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 lon-
ger 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’ tire pressure warning valves
and transmitters.
• 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, regis-
tration will be completed in approximately 10 to 30 minutes.
• If registration is not complete after driving approximately 30 minutes,
continue driving 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 40 km/h
(25 mph) or more
*
for approximately 10 to 30 minutes.
If registration is still not complete, have the vehicle inspected by your
Toyota 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.
■
When registering ID codes
●
Initialize the tire pressure warning system after ID code registration. Ini-
tialization is disabled if the system was initialized before registration.
●
After ID code registration, the tires are hot by driving. Initialize the tire
pressure warning system after the tires become cold.
■
Canceling the change wheel set mode
●
If turning the engine switch to the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system) 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 to the “LOCK”
position (vehicles without a smart key system) or off (vehicles with a
smart key system) before driving.
●
If the change wheel set mode is canceled, the ID codes that have
already been registered are communicated. When communication is fin-
ished, the tire pressure warning light will turn off.
