sitting in the seat.

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 pos-
sible.
Electric power steering system warning light (warning buzzer)
■
When the battery charge becomes insufficient or the voltage temporarily drops, the electric
power steering system warning light may come on and the warning buzzer may sound.
■ Tire pressure warning light
When a malfunction occurs in the tire pressure warning system, the tire pressure warning
light blinks to warn the driver. However, if the warning light blinks for 1 minute, and then
remains illuminated, making it difficult to determine whether the warning light was blinking
initially, turn the engine switch from off to ON and check if the warning light blinks.

When the tire pressure warning light comes on

■
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire pres-
sure warning reset switch will not turn off the tire pressure warning light.
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
and tire inflation pressure changes caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).
