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.

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
the approved type of additive is not availa­

ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

Checking coolant level

•
Park the vehicle on a level surface.

•
Switch off the ignition.

•
Read off the coolant level on the coolant ex­
pansion tank
^>Fig.
248. When the engine is

cold,
the coolant level should be between the
marks. When the engine is warm, it may be
slightly above the top mark.
Topping up coolant
Important: The coolant expansion tank must not
be empty
•=>([).

•
Wait for the engine to cool down.

•
Cover the cap on the expansion tank with a

cloth,
and carefully unscrew the cap
anti-clock­

wise
<=>
/K.

*-
Add coolant in the correct concentration

tapage
299 up to the top mark.

•
You should make sure that the fluid level re­
mains stable. If necessary, add more coolant.

•
Screw the cap on again tightly.
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.

- 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!

Wheels

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.

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
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
•=> /\.
•
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
<=> /\.

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
document1)).

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.
Applies to vehicles with four-wheel drive: All four
wheels must always be fitted with tyres of the
same type, make and tread pattern, as the drive-
line could otherwise be damaged by variations in
the wheel speeds. For the same reason, only use
a spare wheel* which has the same rolling cir­
cumference 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): •
