Question: What is the square button on the door handle of the 300?

Posted in Uncategorized by wolferadio11 on February 24, 2010

Answer:
It is the sensor for the Passive Entry/Keyless Go system.
With the Passive Entry System a consumer can gain access to their vehicle as long as they have the key fob on their person, pocket or purse.  When a consumer approaches the vehicle and grabs the driver’s door handle, the sensor on the handle will automatically sense their presence and unlock the door without the consumer having to remove/use their key fob to unlock the door.
