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.

very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the engine.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A\.

ZA WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.
