Operation
Tires and wheels
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 352) or, if available, the sup-
plemental tire inflation pressure
information on the inside of the fuel
filler flap ( page 337), make sure the
tire inflation pressure of all four tires is
correct.

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 Tire and Loading Information
placard on the driver's door B-pillar
( page 352). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds ( page 358) or for vehi-
cle loads less than the maximum loaded vehicle
condition ( page 358). If such information is
provided, it can be found on the inside of the fuel
filler flap.
