tions tab > EE] button > Reduced display, or
> Press the VIEW button on the multifunction
steering wheel.
Coolant temperature
display
Applies to: vehicles with analog instrument cluster
The coolant temperature display @) > page 11
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 i] indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 220.
@) 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 @) 9 page 11 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 Bw 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 will be deactivated
once the engine has reached its normal operating
temperature and you have released the accelera-
tor pedal.
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

example when downshifting. Drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.
@) 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


Fig. 7 Instrument cluster: reset button
The trip odometer and odometer are displayed in
the status bar @) > page 11.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer
> To reset the trip odometer to zero, press the re-
set button @.
@® Tips
Distances are displayed in mi (miles) or km
(kilometers).
Outside temperature
display
The outside temperature is displayed in the sta-
tus bar @) 9 page 11.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
14
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the motor.
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.

Engine oil temperature
indicator
Applies to: vehicles with engine oil temperature indicator
Depending on the vehicle equipment, the engine
oil temperature %7 may be indicated by a bar in
the instrument cluster.
» Applies to: vehicles with Audi virtual cockpit:
Open the vehicle functions tab and switch to
the desired view > page 12.
> Applies to: vehicles with analog instrument
cluster: Open the lap timer > page 121.
When engine oil temperatures are low, the dis-
play --- °F (--- °C) appears in the instrument clus-
ter. The engine has reached its operating temper-
ature when the engine oil temperature is be-
tween 176 °F (80 °C) and 248 °F (120 °C) under
normal driving conditions. The engine oil temper-
ature may be higher if there is heavy engine load
and high temperatures outside. This is not a
cause for concern as long as the Ei => page 217
or & = page 217 indicator lights do not turn on.
Boost indicator
Applies to: vehicles with boost indicator
Depending on vehicle equipment, the current en-
gine load (meaning the current boost pressure)
may be indicated by a bar in the instrument clus-
ter.
» Applies to: vehicles with Audi virtual cockpit:
Open the vehicle functions tab and switch to
the desired view > page 12.

Warm and cold

The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (+22°C) or higher. The temperature
is controlled automatically.
You can switch the defroster on or off using the
& button. You can switch the function off by
pressing a knob (4).
@ Rear window defogger
The rear window defogger only operates when
the engine is running. It switches off automati-
cally after 10 to 20 minutes, depending on the
outside temperature.
To prevent the rear window defogger from
switching off automatically, press and hold @ for
more than three seconds. This is stored until the
ignition is switched off.
Vents
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con-
sole using the ridged thumbwheels. The levers
adjust the direction of the airflow from the vents.
Residual heat
You can activate the residual heat function when
the ignition is switched off by pressing the knob
@ (left side). The residual heat from the coolant
is used to heat the vehicle interior. The residual
heat function switches off automatically after
about 15 minutes.

ZA WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating* function. To reduce
the risk of injury, these individuals should
not use seat heating”.
