2.12
SPECIAL FEATURES OF PETROL VERSIONS
Do not park the vehicle or
run the engine in locations
where combustible sub-
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
The following operating conditions
should be avoided:
– driving for long periods when the low fuel level warning light is lit;
– using leaded petrol;
– using fuel or lubrication additives which are not approved.
Or operating faults such as:
– faulty ignition, running out of fuel or disconnected spark plugs resulting
in the engine misfiring or cutting out
when driving;
– loss of power,
may cause the catalytic converter to
overheat, reducing its efficiency which
may irreparably damage it and cause
heat damage to the vehicle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved dealer.
These faults may be avoided by regu-
larly taking your vehicle to an approved
Dealer at the intervals specified in the
Maintenance Document.
Starting problems
To avoid damaging the catalytic con-
verter,
do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
cause of the fault.

2.13
SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with injection
equipment which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check anti- pollution
system” is displayed along with warn-
ing lights
Ä and ©, consult an
authorised dealer immediately.
When driving, depending on the fuel
grade used, it is possible that white
smoke may be emitted.
This is due to the exhaust particle filter
being cleaned automatically, and does
not affect the way the vehicle runs.
Do not park the vehicle or
run the engine in locations
where combustible sub-
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully charged,
– always keep the diesel tank rela- tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

2.16
The “Hybrid Assist” system uses an
electric motor to improve performance
of the combustion engine (acceleration,
starting on a slope etc.). The vehicle
has more acceleration torque available
while consuming less fuel.
BatteriesYour electric vehicle has two types of
battery:
– a 48 V traction battery;
– secondary 12 V battery.
“48 volt” traction battery
Located under the rear floor, this bat-
tery stores the energy recovered during
phases of deceleration. This energy is
used by the hybrid system to provide
additional torque to the combustion
engine.
“HYBRID ASSIST" SYSTEM: introduction (3/5)
Secondary 12V battery
The 12 V battery supplies the energy
required to operate vehicle equipment
(lights, windscreen wipers, ABS etc).
Please see the information under
“12 volt battery” in Section 4.
“48 volt” electrical circuit
The 48 V electrical circuit is denoted
by orange cables and parts bearing the
symbol
ṑ.
All interventions or modi-
fications to the vehicle’s
48 volt electrical system
(components, cables, con-
nectors, traction battery) are strictly
prohibited due to the risks this may
present to your safety. Call an ap-
proved Dealer.
Risk of electric shock.
A
The A symbol denotes the electrical
elements of your vehicle which may
present health risks.
The traction battery does
not require any mainte-
nance. You should not open
it or add any fluid.
Risk of electric shock.

2.18
Operating faults
– If the  warning light on the in-
strument panel comes on, this indi-
cates that an operating fault has oc-
curred in the system. The operation
of the vehicle is still maintained ;
–
Ú and ® lit up on the in-
strument panel accompanied by the
message “Electric failure DANGER”
indicates a system fault.
For approximately 30 seconds,
the
Ú warning light lights up
on the instrument panel accompa-
nied by the message “Electric failure
DANGER”.
Over the following 30 seconds, the vehicle progressively loses power
from its combustion engine.
Approximately two minutes after the first time the warning appears, the
vehicle speed is limited to 4.34 mph
(7 km/h) approximately.
In all cases, please consult an
Authorised Dealer.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow. Switch off the engine and do
not restart it. Contact an approved
Dealer.
