and controls
Tire inflation pressure monitor
Notes:
Following a tire inflation pressure reactivation process
the real tire inflation pressures are displayed only after
a few minutes travel time.
Possible differences between readings of a tire pressure
gauge of an air hose, e.g. gas station equipment, and the
vehicle's multifunction display can occur. The vehicle's
multifunction display of the tire inflation pressure
monitor is a more precise reading.
