Amerigon said its actively heated and cooled Climate Control Seat system is available as an option in the front seats of the 2009 Infiniti G Convertible, which is expected in showrooms this summer. Amerigon said the system is independent of the automobile's heating and air conditioning system and does not reduce power available to the engine. Other Nissan vehicles that also offer CCS include the Infiniti M35/M45, Infiniti FX35/FX50, Nissan Maxima, Nissan Cima and Nissan Fuga.
