

Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. 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.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- 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!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system -risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.

.&_ WARNING
Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury and
chemical burns in addition to danger of acci­
dent or fire. For this reason, you must have
the work carried out by a qualified workshop.
CD CAUTION
If the car is left standing for Long periods,
protect the battery from frost. The battery
will be damaged irreparably if it is allowed to
freeze <=> page 2 51.
@ For the sake of the environment
'8 Batteries contain toxic substances including
sulphuric acid and Lead. Please contact a
qualified workshop if you have any questions.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
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 reliable starting even after a
Long period <=> page 118. Certain convenience fea­
tures, such as interior Lighting or electric seat ad­
justment, may not be available. These functions Checking
and topping up fluids
will be restored when you switch on the ignition
and start the engine.
Even though some systems are deactivated auto­
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicle is Left standing for Long periods, this
can result in total battery discharge. If the vehi­
cle battery is allowed to discharge completely, an
internal chemical reaction damages the battery
irreparably. To avoid this, the vehicle battery
should be recharged at Least once a month
<=> page 251. Please contact a qualified workshop
if you have any questions.
Winter conditions
Cold weather is very hard on the vehicle battery.
The starting capacity may be reduced as a result.
For this reason, you should have the vehicle bat­
tery checked by a qualified workshop before the
start of winter.

Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" are
specially matched to your Audi. When used prop­
erly, these tyres meet the highest standards in
safety and handling. Your specialist retailer will
be glad to provide more information.
_& WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size
marked on the tyre; with some makes of
tyre the effective tyre size can differ signifi­
cantly from the nominal dimensions, even
though the tyres have the same size desig­
nation. Inadequate tyre clearance can result
in damage to the tyres or the vehicle, caus­
ing a serious safety risk.
-Avoid running the car on tyres that are more
than 6 years old. If you have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
- If wheel trims are fitted after the car is pur­
chased, ensure that there is an adequate
flow of air for cooling the brakes -risk of ac­
cident!

Tyre wear / damage
Fig. 221 Tyre tread: Tread wear indicators
Tyre wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators
¢ Fig.
221 running
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ _8..
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.
