As you might have difficulty in identifying a flat or deflated
tire, a tire pressure warning system is provided on this
vehicle.
When replacing the wheels, be sure to install air pressure
sensors on the wheels.
There are 2 ways to set up the air pressure sensors.
a. Remove the sensor from the old wheel and install it to the
new wheel.
b. Use a new wheel and sensor.
You have to register an ID code for a new sensor. Up to 2
sets of codes can be registered. As one ID for the originally
installed sensor is registered at "MAIN" of the selector
switch, use the "2nd" position to register an ID for the new
sensor.
speed limit,
You do not need to re–register the ID code for any other
replacements. For the use of the originally installed tires,
put the selector switch at "MAIN" and for the use of tires
purchased later, put the switch at "2nd". For the sensor
selector switch, see page 224.
