Mise en route / Arrêt du moteur (H79 Ph2 - Dacia)
ENG_NU_1079-3_H79Ph2_Dacia_2
Stopping the engineWith the engine idling, turn the key
back to “Stop” position St.
Special note
Depending on the vehicle, accessories
(e.g. radio) stop working either when
the engine is switched off or when the
driver’s door is opened or when the
doors are locked.LPG versionsThe engine is always started using
petrol:
– activate the starter without accelerat- ing;
– release the key as soon as the engine starts.
The system will automatically deter-
mine the switchover from petrol to LPG.
When operating on LPG, the fuel gauge
may indicate a drop in the petrol level
and the on-board computer will not op-
erate.
Every 3,000 miles driven using LPG,
drivers are recommended to drive for
around 3 to 6 miles in petrol mode.
To enable the system to operate
smoothly and to prevent any wear to
the vehicle’s electric petrol pump, the
petrol tank should always be around
1/4 full.
vehicles with an automatic
gearbox
Before starting, move the lever to posi-
tion N or P.
Refer to the information on the
“Automatic gearbox” in Section 2.
Starting the engineIn very cold conditions (temperatures
below –20°C): so that it is easier to
start the engine, switch on the ignition
for several seconds before starting the
engine.
When starting the engine, if the outdoor
temperature is very low (below -10°C):
hold down the clutch pedal until the
engine starts.
Make sure the engine immobiliser is not
activated. Refer to the information on
the “Engine immobiliser” in Section 1.
Petrol injection
– Turn the key to the start position without depressing the accelera-
tor.
– Release the key as soon as the engine starts.
ÉDiesel injection
Turn the ignition key to ignition “On” po-
sition M, and hold this position until the
preheating warning light goes out.
Turn the key to starter position D with-
out depressing the accelerator
pedal.
Release the key as soon as the engine
starts.
STARTING/STOPPING THE ENGINE
Never leave your vehicle
with the key or remote con-
trol inside and never leave
a child (or a pet) unsuper-
vised, even for a short while.
The reason for this is that the child
may endanger himself or others by
starting the engine, activating equip-
ment such as the window winders
for example, or locking the doors.
Risk of serious injury.
Never switch off the ignition
before the vehicle has stopped
completely . Once the engine has
stopped, the brake servo, power as-
sisted steering and passive safety
equipment such as air bags will no
longer operate.
The steering is locked when the key
is removed.

ENG_NU_1079-3_H79Ph2_Dacia_2
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 oil or fuel additives which are not approved by the manufacturer.
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,
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 reg-
ularly taking your vehicle to your ap-
proved dealer at the intervals speci-
fied in your Maintenance Service
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
continue to try and start the engine, but
contact 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
contact with a hot exhaust system.

Particularités des versions diesel (H79 - Dacia)
ENG_NU_1079-3_H79Ph2_Dacia_2
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
Ä and Ò warning lights
come on, consult an approved dealer
as soon as possible.
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 information
on the “Fuel tank” in Section 1 before
restarting the engine.
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.
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 a hot exhaust system.

Fuel gauge warning light A
Warning lights A (4 green lights and
1 red light) indicate the level in the LPG
tank (1 light = approximately 1/5).
The red warning light indicates the fuel
tank.
The amount of LPG indicated is an in-
dicative value.
The red warning light indicates that
the tank is almost empty and that the
engine is operating using the fuel tank
(approximately 11 to 13 litres).
SPECIAL FEATURES OF LPG VERSIONS (1/3)
LPG vehicles
These vehicles operate using petrol or
LPG.
They have two separate tanks.
What is LPG?
LPG stands for Liquefied Petroleum
Gas.
It can be readily identified by its charac-
teristic smell.
An LPG installation on a ve-
hicle may lead to changes
to the vehicle’s features,
compared to petrol ver-
sions. This may relate to the number
of seats, mass (usable capacity)
and towing capacity.
Contact an authorised dealer.
LPG/petrol fuel mode selection
control C
This enables the driver to switch from
one fuel to another.
Green warning light D
A lit warning light indicates that LPG
mode is selected,
Yellow warning light B
A lit warning light indicates that petrol
mode is selected.
If the yellow warning light is
on while the green warning
light flashes slowly and a
beep is heard, please take
your vehicle to an authorised dealer
for inspection.

mode selection control C once the vehi-
cle is started.
To switch from petrol to LPG
Press control C. The vehicle will switch
to LPG the next time the accelerator

press the control C.
Petrol mode is indicated by the yellow
warning light B.
Automatic switch to petrol
The system automatically switches to
petrol mode if there is no more LPG
remaining in the tank. You will be in-
formed by:
– the green D and yellow B warning
lights coming on;
– a beep sounds.
Pressing control C stops the beep from
sounding and only the yellow warning
light B stays on. Operating fault
In the event of a fault which may affect
the correct operation of the engine, the
system automatically switches from
LPG to petrol mode.
This is confirmed by:
– the appearance of the yellow warn-
ing light B;
– slow flashing of the green warning light D;
– a beep sounds.
If the yellow warning light is
on while the green warning
light flashes slowly and a
beep is heard, please take
your vehicle to an authorised dealer

SPECIAL FEATURES OF LPG VERSIONS (3/3)
If driving under severe
conditions
If driving under severe conditions
(heavily laden vehicle, high outside
temperature, starting on a steep slope,
etc), you are recommended to switch to
petrol mode.
In the event of an accident
The main precautions to be taken are
the same as with petrol vehicles:
– apply the handbrake;
– stop the engine (a safety device that stops LPG from entering the engine
is automatically triggered);
– switch off the ignition;
– observe local regulations.
LPG has a very specific
smell so you will be able to
detect any leaks easily. If
you smell gas in your vehi-
cle or immediately surrounding your
vehicle:
– switch to petrol mode immedi- ately and make sure there are no
flames or sources of fire near the
vehicle;
– go to an authorised dealer.
Do not touch, hit or dis-
mantle any part of the LPG
system components.
