SPECIAL FEATURES OF DIESEL VEHICLES FITTED WITH AN EXHAUST PARTICLE FILT\
ER
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 with
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 vapour
condensing in it and accumulating
at the bottom of the tank.
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.
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.

normal operating temperature,

the vehicle is stationary.

drive with a “light right foot”.
Exhaust gas monitoring system
The exhaust gas monitoring system
will detect any malfunctioning of
the vehicle’s exhaust gas anti-
pollution system.
If this system malfunctions, toxic
substances may be released into the
atmosphere or damage may occur.
äThis instrument panel
warning light shows any
system faults:
This comes on when the ignition is
switched on and goes out after three
seconds.
- If it comes on continuously, contact 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.

Always use the highest gear
possible without labouring the

On versions with automatic
transmissions, it is preferable to
keep the gear lever in position D.

TYRE PRESSURE MONITOR (continued)
Emergency spare wheel
The spare wheel has no sensor, and
cannot be recognised by the system.
When it is fitted in the place of
another wheel, the system then
detects an operation fault.
Replacing wheels/tyres
This system requires special
equipment (wheels, wheel trims, etc.).
Contact your RENAULT Dealer to
find out about accessories
compatible with the system and
which may be purchased from
RENAULT outlets: the use of any
other accessory could affect the
correct operation of the system.
Tyre repair aerosols
Because the valves are specially
designed, use only aerosols
approved by Renault’s Technical
Department.
Display
Display 1on the instrument panel
informs you of any tyre pressure
faults (flat tyre, punctured tyre,
system fault, etc.). The following pages show the
possible warning lights, symbols
and messages.

A shaded wheel B, indicates a
deflated tyre.

inflate all fourtyres to motorway
pressure (refer to the tyre pressure
table).
"No tyre sensors" or "Tyre sensor

One wheel A, disappears, indicating
that the sensor on this wheel is
missing or faulty (e.g. if the
emergency spare wheel is fitted
etc.).

ELECTRONIC STABILITY PROGRAM: ESP WITH UNDERSTEER CONTROL
When the function begins to
operate, warning light Aflashes to
warn you.
If the warning light comes on
accompanied by the “ASR/ESP
deactivated” message when the
engine is started, slowly turn the
steering wheel from lock to lock to
reinitialise the system.
Understeer control
This system optimises the operation
of the ESP in the case of pronounced
understeering (loss of front axle
roadholding).
Operating faults
If the system detects an operating
fault, the message “Check traction
control” or “ESP/ASR not
functioning” is displayed on the
instrument panel display along with
indicator light and indicator
light A.
Contact your RENAULT Dealer.
This system helps to keep control of
the vehicle in critical driving
situations (avoiding an obstacle, loss
of grip when cornering, etc.) and
works in conjunction with the
understeer control system.
Operating principle
A sensor in the steering wheel
detects the direction selected by the
driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares the direction
selected by the driver and the actual
direction of the vehicle and corrects
this as necessary by applying the
brakes selectively and/or acting on
the engine power.
2.19
This function is an
additional aid in case of
critical driving conditions
to enable the vehicle
behaviour to be adapted to suit
the driving conditions.
However, the function does not
take the place of the driver. It
does not increase the vehicle’s
limits and should not encourage
you to drive more quickly.
Therefore, it can under no
circumstances replace the
vigilance or responsibility of the
driver when manoeuvring the
vehicle (the driver must always
be ready for sudden incidents
which may occur when driving).

TRACTION CONTROL: ASR
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and
slows down their over-rotation.
If a wheel is starting to spin, the
system brakes automatically until
the drive supplied becomes
compatible with the level of grip.The system also adjusts the engine
speed to the grip available under the
wheels, independently of the
pressure exerted on the accelerator
pedal.
When the function begins to
operate, warning light
Aflashes to
warn you.
This system helps to limit skidding
on drive wheels and to control the
vehicle when pulling away or
accelerating.

TRACTION CONTROL: ASR (continued)Operating faults
If the system detects an operating
fault, the message Check traction
control or ESP/ASR not functioning
is displayed on the instrument panel
display along with the
warning light and warning light A.
Contact your RENAULT Dealer.
If the warning light comes on
accompanied by the “ASR
deselected” message when the engine
is started, slowly turn the steering
wheel from lock to lock to reinitialise
the system.
Disabling the function also disables
the ESP function.
Correct this as soon as possible by
pressing switch 1again.
The function is reactivated
automatically when the ignition is
switched on or when a speed of
approximately 30 mph (50 km/h) is
exceeded.
It is impossible to deselect this
function when travelling above a
threshold of approximately 30 mph
(50 km/h).
Disabling the function
In some situations (driving on very
wet ground: snow, mud, etc. or
driving with snow chains fitted), the
system may reduce the engine
output to limit wheelspin. If this is
not required, it is possible to
deactivate the function by pressing
switch 1.
The “ESP/ASR deactivated” message
is displayed on the instrument panel
along with warning light Ato inform
you.

ANTI-LOCK BRAKING SYSTEM: ABS (continued)
One of two situations may arise if
there is a fault in the ABS system:
1 - Orange warning lights

and light up on the
instrument panel.
Braking is still performed, but
without the ABS system. Contact
a RENAULT Dealer as soon as
possible.
The braking modulation provided
by the ABS is independent of the
effort applied to the brake pedal. In
an emergency, apply firm and
continuous pressure to the brake
pedal There is no need to pump it
repeatedly.
2.23
2 - The orange x
warning light and the red
dbrake fault warning
light accompanied by and
ûand, depending on vehicle,
the message Brake fault are
illuminated on the instrument panel.
This indicates that both the braking
system and the ABS system are
faulty. Your braking systems are only
partially operational. However, it is
dangerous to brake suddenly and it
is essential to stop immediately, as
soon as traffic conditions allow.
Contact a RENAULT Dealer.

EMERGENCY BRAKE ASSIST
This system is complementary to
ABS and helps reduce vehicle
stopping distances.
Operating principle
The system is for detecting an
emergency braking situation. In this
case, the braking assistance
immediately develops maximum
power and may trigger ABS
regulation.
ABS braking is maintained as long
as the brake pedal is not released.
Hazard warning lights switching
on
Depending on the vehicle, these
may light up in the event of sudden
deceleration.This function is an
additional aid in case of
critical driving conditions
to enable the vehicle
behaviour to be adapted to suit the
driving conditions.
However, the function does not take
the place of the driver. I t does not
increase the vehicle’s limits and
should not encourage you to drive
more quickly.
Therefore, it can under no
circumstances replace the vigilance
or responsibility of the driver when
manoeuvring the vehicle (the driver
must always be ready for sudden
incidents which may occur when
driving).
