The tachometer 2 displays the engine speed in revolutions per minute (RPM). The beginning of the red zone in the tachometer indicates the maximum permissible engine speed for all gears once the engine has been broken in. Before reaching the red zone, you should shift into the next higher gear, select the "D" or "S" selector lever position, or remove your foot from the accelerator pedal.
Engine speed limitation
If the indicator light turns on, the engine will be automatically limited to the RPM displayed in the instrument cluster. This will protect the engine 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 example when downshifting. Drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.
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 begins varies depending on the engine.
Odometer
The trip odometer and odometer are displayed in the status bar 5.
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.

Tips
Distances are displayed in mi (miles) or km (kilometers).
Outside temperature display
The outside temperature is displayed in the status bar 5.
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 motor.
At temperatures below 41 ºF (+5 ºC), a snowflake symbol appears in front of the temperature display.
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 ºF (+5 ºC) and that ice can increase the risk of accidents.
