The new Citroën C4 is designed for business-class travel with intuitive, intelligent technology enabling owners to tailor the new C4's environment and ambience to their own preferences. For example, the intensity of the automatic dual-zone air conditioning can be set to Light, Medium or Strong, and a REST function maintains ventilation in the cabin for up to eight minutes after the engine is switched off.

With full or part-leather upholstery, the front seats on Exclusive models feature electric lumbar adjustment for maximum support and a massage function for a touch of luxury - another new feature for the segment.

The cockpit is driver-focused, with an ergonomically optimised driving position placing the instrument cluster and controls within easy sight and reach. Fusing analogue with digital display technologies, the new instruments features three striking binnacles that provide exceptional legibility of all essential driver information whilst covering the cabin in a soft blue or white glow. An aviation-inspired touch of technology, the analogue speedometer circles around the central binnacle instead of sitting at its centre. The colour of the binnacle display can be changed from blue to white to suit the driver's preference.

Acoustic treatment was a priority in the development of new Citroën C4 and the levels of soundproofing have been engineered to match those of larger executive saloons. The meticulous sonic treatment includes an acoustic laminated windscreen on most models; peripheral sealing barriers on the body and doors; and sound absorbent materials in the engine compartment. Vibration, engine noise, aerodynamic noise and road noise have all been minimised to create a calm and peaceful cabin environment.

Complementing this quiet, refined ambience, new C4's 'polyphonic' sound alerts are available with four different themes (Classic, Crystal Symphony, Jungle Fantasy & Urban Rythmik) for the indicator signals or the unfastened seatbelt warning.

Essential for a satisfying on-board experience, the new C4 is fitted with a Surround Sound audio system as standard. Alternatively, Citroën has partnered with Denon to create an optional premium HiFi system that includes four specially developed woofers, four tweeters, a digital amplifier and a sub-woofer in the boot.

As with all of the latest Citroën models, new Citroën C4 offers all the connectivity to satisfy the modern driver. A USB port, 3.5mm jack plug and 12V socket are available on the centre console for connecting, listening to and charging a range of electronic devices. Most models also feature an additional 12V port and removable torch in the boot.

The new C4 can be equipped with eMyWay - Citroën's integrated new-generation navigation system. Features include a high-resolution colour display; GPS satellite navigation; internal memory; USB connectivity for MP3 players; speed limit display; and Bluetooth® for hands free calls and audio streaming from mobile phones.

The availability of front and rear parking sensors, parking space 'gap' measurement, electric folding and heated door mirrors, an automatic electric parking brake and Hill Start Assist also make the new Citroën C4 easy to live with in built-up environments.

Available as an accessory, Citroën's WiFi On Board system uses a 3G/3G+ SIM card to create a wireless network in the car with continuous internet connection.
