Tyre pressure
monitor Wheel sensor miss-
ing
The tyre pressure monitor* is not receiv-
ing signals from one or more wheels
because:
R
a wheel without a suitable wheel sensor
is fitted (e.g. an emergency spare
wheel*).
R the battery on one of the wheel elec-
tronics unit is discharged.
R a wheel electronics unit has malfunc-
tioned.
A line is displayed in the multi-function
display for the tyre concerned instead of
the tyre pressure value. X
Have the tyre pressure monitor* and wheels
checked at a qualified specialist workshop.
Once wheels with suitable wheel sensors have
been fitted again, the tyre pressures are dis-
played in the multi-function display after driv-
ing for a few minutes. Tyre pressure
monitor currently unavail-
able
The tyre pressure monitor* is temporarily
deactivated. The voltage of the vehicle's
electrical system is too low or radio inter-
ference prevents the reception of sensor
signals. X
Drive on.
Once the causes have been eliminated, the tyre
pressure monitor* automatically reactivates
after a few minutes of driving. Practical advi

Risk of accident and injury
The operating safety of your vehicle could be compromised if service work is carried out improperly. You could lose control of the vehicle,
thereby causing an accident. Safety systems may also not be able to protect you or others as intended.
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Display messages Possible cause/consequence Possible solution
