@ For the sake of the environment
-Before changing your oil, first make sure
you know where yo u can properly dispose of
the used oil.
- Always dispose of used engine oil prope rly .
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used engine oil collection facility in your area, or
contact a serv ice stat ion.
Cooling system
Coolant
The engine coo ling system is filled with a mixture
of purified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant leve l is monitored through
the . in­
d icator
light ¢ page 28. However, we do recom­
mend occasionally checking the coo lant level
manually.
I f you m ust add coolant, use a m ixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant addi tive is made of anti-freezing and
cor ros ion pro tection agents. Only use the follow­
ing coolant additives . These additives may be
mixed with each other.
Coolant additive Specification
G13 TL 774 J
G12++ TL 774 G
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 coolan t can freeze
and damage the engine.

(D Note
-
Before the start of winter, have an a uthor ­
ized Aud i dea ler o r authorized Audi Serv ice
Facility check if the coo lant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coo lant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine . If this happens, on ly use water and re­
store the correct mix tu re ratio with the
specified coolant add it ive as soon as poss i­
ble.
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .

Checking and Filling
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive* : Your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 104. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 105 .
Requirement: there must be a residual amount of
coolant in the expansion tank
¢ (D .
~ Let the engine cool down.
~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Audi 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.
.,&. WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components.
324
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- 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 ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving . See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­
ble .
- Only refill with new coolant.
- Radiator sealant must not be mixed with the coolant.
· Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes
-even
with the ignition off.
It can even switch on again
later by
itself ¢.& , if .,..

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
cu lt 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 which you can only reach
through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apa rt and then properly put back
together to help prevent breakage of parts and
