Restarting Advanced TPMS
The TPMS usually recognizes new refer-
ence values automatically, for example
when you have
adjusted the tire inflation pressure
changed wheels or tires
mounted new wheels or tires
Warning!
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.
If you want to set new reference values
manually:
Using the Tire and Loading Information
placard on the driver's door B-pillar
( page 263) or, if available, the sup-
plemental tire inflation pressure
information on the inside of the fuel
filler flap ( page 247), make sure the
tire inflation pressure of all four tires is
correct.

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 ( page 263). Some
vehicles may have supplemental tire inflation
G
pressure information for driving at high speeds
( page 247) or for vehicle loads less than the
maximum loaded vehicle condition
( page 247). If such information is provided, it
can be found on the inside of the fuel filler flap.
Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu
appears in the multifunction display
( page 122).
