Disconnecting Battery

NOTE: Some Land Rover models may be equipped with a anti-theft alarm back-up battery. Before disconnecting main battery, turn ignition on and then off. Main battery must be disconnected within 17 seconds or anti-theft alarm will be activated using back-up battery.

Before disconnecting negative battery, obtain radio presets and anti-theft code for radio from vehicle owner. When radio is disconnected from battery power it will not operate when power is restored until anti-theft code is entered. See vehicle OWNER'S MANUAL for procedure. Other vehicle systems (if equipped) affected by disconnecting battery may be electric windows and sun roof, trip computer, trip odometer and remote security handsets. See vehicle OWNER'S MANUAL for system reset procedures before disconnecting battery.
