DS 3: Practical information / Energy economy mode. Load reduction mode

Energy economy mode

This system manages the duration of use of certain functions, in order to conserve a sufficient level of charge in the battery with the ignition off.

After switching off the engine, you can still use functions such as the audio and telematic system, the wipers and the dipped beam headlamps or courtesy lamps, for a combined duration of approximately 40 minutes.

Selecting the mode

A confirmation message is displayed when energy economy mode is entered, and the active functions are placed on standby.

If a telephone call is in progress at the time, it will be maintained for around 10 minutes via the audio system’s hands-free system.

Exiting the mode

These functions are automatically reactivated the next time the vehicle is used.

To restore the use of these functions immediately, start the engine and let it run:

For less than 10 minutes, to use the equipment for approximately 5 minutes.

For more than 10 minutes, to use the equipment for approximately 30 minutes.

Let the engine run for the specified duration to ensure that the battery charge is sufficient.

To recharge the battery, avoid repeatedly or continuously restarting the engine.

A flat battery prevents the engine from starting.

For more information on the 12 V battery/Accessories battery/, refer to the corresponding section.

Load reduction mode

This system manages the use of certain functions according to the level of charge remaining in the battery.

When the vehicle is being driven, the load reduction function temporarily deactivates certain functions, such as the air conditioning and the heated rear screen.

The deactivated functions are reactivated automatically as soon as conditions permit.
