CAUTION
When installing a child restraint system
For safety reasons, always install a 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.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases
if inhale.
CAUTION
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an
accident caused by light-headedness, or may lead to death or a serious health
hazard.
Important points while driving
Keep the trunk lid closed.
If you smell exhaust gases in the vehicle even when the trunk lid is closed,
open the windows and have the vehicle inspected at any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
When parking
If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.

GS350/250_EE (OM30C36E)
Engine immobilizer system
The indicator light flashes after
the engine switch has been
turned off to indicate that the
system is operating.
The indicator light stops flashing
after the engine switch has been
turned to ACCESSORY or
IGNITION ON mode to indicate
that the system has been can-
celed.
System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
Conditions that may cause the system to malfunction
If the grip portion of the key is in contact with a metallic object
If the key is in close proximity to or touching a key to the security system
(key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the
engine from starting if a key has not been previously registered in
the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.

GS350/250_EE (OM30C36E)
Alarm
The alarm uses light and sound to give an alert when an intrusion is
detected.
The alarm is triggered in the following situations when the alarm is
set:
A locked door is unlocked or opened in any way other than using
the entry function or wireless remote control. (The door will lock
again automatically.)
A trunk is opened in any way other than using the entry function,
wireless remote control or mechanical key.
The hood is opened.
The tilt sensor detects a change of vehicle inclination. (if
equipped)
Close the doors, trunk and hood,
and lock all the doors using the
entry function or wireless remote
control. The system will be set
automatically after 30 seconds.
The indicator light changes from
being on to flashing when the sys-
tem is set.

Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
The alarm will still be set even when the intrusion sensor and tilt sensor are
canceled.
After the intrusion sensor and tilt sensor are canceled, pressing the engine
switch or unlocking the doors using the entry function, wireless remote con-
trol or mechanical key will re-enable the intrusion sensor and tilt sensor.
The intrusion sensor and tilt sensor will automatically be re-enabled when
the alarm system is deactivated.
Intrusion sensor detection considerations
The sensor may trigger the alarm in the following situations:
Places with extreme vibrations or noises, or situations in which the vehicle
is subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
A window or the moon roof is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside the
vehicle
• Ultrasonic waves emitted from
devices such as the intrusion sensors
of other vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.
