Pop Up Hood
In the event of a frontal collision 
with a body, such as a pedestrian, 
the Pop Up Hood system raises the 
hood to reduce the possibility of a 
serious impact to the pedestrian’s 
head area by adding clearance to 
the engine compartment.
When the sensors located at the 
back of the front bumper detect a 
frontal impact with a body, such as a 
pedestrian, which meets or 
exceeds the threshold level while 
the vehicle is bein g driven within 
the operational speed range, the 
system operates.
