open hood AUDI TT 2021 Owner´s Manual

Checking and Filling

> Applies to: using engine oil that meets the rec-
ommended specification: Add some more
engine oil again if necessary.
> Close the engine oil filler cap and push the dip-
stick
all the way in.
> Close the hood > page 202.

ZX WARNING
— When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of a fire.
— You must close the cap on the oil filler open-
ing correctly so that oil does not leak out on-
to the hot engine and exhaust system when
the engine is running, because this is a fire
hazard.
— Always clean skin thoroughly if it comes into
contact with engine oil.
—
Engine oil is poisonous and must be kept out
of reach of children.
— Store the engine oil securely in the original
container.

@) Note
— The New Vehicle Limited Warranty does not
cover damage or malfunctions if the recom-
mended intended use of the vehicle and
maintenance measures listed in the Audi
Owner's Manual and the Warranty & Main-
tenance Booklet were not followed.
— Only use high-grade engine oil that explicit-
ly meets the Audi oil quality standard for
your vehicle. Using another oil may cause
severe vehicle damage.
— Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited
Warranty.
@ For the sake of the environment
— Oil should never enter the sewer system or
come into contact with the ground.
— Follow the legal regulations in the country
where you are located when disposing of
empty oil containers.

Changing engine oil
Audi recommends having the oil changed at an
authorized Audi dealer or authorized Audi Serv-
ice Facility.
Observe the safety precautions > page 200, Gen-
eral information.
The engine oil must be changed at the intervals
specified in the Warranty & Maintenance Book-
let. This is very important because the lubrication
function of the oil gradually declines during regu-
lar vehicle operation.
The engine oil should be changed more frequent-
ly under certain circumstances. Have the oil
changed more frequently if you often drive short
distances, your vehicle is predominantly in stop-
and-go traffic situations, is in very dusty environ-
ments, or is operated for long periods of time in
temperatures below zero.
Cleansing additives in the oil make fresh oil ap-
pear darker after the engine has run briefly. This
is normal and no reason to change the engine oil
more frequently than recommended.
Because correctly disposing of engine oil is diffi-
cult and special tools and technical knowledge
are needed for an oil change, Audi recommends
having your engine oil changed by an authorized
Audi dealer or authorized Audi Service Facility.
If you change the engine oil yourself, please note
the following important information:

ZA\ WARNING
If you change the engine oil on the vehicle
yourself, the following precautions must be
followed:
— Wear protective eyewear.
— Due to the risk of scalding, allow the engine
to cool down sufficiently.
— Maintain enough distance when you are re-
moving the oil drain plug. While doing this,
keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm. >

Checking and Filling

— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
— You can continue driving if the permitted
G12evo coolant additive was not added.
However, go to an authorized Audi dealer or
authorized Audi Service Facility immediately
to have the coolant replaced to reduce the
risk of engine damage.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide
you with important information about
the recommended coolant additive.

eral information.
Checking the coolant level
>» Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 202.
> Check the coolant level in the coolant expan-
sion tank > page 203, fig. 168 using the outer
markings @) > fig. 177. The coolant level must
be between the markings 2) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@).
208
If you must add coolant, use a mixture of water
and coolant additive. Audi recommends mixing
the coolant additive with distilled water.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Remove the cover (1) > fig. 777 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 207 up to the upper marking @)
> fig. 177.
» Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately 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, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

Z\ WARNING
— The motor compartment in any vehicle is a
potentially dangerous area. Stop the engine
and allow it to cool before working in the
engine compartment. Always follow the in-
formation found in > page 200, General in-
formation.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— 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.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
