296 OperationTires and wheelsChecking tire pressure electronically
with the Tire Pressure Monitoring
System (TPMS), (USA only)The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
iThe T
ire P
ressure M
onitoring S
ystem
(TPMS) is equipped with a combination
low tire pressure/TPMS malfunction
telltale in the instrument cluster
(
page 27). Depending on how the
telltale illuminates, it indicates a low
tire pressure condition or a malfunction
in the TPMS system itself:
If the telltale illuminates continu-
ously, one or more of your tires is
significantly under-inflated. There is
no malfunction in the TPMS.
If the telltale flashes for 60 seconds
and then stays illuminated, the
TPMS system itself is not operating
properly.
Warning!
G
The TPMS does not indicate a warning for
wrongly selected inflation pressures. Always
adjust tire inflation pressure according to
the placard on the driver’s door B-pillar or, if
available, the supplemental tire pressure in-
formation on the inside of the fuel filler flap.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by care-
fully applying the brakes and avoiding
abrupt steering maneuvers.
Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat and can lead to tire failure.

Warning!
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. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

TM airbag deactivation
system
This system detects if a special system
compatible child restraint seat is in-
stalled on the front passenger seat. The
system will automatically deactivate
the passenger front airbag when such a
seat is properly installed (indicator
lamp 7 on the glove box comes on
and remains illuminated).
BabySmartTM compatible child seats
Special restraint system for children.
The sensor system for the passenger
seat prevents deployment of the pas-
senger front airbag if a BabySmart

compatible child seat is installed. See
your authorized Mercedes-Benz Center
for availability.
