When towing
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
i

t.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
0

00
m
etres, the maximum towed load must
be reduced by 10
% f

or every 1
0
00 metres of
altitude.
Side wind
F Take into account the increased sensitivity
t o 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
To l

ower 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
If t

he 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, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing
v ehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling
o n the trailer and the hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
For more information on weights (and the
towed loads which apply to your vehicle) refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

Air conditioning / Heating



Question



Answer


It seems to me that the vehicle runs less on electric
when the heating or air conditioning is operating, is that
right? The demand for heating or air conditioning may require the starting of the HDi Diesel
engine until the desired level of comfort is attained.
Normal operation of the Hybrid4 system is simply put back. The period can be longer
under very low or very high ambient temperatures.
It seems to me that when it is very hot and the air
conditioning is working, the vehicle runs on electric for
shorter periods. Is that right? When it is hot, the periods when the HDi Diesel engine is put on standby and the vehicle
runs on electric are necessarily restricted in order to limit the difference between the
temperature in the vehicle and the level of comfort selected.
In very hot weather, it is possible to press the " ECO OFF
" button (which brings the vehicle
out of ZEV
mode and prevents electric running or the stopping of the engine) to give
preference to temperature control (keeps the air conditioning running).

Miscellaneous



Question



Answer


Is towing possible with my Hybrid4 vehicle? For information on the towing ability of your Hybrid4 vehicle, refer to " Weights and towed
loads" in the "Technical data" section.
This allows a jet ski or two-wheeler on a trailer to be towed, for example.
This limit is related to maintaining adequate cooling capacity for the HDi Diesel engine as
well as the components of the Hybrid4 system that are also cooled by the engine's cooling
system.
Why does engine braking seem so strong? If the high voltage battery is not fully charged, the engine braking results mainly from the
energy recovery by the electric motor. The power of this engine braking is higher than that
of an internal combustion engine.
