ENGINE IMMOBILISER
This prevents the vehicle being
driven by anyone not in possession
of the vehicle’s coded ignition key.
Any work or
modification to the
engine immobiliser
(computer, wiring, etc.)
may be dangerous. It must be
carried out by trained Renault
network personnel.
Operating principle
The vehicle is automatically
protected a few seconds after taking
the key out of the ignition.
When the ignition is switched on,
tell-tale light1illuminates steadily
for a few seconds and then
extinguishes.
The vehicle has recognised the code
and the engine can be started.
If the vehicle does not recognise the
code of the ignition key, tell-tale
light1flashes continuously and the
engine cannot be started.
Tell-tale light relating to the
engine immobiliser
• Vehicle protection tell-tale light
A few seconds after the ignition
has been switched off, tell-tale
light1will flash continuously.
The vehicle will not be protected
until the key has been taken out of
the ignition.
•Tell-tale light to indicate the
engine immobiliser is operating
When the ignition has been
switched on, tell-tale light1
illuminates steadily for a few
seconds and then extinguishes.
You can then start the engine.

METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS(continued)
Airbagfordriverandfront
passenger
(continued)
Each air bag system consists of:
- An air bag and gas generator fitted
on the steering wheel for the
driver and in the dashboard for the
front passenger.
- A computer for both systems
which includes the impact
detector and a monitor controlling
the electrical trigger system for the
gas generator.
- One single tell-tale light1on the
instrument panel.Operation
The system is only operational after
the ignition has been turned on
(ignition key in positionM“ignition
on”).
If a severefrontalimpact occurs, the
air bag(s) inflate(s) in approximately
30 millisecond(s), cushioning the
impact of the driver’s head against
the steering wheel and the front
passenger’s head against the
dashboard. The air bag then deflates
immediately so that the passengers
are not impeded in any way when
they get out of the vehicle.
Theairbagsystemusesthe
principles of pyrotechnics. This
explains why, when the air bag
inflates, it will generate heat,
produce smoke (this does not mean
that a fire is about to start) and make
a noise upon detonation. In a
situation where an air bag is
required, it must inflate
immediately and this may cause
some minor, superficial grazing to
the skin.Operating fault
Tell-tale light1illuminates on the
instrument panel when the ignition
is turned on and then extinguishes
after a few seconds. If it does not
illuminate when the ignition is
turned on or if it flashes, there is a
fault in the system.
Consult your Renault Dealer as soon
as possible. Your protection will be
reduced until this problem is
rectified.

trip mileage counters
For example, to reset the trip
mileage, the display must be set to
“trip mileage”.
Automatic resetting
The trip mileage recorders will b
reset automatically when the
maximum capacity of any of the
memories is exceeded.3Display selection key
Keep pressing key3briefly to
show the following information
in sequence:
a) total mileage recorder,
b) trip mileage recorder,
c) fuel consumed,
d) average consumption,
e) current consumption,
f) estimated range,
g) distance covered,
h) average speed.
Display flashing
Consult a Renault Dealer if the
display flashes.
Interpreting certain values
displayed after resetting
The values showing average fuel
consumption, range and average
speed will become more stable and
reliable the further you travel since
thelasttimetheresetkeywas
pressed.For the first few miles after pressing
the reset button you will notice:
• that the range increases as you
travel. This is normal. Average
fuel consumption may decrease
when:
- The car stops accelerating.
- The engine reaches its operating
temperature (engine cold when
start button pressed).
- When you drive from a built up
area on to the open road.
Therefore, if the average fuel
consumption decreases, the range
will increase.
•Youmayalsonoticethatthe
average fuel consumption
increases when the vehicle is
stationary and the engine idling.
This is normal since the module
takes account of fuel used during
idling.

