Engine Cooling System - Audi TT 2012 Owner's Manual

lBB Checking and filling
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly.
CD
Note
- The oillevel must not be above range
CV
- danger of converter or engine damage!
Contact an authorized dealership to draw
off oil, if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@J
For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow Legal regulations
when disposing of empty oil containers.
Changing the engine oil
We
recommend that have your oil changed by
an authorized Audi dealer or a qualified serv-
ice station.
Before you check anything in the engine com-
partment, always read and heed aIL WARN-

ment on page

The engine oil must be changed according to
the intervals specified in your Warranty &
Maintenance booklet. This is very important
because the lubricating properties of oil di-
minish gradually during normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly short dis-
tances, operate the vehicle in dusty areas or
under predominantly stop-a nd-go traffic con-
ditions, or have your vehicle where tempera-
tures remain below freezing for extended pe-
riods.
Detergent additives in the oil will make fresh
oillook dark after the engine has been run-
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex-
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choose to change your oil yourself,
please note the following important informa-
tion:
A
WARNING
To reduce the risk of personal injury ifyou
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run-
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
ofthe reach of children.
- Continuous contact-with used engine oil
is harmful to your skin. Âlways protect
your skin by washing oil offthoroughly
with soap and water.
CD
Note
Never mix oil additives with your engine
oil. These additives can damage your en-
gine and adversely affect your Audi Limit-
ed New Vehicle Warranty.
@
For the sake of the environ ment
- Before changing your oil, first make sure
you know where you can properly dispose
ofthe used oil.
- Always dispose of used engine oil proper-
~
ly. Do not dump it on garden soil,
--
w ooded 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 service station.
Engine cooLing system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro-
tects the engine from freezing in the winter.
The cooling system is sealed and generally re-
quires little attention.
The cooling system has been filled at the fac-
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly-
col-basedcoolant additive G12++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mix-
ture bath assures the necessary frost protec-
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. Tt also raises the boiling point ofthe
coolant.
Do not reduce the concentration of the cool-
ant in the summer by adding plain water. The
proportion of coolant additive must be at
least 50% but not more than 60% to main-
tain antifreeze protection and cooling efficien-
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi-
cle heating and engine cooling system.
For year-round driving, antifreeze is added at
the factory for temperatures down to:
--31 0 F(-35°C)U5A
- - 40 OF (- 40 oC) Canada.
Yo u can mix the G12++ coolant additive with
other additives (G12+ or G12). Always check
With your authorized Audi dealer.

Note
- Before winter sets in, have the coolant
checked ta see if the coolant additive in
your vehicle is sufficient to meet the cli-
mate conditions. This is especially impor-
tant ifyou live in a region where the win-
ter is extremely cold. If necessary, in-
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
'cooling system, remember:
- We recommend using only coolant ad-
ditive G12++ (check the label) for your
vehicle. This coolant additive is availa-
ble at authorized Audi dealers. Other
types of antifreeze can significantly re-
duce corrosion protection. The result-
ing corrosion can cause a loss of cool-
ant and serious engine damage.
- Do not add any type of radiator leak seal-
ant ta your vehicle's engine coolant.
Adding radiator repair fluid may adverse-
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
