FOCUS ON SAFETY
The XJ has a range of safety systems designed to lessen the risk of accidents and to protect both the occupants and other road users.
Because the XJ is built from aluminum and magnesium it is exceptionally rigid yet light. As a result, the car is likely to suffer less damage than a conventional steel car in an accident and its occupants will have more protection.
AIRBAGS AND SEAT SAFETY
As well as driver and passenger front airbags, the XJ has side airbags in the outer edges of the front seats and side curtain airbags that drop down from above the windows to help protect occupants in both the front and rear seats. Sensors detect the size and weight of the driver and passenger before the front airbags are deflated to help prevent injury. At the same time, the front seatbelts feature "soft landing" technology, which softens the contact with the airbag. A further safety measure in the seating is the anti-whiplash technology which moves the head restraints forward if there is an accident. All XJ models also feature an advanced Belt Minder system with Virtual Instrument display, visually showing which seats have belts in use.
ADAPTIVE CRUISE CONTROL
When the optional Adaptive Cruise Control is switched on, a microwave radar in the XJ's front bumper will sense if the vehicle in front slows down. It will then slow the XJ down to maintain a constant distance, and once the road clears it will take the car back up to the pre-set speed. The radar also operates a Forward Alert, which gives the driver an audible warning if the traffic ahead slows quickly or another vehicle moves into the same lane as the XJ.
All XJ models have anti-lock brakes, which vary the brake pressure to ensure that the wheels do not lock, and the driver can keep the steering under control, during an emergency stop. Additional brake force is produced by Emergency Brake Assist, allowing for shorter stopping distances and improved steering control. Advanced Emergency Brake Assist primes the brakes if the radar within the Adaptive Cruise Control senses an imminent collision.
BLIND SPOT MONITOR
The standard Blind Spot Monitor uses radar sensors to show an amber warning signal in the side mirror if the system detects a vehicle in the driver's blind spot.
TIRE PRESSURE MONITORING
The standard Tire Pressure Monitoring system alerts the driver through the Virtual Instruments if it detects a loss of tire pressure.
Door locks on the XJ can be either controlled remotely from the key fob or opened or locked directly from the door handle using the standard Smart Key keyless entry. The doors can be set for single point or multi-point entry, where either all doors unlock at once or only the driver's door will unlock first. The driver can also set the doors to lock automatically when the car reaches a pre-set speed. The XJ is also protected by an alarm and an engine immobilizer.
