When replacing the tires or wheels, the
tire pressure warning valve and trans-
mitters must be installed to the wheels
which will be installed to the vehicle.
When new tire pressure warning
valves and transmitters are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. (

Replacing tires and wheels
If the ID codes of the tire pressure warning
valve and transmitters are not registered,
the tire pressure warning system will not
work properly. In this case, after driving for
about 10 minutes, the tire pressure warning
light will blink for approximately 1 minute
and then illuminate to indicate a system
malfunction.
■
The tire pressure warning system
must be initialized in the following
circumstances:

When the tire inflation pressure is
changed such as when changing
traveling speed or load weight.

When the tire inflation pressure is
changed such as when the tire size
is changed.

When rotating the tires.

After performing the transmitter ID
code registration procedure.

the power switch off and wait 20
minutes or more.
The initialization procedure cannot be
started while the vehicle is moving.
2 Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level.
Make sure to adjust the tire pressure to the

Make sure to install the tire valve caps.
If the tire valve caps are not installed,
water may enter the valves of the tire
