Fig. 82 2-zone deluxe automatic climate control: controls
The functions can be switched on and off by
pressing the buttons or adjusted by turning the
knob. The LED in a button will light up when the
function is switched on.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera-
ture.
AUTO Automatic mode or eco mode*
Automatic mode maintains a constant tempera-
ture inside the vehicle. Air temperature, airflow
and air distribution are controlled automatically.
AUTO mode switches off once a button in the cli-
mate control system is pressed.
Applies to: vehicles with eco mode: Pressing the
AUTO button briefly when automatic mode is ac-
tive will activate the energy-saving mode of the
climate control system. eco will appear on the
control panel display. You can end eco mode by
pressing the AUTO button again.
A/C cooling mode
The cooling mode only functions with the blower
turned on. You can turn the cooling system on or
off by pressing the A/C button. The air is not
cooled and humidity is not removed when cooling
66
mode is switched off. This can cause fog on the
windows. The cooling mode switches off auto-
matically when there are cold outside tempera-
tures.
@ / @ Temperature
The temperature for the driver's and front pas-
senger's side can be adjusted separately with the
dials @/@). Temperatures between 60 °F
(+16 °C) and 84 °F (+28 °C) can be set. If outside
of this range, LO or HI will appear in the climate
control system display. In both settings, the cli-
mate control runs constantly at the maximum
cooling or heating level. The temperature is not
regulated.
Synchronization: Pressing and holding the AUTO
button for two seconds transfers the tempera-
ture setting for the driver to the front passeng-
er's side. This applies a temperature change to
the front passenger's side.
S8 Blower
Using the dial $8, you can manually adjust the
volume of air generated by the blower to your
preference. The blower should always run at a
low setting to prevent the windows from fogging
and to ensure a continuous exchange of air inside
the vehicle. To have the blower regulated auto-
matically, press the AUTO button.

The air distribution can adjusted with the but-
tons. To have the air distribution regulated auto-
matically, press the AUTO button.
The round air vents in the cockpit are adjustable
> page 68.
To keep the front side windows from fogging up
in damp weather, we recommend opening the
side air vents and tilting them to the side.
Foot vents are located under the front seats and
adjustable vents on the end of the center console
to heat the rear of the vehicle.
& Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (22°C) or higher. The temperature is
controlled automatically. In the & setting, the
A/C cooling mode switches on automatically, de-
pending on the outside air temperature.
The AUTO button switches the defroster off.
<> Recirculation mode
The recirculation mode can be turned on manual-
ly or automatically*.
— Switching manual recirculation mode on and
off: press the > button.
— Automatic* recirculation mode: auto recircula-
tion needs to be activated in the Infotainment
system. Select in the Infotainment system:
MENU] button > Vehicle > left control button >
Air conditioning > Auto recirculation. The air
quality sensor that is designed for diesel and
gasoline exhaust automatically switches the re-
circulation mode on or off depending on the
level of pollutants in the outside air.


In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior. Switching recirculation mode on
when driving through a tunnel or when sitting in
traffic is recommended > A.
Pressing the <> button, AUTO or the ® button
switches recirculation mode off.
@ Rear window heating
If the rear window defogger is activated when
the ignition is switched on, the battery manage-
ment determines based on the battery charge if
it is possible to turn on. Otherwise, the rear win-
dow defogger functions with the engine running
and switches off automatically after approxi-
mately 10 - 20 minutes, depending on the out-
side temperature.
To prevent the rear window defogger from
switching off automatically, press and hold the
® button for more than two seconds.
#/ Seat heating*
Pressing the a button switches the seat heating
on at the highest setting (level 3). The LEDs indi-
cate the temperature level. To reduce the tem-
perature, press the button again. To switch the
seat heating off, press the button repeatedly un-
til the LED turns off.
After approximately 10 minutes, the seat heating
automatically switches from level 3 to level 2.

Z\ WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these individuals should
not use seat heating.


@) Note
To reduce the risk of damage to the seat heat-
ing elements, do not kneel on the seats or
place heavy pressure on one area of the seat.
G) Tips
If the front passenger's seat heating is turned
on, it will not turn on again automatically if
more than 10 minutes have passed between

Driving


— Plug-in hybrid drive: never leave the vehicle
unattended in drive ready mode while a gear
is engaged. The vehicle can start moving
(“creeping”) even if the gasoline engine is
switched off, since the electric motor is still
operating. This may cause collisions and se-
vere or fatal injuries. When the vehicle en-
ters drive ready mode, the status message
e-tron READY appears briefly in the instru-
ment cluster display and the needle in the
power meter points to READY > page 16.

