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 285) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
୴ page 269), 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 140).
̈ Press the j or k button repeat-
edly until you see the flowing message:
Tire pressure
monitor active
Reactivation possible:
R-button
̈ Press the reset button.
The following message will appear in
the multifunction display:
Check current
tire pressure?
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 loose control over the vehicle.
i
Reactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure 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 285).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
୴ page 292) or for vehicle
loads less than the maximum loaded
vehicle condition (
୴ page 292). If such
information is provided, it can be found
on the inside of the fuel filler flap.
