OA erating manual.

Hot motor components!
Rotating parts!

The radiator fan can switch on at any
time!

High voltage! The voltage in the high-
voltage system is high enough to cause
fatal injuries. Touching a damaged high-
voltage component can result in a fatal
electric shock.



— The coolant expansion tank cap is equipped
with a seal that must never be removed un-
der any circumstances > page 236. If the
coolant expansion tank is not sealed, con-
tact an authorized Audi dealer or authorized
Audi Service Facility.
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure.
—To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.

only be opened by an authorized Audi dealer

ZA WARNING
The voltage in the high-voltage system is high
enough to cause fatal injuries. Touching a
damaged high-voltage component can result
in a fatal electric shock. The components in
the high-voltage system are marked with a
warning label which warns of the high-volt-
age.
— The voltage level in the high-voltage system
is still dangerous and potentially life-threat-
ening when the ignition is switched off.
— Never perform work on orange high-voltage
cables or on high-voltage components. Only
authorized repair facilities that are certified
may perform work on the high-voltage sys-
tem.

the ignition off and allow the cooling system
to cool down. Always follow the information
found in > page 233, General information.
— 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.
— The coolant expansion tank may only be
opened and filled by an authorized Audi
dealer or authorized Audi Service Facility.
— The coolant expansion tank cap is equipped
with a seal that must never be removed un-
der any circumstances > page 236. If the
