Hybrid4 mode selector
The selector allows the user to choose between 4 drive modes for the vehicle. Turn the dial to the right or left; the mode selected is confirmed by illumination of the corresponding i n d i c a t o r.
ZEV mode, to force electric running.
SPORT mode, to make use of the maximum per formance of the vehicle.
4WD mode, to force the vehicle into 4x4 mode.
AUTO mode, for normal use and optimised fuel consumption.
On starting the vehicle: with the gear selector in position N , press the brake pedal and press the START/STOP button to activate the hybrid system. This lamp comes on when the vehicle is ready to move off ("Auto" mode is on by default) and so the driver can press the accelerator. This lamp comes on more or less instantly but may take a few seconds in some cases (in particular, the time needed for pre-heating the Diesel engine in cold weather or, for example, in energy economy mode, ...).
Ready lamp
With the vehicle stationary, press the START/STOP button and check that the Ready lamp is off when leaving the vehicle, other wise the hybrid system will still be active.
For more information, refer to the section on "Underbonnet precautions / warnings".

Sport mode
(Diesel and
electric)
4WD mode **
(Diesel and
electric)
This mode allows more dynamic driving by providing additional performance . Vehicle acceleration and pick-up are maximised by using the capacity of the electric motor, supplementing the power of the Diesel engine. This mode manages the progressiveness of the accelerator, the electronic gearbox and the use of the electric motor. In Sport mode: - The electric motor can be used up to 70 mph (120 km/h).
This mode provides additional traction *** at low speed by driving all 4 wheels of the vehicle continuously: the Diesel engine (front wheel drive) and the electric motor (rear wheel drive) operate simultaneously and permanently. Their coupling is managed electronically to optimise traction on slippery sur faces. In 4WD mode: - Power for the electric motor is provided, if needed, by the alternator-starter motor of the front engine. The Diesel engine operates continuously. - The additional traction from the electric motor is available up to 75 mph (120 km/h).
In ZEV mode: - Range and acceleration capacity are limited. The maximum speed possible is around 36 mph (60 km/h). - Under high load or a priority requirement causing the start of the Diesel engine, the system changes automatically to AUTO mode.
If the conditions do not allow this mode, a message that the "electric mode is not currently available" appears in the screen. The ZEV warning lamp flashes for a few seconds then goes off and the selector comes on in AUTO.
This mode should be used on snow covered roads or difficult ground (mud, sand, ...). In this mode, in severe conditions and if the circumstances allow, it is recommended that you accelerate strongly to ensure that you move off and avoid any risk of getting stuck. The addition of 4WD traction is available whatever: - the state of charge of the traction battery, - the altitude.
For more information on "Automatic restarting of the Diesel engine or ZEV mode not available", refer to the corresponding section.
** 4WD: 4 Wheel Drive. *** This mode will be even more effective if
suitable tyres are fitted (winter tyres in particular).

The high voltage battery must not in any circumstances be charged from an external source and must only be handled by a workshop technician. There is the risk of serious burns, as well as electric arcs that could cause serious injury or even death. A used Ni-MH (Nickel Metal Hydride) type high voltage battery must be removed in an appropriate manner by a repair workshop, so that its recycling presents no risk to the environment.
High voltage
The voltage used for the operation of the electric motor is in the range 150 to 270 Volts. Be sure to take account of the warning labels fitted to the vehicle. Take great care regarding the high voltage and high temperatures of components carrying the current.
Emergency cut-off
In the event of an accident, a cut-off system blocks the high voltage current and cuts off the fuel pump; your vehicle can no longer be started.
To restart the hybrid system, contact a CITROËN dealer.
High voltage cables are routed under the vehicle (sills); take care not to damage them when the vehicle is used for off-road activity (such as covering rough ground).
Before doing any work on the vehicle, switch off the ignition ( Ready lamp off).
Battery precautions
High voltage cables
Take care to position lifting equipment ( jack, hoist, ...) at the locations provided to avoid damaging the cables.
Never touch, dismantle, remove or replace the high voltage parts, orange cables or connectors, even in the event of an accident.

Underbonnet precautions / warnings
The alternator-starter motor of your hybrid vehicle is also supplied at high voltage. If the vehicle ignition has not been switched off, there is a risk of the engine restarting at any time.
Always ensure that the ignition is switched off ( Ready lamp off) before opening the bonnet.
Before doing anything under the bonnet, to avoid the risk of serious injury switch off the ignition and verify that the Ready lamp in the dashboard is off. Also ensure that the ignition is switched off when refuelling to avoid the engine restarting.
