1 One or more tires is or has deflated rapidly. Carefully bring the
vehicle to a halt, avoiding abrupt steering and braking maneuvers.
For reference on changing wheels, see page 348.
2 The tire pressure on one or more tires is already below minimum
value. Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. For reference on changing
wheels, see page 351.
3 For tire inflation pressure monitor, see page 152.4 Tire pressure in one or more tires is low. Check and correct tire
pressure according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
5 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
6 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
7 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.
