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.

250 Checking
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'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 "vehicle battery" 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'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): ..,.

- If it was not possible to build up a tyre pres
sure 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 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
.,. Affix the sticker "max. 80 km/h", which is inclu
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.
