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. 56)
WARNING
■SRS airbag precautions
Observe the following precaution s regarding the SRS airbags. Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driv er is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation, placing yourself 250 mm (10 in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to your breastbone. If you sit less than 250 mm (10 in.) away now, you can change yourdriving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com- fortably.• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis- tance, even with the driver seat all the way forward, simply by reclining the back ofthe seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle has that feature.• If your steering wheel is adjustable, tilt it downward. This points the airbag toward
your chest instead of your head and neck. The seat should be adjusted as recommend ed above, while still maintaining control of the foot pedals, steering wheel, and your view of the instrument panel controls.

RC300h_EE(OM24740E)
When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meet s 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
Hood
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 he ad area by adding clearance to the
engine compartment.

■Pop Up Hood precautions
●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 prop erly 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 difficul t 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 wh ich 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 specif ied size and inflated to the specified tire
pressure ( P. 604). 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 anothe r 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 sy stem from operating properly. If repair or replacement is necessary, contact any authorized Lexus dealer or repairer, oranother duly qualified an d 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.
