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.
Z E V m o d e
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode allows silent and clean running at moderate speeds.
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: - 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 AUTOmode.
For more information on the special conditions for the operation of ZEVmode, refer to the corresponding section.
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 engine when 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 It is no longer active above 75 mph (120 km/h).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 mode.

S P O R T m o d e
(Diesel and
electric)
This mode allows more dynamic driving by providing additional performance . By using the capacity of the electric motor to supplement the power of the HDi Diesel engine, the vehicle's full power is used for acceleration and pick-up. This mode manages the response of the accelerator, the electronic gearbox and the use of the electric motor.
4 W D m o d e
(4 - wheel
drive)
This "4-wheel drive" mode provides additional traction at low speed by driving all four wheels of the vehicle simultaneously: the HDi Diesel engine (front wheel drive) and the electric motor (rear wheel drive) operate simultaneously and permanently. Their coupling is managed electronically to optimise traction when grip is poor.
This mode should be used on snow covered roads or difficult ground (mud, sand, ...), as well as for crossing a ford, at moderate speed. In this mode, in severe conditions and if the circumstances allow, it is recommended that you accelerate strongly to facilitate moving off and making progress and so reduce the risk of getting stuck.
This mode will be even more effective if the vehicle is fitted with suitable tyres, such as winter tyres.
In 4WD mode: - the HDi Diesel engine operates continuously; if necessary, it supplies energy for the electric motor, - the additional traction from the electric motor is available up to 75 mph (120 km/h).
In SPORT mode: - the electric motor as an addition is available up to 75 mph (120 km/h).
This mode is available whatever: - the state of charge of the high voltage battery, - the altitude.

"ECO OFF" function
This function prevents the HDi Diesel engine being switched off and ensures that a comfortable temperature can be maintained in the passenger compartment. This therefore allows the air conditioning or heating to be kept running. Depending on version, the control is either in the switch panel alongside the steering wheel, or in the " Driving " menu of the touch screen.
The function is deactivated on switching off the ignition.
With the touch screen button
During phases of electric running and when the internal combustion engine is stopped,
the HYbrid4 system manages restarting automatically to maintain the temperature in the passenger compartment * . However, variations in temperature may still be felt in very high ambient temperatures. In this case, activate the ECO OFF function.
With the switch on the dashboard
Pressing this switch again reactivates the system. The indicator lamp in the switch goes off, accompanied by the display of a message. The HYbrid4 system returns to normal operation.
* Except in ZEV mode, which gives preference to electric running over maintaining a comfortable temperature.
Pressing this button again reactivates the system. The indicator lamp in the button goes off, accompanied by the display of a message. The HYbrid4 system returns to normal operation
 Press this switch. Deactivation is confirmed by the illumination of the indicator lamp in the switch and the display of a message. The HDi Diesel engine then restarts immediately and operates continuously.
 Select the "Driving" menu.
 In the page, press this button.
Deactivation is confirmed by the illumination of the indicator lamp in the button and the display of a message. The HDi Diesel engine then restarts immediately and operates continuously.

Driving recommendations
Observe the driving regulations 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.
- 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 PEUGEOT dealer or a qualified workshop.
If you are obliged to drive through water: 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), to allow running in electric mode when driving at low speed. Anticipate the need to slow down and use engine braking ( CHARGE zone), so as to make use of the recovery of "free" energy, while maintaining light pressure on the accelerator pedal.
For information on other eco-driving practices, refer to the corresponding section of the handbook for the vehicle.

Special conditions for the operation of ZEV mode
ZEV mode can be selected when all of the conditions for its operation are met, in particular an adequate state of charge of the battery (50% at least). In the situations described below, the HDi Diesel must be running; accordingly, ZEVmode cannot be selected or is deactivated automatically. The mode selector remains at or returns to the AUTO position to allow starting of the HDi Diesel engine.
Cases of non availability of ZEV mode or automatic return
to AUTO mode
- Manual gear change when in automatic mode using the steering mounted controls
for the electronic gearbox.
- Selection of manual mode by moving the gear selector for the electronic gearbox to position M .
- Sustained and sharp acceleration.
- Use of demisting / defrosting.
- Intensive use of air conditioning.
Action by the driver:

Maintaining the performance of the system:
- During phases of regeneration of the particle filter (FAP), which is automatically triggered approximately every 300 miles (500 kms) for a period of about 10 minutes. During regeneration of the particle filter, the particles a brought up to a high temperature using the HDi Diesel engine; A message is then displayed: " Electric mode not available: FAP regeneration ".
- If the state of charge of the high voltage battery is lower than 4 bars (equal to 50% charged). In AUTO mode, electric operation is possible with a lower state of charge.
- When the speed of the vehicle exceeds 18 mph (30 km/h), if the internal combustion engine has not already started at least once since the HYbrid4 system was started.
- When the fuel level enters the reserve zone (illumination of the low fuel warning lamp). Where this reserve is is being used up quickly, ZEV may not be possible for some time after refuelling.
- If certain conditions or engine temperature requirements needed by the HDi Diesel engine are not met (for example, in wintry conditions).
- Following a prolonged period with the vehicle parked in the sun.
- When the state of charge of the high voltage battery is close to the maximum level (for example: when going down a long hill using the electric motor for braking), recovery of the vehicle's kinetic energy being no longer possible, the HDI Diesel engine restarts automatically just to provide engine braking.
- On a steep rising slope.
- Driving at altitude.

200 V high voltage battery
The Ni-Mh (Nickel-Metal Hydride) technology used for the high voltage battery is suited to the frequent partial charging and discharging cycles related to the operation of a hybrid vehicle. The battery is installed close to the electric motor, below the boot trim, behind the storage well.
Charging
The battery recharges automatically while travelling. The battery is charged when the vehicle decelerates and when going downhill, the electric motor then becomes a generator and converts kinetic energy into electrical energy (except if the speed of the vehicle is above 70 mph (120 km/h)). This recovery allows the use of "free" energy. The battery may also be partially charged up to a level of 4 to 5 bars, using the alternator-starter motor (Stop & Start) of the HDi Diesel engine.
The battery charging time is very short.
To preserve the service life of the battery, the level of charge never falls below 20%, even if no bars are displayed on the gauge after ZEVrunning. Where the battery is close to maximum,
vehicle deceleration with your foot off the accelerator pedal will be at a lower level.
The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration or going downhill (free energy).
The battery is not recharged from a mains power supply.
Once it is discharged, following ZEV running or high load, the battery will reach its optimum
level of charge after around 10 minutes.
