Instrument cluster: Indicator lamp with message
Fig. 1 Instrument cluster: Indicator lamp with message
Applies to vehicles: with tyre pressure monitoring
The tyre pressure loss indicator in the instrument cluster informs the driver if the tyre pressure is too low or a system malfunction has occurred.
The tyre pressure loss indicator makes use of the ABS sensors to compare the rolling circumference and the vibration of the tyres. If changes in the inflation pressure are detected on one or more tyres, the driver is alerted by an indicator lamp and a message in the instrument cluster display Fig. 1. If only one tyre is affected, the display will indicate its position.
Each time you change a tyre, change the wheels round or change the tyre pressures on your vehicle (e.g. when switching from partial load to full load and vice-versa), you must store the new tyre pressures in the menu display ►Link. Monitoring of the tyre pressures is based on the tyre pressures you have stored. The tyre pressures recommended for your vehicle are given on the sticker attached to the driver's door pillar ►Link.
The rolling circumference and vibration can change and cause a tyre pressure warning if:
  • The inflation pressure in one or more tyres is too low.
  • The tyre has suffered structural damage.
  • The wheels were changed or the tyre pressures were changed and the new tyre pressures were not stored ►Link.
  • The vehicle load is not balanced (more load on one side).
  • There is more load on the wheels of one of the axles (e.g. when driving up or down a gradient).
  • You are driving with snow chains.
  • You are driving with the temporary spare wheel*.
  • Only one wheel of an axle has been changed.
Indicator lamps
- Loss of pressure on one or more tyres WARNING!. Check and change or repair the tyre(s). Check and adjust the tyre pressures again on all four wheels. Then store the tyre pressures in the menu display ►Link.
(Tyre Pressure Monitoring System) Tyre pressure! System fault. If appears and the indicator lamp in the instrument cluster display flashes for approx. one minute and then remains lit after you have switched on the ignition or while you are driving, there is a fault in the system. Check and adjust the tyre pressures for all four tyres and store the new tyre pressures ►Link. If the indicator lamp does not go out or if it comes on again after a short time, drive to a qualified workshop without delay and have the fault rectified.
WARNING!
  • If the tyre pressure loss indicator appears in the instrument cluster display, slow down immediately and avoid any severe braking or steering manoeuvres. As soon as you can do so safely, stop and check the tyres and the tyre pressures.
  • It is the driver's responsibility to ensure that the tyre pressures are correct. For this reason you must check the tyre pressures regularly.
  • Under certain conditions (e.g. driving at high speeds, on ice and snow or on poor road surfaces) the tyre pressure loss indicator may not appear immediately.
  • The use of run-flat tyres on your vehicle is NOT authorised! Unauthorised use can cause an accident or damage your vehicle.
Note
  • If a malfunction occurs in the ESC/ABS system, the tyre pressure loss indicator may also be out of action.
  • When driving with snow chains, a system malfunction can occur.
  • The tyre pressure loss indicator on your Audi is specially matched to "Audi Genuine Tyres" ►Link. We recommend that you use these tyres.
