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.

TOWING THE VEHICLE
Procedure for having your vehicle
towed or for towing another vehicle
using a removable towing eye.
Access to the tools
The tools are located under the boot
fl oor.
To gain access to them:

 open the boot,

 lift up the fl oor,

 detach and remove the holder
containing the tools. Towing your vehicle

 On the front bumper, unclip the
cover by pressing at the top left
and pulling at the right.

 Screw the towing eye in fully.

 Attach the towing bar.

 Switch on the hazard warning
lamps on the towed vehicle.

 Place the gear lever in neutral
(position N on the electronic
gearbox or automatic gearbox). Towing another vehicle

 On the rear bumper, unclip the
cover by pressing at the bottom
at pulling at the top.

 Screw the towing eye in fully.

 Attach the towing bar.

 Switch on the hazard warning
lampson the towed vehicle.
Failure to observe this special con-
dition could result in damage to
certain braking components and
the absence of braking assistance
the next time the engine is started. When towing with all four wheels on
the ground, always use a towing bar.
When towing with only two wheels
on the ground, always use profes-
sional lifting equipment.
When towing with the engine off,
there is no longer any braking or
steering assistance.

TOWING A TRAILER,A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer. If the trailer is not fi tted by a
CITROËN dealer, it is imper-
ative that it is fi tted using the
electrical pre-equipment installed at
the rear of the vehicle, in accordance
with the manufacturer's instructions.
Driving advice
Distribution of loads


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
towing load must be reduced by
10 % and so on for every 1 000 me-
tres of altitude.
Refer to the "Technical Data" section
for details of the weights and towing
loads which apply to your vehicle.
Side wind

 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.

 To lower the engine speed, reduce
your speed.
The maximum towing load on a long
slope depends on the gradient and
the ambient temperature.
In all cases, pay attention to the
coolant temperature.

 If 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 brak-
ing distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.
Lighting

 Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer. Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be particu-
larly careful.

ROOF BARS
The design of your vehicle requires
the use of roof bars and roof box-
es that are tested and approved by
CITROËN, for your safety and to avoid
damage to the roof and tailgate
Regardless of the type of loading
equipment to be transported on the
roof (roof box, bicycle carrier, ski
carrier...), it is imperative that you
add transverse roof bars.
Recommendations

 Distribute your load evenly, avoid-
ing overloading on one side.

 Arrange the heaviest part of the
load as close as possible to the
roof.

 Anchor the load securely and
signal if any part of it is over-
hanging.

 Drive gently, as the vehicle will
be more liable to the effects of
side winds (vehicle stability may
be altered).

 Remove the roof bars as soon
as they are no longer needed. Bicycle carrier
The installation of a bicycle carrier
on the tailgate of the 3-door model is
strictly prohibited.
Maximum load that can be dis-
tributed on the roof bars (for a
loading height not exceeding
40 cm; except bicycle carrier): 80 kg.
If the height exceeds 40 cm, adapt
your speed to the profi le of the road
to avoid damaging the roof bars
and the fi xings on the roof.
Please refer to national legislation
in order to comply with the regula-
tions concerning the transportation
of objects which are longer than
the vehicle.
* According to country.
VERY COLD CLIMATE SCREEN *
Removable device which prevents
the accumulation of snow at the ra-
diator cooling fan.
Fitting

 Offer up the very cold climate
screen to the front of the lower
section of the front bumper.

 Press on its periphery to clip its
fi xing clips one by one.
Removal

 Use a screwdriver as a lever to
unclip each fi xing clip in turn.
Do not forget to remove the very
cold climate screen:
- when the outside temperature exceeds 10 °C,
- when towing,
- at speeds higher than 75 mph (120 km/h).
