Warning!
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver's door B-
pillar or the tire inflation pressure label on the
inside of the fuel filler flap. If your vehicle has
tires of a different size than the size indicated
on the Tire and Loading Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
Possible causes/consequences and X Solutions
The TPMS (USA only) or Advanced TPMS (Canada only) detects a
loss of pressure in at least one tire.
X
Carefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers. Observe the traffic situation around you.
X
Read and observe messages in the multifunction display
( Y page 228).
If the tire inflation pressure in the respective tire(s) has (have) been
corrected, the combination low tire pressure/TPMS malfunction
telltale goes out after a few minutes of driving.
There is a malfunction in the TPMS.
X
Read and observe messages in the multifunction display
( Y page 228).
X
Have the TPMS checked at an authorized Mercedes-Benz
Center.
After the malfunction has been remedied, the combination low tire
pressure/TPMS malfunction telltale goes out after a few minutes
of driving.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly underinflated tire causes the tire
to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