FUEL TANK(continued)
Fuel grade
Use the fuel which corresponds to
the grade defined by the standards
of the country you are in.
Refer to “Engine specifications”.
Any operation on or
modification to the fuel
supply system (computers,
wiring, fuel circuit,
injector, protective covers...) is
strictly forbidden due to the
safety risks it may entail (except
for qualified staff from the
Renault network).
Filling with fuel
Only useunleadedfuel.
Using leaded petrol will damage the
anti-pollution system and may lead
to a loss of warranty.
To ensure that the fuel tank is not
filled with leaded petrol, the fuel
tank filler neck contains a restrictor
fitted with a valve whichonly
allows the nozzle for unleaded
petrol to be used(at the petrol
pump).
- Insert the nozzleas far as it will go
so as to open the valve.
- Start to fill the tank with fuel and
keep the nozzle in this position
throughout the entire filling
operation.
No more than two filling
operations may be made after the
fuel feed has switched off
automatically for the first time
because there must be sufficient
space in the fuel tank to allow for
expansion.
Persistent fuel odour
Your vehicle has a pressurised fuel
supply circuit. If a persistent fuel
odour occurs you should:
•stop the vehicle if traffic
conditions allow and switch off
the ignition;
• switch on the hazard warning
lights and ask your passengers to
leave the vehicle and stay clear of
the traffic;
• do not operate on or restart the
vehicle before it has been
inspected by qualified staff from
the Renault network.

STARTING/STOPPING THE ENGINE
Starting the engine
In the case of an automatic
transmission
Refer to the information on
automatic transmissions in section 2.
Special feature on vehicles equipped
with an engine immobiliser system
In very cold conditions (temperatures
below –20°C): so that it is easier to
start the engine, switch on the
ignition for several secondsbefore
starting the engine.
Make sure the engine immobiliser is
not activated (see section 1 on the
engine immobiliser).
Petrol injection
Turn the key to the “start” position
without accelerating.
Release the key as soon as the
engine starts.If there is a child (or
animal) in the car, never
leave it unattended with
the key in the ignition.
With the key in the ignition it
would be possible to operate
electrical equipment such as the
windows and there is a risk that the
child may be seriously injured (by
trapping his or her neck, arm,
hand, etc.).
Never switch off the ignition before
the vehicle has stopped completely.
Once the engine has stopped, the
power steering, brake servo and
passive safety devices such as air
bags and pretensioners will no
longer operate. When the key has
been removed, the steering will
lock.
Stopping the engine
With the engine at idling, turn the key
back to the “stop” position.

SPECIAL POINTS RELATING TO PETROL VERSIONS
The following operating conditions
may cause the catalytic converter to
overheat and thus reduce its
efficiencyor even destroy it and
cause heat damage to the vehicle:
• Driving for a long time with the
low fuel level warning light
illuminated;
• Faulty ignition, running out of
fuel or spark plug disconnected
occurring as engine misfiring and
snatches when driving;
• Using leaded petrol;
• Using lubrication additives or
fuel which is not approved by
Renault;
• Loss of power;
• The fitting of non-recognised
security systems which have been
integrated into the fuel injection
system for immobilisation
purposes;
• Bump starting the vehicle, as
unburntpetrolinthesystemmay
affect the catalyst if the car does
not start quickly. However, jump
starting with jump leads across
the battery is permissible.If you note any of the above
incidents, have the necessary
repairs carried out as soon as
possible by your Renault Dealer.
Theseincidentsmaybeavoidedby
taking your vehicle regularly to
your Renault Dealer at the intervals
specified in your servicing booklet.
Starting problems
To avoid damaging the catalytic
converter,do not keep trying to
startthe engine (using the ignition
key, or by pushing or pulling the
vehicle)without having identified
and corrected the starting fault.
If the fault cannot be identified, do
not persist in attempting to start the
engine. Call a Renault Dealer.
Do not park the vehicle or
run the engine in locations
where combustible substancesormaterialssuchasgrassor
leaves can come into contact with a
hot exhaust system.
