Rear trunk manual release system stationary vehicle tests were conducted with a passenger trapped in the luggage compartment with the lid closed. An assistant was there and ready to release the passenger if needed. The pod was evaluated by stacking it in accordance with vehicle label instructions, with all removable equipment provided by the manufacturer.

The procedure used consists of the following steps:

Identify ways for a person trapped in the trunk to escape from the compartment, eg. Pulling the T-arm release, rotating the fixed-lever release, pressing a button, etc.

For informational purposes, attach a linear force transducer to the aforementioned release mechanism and record the force that must be applied to get the trapped person to escape.

Verify that the release mechanism is visible on the darkened body S4.2(a) and identify the method used, e.g. phosphorescence or auxiliary lighting. It may take some time for the eyes to adjust to the dark environment in the luggage compartment. Take a photo of the light release mechanism if possible.

When the vehicle is stationary and the key is not in the ignition (means it is not empty)
vehicle), operate the release mechanism and verify that the tailgate is disengaged from all locking positions. Record the force required during 3 attempts to release the stem locking mechanism.

Repeat step 4 above, except when the engine is idling (time with the tailgate unlocked). to exceed 30 seconds).
