When registering ID codes
Before performing ID code registration,
make sure that no wheels with tire pres-
sure warning valve and transmitters
installed are near the vehicle.
Make sure to initialize the tire pressure
warning system after registering the ID

registering the ID codes, the initialized
values will be invalid.
As the tires will be warm when registra-

tires to cool before performing initializa-

procedure again and turn the engine
switch off before driving.

engine switch is turned to IGNITION
