operate properly
●Do not move the vehicle backward
during registration. Registration is started again from the beginning and it may take longer than usual.
●When another vehicle is running the side of the vehicle such as in heavy traffic, it
may take longer to detect the vehicle’s tire pressure warning valves and trans-mitters.
●If tire pressure warning valves and trans-mitters are in the vehicle, the ID codes
may not be registered.

procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable
