SPECIAL FEATURES OF DIESEL VEHICLES FITTED WITH AN EXHAUST PARTICLE FILTER
1
The warning light comes on
to indicate a filter saturation risk.
To clean the particle filter, we
recommend that you drive the
vehicle as soon as possible until the
warning light goes out, at an average
speed of 48 mph (80 km/h) provided
that traffic conditions and the speed
limit allow it.
As an indication, cleaning should
last about 20 minutes in this case.

If the message "Check emission
control" or "Regenerate particle
filter" is displayed alongside the
warning light, refer to your
RENAULT dealer as soon as possible.
Do not park the vehicle or
run the engine in locations
where combustible
substances or materials
such as grass or leaves can come
into contact with the hot exhaust
system.
When driving, depending on the
grade of fuel 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.
Diesel engine speed
Diesel engines are fitted
injection equipment which prevents
the engine from over-revving,
irrespective of the gear engaged.
Precautions to be taken in winter
To avoid any faults in icy weather:
- ensure that the battery is always
fully charged;
- always keep the fuel tank relatively
full to avoid water
condensing in it and accumulating
at the bottom of the tank.
