Charging the battery using
a battery charger
F Disconnect the battery from the vehicle.
F Follow the instructions for use provided by
the manufacturer of the charger.
F Reconnect starting with the negative
terminal (-).
F Check 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.
Some functions are not available if the
battery is not sufficiently charged.
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 after wards.
It is advisable to disconnect the battery
if the vehicle is to be left unused for
more than one month.
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.
d
o not push the vehicle to start the
engine if your vehicle has an automatic
gearbox.
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).

Energy economy mode
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.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:
- for less than ten minutes, to use the
equipment for approximately five minutes,
- for 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

Access to the tools
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:
- vehicle broken down on a motor way or fast road,
- four-wheel drive vehicle,
- when it is not possible to put the gearbox into neutral, unlock the steering, or release
the parking brake,
- towing with only two wheels on the ground,
- where there is no approved towing arm available...

Towing a trailer
Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Side wind
F Take into account the increased sensitivity
to side wind.
Driving advice
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 To 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.
We recommend the use of genuine
CITROËN towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITROËN dealer or a
qualified workshop.
If the towbar is not fitted by a
CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care.
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 per formance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
F If the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.

Blanking cover
When towing, you must remove the blanking
cover in the front bumper as well as the bonnet
seal if fitted.
Contact a CITROËN dealer or a qualified
workshop for this.
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.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
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.
