581-1. For safe use
IS300h_EE(OM53C61E)
■Po p U p H o o d p re c a u t i o n s
●Before scrapping your vehicle, make sure to contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
●The Pop Up Hood system cannot be reused once it has operated. Have it replaced by
any authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
■Conditions under which the Pop Up Hood may not operate properly
The Pop Up Hood may not operate properly under the following conditions:
●If a pedestrian collides with the right or left corner of the front bumper or the side of the
vehicle. As such impacts may be difficult to detect, the system may not operate.
●If the vehicle speed is not detected correctly, such as if the vehicle is sliding sideways,
the system may not operate properly.
■Conditions under which the Pop Up Hood may not operate
The Pop Up Hood may not operate in the following situations:
●Colliding with a lying pedestrian
●A frontal impact applied to the front bumper while driving at speeds outside of the
operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situations, the Pop Up Hood may operate.)
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate properly if
the hood is not fully closed.
●Make sure that all 4 tires are of the specified size and inflated to the specified tire
pressure (→P. 568). If tires of a different size are used, the system may not operate
properly.
●If something has hit the area around the front bumper, the sensors may be damaged
even if the Pop Up Hood has not operated. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so may
cause accidental operation or prevent the system from operating properly. If repair or
replacement is necessary, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●Do not remove such components as the front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system from oper-
ating properly.
●Do not install anything to the front bumper or hood, as doing so may prevent the sen-
sors from detecting an impact correctly and prevent the system from operating prop-
erly.
●Do not close the hood with force or apply load to the lifters, as doing so may damage
the lifters and prevent the system from operating properly.
●Do not modify the suspension, as changes made to the vehicle height may prevent
the system from operating properly.

841-2. Hybrid system
IS300h_EE(OM53C61E)
There is an air intake vent on the right
side of the rear seatback for the pur-
pose of cooling the hybrid battery
(traction battery). If the vent becomes
blocked, the hybrid battery may over-
heat, leading to a reduction in hybrid
battery output.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
A message is automatically displayed when a malfunction occurs in the hybrid
system or an improper operation is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.

IS300h_EE(OM53C61E)
■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 power 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.
