• Ensure that the trunk is closed and latched before driving your
vehicle. Failure to properly latch the trunk may cause objects to fall
out or block the driver’s rear view.
The remote entry system allows you to open the trunk while the ignition
is in any position. However, if the ignition is in the on position and the
vehicle is in motion, the trunk will not open if the vehicle is moving
3 mph (5 km/h) or faster.

can open the trunk on the
convertible by using your master
key in the key cylinder between
the seat cushion located in the
back seat on the driver’s side.
