			====Modification to Improve Performance of Seat Base Ventilation Fans====
			Thanks to MBWorld member RJC here's a tip to truly cool the bottom seat cushion.

			While you have the front seat removed to replace the fans with larger ones, cut a 3" (75mm) diameter hole in the top of the plastic vent that's under the seat/carpet which is there to heat/cool the feet of the back seat passenger. Then get some foam and plug the rear facing openings. These vents are easily accessible afterwards by moving the front seat as far forward as it will go, so you could try just blocking 50 - 75% of the air flow first. Then if you feel inclined, block the whole outlet later.

			When you run the AC, set it to bi-level and some of the cold air that passes under the seat will also be directed upwards and get sucked up by the fans directly into the seat bottom cushion.

			DIYers who have done this modification report that the seat cushion got so nice and chilled, everyone that tried the seat loved it!

	The idea of seat ventilation is to cool the contacted seat area by blowing air over the inside of the seat cushions (directly towards the occupant) thus removing some of the driver or passenger's body heat and reducing the 'sticky' back or behind effect which is common on a hot day. They are particularly useful if you need to wear a suit in the car on a hot day.

They are particularly useful if you need to wear a suit in the car on a hot day.

	The seat ventilation is achieved by means of an electronically controlled fans in the various seat bases and seat back rests. In the W220 there are four fans in each ventilated seat base and six fans in each ventilated seat back rest. (To be confirmed.)

	The seat base fans suck internal cabin air from under the seat and blow it over the inside of the base seat cushions (directly towards the occupant). The leather seat covers have small perforations to enhance the air flow cooling effect.

	In an attempt ~~too~~ quantify how well the OEM seat ventilation worked in a W220 S500, BenzWorld member ricebubbles measured the temperature of the seat back rests for an occupied and an unoccupied seat and with the ventilation fans off and then on their maximum setting. The back rest of the occupied seat was of course warmed by the occupant's body heat.

			Vehicles equipped with option code [[Option_codes#873_-_SEAT_HEATER_FOR_LEFT_AND_RIGHT_FRONT_SEATS\|873 - SEAT HEATER FOR LEFT AND RIGHT FRONT SEATS]]
			have seat heating feature for front seats.

			Rear seats are heated in vehicles with option code [[Option_codes#872_-_REAR_SEAT_BENCH_HEATING_LEFT_AND_RIGHT\|872 - REAR SEAT BENCH HEATING LEFT AND RIGHT]].

			Seat heating has three modes:
			* Rapid heating (two lamps on)
			* Normal heating (one lamp on)
			* No heating (lamps off)

			The system switches from the rapid heating mode to normal heating mode after approximately five minutes.
			The seat heating will be automatically switched off after approximately 30 minutes.

			additionally to the seat heating feature are equipped also with the seat ventilation feature in front and rear seats, respectively.

			The blue indicator lamps on the switch show the ventilation level selected.
			Seat ventilation can be activated manually with the SmartKey in starter switch position 1 or 2.
			The driver's seat ventilation can be activated to the highest level automatically by the summer opening feature.

			'''Note:''' If one or all of the lamps on the seat ventilation switch are flashing,
			there is insufficient voltage since too many electrical consumers are switched on.
			The seat ventilation and heating switches off automatically.
			The seat ventilation and heating will switch back on again automatically as soon as sufficient voltage is available.

			== Non Functional Heated Seats==

			The seat heater wires and the supply wires often fail due to constant flexing of over several of the rigid seat support frames.

			The complete upholstery or seat cushion is no longer replaced, reference document LI91.30-P-048345, "Heated Seats Nonfunctional."
