Front passenger detection sensor, seat belt reminder and warning buzzer
●
If luggage is placed on the front passenger seat, the front passenger detection sen-
sor may cause the warning light to flash and the warning buzzer to sound even if a
passenger is not sitting in the seat.
●
If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
■
If the malfunction indicator lamp comes on while driving
First check the following:
●
Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●
Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.
