General notes If
at ire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the correct
sensors are installed on all wheels.
Information on tire pressures is displayed in
the multifunction display. After afew minutes
of driving, the current tire pressure of each
tire is shown in the Service menu of the
multifunction display. For further information
on displaying this message, refer to the
"Checking the tire pressure electronically"
section (Y page 344). 342
CheckWheels and tires

The tire pressure monitor has
ayellow
warning lamp in the instrument cluster for
indicatin gapressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whether atire pressure is too low or
the tire pressure monitor is malfunctioning:
R if the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
If the tire pressure monitor is malfunctioning,
it may take more than ten minutes for the tire
pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the
malfunction has been rectified, the tire
pressure warning lamp goes out after afew
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured at agas station with apressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated by apressure gauge are
higher than those shown by the on-board
computer .Inthis case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking the tire pressure

shown in the multifunction display.
If the vehicle was parked for longer than
20 minutes ,the Tire pressures will be
displayed after driving
afew minutes message is shown.
After ateach-in process, the tire pressure
monitor automatically detects new wheels or
new sensors. As long as aclear allocation of
the tire pressure value to the individual
wheels is not possible, the Tire Pressure Monitor Active displaym
essage is shown
instead of the tire pressure display. The tire
pressures are already being monitored.
i If an emergency spare wheel is mounted,
the system may continue to show the tire
pressure of the wheel that has been
removed for afew minutes. If this occurs,
note that the value displayed for the
position where the spare wheel is mounted
is not the same as the current tire pressure
of the emergency spare wheel.
