The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. As the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the occupants.
When the Pop Up Hood is activated, a non-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: →P. 5 4 )

541-1. For safe use
IS250_EE(OM53C51E)
When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meets or exceeds the threshold level while
the vehicle is being driven within the operational speed range, the system
becomes operational and raises the rear portion of the hood.
Sensors

Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the Pop Up
Hood system raises the rear portion of the hood to reduce the possibility of a
serious impact to the pedestrian’s head area by adding clearance to the
engine compartment.

■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. 546). 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.
