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 taking several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
Electric power steering system warning light
■
When the battery is low or when the voltage drops temporarily, the electric power
steering system warning light may come on.
Passenger detection sensor and passenger seat belt reminder
■
If luggage is placed on the passenger seat, the passenger detection sensor may
●
cause the warning light to flash 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.
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. After
the tire inflation pressure is adjusted, it may take a few minutes for the tire pressure
warning light to go off.
The tire pressure warning light may come on due to natural causes
■
The tire pressure warning light may come on due to natural causes such as natural
air leaks or tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few min-
utes).
