Where are the hood sensors in the boot on a Mercedes clk 200 1999?

In a 1999 Mercedes CLK 200, the hood sensors, specifically the hood release and safety switch, are typically located near the latch mechanism in the front of the engine bay. To access them, you would need to open the hood and look for the sensors mounted on or near the latch assembly. If you are referring to trunk sensors, those are usually found within the trunk lid or near the trunk release mechanism. For precise locations, consulting the vehicle's service manual is recommended.
