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.

CAUTION
When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
push and hold the “ENGINE START STOP” switch for more than 3 sec-
onds.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. Turning the engine off while driving will not cause
loss of steering or braking control, but the power assist to these systems will
be lost. This will make it more difficult to steer and brake, so you should
pull over and stop the vehicle as soon as it is safe to do so.
NOTICE
To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or
IGNITION ON mode for long periods without the engine running.
When starting the engine
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
