Steering wheel heating
Scale Rie mola
Applies to: vehicles with steering wheel heating
> Press the @ button on the multifunction steer-
ing wheel to switch the steering wheel heating
on and off.
G@) Tips
The steering wheel heating settings are stor-
ed automatically and assigned to the vehicle
key that is in use.
Messages
Applies to: vehicles with steering wheel heating
@ Steering wheel heating: on / Steering wheel
heating: off
This message appears if you switched the steer-
ing wheel heating on or off by pressing the @
button on the multifunction steering wheel.

Steering wheel heating: malfunction! See own-
er's manual
If this message appears, there is a malfunction.
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction repaired.
Auxiliary climate control
Applies to: vehicles with auxiliary climate control
The auxiliary climate control system warms or
cools the vehicle interior. The vehicle will turn on
the auxiliary climate control system if needed,
depending on the last temperature that was set
with the climate control system controls. This
function can be used when the drive system is
switched off.
You can turn the auxiliary climate control system
on and off immediately in the Infotainment sys-
tem or set a timer.
Requirement: the high-voltage battery must have
a sufficient charge level and there must be
enough fuel in the tank.
@) Tips
— The temperature that the climate control
system adjusts to depends on the last tem-
perature you set in the climate control unit.
— Using the auxiliary climate control while
charging can also reduce the charge level of
the high-voltage battery.
— The auxiliary climate control system will not
turn on automatically or will turn off earlier
if the high-voltage battery charge or fuel
supply are too low, even if the vehicle is be-
ing charged at the time.
— Starting or stopping the vehicle will not
switch off the auxiliary climate control auto-
matically.

Error messages
(ZA - The high-voltage battery charge level is too
low to heat/air condition the vehicle using only
electric power. Vehicles with auxiliary heating/air
conditioning* can continue to be heated or
cooled using the fuel in the tank.
If one of the following symbols appears in the
display, then you cannot switch on the auxiliary
climate control system or auxiliary heating/air
conditioning*:
2— - There is a system malfunction.
A - The fuel level is too low.
@) Tips
— If you switch the ignition off, the timer set-
tings will appear in the Infotainment sys-
tem display. You can still adjust the settings
for several minutes. The climate control sys-
tem can be started immediately, which will
maintain the desired climate control condi-
tions while you are not in the vehicle.
— You can set the timer a maximum of seven
days in advance.
— You can operate the climate control in the
vehicle interior when the high-voltage bat-
tery is charging using the charging timer
= page 106. The target climate control out-
put depends on the power supply capacity.
— Make sure the time and date match in the
Infotainment system settings so that the
timer can function correctly > page 230.
— The auxiliary climate control can continue to
run after the departure time is reached.

> Set the departure time, the date or day of the
week.
> You can specify a preferred charging time with
the charging timer, for example if you would
like to use the off-peak rate.
> You can activate the auxiliary air conditioning

@ Tips
— Auxiliary climate control is powered electri-
cally if you select climate control using the
charging timer. This may also be used in
confined spaces such as garages.
— Using the auxiliary climate control while
charging can also reduce the charge level of
the high-voltage battery.
—The charging process can be interrupted at
any time. Press the active button on the ve-
hicle to do this > page 105, fig. 105.
— The climate control output while charging
depends on the capacity of the electrical
connection. Additional information on cli-
mate control can be found under > page 68.

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.
> To set the charging power level, press and hold
the @ button @ > page 105, fig. 104 for at
least two seconds.
After the charging power level is set, the status
LEDs ©, iand {) will flash green one time. The
selected value (50% or 100%) is displayed on the
left or right side of the ® button.
Name lee ale]
Applies to: vehicles with plug-in hybrid drive
After
completing the charging or climate control
process, the vehicle enters a sleep mode. No dis-
plays are visible on the charging unit during this
period. Always remove the vehicle charging con-
nector first after charging.
The vehicle charging connector is locked during
and after charging. You must unlock the connec-
tor to remove it.
Unlocking the vehicle charging connector
when the vehicle is locked
> Unlock the vehicle. The connector will unlock
for 30 seconds.
> Remove the connector.
> If the connector is not removed within 30 sec-
onds, it will lock again automatically.

Checking and Filling

Battery
eae mee eles)
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A\.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 315, Lead
battery or > page 316, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 316, Other bat-
tery types
— Applies to: plug-in hybrid drive: High-voltage
battery (for example, for electric driving)
=> page 96.
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be reduced or switched off
=> page 82. Some convenience functions, such as
interior lighting or power seat adjustment, may
not be available under certain circumstances.
These convenience functions will be available
again once you switch the ignition on and start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 316. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places higher demands on the bat-
tery. This results in reduced starting ability. Have
the battery checked by an authorized Audi dealer
or authorized Audi Service Facility before cold
weather begins.

ZA WARNING
— 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.
— Never connect the charging cable or jump
start cable directly to your vehicle battery.
Only use the connections in the engine com-
partment > page 316.

Z\ WARNING
California Proposition 65 Warning:
— Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling.


@) Note
If the vehicle will be parked for long periods
of time, protect the battery against the cold
so that it will not be destroyed by “freezing”
= page 316, Charging the battery.
