ALL Rover 75s come standard with dual-zone climate control air-conditioning and a pollen filter. Four large face-level vents direct air to front passengers, while two under-seat vents and two centre console vents are provided for rear seat passengers. There is a six-speed fan and the dual-zone function has the ability to maintain a front passenger temperature differential of up to six degrees. The 75's heated rear window uses the car's outside temperature gauge to automatically heat the glass when the outside temperature falls below 10 degrees. Front side window demisters are offered in addition to a rear screen demister, while a surprising feature is the useful, electrically operated rear window blind.
