Note

  • The needles in the instrument cluster will sweep across the dials when you switch on the ignition.
  • The instrument lighting (illumination of dials and needles) is switched on when the ignition is on and the vehicle's lights are off. The instrument lighting is dimmed automatically as the daylight starts to fade. This function is intended to remind the driver to switch on the dipped-beam headlights in good time when light conditions become poor.

Coolant temperature gauge

The coolant temperature gauge only works when the ignition is switched on. In order to avoid possible damage to the engine, please read the following notes for the different temperature ranges.

Engine cold

If the needle is still in the lower range of the dial, this indicates that the engine has not yet reached operating temperature. Avoid high engine speeds, full acceleration and heavy engine loads.

Normal temperature

In normal operation the needle will settle somewhere in the centre of the dial once the engine has reached operating temperature. The needle may also go further up when the engine is working hard at high outside temperatures. This is no cause for concern provided the warning symbol Audi A4: Instruments. Warning symbol in instrument cluster in the display does not start flashing.

Warning symbol in instrument cluster Audi A4: Instruments. If the symbol  lights up in the display,

If the symbol Audi A4: Instruments. this means that either the coolant temperature is too high or the coolant level lights up in the display, this means that either the coolant temperature is too high or the coolant level is too low.

If the needle is at the top end of the dial, this means the coolant temperature is too high. Stop the vehicle, switch off the engine and wait for it to cool down. If the warning lamp starts flashing again after just a short distance, contact a qualified workshop.

Audi A4: Instruments. WARNING

  • Before opening the bonnet and checking the coolant level, please observe the warning information on, Working on components in the engine compartment.
  • Never open the bonnet if you can see or hear steam or coolant escaping from the engine compartment; there is a risk of being scalded. Wait until you can no longer see or hear escaping steam or coolant.

Audi A4: Instruments. Caution

  • Additional lights and other accessories in front of the air inlet reduce the cooling effect of the radiator. At high outside temperatures and high engine loads, there is a risk of the engine overheating.
  • The front spoiler also ensures proper distribution of the cooling air when the vehicle is moving. If the spoiler is damaged this can reduce the cooling effect, which could cause the engine to overheat. You should obtain professional assistance.

Rev counter

The rev counter indicates the number of engine revolutions per minute.

You should select a lower gear if the engine speed drops below 1500 rpm. The start of the red zone on the dial indicates the maximum engine speed which may be used briefly when the engine is warm and after it has been run in properly. However, it is advisable to change up a gear or move the selector lever to D (or lift your foot off the accelerator) before the needle reaches the red zone.

Audi A4: Instruments. Never allow the rev counter needle, fig. 2 to go into the red zone on the Caution

Never allow the rev counter needle, fig. 2 to go into the red zone on the dial for more than a very brief period: there is a risk of damaging the engine. The start of the red zone on the dial is different for some engine versions.
