What does engage drivers seat indicator mean on 2009 Mercedes clk?

The "engage driver's seat indicator" on the 2009 Mercedes CLK is a warning light that will illuminate when the driver's seat is not properly engaged in the seat track. This can be a safety hazard, as the driver may not be properly secured in the event of an accident.

To engage the driver's seat properly, make sure that the seat belt latch is properly clicked shut. Then, slide the seat forward until the front edge of the seat is touching the back of the center console. Hold the seat release lever down and slide the seat back and forth until it locks securely into place.

Once the seat is properly engaged, the warning light will turn off. If the warning light does not turn off, or if you are unable to engage the seat properly, you should consult your Mercedes dealer.
