ZA WARNING
Curved mirror surfaces (for example convex)
enlarge the field of vision. However, they
make objects in the mirror appear smaller and
farther away. When using these mirrors to es-
timate your distance to vehicles behind you
when changing lanes, you could estimate in-
correctly, which increases the risk of an acci-
dent.

@) Note
— Applies to: vehicles with power folding exte-
rior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow-
er folding function to fold the mirror all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous-
ing must not be moved back into place by
hand because this could impair the function
of the mirror mechanism.
— Applies to: vehicles without power folding
exterior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in place by hand.
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
G) Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.
Dimming the mirrors
> The interior and exterior mirrors dim automati-
cally when light shines on them, for example
from headlights on a vehicle behind you.


ZX WARNING
— If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid >

Fig. 51 Lever: windshield wipers.
> Move the windshield wiper lever SY to the cor-
responding position:
@ Windshield wipers off
@ Rain sensor/intermittent mode. The wind-
shield wipers switch on once the vehicle speed
exceeds approximately 2 mph (4 km/h) and it is
raining. The higher the sensitivity of the rain sen-
sor that is set (switch © to the right), the earlier
the
windshield wipers react to moisture on the
windshield. You can deactivate the rain sensor
mode, which switches the interval mode on. In
intermittent mode, you can adjust the interval
time using the switch ©.
» Applies to: MMI: Select on the home screen:
VEHICLE > Light & Visibility > Rain sensor.
@ Slow wiping
@ Fast wiping
@ Single wipe. If you hold the lever in this posi-
tion longer, the wipers switch from slow wiping
to fast wiping.
© Clean the windshield @. The number of wipes
and afterwipes depends on how long the lever is
held in position ©).
The wipers wipe one time after several seconds of
driving to remove water droplets. You can switch
this function off by moving the lever to position
© within ten seconds of the afterwipe. The after-
wipe function is reactivated the next time you
switch the ignition on.
66
If you hold the lever in position ©) for longer
than half a second, the edge wiping feature will
be activated. This moves the windshield wipers
closer to the edge of the windshield and per-
forms an afterwipe to clean the residue that re-
sults from the wiping process from the edge of
the windshield. The function is available when
driving at speeds up to 75 mph (120 km/h).
The headlight washer system* operates only
when the low beam headlights are on. If you
move the lever to position 6), the headlights and
the night vision assist camera”* are cleaned at in-
tervals.

Z\ WARNING
— The rain sensor is only intended to assist the
driver. The driver may still be responsible for
manually switching the wipers on based on
visibility
conditions.
— The windshield must not be treated with
water-repelling windshield coating agents.
Under unfavorable conditions, such as wet-
ness, darkness, and when the sun is low,
these coatings can cause increased glare,
which increases the risk of an accident. They
can also cause wiper blade chatter.
— Properly functioning windshield wiper
blades are required for a clear view and safe
driving > page 67, Cleaning/changing wip-
er blades.

@) Note
— If there is frost, make sure the windshield
wiper blades are not frozen to the wind-
shield. Switching on the windshield wipers
when the blades are frozen to the wind-
shield can damage the wiper blades.
— Prior to using a car wash, the windshield
wiper system must be switched off (lever in
position @). This prevents the wipers from
switching on unintentionally and causing
damage to the windshield wiper system.
@) Tips
— The windshield wipers switch off when the
ignition is switched off. You can activate the
windshield wipers after the ignition is

Driving

— D (Drive)
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 the nearest gear, move the selector
lever forward or back until you feel the first
pressure point.
—To skip a gear (for example, move from “D” to
“R”), move the selector lever past the pressure
point in the desired direction.
— 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
Requirement: the ignition must be switched on.
The vehicle is secured from rolling away by the
parking lock when in the “P” gear.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the “P” button (2) on the selector lever.
— The “P” next to the selector lever will light up.
“P” engages automatically if you switch the en-
gine off while the “D” or “R” gear is selected. If
you switch the engine off in “N”, “P” will engage
automatically after approximately 30 minutes.
If you want to switch to another gear from “P”,
the engine must be running.
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 112.

Selecting the 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”.

brid modes are available in the “S” driving pro-
gram. The driving program or plug-in hybrid
mode will be automatically adjusted if it is not
compatible with an operation.

ZA\ WARNING
— Before you start driving, check if the label
for the desired selector lever position next
to the selector lever is lit up.
— Secure the vehicle against rolling before ex:
iting the vehicle > page 108.
— 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.
— Never select the “R" or "P” gears while driv-
ing. Doing so could cause an accident.
— The vehicle can roll even if the ignition is
switched off.

General information
Introduction
Applies to: vehicles with plug-in hybrid drive
All work done on the high-voltage system must
only be performed by certified high-voltage tech-
nicians at authorized Audi dealers or authorized
Audi Service Facilities in accordance with Audi
guidelines.
The high-voltage system is composed of the fol-
lowing high-voltage components, among other
things: the high-voltage battery, the power elec-
tronics, the electric motor, the high-voltage A/C
compressor, the high-voltage heater, the charg-
ing system and charging port, and the orange
high-voltage wiring.
The high-voltage battery is located in the lug-
gage compartment under the cargo floor and
does not require any maintenance from the driv-
er.


ZX 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 against the high-
voltage.
— 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 the orange high-

components. Only authorized repair facili-
ties that are certified may perform work on
the high-voltage system.
— Never damage, alter or remove the orange
high-voltage cable or disconnect it from the
high-voltage system.
— Never perform any work using cutting, shap-
ing or sharp-edged tools or heat sources
near the high-voltage system and high-volt-
age cables.
— Gases that escape from the high-voltage
battery can be poisonous or flammable.
— Damage to the high-voltage battery could
cause the high-voltage battery to leak im-
mediately or in the future, and poisonous or
flammable gases could escape. Do not in-
hale the gases!
— Do not expose yourself to any leaking fluids
and do not come into contact with them.
— The high-voltage battery electrolyte fluid is
caustic. If electrolyte fluid comes into con-
tact with the skin, flush the affected area for
at least 15 minutes with clean water. Then
wash the affected area with soap. Have the
affected area examined by a medical profes-
sional.

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 limited or switched off. Some
convenience functions, such as interior lighting
or power seat adjustment, may not be available
under certain circumstances. The convenience
functions will be available again when you 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 286. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places an especially high load on
