■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. 679). 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

●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.

WARNING
• When an object is directly under a bumper • When objects become too close to the sensors• When a non-genuine Lexus suspension (l owered suspension, etc.) is installed
In addition to the situations above, there are instances in which, because of their shape, signs and other objects may be judged by th e sensor to be closer than they are.
●The shape of an object may prevent the sensor from detecting it. Pay particular atten-
tion to the following:
• Wires, fences, ropes, etc. • Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects •Low objects• Tall objects with upper sections projecting outwards in the direction of your vehi-
cle • People, animals and other moving objects• People wearing certain types of clothing
●The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance
may be shortened, or detection may not be possible. • Objects may not be detected if they are too close to a sensor.• There will be a short delay between the de tection of an object and display of the
detection. Even at slow speeds, there is a possibility that the object will come within a sensor’s detection area before the display is shown and a warning beep sounds.
• Thin posts or objects lower than a sensor may not be detected when approached, even if they have been detected once.• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.
