Emissions control
system
General information
Z\ WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
— Never touch the exhaust tail pipes once they
have
become hot. This could result in burns.
— Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the emissions sys-
tem could start a fire.
— Do not apply underbody protectant in the
exhaust system area, because this increases
the risk of fire.
Catalytic converter
Follow the safety precautions > page 227, Gener-
al information.


The vehicle may only be driven with unleaded
gasoline, or the catalytic converter will be de-
stroyed.
Never drive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel
could enter the exhaust system, which could
cause overheating and damage to the catalytic
converter.
Malfunction Indicator Lamp (MIL)
If the S indicator light blinks or turns on, there
is a malfunction that is causing poor emissions
quality and that could damage the catalytic con-
verter. Drive slowly to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction corrected.
Engine compartment
General information
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in-
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precautions provided in the following in-
formation. The engine compartment is a dan-
gerous area in the vehicle. > A\.

ZA\ WARNING
—Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the engine com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns

Checking and Filling

@) 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. Consumption 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.
— 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.
232
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.
— You can find information on engine oil and
engine oil capacities for the USA at www.

ada at www.audi.ca/ca/web/en/

of a fire. >

Checking and Filling

@ 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 B indi-
cator light. However, occasionally checking the
coolant level manually 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 235.
— If the coolant level is too low, add coolant
=> page 235. Only continue driving once the in-
dicator light turns off.
Ba Coolant temperature: too high. 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
for assistance.
| Coolant system: malfunction! Please turn
off engine
Do not continue driving, shut the engine off, and
switch the ignition off.

— See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow-
ing coolant additives. These additives may be
mixed with each other.


Coolant additive Specification
Gl12evo TL774L
G12++ TL774G
G13 TL774J

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.



Coolant Freeze protec-
additive tion
Warm min. 40% min. -13 °F
regions max. 45% (-25°O
Cold min. 50% max. -40 °F
regions max. 55% (-40 °C)

@) Note
— Before winter weather begins, have an au-
thorized Audi dealer or authorized Audi
Service Facility check if the coolant additive
in your vehicle matches the percentage ap-
propriate 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.
— 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 >

wiper on the front passenger's side toward the
windshield and remove the cover.
> Check the coolant level in the coolant expan-
sion tank > page 230, fig. 147 using the outer
markings @) > fig. 149. The coolant level must
be between the markings @) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
> If you add coolant to the coolant expansion
tank for the combustion engine, see
=> page 234, Cooling system.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@).

feel resistance a second time.
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.

ZA\ WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 227, General informa-
tion.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
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 engine
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.

C) Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and >
