WHEELS AND TIRES
474
After changing wheels, always calibrate the sys-
tem to avoid false warnings.
TPMS does not replace the need for regular tire
inspection and maintenance.
NOTE
If you change to tires with a different dimen-
sion than the factory-installed ones, the
TPMS system must be calibrated for these
tires.
TPMS cannot be turned off.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
