The following operating conditions:
– driving for long periods when the low
fuel level warning light is lit;
– using leaded petrol;
– using fuel or lubrication additives
which are not approved.
Or operating faults such as:
– faulty ignition system, running out of
fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power,
as they may cause the catalytic con -
verter to overheat and thus reduce its
efficiency, or damage it irreparably
and cause heat damage to the vehi-
cle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved Dealer.
These faults may be avoided by regu
-
larly taking your vehicle to an approved
Dealer at the intervals specified in the
Maintenance Service Booklet.
Starting problems
To avoid damaging the catalytic con -
verter, do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
starting fault.
If the fault cannot be identified, do not
keep trying to start the engine, but con-
tact an approved Dealer.
Do not park the vehicle or
run the engine in locations
where combustible sub -
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.

Special features of diesel versions
SPeCIaL FeatUReS oF DIeSeL VeRSIoNS
Diesel engine speed
Diesel engines are fitted with injection
equipment which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollu -
tion” is displayed on the instrument
panel accompanied by the
Ä and
©warning light; consult an ap -
proved dealer straight away.
When driving, depending on the fuel
grade 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.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: see information
on the “fuel tank” in section 1 before re-
starting the engine.
Do not park the vehicle or
run the engine in locations
where combustible sub -
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully
charged,
– always keep the diesel tank rela -
tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

aSSISteD P aRKING BRaKe (continued)
It is therefore essential to
immobilise the vehicle by
engaging first gear (manual
gearbox) or position P (au -
tomatic gearbox). If the slope re -
quires it, chock the vehicle.
Versions with an automatic
gearbox
For safety reasons, automatic release
is deactivated when the driver’s door
is open or not shut properly and the
engine is running (in order to prevent
the vehicle from moving without the
driver). A beep draws your attention to
this and the message “release manu -
ally” is displayed on the instrument
panel.
If no lights or sounds are
apparent, this indicates
a fault in the instrument
panel. This indicates that it
is essential to stop immediately
(as soon as traffic conditions
allow). Ensure that the vehicle is
correctly immobilised and contact
an approved Dealer.Never leave your vehicle
without moving the selec -
tor lever to position P or N.
This is because when the
vehicle is stationary with the engine
running and a gear engaged, the
vehicle may begin to move if you
accelerate.
there is a risk of accidents.

aDVICe: antipollution, fuel economy and driving (2/3)
– Avoid sudden acceleration.
– Brake as little as possible. If you an-
ticipate an obstacle or bend in ad -
vance, you may then simply release
the accelerator pedal.
– Do not try to maintain the same
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 unnecessary
in modern vehicles.
– Bad weather, flooded roads:
Do not drive through floods
if the water is above the
lower edge of the wheel
rims.
Driving– Drive carefully for the first few miles
until the engine reaches its normal
operating temperature, rather than
let it warm up while the vehicle is sta-
tionary.
– Speed is expensive.
– Sporty driving uses a lot of fuel: drive
with a light right foot.
– Do not overrev the engine in the in-
termediate gears.
Always use the highest gear possi -
ble without labouring the engine.
On versions with an automatic gear-
box, it is preferable to keep the gear
lever in position D.
exhaust gas monitoring
system
The exhaust gas monitoring system will
detect any operating faults in the vehi-
cle’s antipollution system.
If this system malfunctions, toxic sub -
stances may be released into the at -
mosphere or damage may occur.
ÄThis warning light on the in -
strument panel will indicate if
there are any faults in the system:
This lights up when the ignition is
switched on and goes out when the
engine is started.
– If it lights up continuously, consult an
approved Dealer as soon as possi -
ble;
– if it flashes, reduce the engine speed
until the light stops flashing. Contact
your approved dealer as soon as
possible.
obstructions to the driver
On the driver ’s side, only
use mats adapted to the ve-
hicle that attach to the pre-
installed parts, and regularly check
their mounting. Do not place several
mats on top of each other.

ENG_NU_939-3_D91_Renault_2
This system monitors the tyre pressure.
Information is displayed:
– with the ignition on, when scrolling
through the trip computer and warn-
ing system information by pressing
control 2 (refer to the information
on the “trip computer and warning
system” in Section 1);
– or if there is a fault when driving
(refer to the following page to find out
more about the warning messages).
Tyre pressure monitor
This function is an addi -
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig -
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
tyRe PReSSURe MoNItoR (1/3)
If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure.
The system informs the driver via the
trip computer and warning system 1
that the tyres are sufficiently inflated
and warns if they are underinflated or
leaking.
t he tyre pressure can be adjusted
when cold (refer to the information on
“Tyre pressures”).
If tyre pressures cannot be checked
when the tyres are cold, the recom -
mended pressures must be increased
by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.1

Changing a wheel
The system may take sev -
eral minutes depending on
use for the new wheel po -
sitions and pressures to be recog -
nised; check the tyre pressures after
all operations.

and traction control aSR
electronic stability control eSC
This system helps you to keep control
of the vehicle in critical driving condi -
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
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 driver input to
the actual trajectory of the vehicle and
corrects the trajectory, if necessary, by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, warning light
 flashes on the instrument panel. Understeer control
This system optimises the action of the
ESC in the case of pronounced under
-
steer (loss of front axle road holding).
t raction control (aSR)
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
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 slip, the system brakes au -
tomatically until the drive supplied be -
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal. operating faults
When the system detects an operat
-
ing fault the message “Check ESC” and
warning light
© appear on the in-
strument panel. In this case, the ESC
and ASR are deactivated.
Consult an approved dealer.
