This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive belt.
If it is loose or broken, the generator will not charge the battery
properly.
If the belt is O.K., there is a problem somewhere in the charging
system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower, radio,
etc., and drive directly to the nearest Lexus dealer or repair shop.

Side airbags
Side airbags:
In response to a severe side impact, the side airbag for the driver
or front passenger works together with the seat belt to help
preventing or reducing injury by inflating, in order to decrease
the impact mainly on the driver or front passenger’s chest.
The side airbag on the passenger seat is activated even with no
passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with considerable force. To avoid
potential death or serious injury during inflation of a side
airbag, Lexus strongly recommends that the driver and front
passenger;
Wear their seat belt.
Remain properly seated with their back against the seat at
all times.
16L136-2
The indicator comes on when the ignition key is turned to the
”ACC” or ”ON” position. It goes off after about 6 seconds. This
means the SRS is operating properly.

Driver and front passenger airbag sensor assembly
The SRS airbag sensor assemblies consist of a safing sensor and
driver and front passenger airbag sensor.
In a severe frontal impact, the driver and front passenger airbag
sensor detects deceleration and the system triggers the front airbag
inflators and seat belt pretensioners. In a severe side impact, the side
airbag sensor triggers the side airbag inflator. Then a chemical
reaction in the inflators momentarily fills the airbags with nontoxic
gas to help restrain the forward or lateral motion of the occupants.
Then the inflators fill the airbags and the seat belts are quickly drawn
back in by the retractors to help restrain forward motion of the
occupants.
When the SRS operates, it produces a fairly loud noise and release
