ONLY a select few car-makers offer automatically-adjustable hydraulic suspension and the C5 makes good use of the Citroen Hydractive system by varying ride height depending on circumstances: low and road-hugging on the freeway and elevated when the going gets a little tougher. The system also assures a constant ride height regardless of load. Two petrol engines - the 2.0-litre four-cylinder and the 3.0-litre V6 - plus a 2.0-litre turbo diesel are offered in Australia. The packaging follows traditional Citroen practices by offering comfort, versatility and ease of use in terms of luggage carrying abilities. The C5 also joins the Saab 9-5 in providing twin front sunvisors on each side to shield passengers from glare through front and side windows, and also offers black panel instrument illumination to eliminate all but the most vital instruments at night. Anti-glare external rearview mirrors are another V6 bonus. The hazard lights switch on automatically at a certain rate of (dramatic) deceleration.
