Avoid using ignition mode II as much as posssible, or electrical functions that require a great deal of electrical current when the engine is not running.
Using ignition mode I whenever possible consumes less electrical current.
Functions that require a great deal of electrical current include:
- the climate system blower
- headlights
- wipers
- infotainment system (especially at high volume).
If the battery's charge level is low, a text message will appear in the instrument panel. The vehicle's energy-saving function will then turn off or reduce certain functions that are currently consuming electrical current.
If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes or drive the vehicle (driving charges the battery faster than letting the engine idle).
