— Audi drive select mode ......... 91
ZA WARNING
Applies to: vehicles with Audi virtual cockpit
If there is a severe malfunction in the instru-
ment cluster, the display may turn off. The wa
indicator light may also turn on. Stop the ve-
hicle safely. See an authorized Audi dealer or

authorized Audi Service Facility for assistance.

@ Tips
— The following pages will primarily show il-
lustrations of the multi-color analog instru-
ment cluster*. The display and/or position
of the element shown may vary in mono-
chrome instrument clusters or in the Audi
virtual cockpit*.
— You can select the units used for tempera-
ture, speed, and other measurements in the
Infotainment system > page 230.
— Speeds are displayed in mph (miles per
hour) or km/h (kilometers per hour).
— If there is a malfunction in the instrument
cluster, DEF will appear in the trip odometer
display. Have the malfunction corrected as
soon as possible.
— Depending on vehicle equipment, the in-
strument illumination (needles and gauges)
may turn on when the lights are off and the
ignition is switched on. The illumination for
the gauges reduces automatically and even-
tually turns off as brightness outside in-
creases. This function reminds the driver to
turn the low beams on at the appropriate
time.
Coolant temperature
display
Applies to: vehicles with a coolant temperature indicator
The coolant temperature display @) > page 14
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-
erating 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 || indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 311.
@) 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.
—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) > page 14 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 and
when it is warm. Before reaching the red zone,
you should shift into the next higher gear, choose
the "D" or "S" selector lever position, or remove
your foot from the accelerator pedal.
Displaying the tachometer
Applies to: vehicles with plug-in hybrid drive
> Open the first vehicle functions tab using the
<1/D button on the multifunction steering
wheel.
> Applies to: vehicles with analog instrument
cluster: Turn the left thumbwheel on the multi-
function steering wheel until the Tachometer
appears in the instrument cluster.

- The daytime running lights* automatically
turn on. In vehicles for certain markets, you can
switch the automatic daytime running lights on
and off in the Infotainment system.
AUTO* - The headlights automatically adapt to
the surrounding brightness.
300 - Parking lights
2D - Low beam headlights
Buttons
When you turn the light switch to the AUTO* or
low beam headlight ZO position, you can activate
the following:
220 - All-weather lights. The front lights are ad-
justed automatically so that there is less glare for
the driver from his or her own lights, for example
when roads are wet.
Q - Rear fog light(s)
Automatic headlight range control
Applies to: vehicles with headlight range control
Your vehicle is equipped with an automatic head-
light range control system that reduces glare for
oncoming traffic if the vehicle load changes. The
headlight range adjusts automatically.
Audi adaptive light
Applies to: vehicles with adaptive light
Adaptive light provides better visibility when it is
dark by adapting the lights to the road conditions
based on speed, such as on expressways, rural
roads, at intersections, and in curves. The adap-
tive lights only function when the light switch is
in the AUTO* position and the all-weather lights
are switched off.

Z\ WARNING
— Automatic headlights* are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head-
lights and to turn them on manually based
on the current 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.
—To prevent glare for traffic behind your vehi-
cle, the rear fog lights should only be turned
on in accordance with traffic regulations.
G) Tips
— Follow the regulations applicable to the
country where you are operating the vehicle
when stopping the vehicle and when using
the lighting systems.
— 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.
— The light sensor for the automatic head-
lights* is in the rearview mirror mount. Do
not place any stickers in this area on the
windshield.
— 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
does not affect the service life of the light-
ing.

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. >
