cation of a flat tire on page

Indication of a flat tire
The warning lamps come on in yellow
and red. In addition, an acoustic sig-
nal sounds. There is a flat tire or sub-
stantial loss of tire pressure.
1. Reduce your speed and carefully stop the
car. Avoid sudden braking and steering
maneuvers.
2. Identify the damaged tire. To do so, check
the tire pressure using the M Mobility Sys-
tem, refer to Producing the tire inflation
pressure on page
132 .
3. Repair the flat tire with the M Mobility Sys-
tem, refer to page
132 .
Malfunction
The warning lamps come on in yel-
low. The Flat Tire Monitor has a mal-
function or has failed. Have the sys-
tem checked as soon as possible.
Tire Pressure Monitor TPM*
The concept
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system. <
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences. <
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics has been
mounted, or if TPM is temporarily malfunction-
ing due to other systems or devices using the
same radio frequency.
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system. <
1. Start the engine, but do not start driving.
2. Press the button for approx. 4 seconds until
the warning lamp in the instrument cluster
lights up yellow. Warning lamp, refer to
