"AUTO" mode
It automatically manages the operation of the
Diesel engine and the electric motor, according
to vehicle parameters, traffic conditions and
driving style so as to optimise the vehicle's
fuel consumption.
th

is mode activates "zero emissions"
electric running when the conditions allow.
In "A

" mode, the electric motor :
-

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,

moving off and changing gear, during

front wheels is inadequate (it automatically
adds 4 wheel drive ),

I

"ZEV" mode
(all electric)
"Zero emissions vehicle" operation is assured
100 % by electric drive.
th
is mode forces silent running at moderate
speeds. If the conditions do not allow this mode,
the message "electric mode is not currently
available" appears in the screen.

"SPORT" mode
(Diesel and
electric)
this mode allows more dynamic driving by
providing additional performance.
Vehicle acceleration and pick-up are
maximised by using the capacity of the electric
motor, supplementing the power of the Diesel
engine.
th

is mode manages the response of the
accelerator, the electronic gearbox and the use
of the electric motor.
In "SPOR
t" m

ode:
-
t
h
e electric motor can be used up to
75 mph (120 km/h).
"4WD" mode*
(Diesel and
electric)
this mode provides additional traction ** at
low speed by driving all 4 wheels of the vehicle
continuously: the Diesel engine (front wheel
drive) and the electric motor (rear wheel drive)
operate simultaneously and permanently.
th

eir coupling is managed electronically to
optimise traction when grip is poor.
In 4WD mode:
-

P
ower for the electric motor is provided, if
necessary, by the alternator-starter motor
of the front engine.
t
h
e Diesel engine
operates continuously.
-
t
h
e additional traction from the electric
motor is available up to 75 mph (120 km/h).th is mode should be used on snow
covered roads or difficult ground
(mud, sand, ...).
In this mode, in severe conditions
and if the circumstances allow, it is
recommended that you accelerate
strongly to facilitate moving off and
reduce the risk of getting stuck.
th

e addition of "4WD" traction is
available whatever:
-

t
he state of charge of the traction
battery,
-

t
he altitude.
Be aware of the ground clearance of
your vehicle: around 184 mm (with the
vehicle in working order: driver only and
the fuel tank full) in ideal conditions.
th

is value will vary with vehicle load,
the nature of the ground sur face and
the surroundings.
If the driver considers that the vehicle
can traverse an obstacle, they assume
entire responsibility for this.
* "4WD": 4 Wheel Drive.
**
t
h
is mode will be even more effective if tyres
more suitable for the conditions are fitted
("winter" tyres in particular). When driving on flooded roads or when
crossing a ford, drive at walking pace.

Reducing consumption - Fuel
QuestionAnswer
How can I optimise my fuel consumption?
gi
ve 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 Z
eV (

Zero e
m
issions
Vehicle) mode? It is not Z
eV m

ode but Auto mode that is the most appropriate for reducing fuel
consumption, as it selects the best "driving energy source".
Z
eV m

ode (100% electric operation) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
th

is 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?
th

e 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).
th

is 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 e

ncourage you to refuel as soon as possible and avoid the loss of hybrid functions.

Your vehicle is fitted with a catalytic converter,
a device which helps to reduce the level of
harmful emissions in the exhaust gases.
You must switch off the
engine


by stopping the
hybrid system (the Ready
lamp must be off) to avoid
any automatic restart of the
engine while refuelling.

Low fuel level
When the low fuel level in the tank is
reached, this warning lamp comes on
in the instrument panel, accompanied
by an audible warning and a message
in the instrument panel screen.
Fuel supply cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.It is still possible to use a fuel can to fill
the tank but this must be done slowly.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device.
Diesel misfuel prevention
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap.
t
h
e system remains
closed and prevents filling.
Do not persist but introduce a Diesel filler
nozzle.
Operation
Travelling abroad
As Diesel fuel pump nozzles may be different
in other countries, the presence of the misfuel
prevention device may make refuelling
impossible.
Before travelling abroad, we recommend that
you check with the P
e

uge
Ot
dealer network,
whether your vehicle is suitable for the fuel
pumps in the country in which you want to
travel.
When it first comes on, around 7 litres of fuel
remain in the tank.
You must refuel as soon as possible to avoid
running out.

In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
I
f the interior temperature remains very high after the vehicle has been parked in the sun
for a considerable time, first ventilate the passenger compartment for a few minutes.
P

lace the air flow control at a sufficient level to provide an adequate renewal of air in
the passenger compartment.
F
t
o o
btain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.
F
u
s
e in preference the intake of exterior air as prolonged use of the air recirculation may
cause misting of the windows and side windows.
F

D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the automatic air conditioning system.
F

O
perate the air conditioning system for 5 to 10 minutes, once or twice a month to keep it
in good working order.
F
e
n
sure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to the "Checks" section).
W

e recommend the use of a combined passenger compartment filter. t
h
anks to its
second special active filter, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F
t
h
e air conditioning uses power from the engine while operating. t
h
is results in an
increase in the vehicle's fuel consumption.
W

hen towing at or near maximum capacity or on steep slopes in high ambient
temperatures, switching off the air conditioning saves engine power and so improves
towing capacity.
C

ondensation created by the air conditioning results in a discharge of water under the
vehicle when stationary, which is per fectly normal.
F
t
o e
nsure correct operation of the air conditioning system, you are also advised to have
it checked regularly.
F

I
f the system does not produce cold air, do not use it and contact a P
e
uge
Ot
dealer or
a qualified workshop.
Recommendations for ventilation and air conditioning
the air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.
