Practical information  
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.  
F
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 with the touch screen tablet,  
it will be interrupted after 10 minutes.  
A flat battery prevents the engine from  
starting.  
For more information on the 12 V  
battery, refer to the corresponding

Practical information  
Fitting roof bars  
As a safety measure and to avoid damaging the  
roof, it is essential to use the transverse bars  
approved for your vehicle.  
Longitudinal roof bars are fitted as  
original equipment to certain versions.  
These play a purely aesthetic role and  
transverse roof bars must not be fitted  
to these longitudinal bars.  
When fitting roof bars, use only the four fixing  
points located in the roof frame. The points are  
masked by the vehicle doors when closed.  
Remove the protective covers, levering them  
off with a screwdriver. Take care not to scratch  
the paint.  
The roof bar fixings include a stud to be fitted  
to the hole at each fixing point.  
Observe the fitting instructions and the  
conditions of use in the guide supplied with  
the bars.  
Maximum load distributed over the roof  
bars, for a load height not exceeding  
40 cm (except bicycle carriers):  
Be sure to refer to national legislation in  
order to comply with the regulations for  
transporting objects which are longer  
than the vehicle.  
-
for roof bars with pads at 90 mm:  
50 kg  
-
for roof bars with pads at 150 mm:  
80 kg.  
For more information, contact a  
CITROËN dealer or a qualified  
workshop.  
If the height exceeds 40 cm, adapt the  
speed of the vehicle to the profile of the  
road to avoid damaging the roof bars  
and the fixings on the vehicle.  
Keep the protective covers safe so that they  
can be refitted after removing the roof bars.
