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.

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!

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.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if

and topping up fluids
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.

brake fluid level
� Read off the brake fluid level on the brake fluid
reservoir ¢page 246, Fig. 214. The brake fluid
level must be between the MIN and MAX marks
¢_A.
The brake fluid level is also automatically moni­
tored.
Having brake fluid changed
Have the brake fluid changed regularly by a quali­
fied workshop.
A WARNING
- If the brake fluid level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired -risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
CD CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on
the reservoir in certain circumstances and
cause damage to the vehicle.
- Brake fluid must not be allowed to come in­
to contact with the vehicle&#39;s body, other­
wise it will attack the paintwork.
Battery General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by a qualified
workshop ¢ ,& .
The term &#34;vehicle battery&#34; refers to the 12 Volt
battery in your vehicle.

Wheels
Tyres and rims
General notes
� Inspect the tyres regularly for damage (cuts,
cracks or blisters, etc.). Remove any foreign
bodies embedded in the treads.
� If you have to drive over a kerb or similar obsta­
cle, drive very slowly and as near as possible at
a right angle to the kerb.
� Damaged rims or tyres must be replaced imme­
diately.
� Keep grease, oil and fuel off the tyres.
� Mark
the wheels before taking them off so that
they rotate in the same direction when refitted.
� When removed, the wheels should be stored
flat in a cool, dry and preferably dark place.
CD CAUTION
- Please note that summer and winter tyres
are optimised for the prevailing road condi­
tions at different times of year. We recom­
mend that you use winter tyres during the
winter months. At low temperatures, sum­
mer tyres lose their elasticity and grip, and
braking performance also suffers as a re­
sult. Cracks can form in the tread block on
summer tyres if they are used at very cold
temperatures, and this can cause perma­
nent damage to the tyres. An increase in
rolling noise and tyre imbalance may result
from this damage.
- Machined, polished or chrome-plated rims
must not be used in winter conditions. The
process used to manufacture these types of
wheel rim does not provide adequate sur­
face protection against corrosion, and the
rims can be permanently damaged by road
salt or similar.
New wheels or tyres
It is best to have all servicing of wheels and tyres
performed by a qualified workshop, since they
l l
COC = Certificate of conformity
254 have
the necessary special tools and replacement
parts in addition to trained personnel.
� New tyres do not yet give maximum grip. When
driving with new tyres, drive at moderate
speeds and be especially careful during the first
500 km.
� All four wheels must be fitted with tyres of the
same type, size (rolling circumference) and
preferably the same tread pattern.
� Tyres should be replaced in pairs and not indi­
vidually (i.e. both front tyres or both rear tyres
together).
� We recommend the use of Audi Genuine Tyres.
If you wish to use other tyres, please note that
the actual size can differ from the nominal size
marked on the tyre ¢ A .
� If you wish to purchase a different combination
of rims and tyres than the ones fitted on the ve­
hicle during production, it is advisable to con­
sult a qualified workshop beforehand ¢ A.
The sizes of the rims and tyres approved for your
vehicle are listed in the vehicle&#39;s documents (e.g.
EC Certificate of Conformity or COC document l)).
The vehicle documents vary depending on the
country in which the vehicle is registered.
If the spare wheel* is not the same type as the
tyres fitted on the car (for example if the car has
winter tyres or wide-section tyres) you should on­
ly use the spare wheel* if a puncture occurs, and
then only for a short period of time. In this case,
please drive with extra care. Refit a normal road
wheel as soon as possible.
On vehicles with four-wheel drive, all four wheels
must always be fitted with tyres of the same
type, make and tread pattern, as the driveline
could otherwise be damaged by variations in the
wheel speeds. For the same reason, only use a
spare wheel* which has the same rolling circum­
ference as the normal road wheels.
Manufacturing date
The manufacturing date is indicated on the tyre
sidewall (possibly only on the inner side of the
wheel): ..,.

a tyre puncture is not possible with the seal­
ing compound.
{D Note
Do not use the compressor for longer than
6 minutes at a time, as it could overheat.
When the compressor has cooled down, you
can use it again.
After repairing a tyre
Applies to: vehicles with tyre repair kit

ded in the tyre repair kit, to the dashboard
where the driver will see it.
.,. 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.
A WARNING
After repairing a tyre please note the follow­
ing points:
- Do not drive faster than 80 km/h.
-Avoid heavy acceleration, hard braking and
fast cornering.
- Vehicle handling could be impaired.
- If the tyre is too badly damaged, you should
seek professional assistance.

Tow-starting / towing
away
General notes
Some experience is required to tow or tow-start a
vehicle, especially when using a tow-rope. Both
drivers should be familiar with the technique re­
quired for towing. Inexperienced drivers should
not attempt to tow-start or tow away another ve­
hicle.
Do not pull too hard with the towing vehicle and
take care to avoid jerking the tow-rope. When
towing off-road, there is always a risk that the
anchorage points may be overloaded.
Tow-bar I tow-rope
It is easier and safer to tow the vehicle with a
tow-bar. You should only use a tow-rope if you do
not have a tow-bar. It is advisable to use a tow­
rope made of elastic synthetic fibre or similarly
elastic material.
