ENERGY ECONOMY MODE
System which manages the duration
of use of certain functions to con-
serve a suffi cient level of charge in
the battery.
After the engine has stopped, you can
still use functions such as the audio
and telematics system, windscreen
wipers, dipped headlamps, courtesy
lights, etc. for a maximum combined
duration of thirty minutes. Switching to economy mode
Once the thirty minutes are over, a
message appears on the multi-func-
tion screen indicating that the vehicle
has switched to economy mode
and the active functions are put on
standby.
Exiting economy mode
These functions are reactivated au-
tomatically next time the vehicle is
driven.
In order to resume the use of these
functions immediately, start the en-
gine and let it run:
- for less than ten minutes to use
the equipment for an equivalent
duration,
- for more than ten minutes to use the equipment for approximately
thirty minutes.
A fl at battery prevents the
engine from starting (refer
to the corresponding para-
graph).
Following reconnection of the
battery
Following reconnection of the bat-
tery, switch on the ignition and wait
1 minute before starting to permit
initialisation of the electronic sys-
tems. However, if slight diffi culties
are encountered following this oper-
ation, contact a CITROËN dealer.
Referring to the corresponding sec-
tion, you must yourself reinitialise
(depending on equipment):
- the remote control key,
- the one-touch electric windows,
- the settings of the multifunction
screen,
- the audio equipment radio sta- tions,
- the GPS satellite navigation system.
Do not disconnect the ter-
minals while the engine is
running.
Do not charge the batteries without
disconnecting the terminals fi rst.
Do not push the vehicle to start the
engine if it is fi tted with a 6-speed
electronic gearbox system.
Before disconnecting
the battery
Wait 2 minutes after switching off
the ignition before disconnecting
the battery.
Close the windows and the doors
before disconnecting the battery.
