Opening and closing

Opening and closing
Central locking
You can lock and unlock the vehicle centrally. You
have the following options:
— Remote control key > page 27
— Sensors in the front door handles* > page 28
— Lock cylinder on the driver's door > page 30,
or
— Interior central locking switch > page 29
Turn signals
The turn signals flash twice when you unlock the
vehicle and flash once when you lock the vehicle.
If they do not flash when locking, check if all
doors and lids are closed.
Automatic locking (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex-
ceeded approximately 9 mph (15 km/h). The ve-
hicle will unlock again if the unlock function in
the central locking switch is pressed, the “P” gear
is engaged, or the ignition is switched off.
You can open the doors individually from the in-
side by pulling the door handle one time. To open
the rear doors* individually, you must pull the
door handle twice.
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close. You can set in the Infotainment
system whether only the driver's door or the en-
tire vehicle should be unlocked when unlocking
=> page 29.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the
remote control key is not in the vehicle. This re-
duces the risk of locking yourself out accidental-
ly.
The following conditions prevent you from lock-
ing your remote control key in the vehicle:
—If the driver's door is open, the vehicle cannot
be locked by pressing the & button on the re-
mote control key or by touching the locking
sensor* on a door.
— If the convenience key* that was last used is in-
side the luggage compartment, the luggage
compartment lid will automatically open again
after closing it >©.
— If the last convenience key* that was used is de-
tected inside the vehicle, the vehicle cannot be
locked from the outside for a brief time > ©.

ZA WARNING
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine or operate electrical equip-
ment such as power windows.
— No one, especially children, should stay in
the vehicle when it is locked from the out-
side, because the windows can no longer be
opened from the inside > page 30. Locked
doors make it more difficult for emergency
workers to get into the vehicle, which puts
lives at risk.

CG) Note
Applies to: vehicles with convenience key
— If the convenience key that was last used is
detected inside the passenger compart-
ment, then the vehicle cannot be locked
from the outside using the sensor. Take the
convenience key with you and lock the vehi-
cle again. Otherwise, the vehicle will not be
protected against unauthorized access.
— If you lock the vehicle using the button on
the vehicle key with the front passenger's
or rear door* open while accidentally plac-
ing the key in the passenger compartment
and closing the door, the vehicle will not
lock. The turn signals will flash several
times to indicate this. If you do not open

Lights and Vision

Q/® - adjusting the left/right exterior mirror.
Move the knob in the desired direction.
GA - Heat* the mirror glass depending on the out-
side temperature.
&) - Folding exterior mirrors*. To fold the mirrors
out, turn the knob to one of the other positions.
In the Infotainment system, you can select if the
mirrors fold in automatically when you lock the
vehicle > page 29.
Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
To help you see the curb when backing into a
parking space, the surface of the mirror will tilt
slightly when reverse gear is selected.
You can adjust the tilted mirror surface by turn-
ing the knob in the desired direction. When you
move out of reverse and into another gear, the
new mirror position is stored and assigned to the
key you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off.

Z\ 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
48
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 adjustment fails, both mirrors
can be adjusted by hand by pressing on the
edge of the mirror surface.
Dimming the mirrors
Your vehicle is equipped with a manual or auto-
matic* dimming rearview mirror.
Manual dimming rearview mirror
> Pull the lever on the bottom of the mirror back.
Automatic dimming rearview mirror*
> The interior and exterior mirrors dim automati-
cally when light shines on them, for example
from headlights on a vehicle behind you.

Z\ WARNING
Applies to: vehicles with automatic dimming rearview
mirror
Electrolyte fluid can leak out from broken mir-
ror glass. This liquid can irritate the skin, eyes
and respiratory system. If there is contact
with the fluid, flush immediately with plenty
of water. Consult a physician if necessary.
— Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi-
cle or, if this is not possible, open all of the
doors and windows as wide as possible. >

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


ZA WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not

place your foot under the brake pedal.
@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.
— Observe the important information for driv-
ing downhill > page 89. This especially ap-
plies when towing a trailer.
@) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.

— Also refer to the information about brake
fluid > page 313.
Ga i © Brakes: malfunction! Safely stop ve-
hicle
There is a malfunction in the brake system. If
EES / & and Ef also turn on, there is a malfunc-
tion in the ABS, ESC, and braking distribution.
Do not continue driving. See an authorized Audi
dealer or authorized Audi Service Facility for as-
86
sistance. Read and follow the other safety pre-
cautions > A\.
EG if @ Warning! Brake servo inoperative

Suspension
CET NRC Ld
Applies to: vehicles with suspension control
The adaptive dampers are an electronically-con-
trolled damping system. The firmness of the sus-
pension will adapt to the driving conditions and
the driving situation. The settings are dependent
on the selected Audi drive select* mode.
Ground clearance
The vehicle height and clearance can be influ-
enced by the following factors:
— Change in temperature
— Change in load

Z\ WARNING
To reduce the risk of injury, make sure no one
gets pinched when the vehicle level is chang-
ing, for example when cleaning the under-
body or the wheel housings.
@) Note
Always make sure there is enough clearance
above and below the vehicle. This is especially
important for entrances with height restric-
tions, for example, before driving into under-
ground garages. You could also scrape the
ground when driving over the edges of curbs
or on steep ramps, which could damage your
vehicle.

