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

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.
