Checking and Filling
and use common sense. Never risk personal
injury.
– 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
– Never perform any work in the engine com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
– If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from work that is not
performed correctly.
– To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
– Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
– Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
– If a position is selected while the vehicle is
stationary 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.
WARNING
– Turn off the engine.
– Turn off the ignition.
– Set the parking brake.
– Select the “P” (Park) position.
– Allow the engine to cool.
– Keep children away from the engine com-
partment.
– 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.
– Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
– Set the parking brake first and select the
“P” (Park) position.
– 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 turned
off.
– Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
– Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
– 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.
