The laser high beams are switched on at speeds
above approximately 44 mph (70 km/h), when
the high beams are activated. The Ea indicator
light turns on if the high beams are switched on.
The E indicator light turns on if the laser lights
are switched on.
The laser beam is switched back off when the
speed decreases below approximately 30 mph
(50 km/h) or when the high beam assistant
switches the LED headlights off.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras © page 154.
— All repair procedures on the headlights must
be performed by an authorized Audi dealer

— Once 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

ZX 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 out-
side mirrors: If the mirror housing was
moved by force (for example, by running in-
to an object when maneuvering the vehicle),
the mirror must be folded all the way in us-
ing the power folding function. The mirrors
will make a loud noise when they latch into
place. The mirror housing 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
outside mirrors: If the mirror housing was
moved by outside forces (such as by an im-
pact while maneuvering), you must move
the mirror housing back into 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
— Certain settings are stored automatically in
the active personal profile.
— If the power adjusting function malfunc-
tions, 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 automat-
ically when light shines on them, for example
from headlights on a vehicle behind you.

ZX WARNING
— If the glass on an automatic dimming mir-
ror* breaks, electrolyte can leak out. This
liquid can irritate the skin, eyes and respira-
tory system. If there is contact with the flu-
id, 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.
— 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.



Q) Note
If the glass on an automatic dimming mirror*
breaks, electrolyte can leak out. This liquid
damages plastic surfaces and paint. Clean
this liquid as quickly as possible, for example
with a wet sponge.

— If the light reaching the rearview mirror is
obstructed, the automatic dimming mirror*
will not function correctly.
— The automatic dimming mirrors* do not dim
when the interior lighting is turned on or re-
verse gear is selected.

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 69, 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.
G) 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 >

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
If you press on the image of the driver's or front
passenger's seat in the climate control system
menu & page 104, fig. 95 @, you will go directly
to the seat settings for that seat.

ZA 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
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.
G) Tips
At the same time, only move the respective
seat using the controls.

Adjusting the front seats with buttons
You can adjust the basic settings using the but-
tons.

Sitting correctly and safely


then the safety belt's protective function
will be impaired in the event of an accident.
Make sure the safety belt is at the right
height and is routed correctly for the pas-
senger using it.
—A safety belt that is too loose may lead to in-
juries during an accident, because your body
will move farther forward due to kinetic en-
ergy and will be stopped abruptly by the
belt.
— Heavily bulky, loose clothing (for example, a
coat over a sports jacket) may prevent the
seat and safety belts from functioning cor-
rectly.
— Do not position the safety belt over hard or
breakable objects (such as glasses, pens,
etc.).
— The lap belt portion of the safety belt must
sit as low as possible on the lap of pregnant
women and lie flat under the belly.
@) Note
Make sure that there are no hook-and-loop
fasteners or sharp objects such as zippers or
rivets on clothing in the area where the safety
belt is worn. Otherwise, the safety belt could
be damaged.

belt for the corresponding rear seat is not fas-
tened.
EB - If this indicator light turns on, the safety
belt for the rear seat has been fastened.

Driving

@) 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 126. 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 283.

Driving dynamic

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

Z\ 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.

134

— 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.
@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The So button for controlling the ESC is located
in the center console, in front of the selector lev-
er.


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 ESC, press the oF 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 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.

152

Z\ WARNING
— Never turn off trailer mode while driving
when a trailer is hitched, because then the
restrictions for controlling the vehicle level
will be turned off.
— Driving with a trailer on unpaved roads when
the vehicle is raised may change the vehicle
handling. Adapt your speed.
— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the ve-
hicle manually.
() Note
— Applies to: vehicles with air suspension: Se-
lect the Audi drive select* comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
— Attachments retrofitted on the vehicle may
cause damage, especially on the trailer
hitch ball head. In cases of damage, have
the function checked by an authorized Audi
dealer or authorized Audi Service Facility.
G) Tips
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
— Having the vehicle inspected between the
inspection intervals is recommended if you
tow a trailer frequently.

— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
