Warning performance of the tire pressure warning system
■
The warning of the tire pressure warning system will change in accordance with the con-
ditions under which it was initialized. For this reason, the system may give a warning even
if the tire pressure does not reach a low enough level, or if the pressure is higher than the
pressure that was adjusted to when the system was initialized.
When initialization of the tire pressure warning system has failed
■
Initialization may take longer to complete if the vehicle is driven on an unpaved road.
When performing initialization, drive on a paved road if possible. Depending on the driv-
ing environment and condition of the tires, initialization will be completed in approxi-
mately 10 to 30 minutes. If initialization is not complete after driving approximately 10 to
30 minutes, continue driving for a while.
If the inflation pressure of each tire is not displayed after driving for approximately 1 hour,
perform the following procedure.
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.
However, in the following situations, the tire inflation pressure will not be recorded and
the system will not operate properly. Perform initialization again.
When operating the tire pressure warning reset switch, the tire pressure warning light
●
does not blink 3 times.
After performing initialization, the tire pressure warning light blinks for 1 minute then
●
stays on while driving.
If the inflation pressure of each tire is still not displayed, have the vehicle inspected by
your Lexus dealer.
