■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the sys-
tem. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●Neither “ON” nor “OFF” comes on.

to “ON” or “OFF”.
CAUTION
■When installing a child restraint system
For safety reasons, always install a child rest raint 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.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or falling object
Pop Up Hood operational conditions
CAUTION
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the hood and may cause an injury.
Do not drive with the hood raised, as doing so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by
hand, doing so may deform the hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional. If the
Pop Up Hood has operated, stop the vehicle in a safe place and contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift-
ers may be hot and burn you.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
CAUTION
Exhaust gases include harmful carbon monoxi de (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
hybrid system.
●Do not leave the vehicle with the hybrid system 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 hybrid system operating in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, 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.

IS300h_EE(OM53D56E)
■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”
indicator does not come on, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (→P. 5 2 3 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The minimum amount of fuel to add to make the low fuel level warning light go out is
about 10 L [2.7 gal., 2.2 Imp. gal.], when the vehicle is on a level surface. This value may
vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery
electric vehicle safety).

cate that the system has been canceled.
■System maintenance
The vehicle has a maintenance-free type 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 registered to the security system (key
with a built-in transponder chip) of another vehicle
Immobilizer system
The vehicle’s keys have built-in transp onder chips that prevent the hybrid sys-
tem 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.
This system is designed to help prev ent vehicle theft but does not guarantee
absolute security against all vehicle thefts.

961-3. Theft deterrent system

●A locked door or trunk is unlocked or opened in any way other than using the
entry function or wireless remote control. (The door will lock again automati-
cally.)
●The hood is opened.
●The intrusion sensor detects something moving inside the vehicle. (An
intruder gets in the vehicle.) (if equipped)
●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 func-
tion or wireless remote control. The
system will be set automatically after

the intrusion sensor and tilt sensor.
●The intrusion sensor and tilt sensor will au tomatically be re-enabled when the alarm
system is deactivated.
■Intrusion sensor dete ction 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 on 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 follow-
ing:
• 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 vehi-
cles
• The movement of people outside the vehi-
cle
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in
