Before doing any work on your vehicle,
switch off the ignition ( Ready
lamp off)to avoid any risk of injury resulting fromautomatic operation of the engine. Y
our vehicle is fitted with a conventional 12 V
battery, located under the bonnet, in addition
to the hi
gh voltage battery used by the hybrid system.
In cer tain conditions, if the 12 V battery is
too discharged to activate the hybrid system, recharging from another conventional 12 V battery is possible.
Do not carry out this recharge if the Readylamp is on. Procedure
for star ting the engine using another battery or charging a discharged battery.



Disconnecting the (+) cable

221Practical information

After refitting the battery, the Stop &Start system will only be active after several hours depending on the climaticconditions and the state of charge of the battery (up to about 8 hours). When
your vehicle's battery is discharged, the engine can be star ted using a slave battery(external or on another vehicle) and jump leadcables.
Starting using another
battery


First check that the slave battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery. Do not try to star t the engine byconnecting a battery charger.
Do not disconnect the (+) terminal when the engine is running.
)Connect the red cable to the positive
terminal
(+) of the flat battery A , then to the positive terminal (+) of the slave battery B.)Connect one end of the green or blackcable to the negative terminal (-) of the slave battery B
(or ear th point on the other
vehicle).)Connect the other end of the green or black cable to the ear th point Con the broken
down vehicle (or on the engine mounting).)Star t the engine of the vehicle with the good
battery and leave it running for a few minutes.
) Operate the star ter on the broken down
vehicle and let the engine run
.
If the engine does not star t straight away, switch off the ignition and wait a few
moments before trying again.) Wait until the engine returns to idle then
disconnect the jump lead cables in the reverse order.
) Disconnect the battery from the vehicle.)
Follow the instructions for use provided by
the manufacturer of the charger. ) Connect the battery starting with the negative terminal (-).)
Check that the terminals and connectors
are clean. If they are covered with sulphate (whitish or greenish deposit), remove themand clean them.











Charging the battery using
a battery charger

Load reduction mode
System which manages the use of certainfunctions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates cer tain functions, such as the air conditioning,
the heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Do not attempt to charge the highvoltage battery.
The batteries contain harmful substancessuch as sulphuric acid and lead. They must be disposed of in accordancewith 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 batteryif the vehicle is to be left unused for more than one month.
Do not reverse the polarity and use only
a 12 V charger.Do not disconnect the terminals while the engine is running. Do not charge the batteries withoutdisconnecting the terminals first.

Do not push the vehicle to star t the
engine if the vehicle is fitted with theelectronic gearbox.







Before disconnecting the battery

Wait 2 minutes after switching off the ignitionbefore disconnecting the battery.
Close the windows and the doors before
disconnecting the battery.

Following reconnection of thebattery

Following reconnection of the battery, switch on
the ignition and wait 1 minute before star ting to
permit initialisation of the electronic systems.However, if problems remain following this
operation, contact a CITROËN dealer or aqualified workshop.
Referring to the corresponding section, you mustyourself reinitialise (depending on version):


- the remote control key,

- the electric blind(s), - ...

223Practical information
System which manages the duration 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 andtelematics system, windscreen wipers, dipped
beam headlamps, cour tes
y lamps, etc. for a maximum combined duration of aboutforty minutes.






Energy economy mode
Switching to economy
mode

A message then appears in the instrument panel screen indicating that the vehicle has
switched to economy mode and the active functions are put on standby.
If a telephone call is being made at this time,it will be maintained for around 10 minutes with
the Bluetooth hands-free system of your audio
system.


Exiting economy mode

These functions are reactivated automatically
next time the vehicle is driven.) In order to resume the use of thesefunctions immediately, star t the engine and
let it run:
- for less than ten minutes, to use theequipment for approximately five minutes,
- for more than ten minutes, to use theequipment for up to approximately thir ty minutes.

Let the engine run for the duration specified toensure that the battery charge is sufficient.
Do not repeatedly and continuously restar t theengine in order to charge the battery.
A flat battery prevents the engine from star ting (refer to the "Battery" section).
In this energy economy mode and when starting up the hybrid system, it may take a few seconds before the Readylamp comes on.

227Practical information

We recommend the use of genuine
CITROËN towbars and their harnesses that have been tested and approvedfrom the design stage of your vehicle,and that the fitting of the towbar is
entrusted to a CITROËN dealer or aqualified workshop.
If the towbar is not fitted by a CITROËN dealer, it is imperative that it isfitted in accordance with the vehiclemanufacturer's instructions.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so that the
heaviest items are as close as possible to
t
he axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Side wind
)
Take into account the increased sensitivity
to side wind.

Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the
fan is electrically controlled, its cooling capacity is not dependent on the engine speed. )
To lower the engine speed, reduce your speed.
)If the warning lamp and the STOP
warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.



The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.



Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
The maximum towed load on a long incline depends on the gradient and the ambient
tem
perature.
In all cases, keep a check on the coolant
temperature.
