Checking and Filling

Checking the engine oil level
The engine oil level can be checked in the MMI.
Observe the safety precautions > page 259, Gen-
eral information.
>» Park the vehicle on a level surface.
> Shut the engine off when it is warm.
> Switch only the ignition back on.
> Wait approximately two minutes.
> Applies to MMI: Select on the home screen: VE-
HICLE > Settings & Service > Oil level.
> Read the oil level in the display. Add engine oil
if the bar in the oil level indicator is just below
“min” > page 264.
@) Note
If the engine oil level is too low or too high,
there is a risk of engine damage.
@) Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in-
strument cluster. Add oil and close the hood.
The current oil level will be displayed on the
MMI the next time the ignition is switched on.
@) Tips
The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km), de-
pending on driving style and operating condi-
tions. In RS models, the oil consumption may
be up to 1 qt/600 mi (0.8 L/1,000 km). Con-
sumption may be higher during the first
3,000 miles (5,000 km). The engine oil level
must be checked regularly. It is best to check
each time you refuel your vehicle and before
long drives.
— Because of the lubrication and cooling of
the engine, combustion engines consume
oil. The oil consumption varies depending
on the engine and may change during the
service life of the engine. Engines generally
consume more oil at the beginning during
the break-in period. Then oil consumption
stabilizes after the break-in period.
264
— Under normal conditions, oil consumption
depends on the quality and viscosity of the
oil, the engine RPM, the climate conditions,
and the road conditions. The dilution of oil
from condensation or fuel residue as well as
the age of the oil also play a role. Because
engine wear increases with mileage, oil con-
sumption will increase again over time until
it may be necessary to replace worn compo-
nents.
Because all these variables play a role, it is
not possible to define an oil consumption
standard. Therefore, the oil level must be
checked regularly.
If you believe that your engine has in-
creased its oil consumption, contact an au-
thorized Audi dealer or authorized Audi
Service Facility to determine the cause.
Please note that an exact oil consumption
measurement must be done with the neces-
sary care and accuracy and may take time.
An authorized Audi dealer or authorized
Audi Service Facility is trained in accurately
measuring the oil consumption.

Observe the safety precautions > page 259, Gen-
eral information.

Checking and Filling


— 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.
— Drain the oil into a container designed for
this purpose that is large enough to hold the
full amount of oil in your engine.
— Engine oil is poisonous. Always store out of
reach of children.
— Prolonged contact of used engine oil with
the skin may cause skin damage. Always
wash oil off immediately with soap and wa-
ter to protect your skin.
@) Note
Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited War-
ranty.

@ For the sake of the environment
— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed.
The coolant level is monitored using the g indi-
cator light. However, occasionally checking the
coolant level is recommended.
Messages
& Turn off engine and check coolant level. See
owner's manual

The coolant level is too low.
Stop driving and switch the engine off. Check the
coolant level > page 267.
— If the coolant level is too low, add coolant
=> page 267. Only continue driving once the in-
dicator light turns off.
|_| Coolant temperature: too high. Please let
engine run while vehicle is stationary
Let the engine run at idle for a few minutes to
cool off, until the indicator light turns off.
— If the indicator light does not turn off, do not
continue driving the vehicle. See an authorized
Audi dealer or authorized Audi Service Facility

Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only add the follow-
ing coolant additives mixed with distilled water.

Coolant additive Specification

G12evo TL774L

The amount of coolant 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 engine.
