What does economy mode activated mean on a Citroen Picasso?

When "economy mode activated" appears on a Citroën Picasso, it indicates that the vehicle has entered a fuel-saving mode to conserve energy. This typically happens when the battery voltage drops below a certain level, leading to the temporary disabling of non-essential electrical functions, such as air conditioning and certain interior lights. The car aims to preserve battery power for essential systems, ensuring the engine can still start and operate efficiently. To exit economy mode, the vehicle's battery must be charged sufficiently, often requiring a short drive or charging.
