Do not initialise the runflat indicator RPA with
snow chains fitted, as it may give incorrect read‐
ings.
Do not reset the Tyre Pressure Monitor with
snow chains fitted, as it may give incorrect read‐
ings.
When driving with snow chains fitted, activate
Dynamic Traction Control DTC briefly as re‐
quired in order to optimise traction.
Maximum speed with snow
chains
When snow chains are fitted, do not exceed
50 km/h, 30 mph.
Tyre Pressure Monitor
Principle
The system monitors the tyre inflation pressure
in the four fitted tyres. The system warns if the
tyre inflation pressure in one or more tyres has
dropped.
General
Sensors in the tyre valves measure the tyre infla‐
tion pressure and tyre temperature.
With the tyre settings in iDrive, the system can
display the predefined nominal pressures auto‐
matically and compare them with the current tyre
inflation pressures.
If the vehicle is fitted with tyres which are not lis‐
ted in the tyre inflation pressure information on
the vehicle, for example tyres with special appro‐
val, the system must be actively reset. The cur‐
rent tyre inflation pressures are then accepted as
the specified values.
When operating the system, please also comply
with the information and notes in the chapter on
tyre inflation pressure.
For further information:
Tyre inflation pressure, see page 318.
Safety note
WARNING
The display showing the specified tyre inflation
pressures does not replace the tyre inflation
pressure information on the vehicle. If incorrect
data has been entered into the tyre settings,
the specified tyre inflation pressures will also be
incorrect. As a result, reliable signalling of a loss
of tyre inflation pressure can no longer be guar‐
anteed. There is a risk of injury and material
damage. Make sure that the tyre sizes of the
fitted tyres are displayed correctly and that they
match the specifications on the tyres and in the
tyre inflation pressure information.
Operating requirements
The following requirements must be met for the
system, otherwise reliable signalling of a loss of
tyre inflation pressure is not ensured:
After every tyre or wheel change, the correct
specifications for the fitted tyres must be en‐
tered in the tyre settings.
The Tyre Pressure Monitor only becomes ac‐
tive after a journey of several minutes:
After a tyre or wheel change.
After a reset, in the case of tyres with spe‐
cial approval.
After changing the tyre setting.
In the case of tyres with special approval:
After every tyre or wheel change, a reset
must be carried out when the tyre inflation
pressures are correct.
A reset must be carried out after the tyre
inflation pressure has been adjusted to a
new value.
