Emergency Trunk Release Handle
Notice: The emergency trunk release handle is not
designed to be used to tie down the trunk lid or
as an anchor point when securing items in the trunk.
Improper use of the emergency trunk release
handle could damage it.
There is a glow-in-the-dark trunk release handle located
inside the trunk on the latch. This handle will glow
following exposure to light. Pull the release handle up to
open the trunk from the inside.
