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.

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.

Access to the underbonnet
Recommendations
Before doing anything under the bonnet, you must switch off the ignition and verify that the RE ADY lamp in the RE ADY lamp in the RE ADYinstrument panel is off - risk of serious injury!
The alternator-starter motor of your HYbrid4 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 ( RE ADY lamp off) before RE ADY lamp off) before RE ADYopening the bonnet.

Electronic gearbox (ETG6)
Six-speed electronic gearbox which offers a choice between two operating modes: - automated mode for automatic control of the gears by the gearbox, - manual mode for sequential gear changing by the driver. In automated mode, it is possible to change gear manually by using the steering mounted control paddles as desired, when overtaking, for example.
R. Reverse  With your foot on the brake, lift the selector and move it for wards. N. Neutral.  With your foot on the brake, select this position to start. A. Automated mode.  Move the selector backwards to select this mode. M. Manual mode with sequential gear changing.  Lift the selector, then move it backwards to select this mode, then use the steering mounted control paddles to change gear.
G e a r s e l e c t o r
+. Change up paddle to the right of the steering wheel.  Press the back of the "+" steering mounted paddle to change up a gear. -. Change down paddle to the left of the steering wheel.  Press the back of the "-" steering mounted paddle to change down a gear.
Steering mounted control paddles
The steering mounted paddles cannot be used to select neutral or to engage or disengage reverse gear.
When immobilising the vehicle, with the HYbrid4 system active, you must place the gear selector in neutral N . Before carrying out any work in the engine compartment, check that the gear selector is in position N , that the
parking brake is applied and that the RE ADY lamp is off before switching off RE ADY lamp is off before switching off RE ADYthe HYbrid4 system.

At very low speed, if reverse gear is requested, this will only be taken into account when the vehicle is immobilised. A warning lamp appears in the instrument panel screen. Only engage reverse gear R when the vehicle is immobilised with the brake pedal pressed.
On sharp acceleration in manual mode, the gearbox will not change up unless the driver acts on the gear lever or the steering mounted paddles. Never select neutral N while the vehicle is moving.
A disappears and the gears engaged M1...M6 appear successively in the instrument panel screen.
The gear change commands are only carried out if the engine speed permits. The internal combustion engine is still running. It is not necessary to release the accelerator during gear changes. When braking or slowing down, the gearbox changes down automatically to permit acceleration in the correct gear.
This occasional gear change mode enables you to overtake, for example, while still remaining in automated mode.  Operate the + or - steering mounted control paddle. The gearbox engages the gear requested if the engine speed permits. A is still displayed in the instrument panel.
Manual mode
After a few moments without any action on the controls, the gearbox resumes automatic control of the gears.
