■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.

■The pre-crash safety system is operational when
The PCS OFF switch is not pressed and the following conditions are met:
●Pre-crash warning:
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 15 km/h (10 mph).
●Pre-crash brake assist:
• The VSC OFF switch is not pressed.
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.
●Pre-crash braking:
• The VSC OFF switch is not pressed.
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 15 km/h (10 mph).
■Conditions that may trigger the system even if there is no danger of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or right-turn
(right-hand drive vehicles)
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears to be
directly in the vehicle’s line of travel
●When there is a metal plate in the road in front of the vehicle on a downhill slope
●When climbing a steep hill causes an overhead billboard or other metallic structure to
appear directly in the vehicle’s line of travel
●When driving under an overpass
●When an extreme change in vehicle height occurs
●When passing through certain toll gates
●When passing through a tunnel
●When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
When the system is activated in the situations described above, there is also a possibility
that the brakes will be applied with a force greater than normal.

■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When an extreme change in vehicle height occurs
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or object
in a frontal collision
●When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system
The pre-crash safety system warning light will flash and warning messages will be dis-
played. (→P. 477, 487)
