Security System

The factory integrated security system fitted in the 1994 XJS Range is derived from the system introduced in the 1993 Sedan Range.

System layout and features



The new XJS security system provides both audible and visual alarms. In addition to the standard security and convenience features, the system can be equipped with a shock sensor. The system is supplied with two radio frequency (RF) key fob transmitters.
