Hybrid4 system

508HY-comp_en_Chap00b_hybrid_ed01-2016

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.

ZEV mode

(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

AUTO

mode.

For more information on the special
conditions for the operation of

ZEV

mode, 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 It is no longer active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.

SPORT mode

(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.

4WD mode

(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.

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

4WD

position,

- 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

Eco-driving

Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel
consumption and CO

2

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,

ZEV

mode 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:

508HY-comp_en_Chap00b_hybrid_ed01-2016

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

ZEV

running.
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.

Safety warnings related to high voltage

Before doing any work on
the vehicle, switch off the
ignition (

READY lamp off).

READY

READY

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).

Operations on the

battery

The high voltage battery must not in
any circumstances be charged from an
external power supply and must only
be handled by a qualified technician
at a PEUGEOT dealer or a qualified
workshop.
Incorrect handling may lead to serious
burns, as well as electric arcs that could
cause serious injury or even death.

Take care to position lifting equipment
(jack, hoist, ...) at the locations provided to
avoid damaging the cables.

The voltage used for the operation of the
electric motor is in the range 150 to
270 Volts.
Do not handle the components of the high
voltage system (identified by the orange
colour): risk of electrocution and burns!

Emergency cut-off

In the event of an accident, a safety
system automatically cuts-off the high
voltage system and the fuel supply.
The HYbrid4 system can no longer be
started.
You must then contact a PEUGEOT
dealer or a qualified workshop.

Never touch, dismantle, remove or replace
the high voltage parts, orange cables
or connectors, even in the event of an
accident.

Be sure to take account of the warning
labels present on the vehicle.
Battery electrolyte is very corrosive: risk
of burns.
No sparks or naked flames.
Do not burn or heat.
Keep out of reach of children.
Do not spray or pour fluids: risk of damage
to the battery.

To avoid any risk to the environment,
the high voltage battery must be
recycled in an appropriate manner.
Contact a PEUGEOT dealer or a
qualified workshop.

508HY-comp_en_Chap00b_hybrid_ed01-2016

Ventilation of the high voltage battery

The high voltage battery has an air cooling
system.
This comprises an air intake (located on the
rear shelf) and a fan (located behind the left
hand boot trim).

This ventilation system does not operate at
the same speed at all times: it is continuously
adjusted to suit the cooling requirements of the
battery.
The noise of its operation can be heard,
particularly at the rear, after the HYbrid4
system is switched off (post-ventilation).

Safety recommendations

Do not obstruct the air intake with
objects such as clothes or bags, in
order to avoid any risk of the battery
overheating, which could cause a loss
of performance of the HYbrid4 system,
even damage to the battery.
Do not spill fluids, as this may damage
the battery and cause a short-circuit.