@) 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.
G) 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.

Driving

> Select the “P” selector lever position to secure
the vehicle from rolling away.
> Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.
> Switch off the ignition before leaving the vehi-
cle.
On hills, activate the parking brake first and then
shift into the "P" selector lever position. This pre-
vents too much stress from being placed on the
locking mechanism.

ZA WARNING
— Always set the parking brake when leaving
your vehicle, even if for a short period of
time. If the parking brake is not set, the ve-
hicle could roll away, increasing the risk of
an accident.
— Do not leave your vehicle unattended while
the engine is running, because this increases
the risk of an accident.
— If the parking brake is set, it can release au-
tomatically when the accelerator pedal is
pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If you leave the vehicle, switch the ignition
off and take the key with you. This is espe-
cially important when leaving persons or an-
imals in the vehicle. Otherwise, the vehicle
could start unintentionally, the parking
brake could release, or electronic equipment
could activate, which increases the risk of an
accident.
— No persons or animals should be left in a
locked vehicle. Locked doors make it more
difficult for emergency workers to enter the
vehicle, which puts lives at risk.
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal or set the parking brake immediately.

@) Note
If you have to stop on an incline, always press
the brake pedal to hold the vehicle in place to
74
reduce the risk of the vehicle rolling back-
ward. Do not try to hold the vehicle in place
by pressing and holding the accelerator pedal.
The transmission can overheat, which increas-
es the risk of damage.
Hill hold assist
If you take your foot off of the brake pedal when
driving on hills, the braking force will be held for
several seconds. At that time, you can start driv-
ing without the vehicle rolling backward.
Requirement: the driver's door must be closed,
the engine must be on, and the vehicle must be
traveling uphill.
> To activate hill hold assist, press and hold the
brake pedal for several seconds while the vehi-
cle is stationary.

Z\ WARNING
— If you do not begin driving immediately af-
ter releasing the brake pedal, your vehicle
may begin to roll backward. Press the brake
pedal
or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,
on slippery or icy ground).
Messages
Bw Hill hold assist: unavailable

The hill hold assist is temporarily unavailable.
Press the brake pedal to secure the vehicle from
rolling away unintentionally.

The automatic transmission shifts automatically
depending on the selected gear and the current
driving style. When driving with a moderate driv-
ing style, upshifting early and downshifting late
will help to improve fuel economy. When driving
with a sporty driving style, the transmission per-
mits higher RPMs.
The gears are displayed next to the selector lever.
— P (Park): parking lock
—R (Reverse): driving in reverse
—N (Neutral)
— D (Drive): driving forward
Selecting a gear
Requirement: the ignition must be switched on.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the release button (@) on the selector lev-
er.
—To select a gear, move the selector lever into
the corresponding position.
— The label next to the selector lever for the se-
lected gear will light up.
“N” (Neutral) gear
In the “N” gear, power is not transmitted to the
driving wheels. Use the “N” gear in a car wash
(with conveyor belts), for example.
If you unintentionally select “N” while driving
(faster than 1 mph (2 km/h)), you can also shift
back to “D” without pressing the brake pedal.
For safety reasons, the vehicle cannot be locked
when the transmission is in the "N” gear.
“Pp” (Park) gear
The vehicle is secured from rolling away by the
parking lock when in the “P” gear.
If you cannot shift out of “P”, for example be-
cause the vehicle has no power, you may need to
use the emergency release for the parking lock
=> page 88.
Selecting a driving program
Various driving programs can be selected when in
the “D” gear. The programs influence when the
transmission shifts and how the accelerator ped-
al responds.
The selected driving program is displayed in the
instrument cluster.
—D (Drive): normal driving mode
—S (Sport): sporty driving mode
If you select the Dynamic mode in Audi drive se-
lect*, the “S” driving program will be activated.
When the ignition is switched off, the driving pro-
gram may be reset to “D”.
To switch between the current driving program
and “S”, push the selector lever toward the rear.
Plug-in hybrid drive: if you press the while in “S”, the “D” driving program will be se-
lected.

Z\ WARNING
— Before starting to drive, check if the desired
gear is displayed next to the selector lever.
— Always secure your vehicle from rolling
away. Press the brake pedal or shift to “P”.
When leaving the vehicle, also set the park-
ing brake.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except "P" and "N") when
the engine is running.
—To reduce the risk of an accident, do not
press the accelerator pedal when changing
gears if the vehicle is stationary and the en-
gine is running.
