Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the
knob in the desired direction.
The mirror moves from the reversing position
back to the original position:
— When you switch the ignition off
— When you drive forward at speeds faster than 9
mph (15 km/h).
— When the knob is no longer in the position for
the front passenger exterior mirror

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.
Gi) 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
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.

ZA WARNING
—If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
can irritate the skin, eyes and respiratory
system. If there is contact with the fluid,
flush immediately with plenty of water. Con-
sult 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.
— If electrolyte fluid comes into contact with
the eyes, flush them thoroughly with plenty
of clean water for at least 15 minutes and
then seek medical attention.
— If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes, and then
clean with soap and water and seek medical
attention. Clean affected clothing and shoes
thoroughly before wearing again.
— If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro-
fessionals. Seek medical attention immedi-
ately.

and afterwipes depends on how long the lever is
held in position G).
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.
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 ©), the headlights and
the night vision assist camera* are cleaned at in-
tervals.
@ Wipe the rear window ©. The number of
wipes depends on the windshield wiper move-
ment.
The rear wiper automatically switches on when
the reverse gear is selected and the front wind-
shield wipers are on and running.
Clean the rear window &. The number of
wipes depends on how long the lever is held in
position (8). This may also clean the rearview
camera, depending on the vehicle equipment.

A 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 56, 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.
(i) Tips
— The windshield wipers switch off when the
ignition is switched off. You can activate the
windshield wipers after the ignition is
switched on again by moving the windshield
wiper lever to any position. The single wipe
function (lever in position @)) also functions
when the ignition is switched off.
— Worn or dirty windshield wiper blades result
in streaking. This can affect the rain sensor
function. Check your windshield wiper
blades regularly.

Sitting correctly and safely

— The distance between your upper body and the
steering wheel or instrument panel is at least
10 inches (25 cm)
— The distance between your knees and the in-
strument panel is at least 4 inches (10 cm)
— Your thighs are lightly supported by the front
surface of the seat
— The backrest is in an upright position and your
back is resting against it
— You have a sufficient view of the area around
the vehicle
— You have a clear view of the instrument cluster,
indicator lights, and the head-up display*
Seat settings menu: quick access
Applies to: vehicles with seat settings in the MMI
If you press on the image of the driver's or front
passenger's seat in the climate control system
menu > page 84, fig. 78 @), you will go directly
to the seat settings for that seat.

Z\ WARNING
— If you are too close to the steering wheel or
instrument panel, the airbag system cannot
provide the optimal protection, which in-
creases the risk of injury and death.
—To reduce the risk of injury in the event of
sudden braking maneuvers or accidents,
never drive with the backrest reclined very
far. The airbag system and seat belts can on-
ly provide optimal protection when the back-
rest is in an upright position and the driver
is wearing the seat belt correctly. If the
backrest is angled back too far, the safety
belt can shift to soft areas of the body, such
as the stomach, which increases the risk of
injury.
—To reduce the risk of an accident, only adjust
the seats when the vehicle is stationary.
— Be careful when adjusting the seat. Lack of
control or attention when adjusting can re-
sult in injuries due to pinching to vehicle oc-
cupants both in the front seats and rear
seats.
— Never place objects in the driver's footwell.
Objects could shift and enter the area
around the pedals, which could prevent you
from using them. You would then be unable

60

to use the pedals if sudden driving or brak-
ing maneuvers were needed, which increas-
es the risk of an accident.
— Make sure that the floor mats are always se-
curely attached.
—To reduce the risk of an accident, never place
additional floor mats or other floor covers
over the installed floor mats, because this
reduces the pedal's range of motion and can
impair pedal operation.
—To reduce the risk of injury, never place your
feet on the instrument panel, out of the
window, or on the seat surfaces. This also
applies to passengers in the rear seats.

@) Note
To reduce the risk of damage, be very careful
when adjusting the seat to make sure the
head restraints do not come into contact with
the headliner or the sunroof*.

Driving

@ For the sake of the environment
Avoid actions that are damaging to the envi-
ronment. Show respect for the natural envi-
ronment and remain on marked routes.
@ Tips
Clean your vehicle after driving offroad. Dirt
and stones falling off your vehicle can affect
other road users.
Driving through water
If you must drive through water, follow these in-
structions:
— Check the stability of the ground, the current,
and the water depth. If the ground is unstable,
there is a strong current, or there are waves,
the water must only reach up to the lower edge
of the body at the most.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash
above the lower edge of the body. Oncoming
vehicles could also create waves.
— Do not stop the vehicle while in the water.
— Drive in reverse.
— Do not switch off the drive system.

