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 hassufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the par ticle emissions filter (PEF).
Wh
y do I sometimes see an aler t message "Electric mode not available: PEF regeneration
in progress"? This is an messa
ge relating to the regeneration of the par ticle emissions filter (PEF). This is acompletely 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.
Wh
y is it not possible for me to put the vehicle
into ZEV mode, even though I had just beenrunning electrically in Auto mode? The mana
gement 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.
Wh
y is the range in ZEV (Zero Emissions
Vehic le) 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 o
f
ZEV (Zero Emissions Vehicle) mode; it does notreturn to ZEV automatically when the conditions allow? It is not intended to give pre
ference 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 m
y 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, ...).
Wh
y 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 (10 0% 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.
Wh
y does the trip computer sometimes displaythe bars for 28 mpg (10 litres) consumption in
town? The current fuel consumption displa
yed 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).
Wh
y 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 takingwhen your foot off the accelerator.
Wh
y are there so may fuel aler t messages whenstarting to use the reser ve?To e n c o u r age 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 % H
ybrid 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 berecharged 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 conver ts kinetic energy intoelectrical 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 b
y the Stop & Start system of
the Diesel engine.
This recover
y allows the use of "free" energy.
The battery charging time is very shor t and iscontinuous.
A discharged battery (following ZEV running or high load, for example) will quickly return to astate of charge sufficient for full operation of the
different hybrid modes.
The charging takes place automaticallywhen driving.
The energy recovery can be faster during deceleration.
The average state of charge is 4 to 5 bars, sopreserving a margin for energy recovery when
deceleration of going downhill (free energy).
To preser ve the ser vice life of thebattery, the level of charge never fallsbelow 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.

Deactivation indicator lamps
If one of the following indicator lamps comes on, this confirms that the corresponding system has been switched off intentionally.This is may be accompanied by an audible signal and a message in the instrument panel screen.

Monitoring
Service indicator
More than 1 800 miles (3 000 km)remain before the next service is due
When the ignition is switched on, no ser vice information appears in the screen. S
ystem which informs the driver when the next ser vice is due, in accordance with themanufacturer's servicing schedule.
The point at which the ser vice is due is calculated from the last indicator zero reset. Itis determined by two parameters:


- the distance travelled,

- the time elapsed since the last ser vice. 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 ser vice operations comes
on. The distance recorder display line indicates the
distance remaining before the next ser vice 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, thescreen indicates:
5 seconds a
fter the ignition is switched on,the spanner goes off; the distance recorder f
resumes its normal operation. The screen thenindicates 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 i
gnition is switched on,
the distance recorder resumes its normal
operation. The spanner remains onto indicate
that a service must be carried out soon.


Illumination of the key is accompaniedby a message in the instrument panel screen.

Service overdue
Every time the ignition is switched on, an
overdue service is immediately signaledby flashing of the spanner and the fixed
illumination of the Service warning lamp.

The distance remaining may be weighted by the time factor, dependingon the driving conditions.
Therefore, the spanner may also comeon if you have exceeded the period since the last service, indicated in the maintenance and warranty guide
.

Following this operation, if you wish to disconnect the battery, lock the vehicle and wait at least five minutes for the zero reset to be taken into account. 5 seconds a
fter the ignition is switched on,
the distance recorder resumes its normal
operation. The spanner remains on.
Service indicator
zero reset
After each ser vice, the ser vice indicator mustbe reset to zero.
The procedure for resetting to zero is as
follows: ) switch off the ignition,)
press and hold the trip distance recorder
zero reset button,) switch on the ignition; the distance recorder
display begins a countdown,
) when the display indicates "=0", release
the button; the spanner disappears.
Retrieving the serviceinformation

You can access the service information at
any time. )Press the trip distance recorder zero reset button.
The ser vice information is displayed for a few seconds, then disappears.
