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 230, 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.
The indicator light can also turn on if the fuel fill-
er cap is not closed correctly > page 228).
Engine compartment
(er eel lacela)
Special care is required if you are working in the
engine compartment
When performing work in the engine compart-
ment, such as checking and filling fluids, there
is a risk of injury, scalding, accidents, and
burns. For this reason, follow all the warnings
and general safety precautions provided in the
following information. The engine compart-
ment is a dangerous area in the vehicle. > A\.

) Depending on the engine and country

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 contain
in the coolant) can catch fire.
ed
— 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 coolan
escaping.
tis
— 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
—To protect your face, hands, and arms fro m
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under an
circumstances. This increases the risk of
burns.
y
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition syste
when the engine is running or is starting.
m
— Ifa gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.

Stop driving and switch the engine off. Check the
coolant level > page 239.
— If the coolant level is too low, add coolant
=> page 239. Only continue driving once the in-
dicator light turns off.
Ba Coolant temperature: too high. Please let

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)

in your vehicle matches the percentage ap-
propriate for the climate. This is especially
important when driving in colder climates.

store the correct mixture ratio with the
specified coolant additive as soon as possi-
ble.
