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 per formance. 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.

ZEV mode
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode allows silent and clean running at moderate speeds.
It can be activated when the conditions allow, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).
In AUTO mode, the electric motor : - can power the vehicle on its own in "zero emissions" electric running, depending on the state of charge of the battery, if the conditions specific to the vehicle are met and if acceleration is moderate, - supplements the HDi Diesel enginewhen moving off and changing gear, during acceleration or when traction from the front wheels is inadequate, temporarily providing 4-wheel drive. The electric motor can operate only at speeds below 52 mph (85 km/h). It is no longer active above 75 mph (120 km/h).
Refer to the special conditions for operation of ZEV m o d e .
For more information on the special conditions for the operation of ZEV mode, refer to the corresponding section.
If the conditions do not allow ZEV mode to be selected or maintained, the message " Electric mode is not currently available " appears in the screen. The ZEV indicator lamp flashes for a few seconds then goes off and the indicator lamp in the AUTO position comes on. In ZEV mode: ZEV mode: ZEV - range and acceleration capacity are limited; the maximum speed is around 36 mph (60 km/h), - under high load or a priority requirement causing the start of the HDi Diesel engine, the system changes automatically to AUTO m o d e .

Air conditioning / Heating
QuestionAnswer
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 always 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
QuestionAnswer
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 hybrid components that are also cooled by the engine's cooling system.
Why does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the energy recovery by the electric motor. This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of "free" energy.