EET
| 8 | Suspension: malfunction! You can continue
driving
There is a malfunction. See an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.
Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
92
speed. The settings are dependent on the select-
ed Audi drive select* mode.
Progressive steering
Applies to: vehicles with progressive steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the steer-
ing wheel angle. The steering is very direct when
the steering wheel angle is sharp, and indirect
when the angle is low. This enables comfortable
maneuvering and a precise steering response at
higher driving speeds.
Messages
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
|2—| Steering: malfunction! Please stop vehicle
There is a malfunction in the electronic steering
lock. You cannot turn the ignition on. Do not tow
your vehicle because it cannot be steered. See an
authorized Audi dealer or authorized Audi Service
Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.
& Steering lock: malfunction! Please contact
Service
There is a malfunction in the electronic steering
lock. Drive immediately to an authorized Audi
dealer or authorized Audi Service Facility to have
the malfunction repaired.

Driving dynamic

Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal, or
— The braking force generated by the pressed
brake pedal is greater than the braking force
that
would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
risk of a collision.



ZA\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-

94

G) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The 0 button is located above the selector lev-
er in the center console.
The ESC is automatically switched on when the
ignition is switched on. It may make sense in
some situations to limit the ESC so that the
wheels can spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow, on unpaved ground, or
with snow chains
Limiting ESC (sport mode)
—To limit the ESD, press the 0 button briefly.
The B indicator light turns on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Switching off ESC
—To switch off the ESC, press and hold the oF
button for more than three seconds. The B
and Ea indicator lights turn on.

High-voltage system

battery should have a charge level between
40 % and 60 % when parked for a Long time.
If the battery charge level is below 3 %, never
park the vehicle for more than 21 days without
charging the high-voltage battery. Should you
have to park the vehicle for a long time, make
sure that the charge level is sufficient to help
prevent the battery from aging prematurely.
Frequent and consecutive charging of the high-
voltage battery when the charge level is above
98 % can also decrease the capacity of the
high-voltage battery. Make sure the charge lev-
el is below 98 % when you start the charging
process.
Should the vehicle be parked for longer than
2 days at temperatures below - 13 °F (-25 °C),
the high-voltage battery could freeze and not
be able to provide energy to the electric motor.
The battery will start working again, once it
warms up. The battery can be warmed up when
the outside temperature rises or when the vehi-
cle is garaged appropriately. The battery will al-
so warm up when being used (switching on the
air conditioner, the heater or by driving the ve-
hicle). Should you have to park your vehicle at
very low temperatures for longer than 1 day,
make sure that the high-voltage battery does
not freeze by parking the vehicle in a garage
that is heated or protected from the outside
temperature.
The high-voltage battery can be damaged and
the capacity can be decreased when the vehicle
is parked for longer than 24 hours when the
ambient temperature is higher than 118 °F
(48 °C). Always make sure that the high-voltage
battery is not exposed to temperatures above
118 °F (48 °C) for a long time.
Never park the vehicle in areas that are likely to
be flooded, such as beaches or river banks, and
never drive the vehicle in WATER, on flooded
roads or through water that is higher than the
bottom of the vehicle body. The high-voltage
battery, along with other vehicle components,
can be damaged severely if the high-voltage
battery is exposed to open water especially for
a longer time. However, you can drive through
water on roads under certain conditions
=> page 90.
Failure to heed any of these requirements can
age the battery prematurely and lead to a perma-
nent decrease of the high-voltage battery’s ca-
pacity.
G@) Tips
Always make sure that the high-voltage bat-
tery is not exposed to extremely low and high
temperatures as well as to water especially
for a longer time. Failure to protect and care
for the high voltage battery can lead to seri-
ous damage and/or a decrease of the capacity
void coverage under the New Vehicle Limited
Warranty.

Applies to: vehicles with plug-in hybrid drive
This section contains information you should
know about transporting your vehicle.
A lithium-ion high-voltage battery system equip-
ped in your vehicle has passed test 38.3 in ac-
cordance with the UN Tests and Criteria hand-
book and is manufactured in accordance with a
quality management program. The vehicle may
be transported with the high-voltage battery in-
stalled as conventional class 9 hazardous materi-
als without additional official authorization for
