Tire inflation pressure warnings
If the system detects a significant loss of
tire inflation pressure in one or more than
one tire, a message appears in the multi-
function display.
Example illustration
In addition, a warning signal sounds.
Restarting the TPMS
The TPMS must be restarted 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 and Loading Information
placard on the driver’s door B-pillar
(
୴ page 307) or, if available, the
supplemental tire inflation pressure
information on the inside of the fuel
filler flap (
୴ page 291), make sure the
tire inflation pressure of all four tires is
correct.
̈ Switch on the ignition (୴ page 37).
̈ Press button è or ÿ on the
multifunction steering wheel repeat-
edly until the standard display menu
appears in the multifunction
display (
୴ page 127).
̈ Press button j or k repeatedly
until the following message appears in
the multifunction display:
Tire Pressure Monitor
Active
Menu: R-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
Restart the TPMS after adjusting the tire in-
flation pressure to the inflation pressure recom-
mended for the vehicle operating condition. Tire
pressure should only be adjusted on cold tires.
Observe the recommended tire inflation pres-
sure on the Tire and Loading Information placard
on the driver’s door B-pillar (
୴ page 307). Some
vehicles may have supplemental tire inflation
pressure information for driving at high speeds
(
୴ page 313) or for vehicle loads less than the
maximum loaded vehicle condition
(
୴ page 313). If such information is provided, it
can be found on the inside of the fuel filler flap.
