Setting the charging power level
Applies to: vehicles with plug-in hybrid drive
The control unit automatically recognizes the
voltage and the available current strength. You
can set whether you would like to charge with full
or reduced charging power. The last setting that
was selected will be saved and used again the
next time the vehicle is charged. If multiple
items are connected to the power circuit, the
charging current may be reduced when charging
at a power outlet. This can help to prevent the
electrical equipment from overheating.
Before charging, always check if the charging
power setting that was selected last is still suita-
ble.

Emissions control
system
(ee eileen)
ZX 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.
(el e-] Nad (mcl akg
Follow the safety precautions > page 303, 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.
On Board Diagnostic System (OBD)
The On Board Diagnostic System monitors the
engine and transmission components that influ-
ence emissions.

Checking and Filling

> Check the coolant level in the coolant expan-
sion tank > page 307, fig. 248 using the outer
markings (2) > fig. 252. The coolant level must
be between the markings (2) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
Adding coolant
Applies to: vehicles with plug-in hybrid drive:
Your vehicle has two coolant expansion tanks
that are separate from each other. The smaller of
the two expansion tanks must not be opened
= page 312. Read and follow the important safe-
ty precautions > A\ in Coolant on page 312.
Requirement: there must be a residual amount of
coolant in the expansion tank >@).
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cover.
> Remove the cover (@) © fig. 252 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 311 up to the upper marking @
> fig. 252.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
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.

— 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.

@) Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.
