- Fig. 1 Display: Indicator lamp with message
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.
The tyre pressure monitoring system makes use of the ABS sensors
to compare the rolling circumference and the vibration of the wheels.
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.
Monitoring of the tyre pressures is based on the tyre pressures
you have stored. 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 on the MMI
Link. The tyre pressures recommended for your vehicle are given
on the sticker on the end face of the driver's door
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.
- You are driving with the temporary spare wheel*.
Warning and indicator lamps
Loss
of pressure on one or more tyres
WARNING!. Check
the tyre(s) and change or repair the wheel. Check and adjust
the inflation pressures of all four tyres again and store the
new tyre pressures on the MMI
Link.
TPMS
(Tyre
Pressure
Monitoring
System)
Tyre pressure monitoring system! System
fault - If
TPMS appears and
the indicator lamp
in the
instrument cluster display flashes for approx. one minute and
then lights up continuously after you have switched on the ignition
or while you are driving, there is a fault in the system. Please
contact the nearest qualified workshop as soon as possible.
- If the tyre pressure indicator 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 indicator lamp may not light up immediately.
- 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.
Note
- If a malfunction occurs in the ESP/ABS system, the tyre pressure monitoring system will also be out of action.
- When driving with snow chains, a system malfunction can occur.
- The tyre pressure monitoring system on your Audi is specially matched to tyres with the marking "AO" or "RO". We recommend that you use these tyres.
