Wheel Sensor(s)
Missing
One or more sensors malfunction (e.g. bat-
tery in one or more wheel sensor is empty).
One or more wheels without wheel sensors
mounted (e.g. spare tire).
No pressure value is shown on the multi-
function display for the tire in question.

Have the Advanced TPMS checked by an au-
thorized Mercedes-Benz Center.

Have the wheel sensors installed by an
authorized Mercedes-Benz Center.
The tire pressure for the respective tire is
shown in the multifunction display after a few
minutes of driving.
Tire Pressure
Please Rectify
The pressure is too low in one or more tires.
Or the tire pressures of the individual
wheels differ too radically from one anoth-
er.

Check and adjust tire inflation pressure as
required (
page 593).

728 Practical hintsFlat tire6Wheel wrench
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).

Fully collapse the jack, with handle
folded in (storage position),
(page 706).

Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor
(page 705).
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).i
Vehicles with Advanced TPMS:
Do not activate the tire inflation pressure moni-
tor until a full size wheel/tire with functioning
sensor has been placed back into service on the
vehicle.
