1
Before driving
IS250/220d/200d_EEInsert the mechanical key into
the cylinder and rotate to the
“OFF” position.
The “OFF” indicator turns on.
(Only when the “ENGINE
START STOP” switch is in
IGNITION ON mode.)
“PASSENGER AIRBAG” indicator information
If any of the following problems occurs, it is possible that there is a mal-
function in the system. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Neither “ON” nor “OFF” comes on.
The indicator does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.
CAUTION
When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as long
as the airbag manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which
may result in serious injury or even death.

• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)

Do not put unevenly weighted objects on the seat and do not stick sharp
objects (needles, nails, etc.) into the seat.
