■“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.
●The indicator light 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 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.

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 authorized
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 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.

entry function or wireless remote control. (The door will lock again automati-
cally.)
●The hood is opened.

■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 or wireless remote control 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 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
the vehicle.
