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
gau ge of a n air h ose, e.g. gas sta tion equ ipment, and th e
vehicle’s multifunction display can occur. The vehicle’s
multifunction display of the tire inflation pressure
monitor is a more precise reading.Activation of tire inflation pressure monitor
Activation of tire inflation pressure monitor is
necessary if tire inf lation pressure is being changed,
wheels or tires are replaced, or new wheels are installed
on the vehicle.
Tire inf lation pressure should be checked and corrected
according to the label affixed inside the fuel filler flap.
For a detailed description, refer to page 345.
Turn electronic key in starter switch to position 2 (the
engine must not be running).
Notes:
When checking the tire inf lation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 335 for location of the spare wheel, and
page 345 for tire inflation pressure.
