Our test car was fitted with the optional Bowers & Wilkins 440W sound system which features Dolby Pro Logic II surround sound through an array of 14 speakers.
From the steering wheel you can control the audio system and the adaptive cruise control preferences. Our Jaguar XF test car was fitted with the optional Adaptive Cruise Control (ACC with Advanced Emergency Brake Assist £973.83 option) that utilises microwave radar technology to monitor the road ahead and automatically reduces speed if traffic conditions make it necessary. It normally reduces speed simply by reducing power, but if necessary (for instance if another car pulls sharply into your path on a Motorway) it will also use the brakes to slow down more quickly. The gap to the vehicle in front is based on time, so as your speed increases, so does the gap. It is possible to manually adjust the gap to three levels using the steering wheel control; ultimately we weren't too happy with the length of the gap.
The Adaptive Cruise Control package includes Forward Alert which warns you of potential collisions. When approaching another vehicle or other obstacle it continuously estimates the braking effort required to avoid it. If the distance available falls below the safe threshold, Forward Alert sounds an audible warning prompting the driver to take appropriate action. We are not too sure why but when the Forward Alert system is engaged an irritating warning light is displayed on the dashboard.
InfotainmentOur test car was fitted with the optional Bowers & Wilkins 440W sound system which features Dolby Pro Logic II surround sound through an array of 14 speakers. Plus there is the Portable Audio Interface which allows simple, direct connection of iPod, MP3 and USB players with full control via the Touch-screen or steering wheel controls. It allows full control over the iPod, including charging - you even get a Jaguar logo on your iPod which we rather liked. If you prefer CDs then there is 6 disc in dash auto-changer.
Our test car was also fitted with a Digital Audio Broadcasting (DAB) radio tuner which had mixed reception, whilst touring across the UK. We also benefited from the optional analogue/digital TV tuner, which sensibly only works when stationary.
The touch screen DVD Satellite Navigation system includes full post code destination entry and TMC which can automatically recalculate your route and warn you of delays such as accidents or road works on your planned route.
