Description

The Standard Ignition SIA4 is a shift interlock actuator designed to provide precise control and safety for compatible Mercedes-Benz CL and S-Class models. This actuator ensures smooth gear shifting by preventing unintended gear changes, enhancing vehicle safety.

The SIA4 prevents the gear shifter from moving out of park unless the brake pedal is depressed, which is critical for safe vehicle operation. This part is a direct replacement, ensuring accurate fitment with no modifications needed.
