In a Mercedes E-Class like the E200 available in the UAE, the child lock is primarily controlled electronically via a button on the driver's door panel, and there is a manual backup switch on the inner edge of the rear doors. The electronic button, marked with a child silhouette, allows the driver to simultaneously disable the interior door handles of both rear doors, a practical feature for Dubai's heavy traffic.
Based on data from common GCC-spec models (like the E 200 AMG Line 2024) and a 3-year total cost of ownership (TCO) scenario, the cost of using this system is negligible. The primary expense is the initial vehicle purchase, where safety packages including enhanced rear door locks and rear side airbags can add around 2,000 to 3,500 AED. The system's reliability is included in the overall warranty from the dealer. The electronic switch has a minimal direct impact on running costs, such as fuel economy, which for the E 200 with the 2.0L turbo engine typically achieves around 12.5 km/l on Special 95 fuel in mixed Dubai-Abu Dhabi highway driving, according to real-world owner reports from 2023-2024.

The RTA Dubai's vehicle safety guidelines and MOI UAE's awareness campaigns consistently emphasize the importance of using all available child safety features. For a family car used on high-speed roads like Sheikh Zayed Road, proper use of the child lock is a fundamental safety step, preventing accidental door openings during school runs or long trips in summer heat.
