LOAD REDUCTION MODE

System which manages the use of cer-
tain functions according to the level of
charge remaining in the battery.

When the vehicle is being driven, the
load reduction function temporarily deac-
tivates certain functions, such as the air
conditioning, the heated rear screen...
The deactivated functions are reactivat-
ed automatically as soon as conditions
permit.








ENERGY ECONOMY MODE

System which manages the period of
use of certain functions to conserve a
suffi cient level of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio
equipment, windscreen wipers, dipped
beam headlamps, courtesy lamps, etc.
for a maximum combined period of thirty
minutes.

Switching to economy mode

Once this period has elapsed, a message
appears in the screen indicating that the ve-
hicle has switched to economy mode and
the active functions are put on standby.
If the telephone is being used at
the same time on the navigation
system, it will be interrupted after
10 minutes.
A fl at battery prevents the engine
from starting (refer to the corre-
sponding paragraph).


Exiting economy mode

These functions are reactivated auto-
matically the next time the vehicle is
driven.


)
In order to resume the use of these
functions immediately, start the engine
and let it run for a few minutes.
The time available to you will then be
double the period for which the engine
is left running. However, this period will
always be between fi ve and thirty minutes.

This period may be greatly re-
duced if the battery is not fully
charged.

FITTING ROOF BARS


For safety reasons and to avoid dam-
aging the roof, it is essential to use the
transverse bars approved for your ve-
hicle.

When fi tting roof bars, use only the four
fi xing points located in the roof frame.
The points are masked by the vehicle
doors when closed.
The roof bar fi xings include a stud to be
fi tted to the hole at each fi xing point.
Observe the fi tting instructions and the
conditions of use in the guide supplied
with the bars.
Maximum authorised weight on
the roof rack, for a loading height
not exceeding 40 cm (with the ex-
ception of bicycle carriers): 55 kg.
As this value is subject to change,
check the maximum load fi gure
given in the guide provide d with
the roof bars.
If the height exceeds 40 cm,
adapt the speed of the vehicle
to the profi le of the road to avoid
damaging the roof bars and the
fi xings on the vehicle.

TOWING A TRAILER,
A CARAVAN, ETC.
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions. The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.


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 towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed 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 towed load on a long in-
cline depends on the gradient and the
ambient temperature.
In all cases, keep a check on the cool-
ant 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 braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres


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


Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.
