Car trunk escape guide: Don’t let the “life passage” become a decoration

Every summer, the news of children being trapped in the trunk of a car always makes people worried. Data shows that over 60% of car owners have never checked the trunk escape device, and nearly 90% of vehicles have failed the escape function due to mechanical failures, aging wiring, and other problems. When danger comes, the trunk should be a “life channel”, but without systematic maintenance, it may become a fatal trap.

The truth about escape device failure: overlooked hidden faults

Car trunk escape devices usually consist of mechanical handles, lighting systems, and signal triggering modules. The reasons for their failure are far more complex than imagined.

Mechanical sticking: Rust of the handle spring and dust accumulation on the slide rail cause the operating resistance to double.

Circuit aging: The escape button circuit is short-circuited due to moisture, and the trigger signal cannot be transmitted to the door control system.

Hidden danger of parts replacement: Non-original locks are incompatible with the body control system protocol.

These hidden dangers are often ignored in daily maintenance, and the risks are only exposed in emergency situations. An experiment by a local fire department showed that the mean time between failure of vehicle escape devices that are not regularly serviced is only 2.3 seconds, which is 87% shorter than normal conditions.

Three-step self-examination method: survival skills that every family must learn

1. Functional test: When the vehicle is turned off, drill into the trunk to close the hatch cover, manually trigger the escape handle (usually a fluorescent handle or button), and observe whether the door automatically pops open;

2. Environmental simulation: Use a black cloth to cover the rear window to simulate the night environment and check whether the emergency lighting can last for more than 10 minutes;

3. System linkage: When the escape device is triggered, whether the double flash light starts synchronously and sends a distress signal to the vehicle intelligence system.

If any link is abnormal, the vehicle maintenance file should be immediately retrieved through the vehicle maintenance to verify whether the last three maintenance operations include key items such as lock lubrication and circuit testing.
