When registering ID codes
●
ID code registration is performed while driving at a vehicle speed of approximately 25
mph (40 km/h) or more.
●
Before performing ID code registration, make sure that no wheels with tire pressure
warning valve and transmitters installed are near the vehicle.
●
Initialize the tire pressure warning system after ID code registration. Initialization is dis-
abled if the system was initialized before registration.
●
After ID code registration, the tires are hot by driving. Initialize the tire pressure warn-
ing system after the tires become cold.
●
ID codes can be registered by yourself, but depending on the driving conditions and
driving environment, registration may take some time to complete.
■
Canceling the change wheel set mode
●
If turning the engine switch off when in the change wheel set mode before driving, the
change wheel set mode is canceled.
●
After driving when in the change wheel set mode, the change wheel set mode cannot
be canceled. To cancel the mode, perform the procedure for ID code registration again
and turn the engine switch off before driving.
●
If the change wheel set mode is canceled, the ID codes that have already been regis-
tered are communicated. When communication is finished, the tire pressure warning
light will turn off.
■
When ID code registration has failed
●
Registration may take long time or the ID codes may not be registered in the following
situations.
• When the vehicle is moved 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 transmit-
ters.
• If tire pressure warning valves and transmitters are in the vehicle.
The ID codes may not be registered.
●
When performing registration, drive on a paved road if possible. Depending on the
driving environment and condition of the tires, registration will be completed in approx-
imately 10 to 30 minutes.
• If registration is not complete after driving approximately 30 minutes, continue driv-
ing for a while.
• If registration is not complete after driving approximately 1 hour, park the vehicle in a
safe place for approximately 20 minutes. Then drive straight (with occasional left
and right turns) at approximately 25 mph (40 km/h) or more
*
for approximately 10
to 30 minutes.
If registration is still not complete, have the vehicle inspected by your Lexus dealer.
*
: Except when making a left/right turn
●
When the tire pressure warning light does not blink slowly 3 times, the ID code will not
be registered and the system will not operate properly. Perform registration again.