Z\ WARNING
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
@) Note
Vehicle components such as the motor, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
tele
@) Tips
If possible, avoid driving through salt water
because it increases the risk of corrosion. Use
fresh water to clean any vehicle components
that come into contact with salt water.

Hill descent assist
Applies to: vehicles with hill hold assist
The “& button is located in the function bar on
the lower display. It lights up when the system is
turned on.
Hill descent assist can assist you when driving
down hills by maintaining a constant vehicle
speed by automatically braking all four wheels.
You can adjust the speed using the accelerator
and brake pedals. The regulation depends on the
hill and the vehicle speed.
> Switching on: press e
> Switching off: press “ again.
Active regulation
Regulation begins shortly after you start driving
and is possible at speeds up to approximately 19
mph (30 km/h) and on hills that have an approxi-
mately 6-60% grade. If these conditions are met,
regulation will be activated and the indicator
light will turn on.
Ready mode
If one of the requirements for active regulation is
not met, the system will be in ready mode. The
a indicator light will turn on. Once the require-
ments are met again, the system will be able to
provide active regulation again.

ZA\ WARNING
— Be ready to apply the brakes at all times
when using the hill hold assist.
— Always adjust the speed to the visibility,
weather, road, and traffic conditions. The
system cannot replace the driver's atten-
tion.
— The system cannot maintain a constant vehi-
cle speed in all situations, for example when
on smooth or slippery ground. This can in-
crease the risk of an accident.
G) Tips
If you select the Audi drive select* offroad
mode, hill descent assist will switch on.

101

Driving dynamic

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.
Power steering
The ESC can also support vehicle stability
through steering.

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-
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.
— As the vehicle load increases, especially the
roof load, the vehicle's center of gravity also
increases along with the risk of the vehicle
tipping. To reduce the risk of an accident, al-
ways adapt your driving style to the current
conditions and avoid sudden driving maneu-
vers.

@) 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 motor power.
106
— You may hear noises when the systems de-
scribed are working.
The So button (or #, depending on the model)
for controlling the ESC is located in the center
console, in front of the selector lever. The ESC is
automatically switched on when the ignition is
switched on.
Limiting ESC
In some situations, it may make sense to limit
the stabilizing function of the ESC so that the
wheels can spin, for example to rock a vehicle to
free it when it is stuck or to drive with snow
chains. The ESC can also be limited to provide
more sporty driving characteristics with fewer
stabilizing corrective actions.
—To limit the ESC, press the 0 button briefly.
The B indicator light will turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Depending on the Audi drive select mode that is
selected, one of the following ESC modes will be
selected automatically:
— sport - this mode is designed for driving ona
level surface. It is used in all Audi drive select
modes except offroad.
— offroad - this mode is suited for driving offroad
and is designed for uneven terrain or loose
ground. If you select the offroad Audi drive se-
lect mode, the offroad ESC mode will be auto-
matically used.
Switching off ESC
For a more active control of the vehicle where the
stabilizing functions of the ESC cannot intervene,
the ESC can be switched off.
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

4KE012721BF
Driving dynamic


ZA WARNING
— When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin
and the vehicle could swerve, especially on
slick or slippery road surfaces. When there is
a heavy vehicle load and sudden driving ma-
neuvers, it may not be possible to prevent
the vehicle from tipping under certain cir-
cumstances, which increases the risk of an
accident.
— Because of the increased risk of an accident,
only drive with the ESC switched off or limit-
ed when it is necessary. Reactivate the ESC
as soon as possible.

@) Tips
— If you select the Audi drive select* offroad
mode, hill descent assist will switch on.
— If the ESC is limited, switched off, or mal-
functioning, systems with an automatic
braking intervention function may not be
fully available.
— If malfunctions occur in other systems or
certain driver assist systems are active, the
ESC must be switched on by the system. The
ESC
may switch on automatically and can-
not be operated with the button.
BA fs i BB & Stabilization control (ESC/
ABS): malfunction! See owner's manual
There is a malfunction in the ABS or EDL. This al-
so causes the ESC to malfunction. The brakes still
function with their normal power, but ABS is not

Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
Other indicator lights
ira blinks while driving, the ESC is actively reg-
ulating. Operating noises may occur. If the indi-
cator light stays on, the ESC has been switched
