Instrument cluster
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 > E] button > Reduced display.
Coolant temperature
display
Applies to: vehicles with a coolant temperature indicator
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 | indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 281.
@) 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 12 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
14
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.
Displaying the tachometer
Applies to: vehicles with plug-in hybrid drive
> Applies to: MMI: Select on the home screen:
SETTINGS > Display & brightness > Audi virtu-
al cockpit > Left dial > Tachometer or Com-
bined.
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 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 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.

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 67, 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

on inclines if the trailer is loaded.
— Audi recommends having the vehicle in-
spected between the inspection intervals if
you tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Pie Rie Relig
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.
