Land Rover Defender: Battery monitoring system
Only start the engine if it is safe to do so. Failure to do so may lead to a collision, potentially resulting in serious injury or death.
The Intelligent Power System Management (IPSM) continuously monitors the condition of the main vehicle battery.
If excessive battery discharge occurs, the system begins to shut down non-essential electrical systems in order to protect the battery.
If the IPSM calculates that the battery's condition is not within the set parameters, there are two levels of action which can be taken. Both levels have an accompanying message on the touchscreen, and in the case of the low battery warning, in the instrument panel.
- Energy Management: Is displayed in
the instrument panel if the engine is
not running and system features are
causing excessive battery discharge.
After 3 minutes, the IPSM begins shutting down the vehicle's systems.
Normal system operation resumes when the engine is started.
- Low battery - Please start engine: Is displayed on the touchscreen and in the instrument panel, if the engine is not running. After 3 minutes, the IPSM begins shutting down the vehicle's systems. Normal system operation resumes when the engine is started.
Note: If the instrument panel displays Low Battery - Please Start Engine, drive the vehicle to allow the battery to recover to an acceptable level. Drive the vehicle for at least 30 minutes in temperatures above 32ºF (0ºC), or at least 60 minutes if the temperatures are below 32ºF (0ºC). If normal system operation does not resume when the engine is switched back off, the battery may not have been sufficiently charged. If safe to do so, restart the engine. If problems still exist, contact a retailer/authorized repairer.
