Access to the battery
Procedure for starting the engine using another battery or charging a discharged battery.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITROËN dealer
or a qualified workshop is essential
when replacing or disconnecting the
battery.
After refitting the battery, the Stop &
Start system will only be active after a
continuous period of immobilisation of the
vehicle, a period which depends on the
climatic conditions and the state of charge
of the battery (up to about 8 hours).
Before doing any work
Immobilise the vehicle: apply the
parking brake, put the gearbox in
neutral, then switch off the ignition.
Check that all electrical equipment is
switched off.

cable to the negative terminal (-) of the
slave battery B (or earth point on the other
vehicle).

tart the engine of the vehicle with the good
battery and leave it running for a few minutes. 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 start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal when
the engine is running.
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.
Following reconnection of the
battery
Following reconnection of the battery, switch on
the ignition and wait 1 minute before starting to
permit initialisation of the electronic systems.
However, if problems remain following this
operation, contact a CITROËN dealer or a
qualified workshop.

The batteries contain harmful substances
such as sulphuric 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.Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
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 without
disconnecting the terminals first.
Wash your hands afterwards.
It is advisable to disconnect the battery
if the vehicle is to be left unused for
more than one month.
Do not push the vehicle to start the
engine if the vehicle is fitted with the
electronic gearbox.Charging the battery using
a battery charger
F Disconnect the battery from the vehicle.
F F ollow the instructions for use provided by
the manufacturer of the charger.
F

C
onnect the battery starting with the
negative terminal (-).
F

C
heck that the terminals and connectors
are clean. If they are covered with sulphate
(whitish or greenish deposit), remove them
and clean them. With Stop & Start, the battery does not
have to be disconnected for charging.

Load reduction 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...
The deactivated functions are reactivated
automatically as soon as conditions permit.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 and telematics
system,
windscreen wipers, dipped beam
headlamps,
courtesy lamps, etc. for a
maximum combined duration of about
forty 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 restore the use of these functions
immediately, start the engine and let it run:
-

f
or less than ten minutes, to use the
equipment for approximately five minutes,
-

f
or more than ten minutes, to use the
equipment for up to approximately
thirty minutes.
Let the engine run for the duration specified to
ensure that the battery charge is sufficient.
Do not repeatedly and continuously restart the
engine in order to charge the battery.
A flat battery prevents the engine from starting
(refer to the "Battery" section).

To w i n g
General recommendations
Observe the legislation in force in your country.
Ensure that the weight of the towing vehicle is higher than that of the towed vehicle.
The driver must remain at the wheel of the towed vehicle and must have a valid driving licence.
When towing a vehicle with all four wheels on the ground, always use an approved towing
arm; rope and straps are prohibited.
The towing vehicle must move off gently.
When towing a vehicle with the engine off, there is no longer any power assistance for braking
or steering.
In the following cases, you must always call on a professional recovery service:
-
v
ehicle broken down on a motor way or fast road,
-
f

our-wheel drive vehicle,
-

w
hen it is not possible to put the gearbox into neutral, unlock the steering, or release
the parking brake,
-

t
owing with only two wheels on the ground,
-

w
here there is no approved towing arm available...
Procedure for having your vehicle towed or for towing another vehicle using a removable towing eye.
The towing eye is stowed under the boot floor,
or may be located under the front passenger
seat, depending on version.

Driving advice
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the 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 by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing 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.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer.
Refer to the "Technical data" section for details
of the weights and towed loads which apply to
your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
When not towing a trailer, remove the
quickly-detachable tow ball before
driving.
