Tires and wheels
Reactivating Advanced 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.
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.
Using the tire Tire and Loading Informa-
tion placard on the driver's door B-pillar
( page 585) or, if available, the sup-
plemental tire inflation pressure
information on the inside of the fuel fill-
er flap ( page 570), make sure the tire
inflation pressure of all four tires is cor-
rect.

Reactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire inflation pressure should only be adjusted
on cold tires. Observe the recommended tire in-
flation pressure on the Tire and Loading Informa-
tion placard on the driver's door B-pillar
( page 585). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds ( page 591) or for vehi-
G
cle loads less than the maximum loaded vehicle
condition. If such information is provided, it can
be found on the inside of the fuel filler flap
( page 570).
i
After wheel rotation or sensor replacement,
the vehicle must be parked for 20 minutes be-
fore attempting to reactivate the TPMS.
