Practical information -> Load reduction mode for Your Citroen Ds4 SUV First Generation (2010-2018)

Load reduction mode Energy economy mode  
System which 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,  
the heated rear screen...  
System which manages the period of use of certain functions to conserve a sufficient level of  
charge in the battery.  
After the engine has stopped, you can still use functions such as the audio equipment, windscreen  
wipers, dipped beam headlamps, courtesy lamps, etc. for a maximum combined period of thirty  
minutes.  
This period may be greatly reduced if  
the battery is not fully charged.  
The deactivated functions are reactivated  
automatically as soon as conditions permit.  
Switching to economy mode Exiting economy mode  
Once this period has elapsed, a message  
appears in the screen indicating that the  
vehicle has switched to economy mode and the  
active functions are put on standby.  
These functions are reactivated automatically  
the next time the vehicle is driven.  
In order to resume the use of these  
functions immediately, start the engine and  
let it run for a few minutes.  
The time available to you will then be double  
the period for which the engine is left running.  
However, this period will always be between  
five and thirty minutes.  
If the telephone is being used at the  
same time on the navigation system,  
it will be interrupted after 10 minutes.  
A flat battery prevents the engine from  
starting (refer to the corresponding  
paragraph).
