When the initialization of the tire pressure warning system has failed
■
Initialization can be completed in a few minutes. However, in the following cases, the set-
tings have not been recorded and the system will not operate properly. If repeated
attempts to record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by your Lexus dealer.
When operating the tire pressure warning reset switch, the tire pressure warning light
●
does not blink 3 times.
After carrying out the initialization procedure, the tire pressure warning light blinks for 1
●
minute then stays on after driving for about 20 minutes.
Registering ID codes (vehicles with the tire pressure warning system)
■
For some models: The ID codes of the tire pressure warning valve and transmitters for
two sets of wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with snow tires, if
the ID codes for the wheels of both normal tires and snow tires are registered before-
hand.
For information about changing ID codes at your Lexus dealer.
