Maintenance and care
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.
■ After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
Hold the hood open by insert-
ing the supporting rod into
either of the slots.
Use the forward slot to open
the hood normally, or use the
rearward slot when the hood
needs to be opened wide.
