Seats


Z\ WARNING
Only remove the rear seat head restraints
when necessary in order to install a child safe-
ty seat > page 278, Child safety. Install the
head restraint again immediately once the
child safety seat is removed. Driving with the
head restraints removed or not in the upright
position increases the risk of serious injury.


Steering wheel
General information
Make sure that:
— The distance between your upper body and the
steering wheel is at least 10 in (25 cm)
— Your arms are bent slightly at the elbows
— You have a sufficient view of the area around
the vehicle and you have a clear view of the in-
strument cluster
— You are always holding the steering wheel with
both hands on the outer edge at the sides (9:00
and 3:00 position) when driving

Z\ WARNING
—To reduce the risk of an accident, make sure
the steering wheel is adjusted correctly and
cannot be moved out of position before you
start to drive.
— If you are too close to the steering wheel,
the driver's airbag cannot provide optimal
protection, which increases the risk of injury
or fatality.
— Never hold the steering wheel in the 12:00
position or in any other way, such as holding
the center of the steering wheel. Otherwise,
your arms, hands, and head could be injured
in the event that the driver's airbag deploys.
— If your physical characteristics prevent you
from sitting at least 10 inches (25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters
that will help.

Climate control system
Your vehicle has a deluxe automatic climate con-
trol system with two zones where the tempera-
ture, air distribution, and amount of air can be
adjusted separately on the left and right front
sides.
The climate control system circulates, warms or
cools, and removes humidity from the air in the
vehicle interior. It is the most effective when the
windows and panoramic glass roof* or power
top* are closed. If there is a build-up of heat in-
side the vehicle, ventilation can help to speed up
the cooling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Presets
Several functions can be preset in the Infotain-
ment system.

ty.


ZA WARNING
Poor visibility can lead to accidents.
— For safer driving, keep all windows free of
ice, snow and fog.
— Become familiar with the correct use and
function of the climate control system as
quickly as possible, especially with the de-
frosting and defogging functions.
— When the temperature is below freezing,
only use the windshield washer system after
the
windshield has been warmed by the cli-

mate control system. The washer fluid could

() Note
— If you suspect that the climate control sys-
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
— Repairs to the Audi climate control system
require special technical knowledge and
special
tools. See an authorized Audi dealer
or authorized Audi Service Facility.
@) For the sake of the environment
— Energy can be saved by switching off the A/C
mode.
— In vehicles with the efficiency program”, you
can find other consumption information and
more economy tips > page 23.
iG) Tips
—To prevent interference with the heating
and cooling output and to prevent the win-
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow, and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.
— The climate control settings are automati-
cally stored and assigned to the vehicle key
that is in use. These settings are different
when the power top* is open or closed.

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.

Driving

Switching the ignition on or off
If you would like to switch the ignition on or off
without starting the engine, follow these steps:
> Switching on: turn the key to position @.
> Switching off: turn the key to position ©).

ZA WARNING
—To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as
usual may increase the risk of accidents and
serious
injuries.
— Never remove the ignition key from the igni-
tion lock while the vehicle is moving. Other-
wise, the steering lock could engage and you
would not be able to steer the vehicle, which
increases the risk of an accident.

@) Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You
could damage the engine.
— If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off and there is a risk of damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.
