Hybrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
QuestionAnswer
Why is it not always possible for me to put the vehicle into ZEV (Zero Emissions Vehicle) mode even though the battery is well charged?
This situation is temporary. Certain conditions will occasionally prevent the change to ZEV mode, even if the battery has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the particle emissions filter (PEF).
Why do I sometimes see an alert message "Electric mode not available: PEF regeneration in progress"?
This is an message relating to the regeneration of the particle emissions filter (PEF). This is a completely normal process that takes place every 240 or 300 miles (400 or 500 km) (or more frequently in prolonged urban use), as on a conventional HDi vehicle. This process is not generally noticed by the driver. On the other hand, in the case of a hybrid, this phenomenon may be noticeable (in urban use) as temporarily the HDi engine will not stop and this message will be displayed at intervals while regeneration is in progress.
Why is it not possible for me to put the vehicle into ZEV mode, even though I had just been running electrically in Auto mode?
The management of ZEV is different from Auto mode. Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to assure sufficient range. In Auto mode, the system alone manages the conditions for changing temporarily to electric mode, for shorter periods and with a lower state of charge of the battery.
Why is the range in ZEV (Zero Emissions Vehicle) mode lower when climbing? The vehicle needs more energy when climbing than when running on the level. So it is better to stay in Auto mode, which will favour operation of the Diesel engine.
Why is it that the system makes me come out of ZEV (Zero Emissions Vehicle) mode; it does not return to ZEV automatically when the conditions
allow?
It is not intended to give preference to ZEV running at any cost, as it is not always the most economical mode. So the system returns automatically to Auto mode.

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 (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 operation) 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) consumption in
town?
The current fuel consumption displayed may 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 town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid 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 avoid the loss of hybrid functions.

Consumption of your hybrid in the screen
Average consumption over the last 5 minutes.
"60 % Hybrid Use" corresponds to 60 % of the cumulative running time with the addition of the hybrid system and 40 % of the time with the Diesel engine only (with no contribution from the hybrid system).
For more information on the trip computer, refer to the corresponding section.
Resetting the history
With the hybrid system active, when trip 2 displayed, press the control for 2 seconds to reset the history to zero.

200 V high voltage battery
The 200 V high voltage battery cannot be recharged from a mains supply. The battery is Ni-MH (Nickel Metal Hydride) and is located below the boot floor, close to the electric motor.
Charging
The battery is charged when the vehicle decelerates, 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)). The battery is not recharged from a mains supply. The battery may also be charged automatically when required by the alternator-starter motor (Stop & Start) of the Diesel engine.
This recovery allows the use of "free" energy. The battery charging time is very short and is continuous. A discharged battery (following ZEV running or high load, for example) will quickly return to a state of charge sufficient for full operation of the different hybrid modes. The charging takes place automatically when driving . The energy recovery can be faster during deceleration. The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration of going downhill (free energy).
To preserve the service life of the battery, the level of charge never falls below 20 %, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower level.

Service indicator
More than 1 800 miles (3 000 km) remain before the next service is due
When the ignition is switched on, no service information appears in the screen.
System which informs the driver when the next service is due, in accordance with the manufacturer's servicing schedule. The point at which the service is due is calculated from the last indicator zero reset. It is determined by two parameters: - the distance travelled, - the time elapsed since the last service. Between 600 miles (1 000 km) and 1 800 miles (3 000 km) remain before the next service is due
For 5 seconds after the ignition is switched on, the spanner symbolising the service operations comes on. The distance recorder display line indicates the distance remaining before the next service is due. Example: 1 700 miles (2 800 km) remain before the next service is due. For 5 seconds after the ignition is switched on, the screen indicates:
5 seconds after the ignition is switched on, the spanner goes off ; the distance recorder the spanner goes off ; the distance recorder the spanner goes offresumes its normal operation. The screen then indicates the total and trip distances.
Less than 600 miles (1 000 km) remain before the next service is due
Example: 560 miles (900 km) remain before the next service is due. For 5 seconds after the ignition is switched on, the screen indicates:
5 seconds after the ignition is switched on, the distance recorder resumes its normal operation. The spanner remains on to indicate that a service must be carried out soon.
Illumination of the key is accompanied by a message in the instrument panel screen.
