The coolant additive G12++ can be mixed only with additives
G12+ and G12.
Checking coolant level
The coolant level can be checked at a glance.– Switch off the ignition.
– Read off coolant level on radiator expansion tank
⇒fig. 257. When the engine is cold it should be between
the “MIN” and “MAX” marks. When the engine is hot it
may be slightly above the “MAX” mark.The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp in the instrument
cluster ⇒page 33. However, we recommend that it should be
checked occasionally.
Coolant losses
Any loss of coolant normally indicates a leak in the cooling system.
In this case the cooling system should be inspected by a qualified
workshop without delay. It is not sufficient merely to top up the
coolant.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.
Caution
Radiator sealants must not be added to the coolant. Such additives
could seriously impair the function of the cooling system.Topping up the coolant
Be careful when topping up coolant.– Switch off the engine.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 257 with a
cloth, and carefully unscrew the cap anti-clockwise
⇒.
– Add coolant.
– Screw the cap on again tightly.Make sure that the coolant meets the required specifications
⇒page 260, “Coolant”. Do not use a different type of additive if anti-
freeze additive G12++, G12+ or G12 is not available. 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.
Do not fill above the “MAX” mark. Excess coolant is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant has been lost, wait for the engine to cool down
before putting in cold coolant. Failure to do so could result in
serious engine damage.

Wheels and tyres 274For technical reasons snow chains may only be used on tyres with
certain wheel rim/tyre combinations.
Only use snow chains with fine-pitch links. The links must not
protrude more than 13.5 mm from the tyres (including tensioner).
Remove the chains when roads are free of snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
Four-wheel drive: where snow chains are compulsory on certain
roads, this normally also applies to cars with four-wheel drive. Snow
chains may only be fitted to the front wheels (also on vehicles with
four-wheel drive).Run flat tyresApplies to vehicles: with run flat tyresIntroduction
Run flat tyres allow you to continue your journey in the
event of a loss of tyre pressure.Run flat tyres have reinforced sidewalls which support the tyre in
the event of a loss of pressure.
Run flat tyres must only be used on vehicles which were already
factory-fitted with these tyres and which also have a tyre pressure
monitoring system*.
Run flat tyres can be identified by the marking “RSC” (Runflat
System Component) on the sidewall.If you change the tyres on your vehicle from regular tyres to run flat
tyres or vice-versa, the control unit must be reprogrammed by an
Audi dealer or other qualified workshop.
What are the benefits of run flat tyres?
Run flat tyres ensure that you remain mobile, even in the event of a
loss of tyre pressure. In favourable conditions these tyres have an
operating range of at least 30 km, however the vehicle must not be
driven faster than 80 km/h ⇒ in “Driving with run flat tyres” on
page 275.
The tyre pressures are constantly checked by the tyre pressure
monitoring system. When the run flat system becomes active
(centre display), it is still the driver's responsibility to check the
tyre(s) affected and to decide whether it is possible to continue
driving. Also refer to ⇒page 275, “Driving with run flat tyres”.
When is it no longer possible to continue driving with
the help of the run flat tyres?
•
If the Electronic Stabilisation Program (ESP) is out of operation
or is triggered continuously.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc.
If a tyre has been badly damaged there is a risk that parts of the
tread can be thrown off and cause damage to the fuel lines, brake
pipes or fuel filler.
•
You must stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
•
You must also stop driving if damage to the tyres (e.g. tears in
the sidewalls) becomes apparent.
WARNING
Please ask your Audi dealer or qualified workshop whether run flat
tyres can be used on your vehicle. Unauthorised use of these tyres
can invalidate the vehicle's type approval for use on public roads.

Fuses and bulbs 304BulbsChanging bulbs
Changing bulbs requires a certain degree of practical
skill.You can change the following bulbs for exterior lights yourself:•
Halogen headlights: Bulb for dipped headlights
•
Halogen headlights: Bulb for main beam headlights
•
Bulb for fog light
•
Bulbs for rear lights in boot lid
•
Bulbs for rear lights in side panel
•
Bulbs for number plate light
The following bulbs should only be changed by a qualified work-
shop:
•
Halogen headlights: Bulb for turn signals
•
Halogen headlights: Bulb for side lights
•
Xenon headlights*: Bulb for turn signals
•
Xenon headlights*: Light source for daytime running
lights/parking lights
•
Bulb for headlights: Bi-xenon lights ⇒
•
Light source for turn signal in exterior mirror housing
•
Light source for high-level brake light
As a rule, you require a certain degree of practical skill to change
defective bulbs. This applies in particular to those bulbs which are
only accessible from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed
by a qualified workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment your-
self, be aware of the safety risks involved ⇒page 255 ⇒.
Types of bulbs
You must only replace a bulb with a bulb of the same type. Informa-
tion regarding e.g. the wattage can be found on the base of the
bulb.
