The Infiniti EX was the first production automobile to offer a surround-view camera, marketed as Around View Monitor. The cameras are located at the front, back and sides of the vehicle and feed images to an image processing unit; those individual inputs are analyzed, synthesized to offer a synthetic but positionally accurate top-down view of the car and its surroundings. The image appears in lifelike detail.[8][9]

• The EX is also one of the first production automobiles to feature "Scratch Shield," a "self-healing clearcoat paint. The paint self-repairs fine scratches, such as fingernail scratches under door handles, restoring the EX's surface close to the original state. The process, which takes anywhere from one day to one week (depending on the surrounding temperature and the depth of the scratch), is accomplished through the use of an elastic resin. It is combined with a conventional clearcoat to increase the paint's flexibility and strength by raising the resin density."[3]
• The EX becomes the second Infiniti production vehicle, following the 2008 Infiniti M series, to offer the Lane Departure Prevention (LDP) system.[10] This utilizes the electronic stability control system to help assist the driver in maintaining lane position by applying gentle brake pressure on each wheel individually to generate intended movement. It sounds an alert and nudges the vehicle in the correct direction when lane departure is detected.[11] It also applies braking actuation to bring vehicle back in the lane.[10]
