CAUTION
Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
When moving the support rod
High temperatures in the engine compartment cause the support rod to
become extremely hot.
When moving the supporting rod, be sure to hold the support rod cover to
prevent burns.
After installing the support rod into the slot
Make sure the rod supports the hood securely, so that it will not fall down
onto your head or body.
NOTICE
When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing
the hood with the support rod up could cause the hood to bend.
