2.14
SPECIAL FEATURES OF PETROL VERSIONS
The following operating conditions:
– 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 system, running out of fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power,
as they may cause the catalytic con-
verter to overheat and thus reduce its
efficiency, or damage it irreparably
and cause heat damage to the vehi-
cle. 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
starting fault.
If the fault cannot be identified, do not
keep trying to start the engine, but con-
tact an approved Dealer.
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 con-
tact with the hot exhaust system.

2.15
SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with an injec-
tion pump which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollution
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.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: See “Fuel
tank” in section 1 before restarting the
engine.
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.

2.17
ELECTRONIC PARKING BRAKE (1/3)
Note:
To indicate that the electronic parking
brake is released, a beep sounds and
the message “Apply parking brake” ap-
pears on the instrument panel:
– with the engine running: when the driver’s door is opened;
– with the engine switched off (eg. when the engine stalls): when a front
door is opened.
In this case, pull and release switch 2 to
apply the assisted parking brake.
Assisted release of the parking
brake
The brake will be released as soon as
the vehicle starts and accelerates.
Assisted operation
The electronic parking brake immobi-
lises the vehicle when the engine is
switched off by pressing the engine
start/stop button 1 or by turning the
ignition key (key in the “ ON" 2 po-
sition).
In all other circumstances, for example
stalling of the engine or placing of
the engine on standby by the Stop
and Start function (refer to the informa-
tion on the "Stop and Start" function in
Section 2), the electronic parking brake
is not applied automatically. Manual
mode must be used. For certain country-specific model ver-
sions, the assisted brake application
function is not activated. Refer to the
information on “Manual operation”.
To confirm that the electronic parking
brake is applied, the message “Parking
brake on” and warning light
}
on the instrument panel and warning
light 3 on the switch 2 light up.
After the engine is switched off, indi-
cator light 3 goes out several minutes
after the electronic parking brake has
been applied and indicator light
}
goes out when the vehicle is locked.
Before leaving the vehi-
cle, check that the assisted
parking brake is fully ap-
plied. Warning light 3 on
switch 2 and warning light
}
on the instrument panel light up to
show that the parking brake is ap-
plied but go out when the doors are
locked.

Operating faults
– If there is a fault, the © warning
light illuminates on the instrument
panel accompanied by the “Check
parking brake” message and, in
some cases, the
} warning
light.
Please contact an authorised dealer
as soon as possible.
– If there is an assisted parking brake fault, the warning light
® comes
on, along with the message “Braking
system fault”, a beep and, in some
cases, the warning light
}.
This means that you must stop as
soon as traffic conditions allow.
Versions with an automatic
gearbox
For safety reasons, automatic release
is deactivated when the driver’s door
is open or not shut properly and the
engine is running (in order to prevent
the vehicle from moving without the
driver). The “Release parking brake
manually” message appears on the
instrument panel when the driver de-
presses the accelerator.
ELECTRONIC PARKING BRAKE (3/3)
It is therefore essential to
immobilise the vehicle by
engaging first gear (manual
gearbox) or position P (au-
tomatic gearbox). If the slope re-
quires it, chock the vehicle.
Never leave your vehicle
without moving the selec-
tor lever to position P and
switching off the engine.
This is because when the vehicle is
stationary with the engine running
and a gear engaged, the vehicle
may begin to move.
There is a risk of accidents.If no lights or sounds are ap-
parent, this indicates a fault
in the instrument panel. This
indicates that it is essential
to stop immediately (as soon as traf-
fic conditions allow). Ensure that the
vehicle is correctly immobilised and
contact an approved Dealer.
If the message “Electric fail-
ure DANGER” or “Check
battery” appears, manually
activate the electronic park-
ing brake by pulling switch 2 (or po-
sition the gear lever in P for auto-
matic gearboxes) before stopping
the engine.
Risk of loss of immobilisation of the
vehicle.
Contact an authorised dealer.
