Instrument cluster

Depending on vehicle equipment, the RS Per-
formance or RS Runway layout will be automati-
cally set when switching into the RS modes
=>page 111.
Adjusting the additional display
Depending on the vehicle equipment, the addi-
tional displays that can be selected may vary.
» Applies to: MMI: Select on the home screen:
SETTINGS > Display & brightness > Audi virtu-
al cockpit > Configure.
> Select the desired additional display.
Reducing the display
Depending on the vehicle equipment, you can
hide the central area in the instrument cluster.
> Select on the instrument cluster: vehicle func-
tions tab > [=] button > Reduced display.
Coolant temperature
display
The coolant temperature display @) > page 12
only functions when the ignition is switched on.
To reduce the risk of engine damage, please ob-
serve the following notes about the temperature
ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
eration, and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the g indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 248.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
14
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer (2) 9 page 12 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
cates the maximum permissible engine speed for
all gears once the engine has been broken in. Be-
fore reaching the red zone, you should shift into
the next higher gear, select the "D" or "S" selec-
tor lever position, or remove your foot from the
accelerator pedal.
Engine speed limitation
If the BA indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This will protect the en-
gine components, for example during a cold start
or from overheating.
The engine speed limitation is deactivated if you
release the accelerator pedal while the engine is
at normal operating temperature.
If the engine speed limitation was activated by
an engine control malfunction, the By indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
C) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer
The trip odometer and odometer are displayed in
the status bar G) > page 12.

traffic if the vehicle load changes. The headlight
range adjusts automatically.
Audi adaptive light
Applies to: vehicles with Audi adaptive light
Audi adaptive light provides better visibility when
driving in the dark. The lights are adapted to the
road conditions based on speed, such as when
driving on expressways, rural roads, at intersec-
tions, and around curves. The adaptive light only
functions when the automatic headlights are ac-
tivated.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Automatic headlights are only intended to
assist the driver. The driver is still responsi-
ble for controlling the headlights and may
need to switch them on and off manually
depending on light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.

@ Tips
— If the vehicle battery has been discharging
for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.
— When using lighting equipment, the driver
is responsible for adhering to any local ap-
plicable regulations while driving and when
parking the vehicle.
— Only the front headlights turn on when the
daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—Incool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog
over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This

Lights and Vision


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
Automatic dimming rearview mirror
Applies to: vehicles with automatic dimming mirrors


> The interior and exterior mirrors dim automati-
cally when light shines on them, for example
from headlights on a vehicle behind you.

ZA WARNING
Applies to: vehicles with automatic dimming mirrors
—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.

@) Note
Applies to: vehicles with automatic dimming mirrors

© 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.
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 SJ. 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.

— Properly functioning windshield wiper
blades are required for a clear view and safe
driving > page 58, Cleaning/changing wip-
er blades.



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.

58
@) 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
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.
— The washer fluid nozzles for the windshield
washer system are heated when the ignition
is on if the outside temperature is low.
— When stopping temporarily, such as at a
traffic light, the speed of the windshield
wipers automatically reduces by one level.
