Features & Controls
Pull upward on the remote release
handle, located on the floor near the left
side of the driver's seat, to release the
trunk lid.
Lockout Feature:
The remote trunk release is equipped
with a lockout feature to help prevent
unauthorized entry into the trunk when
the vehicle is unattended. The switch is
located on the inside of the trunk lid,
mounted to the trunk lid latch.
To turn the lockout on, slide the switch
all the way to the right. To turn the
lockout off, slide the switch all the way
to the left.
When the lockout is on, the mechanical
remote trunk release will not release the
trunk lid. However, the trunk lid can
still be opened with the key.
