Audi A4 Owners Manual
Tyre pressure monitoring system
The tyre pressure monitoring display in the instrument cluster informs the driver if the tyre pressure is too low or a system malfunction has occurred.
Display: Warning message with symbol and text
Display: System fault ("Systemstörung")
The tyre pressure monitoring system makes use of the ABS sensors to compare the rolling circumference and the vibration of the wheels. The display in the instrument cluster alerts the driver if changes are detected on one or more wheels. If only one tyre is affected, the display will indicate its position ⇒ fig. 27.
Each time you change a tyre or the tyre pressures on your vehicle, you must store the new tyre pressures via the sound system or MMI*.
The rolling circumference and vibration can change if:
- • The tyre pressure is too low
- • The tyre has suffered structural damage
- • The air pressure in one or more tyres was changed and the new tyre pressures were not stored, “Storing the tyre pressures”
- • The wheels were changed and the new tyre pressures were not storedgggggg 41, “Storing the tyre pressures”
- • There is a greater load on the wheels of one axle (e.g. if you are carrying more passengers or luggage)
- • The road surface under the left wheels is different to the road surface under the right wheels for a long period
Warning lamp Tyre pressure ! System
If the warning lamp flashes for
TPMS (Tyre Pressure Monitoring System) Tyre pressure ! System malfunctiongggggg 40, fig. 28 will also be displayed in the instrument cluster. Please contact the nearest qualified workshop as soon as possible.
- • If the tyre pressure warning lamp 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 warning lamp may not light up immediately or not at all.
- • Please ask your Audi dealer or qualified workshop whether run flat tyres can be used on your vehicle. Unauthorised use of these tyres can invalidate the vehicle's type approval for use on public roads. Furthermore, this could cause damage to your vehicle and possibly also result in an accident.
Storing the tyre pressures
When you change a tyre or the tyre pressure on your vehicle, you must store the new tyre pressure via the sound system or MMI*.
