Emergency Trunk Release Handle
2-12
Notice: Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located on the inside of the trunk lid. This handle
will glow following exposure to light. Pull the release
handle and push the trunk lid open from the inside
to open the trunk.
