Land Rover Defender: Battery and Charging System - General Information

SPECIFICATIONS

Startup battery

Startup battery disconnect/connect

CAUTIONS:

• The vehicle status and start up battery condition must be established before attempting battery disconnect /connect. Reference must then be made to the following table to establish the relevant procedure to be followed.
• After connecting the start up battery, the steering wheel must be turned to full left-hand and full right-hand lock with the engine running. This allows the dynamic stability control system to calibrate the steering wheel position. Failure to follow this instruction may result in a variety of Instrument Panel Cluster (IPC) warning lamps being illuminated.

NOTES:

• If there is insufficient capacity in the startup battery to disarm the alarm, the alarm may sound on connection of the startup battery - turning the ignition key to position II will disarm the alarm.
• If a new startup battery is installed, the startup Battery Monitoring System (BMS) must be reset using Jaguar Land Rover approved diagnostic equipment.

WARNINGS:

• Take care when working near rotating parts of the engine.
• Prior to attempting to start the disabled vehicle, make sure that the parking brake is applied or suitably chock the wheels. Make sure that 'P' - PARK - Automatic Transmission or NEUTRAL - Manual Transmission is selected.
• Suitable eye protection must be worn when working in the vicinity of the battery.

CAUTIONS:

• Make sure that there is no physical contact between the donor and disabled vehicles other than the booster cables.
• Make sure that the slave battery/starting aid is of the 12 volt type.
• Make sure that all electrical systems and ignition are switched OFF prior to connecting the booster cables.
• Disconnect the booster cables prior to operating any electrical systems.
