Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory. This coolant must not be not changed.
The coolant leve l is monitored through the. in­
d icator light~
page 26. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents. Only use the fo llow­
ing coolant add it ives. These additives may be
mixed w ith each other.

The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the eng ine.

- Befo re the start of winter, have an author­
i zed Audi dealer or authorized A udi Se rvice
Fac ility check if the coolant additive in your
328
vehicle matches the per cen tage appropriate
for the climate . This is especially important
when driving in colder climates.
- If the appro priate coo la nt additive is not
availab le in an eme rgency, do not add any
ot her additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant add itive as soo n as poss i­
ble.
- Only ref ill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant.

.,. Read the coolant level on the coolant expansion
tank
~ fig. 269.
.,. Th e coolan t level must be between the MIN and
MAX marki ngs when the engine in co ld. When
the engi ne is warm it can be sligh tly above the
MAX marking .
Adding coolant
Requirement: there must be a residua l amount of
coolan t in the expansion t ank

¢page 328 up to the MAX marking .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car wh ich you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and long term damage from water that can enter
housings that have not been properly resea led.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Gas discharge lamps (Xenon lights):
Fuses and bulbs
Due to the high e lectrica l voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker.
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
& WARNING ~ -
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On veh icles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h igh-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the bulb holders that can cause serious cuts. If
you are uncerta in about what to do, have
the work performed by an authorized Audi deale r or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be awa re that the engine compa rt­
ment is a hazardous area to work in~.&..
in
Working in the engine compartment on
page 322.
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
