3207-2. Steps to take in an emergency
■Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passenger seat, the front passenger detection sensor may
cause the warning light to flash and the warning buzzer to sound even if a passenger is not
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 af ter 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 pressu re 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 warnin g light may come on due to natural causes such as natural air leaks
and tire inflation pressure chan ges caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure wa rning system may not function properly
 P.283
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the
engine switch is turned to ON, have it checked by your Lexus dealer.

In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
