Mode selector
The selector allows the driver to select one of the four operating modes offered by the Hybrid4 system.  Turn the dial to the right or left; the mode selected is confirmed by illumination of the corresponding indicator lamp.
ZEV mode: for 100% electric running.
SPORT mode: to make use of the maximum per formance of the vehicle.
4WD mode: to force 4x4 drive.
AUTO mode: for everyday use and optimised fuel consumption.
By default, the selector is in the AUTO position when starting the Hybrid4 system, whatever position it was in when the ignition was switched off.
AUTO mode
This mode is designed to optimise the vehicle's fuel consumption by managing the alternate or simultaneous operation of the two motors according to the conditions and driving style. When conditions allow, an adequate battery state of charge and moderate acceleration, the alternator-starter motor stops the HDi Diesel engine to provide 100% electric running.

ECO OFF function
This function prevents the HDi Diesel engine being switched off and so ensures that a comfortable temperature can be maintained in the passenger compartment (air conditioning running continuously). On pressing the ECO OFF switch, the HDi Diesel engine restarts immediately. To return to normal operation, press this switch again. After switching off the ignition, the vehicle will return to normal operation (lamp in the switch off).
* E x c e p t i n ZEV mode, which gives preference to electric running over maintaining a comfortable temperature.
During electric running and when the engine is stopped, the hybrid system manages restarting automatically to maintain the temperature in the passenger compartment * . However, variations in temperature may still be felt in very hot climates. To avoid any discomfort in these conditions you can operate the ECO OFF s w i t c h .

The high voltage battery must not in any circumstances be charged from an external source and must only be handled by a qualified technician at a CITROËN dealer or a qualified workshop. 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 c u r r e n t .
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 ( RE ADY l a m p o f f ) . RE ADY l a m p o f f ) . RE ADY
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.

Recovery of the vehicle on a fl at-bed
Never recover the vehicle by towing it with two or four wheels on the ground, as there is a risk of damage to the transmission. However, if necessary because access to the vehicle is difficult, the vehicle can be moved a few dozen metres, at a speed of less than 6 mph (10 km/h).
Use the towing eye only to pull the vehicle out or to lash it for recovery on a flat-bed lorry or

Before doing any work, with the ignition on, press the brake pedal and place the gear selector at position N , then switch off the Hybrid4 system ( RE ADY lamp off). RE ADY lamp off). RE ADY Always call on professionals for recovery of the vehicle on a flat-bed lorry or trailer.
Snow chains
Recommendations
