Starting the Hybrid4
system
Activation of the Hybrid4 system
On activation of the Hybrid4 system, the instrument panel lights up, the power indicator needle is placed at position " 0 ". The steering column automatically unlocks (perceptible noise and movement of the steering column). Depending on certain parameters, such as the state of charge of the high voltage battery or the ambient temperature, the Hybrid4 system itself determines whether it is necessary to start the HDi Diesel engine. The mode selector is at the AUTO p o s i t i o n .
In wintry conditions with the engine cold, the Diesel pre-heating warning lamp can stay on for a few seconds; wait until it goes off before releasing the brake pedal.
Starting - switching off the Hybrid4 system
Never leave children alone inside the vehicle when the Hybrid4 system is a c t i v e .
 Place the gear selector at position N .  Insert the electronic key in the reader. or  With Keyless Entry and Starting, simply having the electronic key inside the vehicle is sufficient.
 Press the brake pedal firmly.  Make a single short press (about one second) on the " START/STOP " button.  Maintain pressure on the brake pedal until the RE ADY lamp comes on, signalling RE ADY lamp comes on, signalling RE ADYactivation of the Hybrid4 system, confirmed by an audible signal.
If the Hybrid4 system does not start up:  If N is flashing in the instrument panel, move the gear selector to position A then to position N .  If the " Foot on the brake " is displayed, press the brake pedal

A few driving recommendations
Observe the driving regulations at all times and remain vigilant whatever the traffic conditions. Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at any time to any eventuality. On a long journey, a break every two hours is strongly recommended. In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from other vehicles.
Driving on flooded
roads
We strongly advise against driving on flooded roads, as this could cause serious damage to the internal combustion engine or electric motor, the electronic gearbox, or the electrical systems of your vehicle.
If you are obliged to drive through water:
- check that the depth of water does not exceed 15 cm, taking account of waves that might be generated by other users, - place the mode selector in the 4WDposition, - drive as slowly as possible without stalling. In all cases, do not exceed 6 mph (10 km/h), - do not stop and do not switch off the
engine. On leaving the flooded road, as soon as circumstances allow, make several light brake applications to dry the brake discs and pads. If in doubt on the state of your vehicle, contact a CITROËN dealer or a qualified workshop.
Important!
Never drive with the parking brake applied - Risk of overheating and damage to the braking system! Do not park or run the engine when stationary in areas where inflammable
substances and materials (dry grass, dead leaves...) might come into contact with the hot exhaust system or certain components of the Hybrid4 system which can reach very high temperatures - Risk of fire!
Never leave a vehicle unsupervised with the engine running. If you have to leave your vehicle with the engine running, apply the parking brake and put the electronic gearbox into position N .

Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Adapted to your Hybrid4 vehicle
Use gear selector position A , as this optimises gear changes to suit the circumstances, and the AUTO mode of the Hybrid4 mode selector. When moving off, accelerate normally up to the desired speed ( POWER zone between 20 and 40 %). At steady speeds, drive gently with small movements of the accelerator pedal ( ECO or CHARGE zone), run in electric mode as often as possible when driving at low speed. Anticipate the need to slow down and use engine braking ( CHARGE zone), so as to make use of free energy recovery while keeping light pressure on the accelerator pedal.
For information on other eco-driving practices, refer to the corresponding section of the handbook for the vehicle.

Weights and towed loads (in kg)
* The kerb weight is equal to the unladen weight + driver (75 kg). ** The weight of the braked trailer can be increased, within the GTW limit, if the GV W of the towing vehicle is reduced by an equal amount; warning, towing using a lightly loaded towing vehicle may have an adverse effect on its road holding. To make use of the 300 kg load transfer, the driver must be alone in the vehicle with no luggage in the vehicle.

The GTW and towed load values indicated are valid up to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for each additional 1 000 metres of altitude. The maximum authorised speed is reduced when towing (comply with the legislation in force in your country). High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.

Reducing consumption / Fuel
QuestionAnswer
How can I optimise my fuel consumption? Give preference to AUTO mode as it selects in the best way the "driving energy source" to use in order to reduce fuel consumption. You should also adapt your driving style to the characteristics of hybrid vehicles to get the best out of it, for example by taking your foot off the accelerator pedal rather than braking and by anticipating decelerations which allows the recovery of "free" energy for charging the battery (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why do I not manage to reduce my fuel consumption even though I often drive in ZEV (Zero Emissions Vehicle) mode?
It is not ZEV mode but AUTO mode that is the most appropriate for reducing fuel consumption, as it selects the best "driving energy source". ZEV mode (100% electric running) can reduce fuel consumption in some cases. However, recharging the traction battery has an energy cost. This is why we recommend using AUTO mode more often.
Why does the trip computer sometimes display the bars for 28 mpg (10 litres/100 km) in town? In traffic jams, the fuel consumption graph displayed may temporarily appear high when the distance covered is very low, but this generally has very little impact and the true average fuel consumption will remain low. In urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption (by around 35%) compared to a conventional vehicle.
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in AUTO mode). This allows some capacity to be left free for the recovery for energy when going downhill or taking when your foot off the accelerator.
Why are there so may fuel alert messages when starting to use the reserve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all electric running.
