Mercedes-Benz 2006 E -Class Wagon Operator's Manual page 338

TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.
i
If a condition causing the TPMS to mal-
function develops, it may take up
to 10 minutes for the system to signal
a malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i
Operating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunction.
Tires and wheels
Reactivating the TPMS*
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Warning!
It is the driver's responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might loose control over the vehicle.
Using the tire placard on the driver's
door B-pillar ( page 328) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap ( page 312), make sure the tire
inflation pressure of all four tires is cor-
rect.
