Instrument cluster

instrument cluster display turns on, the coolant
temperature is too high > page 238.
C) 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 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 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 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.
CG) 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 line ©) > page 12.
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
> Select on the instrument cluster: vehicle func-
tions tab > EJ button > Reset mi.
(i) Tips
Distances are displayed in mi (miles) or km
(kilometers).
Outside temperature
display
The outside temperature is displayed in the sta-
tus line ©) > page 12.
If your vehicle is stationary or if you are driving at
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.

Z\ 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.
