BATTERY

Procedure for charging your battery

when it is ﬂ at or for starting the en-

gine using another battery.

Access to the battery



secure the bonnet strut,



Do not force the plate as locking will

not be possible of the clip is posi-

tioned incorrectly.

Start the procedure again.

Starting using another
battery

 Connect the red cable to the

positive terminal (+) of the ﬂ at

battery A , then to the positive ter-

minal (+) of the slave battery B .



Connect one end of the green or

black cable to the negative ter-

minal (-) of the slave battery B .

 Connect the other end of the

green or black cable to an earth

point C on the broken down

vehicle.



Operate the starter, let the engine

run.



Wait until the engine returns to

188

P R A C T I C A L I N F O R M A T I O N

The batteries contain harm-

ful substances such as sul-

phuric acid and lead. They

must be disposed of in accordance

with regulations and must not, in

any circumstances, be discarded

with household waste.
Take used remote control batteries

and vehicle batteries to a special

collection point.

It is advisable to disconnect the

battery if the vehicle is to be left

unused for more than one month.

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.

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:

- the remote control key,

- the one-touch electric windows,

- the glass panoramic roof shutter,

- the settings of the multifunction

screen,

- the audio equipment radio stations,

- the GPS satellite navigation

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.

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, wind-

screen wipers, dipped headlamps,

courtesy lamps, 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-function

screen indicating that the vehicle has

switched to economy mode and the

active functions are put on standby.

If the telephone is being used at this

time:

- it will be maintained for 10 minutes

with your Audio system hands-free

kit,

- it will be maintained for 10 min-

utes with the NaviDrive, then it

will transfer to your telephone

depending on its model.

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 engine

and let it run for at least 5 minutes.

A ﬂ at battery prevents the

engine from starting (refer

to the corresponding para-

graph).
