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.

notches to hold the car. Your vehicle
is fitted with self-adjusting rear
brake shoes and the handbrake
should only be adjusted during a
brake overhaul.
When the vehicle is
stationary, make sure
that the handbrake is
properly applied so that
the vehicle does not move
unintentionally.

ADVICE ON ANTI-POLLUTION AND HOW TO ECONOMISE ON FUEL, DRIVING
RENAULT is actively participating
in the reduction of pollutant
exhaust gas emissions and in saving
energy.
By virtue of its design, moderate
fuel consumption and initial
settings your Renault conforms to
current anti-pollution standards.
Technical design, however, cannot
achieve all. The fuel consumption
of your car and the level of pollutant
exhaust gas emissions are very
much within your control. Make
sure that your vehicle is maintained
correctly, use it carefully and watch
your driving style.Maintenance
It should be noted that failure to
respect anti-pollution standards
may lead to legal action being taken
against the vehicle owner. In
addition, the replacement of parts of
the engine, fuel supply system and
exhaust by parts other than those
originally recommended by the
manufacturer may alter your
vehicle such that it no longer
complies with anti-pollution
standards.
Have your vehicle checked and
adjusted by your Renault Dealer in
accordance with the instructions in
the vehicle’s servicing booklet.
Your Renault Dealer has all the
equipment necessary for ensuring
your vehicle is maintained in its
original standard.
Always remember that the emission
of pollutant fumes is directly linked
to fuel consumption.
Engine adjustments
• Ignition:This does not require
adjustment.
•Spark plugs:Optimum
conditions of use, performance
and output demand that the
specifications laid down by our
design office be rigorously
adhered to.
If the spark plugs have to be
changed, use the make, type and
gap specified for your vehicle’s
engine. Consult your Renault
Dealer for this information.
•Idling speed:This does not
require adjustment.
•Air filter:A choked element
hinders output and must be
changed.
•Injection pump setting:It must be
set to the recommended values.

ADVICE ON ANTI-POLLUTION AND HOW TO ECONOMISE ON FUEL(continued)
Monitoring exhaust gas
The exhaust gas monitoring system
will detect any malfunctioning of
the vehicle’s exhaust gas
depollution system.
If this system malfunctions, toxic
substances may be released into the
atmosphere or mechanical damage
may occur.
This warning light on the
instrument panel will
indicate if there are any
problems with the system.
It illuminates when the ignition is
switched on and extinguishes
within 3 seconds.
- If it illuminates continuously,
consult your Renault Dealer as
soon as possible.
- If it flashes, reduce the engine
speed until the light stops
flashing. Consult your Renault
Dealer as soon as possible.
Driving
•Drive carefully for the first few
miles until the engine reaches its
normal operating temperature.
• Speed is expensive.
• “Snappy” driving uses a lot of
fuel: drive with a “light right
foot”.• Take your foot off the accelerator
pedal to slow down rather than
use the brakes wastefully and
judge the road well in advance.
• Avoid fierce acceleration.
•Donotoverrevtheengineinthe
intermediate gears.
Always use the highest ratio
possible without labouring the
engine.
On versions with an automatic
transmission, it is preferable to
keep your the gear lever inD.
•Donottrytomaintainthesame
speed up a hill; accelerate no
more than you would on the level.
Keep your foot in the same
position on the accelerator pedal.
• Double declutching and
accelerating before switching off
are superfluous actions in
modern cars.
• Bad weather, flooded roads
Do not drive through
floods if the depth of
water is above the lower
edge of the wheel rims.

General hints
•Electricity is “fuel”; switch off all
the electrical units which are not
really needed.
However,(with safety always in
mind), keep your lights on when
the visibility is bad (see and be
seen).
• Try to use the air vents. Driving
with the windows open will
increase the use of fuel by 4%.•For vehicles with air
conditioning,theextrafuel
consumed in urban cycle can be
as high as 2 litres per 100 km:
switch the system off when it is
not needed.
• Never fill the fuel tank right to the
brim as this is wasteful.
• Do not leave an empty roof rack in
position.
• It is better to fit a trailer for bulky
objects.
• When towing a caravan, fit a wind
deflector and adjust it carefully.
• Avoid using the car for
door-to-door calls (short journeys
with long waits in between)
because the engine never reaches
its normal operating temperature.
Trytogroupyourcalls.
Tyres
•Inflation pressures which are
toolowmayincreasefuel
consumption.
• The use of non-recommended
tyres may also increase fuel
consumption.

ENVIRONMENT
Your vehicle has been designed
with the aim of caring for the
environment.
• The majority of versions are
equipped with a depollution
system including acatalytic
converter,alambda sensorand
anactive carbon filter.(The
active carbon filter prevents
vapour from the petrol tank being
released into the open air.)
• These vehicles operate with
unleaded fuel only.
•The majority of components in
your vehiclecan be recycledand
your vehicle already contains
recycled materials.
• 95% of the plastic components in
your vehicle are marked with a
symbol which allows the
principle component material to
be identified. These markings
mean that parts removed can be
sorted more easily, thus
optimising the recycling of each
of them.In addition to this, your vehicle
meets the requirements laid down
in European legislation relating to
environmental protection.
Make your contribution towards
protection of the environment too!
Do not dispose of parts replaced in
thecourseofroutinevehicle
maintenance (battery, oil filter, air
filter, etc.) and oil containers (empty
or full of used oil, etc.) with
household waste.
Dispose of it through specialist
organisations. In all cases, comply
with local legislation.

TYRE PRESSURE MONITORING SYSTEM
This system continuously monitors
the tyre pressures.
Tyre pressures should be adjusted
when the tyres are cold.
If tyre pressures cannot be checked
when the tyres arecold,assumean
increase of0.2to0.3bar.
Never deflate a hot tyre.
This function is an
additional driving aid.
However, the function
does not take the place of
the driver. It cannot, therefore,
under any circumstances replace
the vigilance or the
responsibility of the driver.
Check the tyre pressures,
including the emergency spare
wheel, once a month.
Operating principle
Each wheel (except the emergency
spare wheel) has a sensor,
implanted in the inflation valve
which periodically measures the
tyre pressure.
The driver is constantly informed of
the correct tyre pressures and
possible variations on displayA
and the instrument panel.

TYRE PRESSURE MONITORING SYSTEM(continued)
Non-interchangeability of
wheels
Each of the sensors
integrated in the valve1
is devoted to a single
wheel: under no
circumstances should you swap
the wheels.
There is a risk of false
information leading to serious
consequences.To mark the correct position of the
wheel, see the colour of the ring2
(after cleaning, if necessary) on each
valve:
-C: yellow ring
-D:blackring
-E:redring
-F:greenring
Fitting tyres
(replacing tyres or fitting winter
tyres)
As there are special precautions to
be taken when replacing tyres, we
advise you to consult your Renault
Dealer.
Reading the tyre pressures on
the instrument panel
(if fitted)
Once the car's tyre pressures have
been checked, warning messages on
the instrument panel are updated
once you exceed 15 mph (25 km/h).
Commercially available pressure
gauges will show variances in their
measurement of pressure (known as
tolerance).
