Q When rotating the tires
Make sure that the engine switch is OFF. If
the tires are rotated while the engine switch
is in ON, the tire position information will
not be updated.
If this accidentally occurs, either turn the
engine switch to OFF and then to ON, or
initialize the system after checking that the
tire pressure is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
The tire pressure warning system of
this vehicle adopts a 2-type warning
system
z When “Adjust Pressure” is dis-
played (Normal Warning)
The tire pressure warning light comes on
and a buzzer sounds when the tire inflation
pressure becomes low due to natural air
leakage or outside temperature. (Ways of
coping:oP.589, 633)
z When “Immediately Check Tire
when Safe” is displayed (Emergency
Warning)
The tire pressure warning light comes on
and a buzzer sounds when the tire inflation
pressure becomes low suddenly due to a
blowout. (Ways of coping: oP.589, 597)
However, the system may not be able to
detect sudden tire ruptures (bursting, etc.).

tire pressure warning system can be
displayed on the multi-information
display.
The unit can be changed.
