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.
̈ Using the tire placard on the driver’s
door B-pillar (
୴ page 296) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
୴ page 283), make sure the tire
inflation pressure of all four tires is cor-
rect.
̈ Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(
୴ page 141).
̈ Press the j or k button repeat-
edly until you see the flowing message:
Tire pressure
monitor active
Menu: R-button
̈ Press the reset button (୴ page 27).
The following message will appear in
the multifunction display:

Yes
̈ Press the æ button.
The following message will appear in
the multifunction display:

After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s
specified range. Afterwards the current
tire inflation pressures are accepted as
reference pressures and then moni-
tored.
If you wish to cancel activation:
̈ Press the ç button.
Warning! G
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 lose control over the vehicle.
i
Reactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the placard on the driver’s door
B-pillar (
୴ page 296). Some vehicles may have
supplemental tire pressure information for driv-
ing at high speeds (
୴ page 302) or for vehicle
loads less than the maximum loaded vehicle con-
dition (
୴ page 302). If such information is pro-
vided, it can be found on the inside of the fuel
filler flap (
୴ page 283).
