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.

Advice: antipollution and fuel economy
aDVICe: antipollution, fuel economy and driving (1/3)
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life which will come
into force in 2015.
Some parts of your vehicle have there-
fore been designed to facilitate future
recycling.
These parts are easy to remove so
that they can be recovered and reproc-
essed by recycling companies.
By virtue of its design, moderate fuel
consumption and initial settings, your
vehicle also conforms to current anti-
pollution regulations. The manufac -
turer is actively striving to reduce pol -
lutant exhaust gas emissions and to
save energy. But the fuel consumption
of your vehicle and the level of pollutant
exhaust gas emissions are also your
responsibility. Ensure that it is main -
tained and used correctly.aiding fuel economy
Depending on the vehicle, in order to
optimise consumption, an indicator light
on the instrument panel will inform you
of the best moment to upshift or down -
shift gears:
\ shift up a gear;
[ shift down a gear.
Maintenance
It is important to remember that failure to
respect antipollution regulations could
lead to legal action being taken against
the vehicle owner. In addition, replacing
engine, fuel supply system and exhaust
components with parts other than those
originally recommended by the manu -
facturer may alter your vehicle so that
it no longer complies with antipollution
regulations. Have your vehicle adjusted and
checked by an approved Dealer, in ac-
cordance with the instructions given in
your maintenance schedule: they will
have all the equipment necessary for
ensuring that your vehicle is maintained
to its original standard.
engine adjustments–
ignition: this does not require ad -
justment.
– spark plugs: for optimum fuel econ-
omy, efficiency and performance
the specifications laid down by our
Design Department must be strictly
applied.
If the spark plugs have to be
changed, use the make, type and
gap specified for your vehicle’s
engine. Contact an approved dealer
for this.
– idle: this does not require adjust -
ment.
– air filter, diesel filter: a clogged ele-
ment reduces performance. It must
be replaced.

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.

Système de surveillance de pression des pneumatiques (X91 - B91 - K9\
1 - Renault)
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.

Disabling the aSR 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 wheel -
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “ Traction control off ” is
displayed on the instrument panel to
inform you.
Traction control (ASR) offers additional
safety; it is recommended that you do
not drive with the function disabled.
Correct this as soon as possible by
pressing switch 1 again.
Note: The function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.
emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
operating principle
The system is for detecting an emer -
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig -
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.

operating faults
When the system detects an operat -
ing fault the message “ Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma -
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you
release it, the system may be trig -
gered;
– if you do not use the accelerator, the
system will not be triggered.

Driving in automatic mode
Select position D. In most traffic con -
ditions, you will not have to touch the
gear selector lever again: the gears will
change automatically at the right time
and at the most suitable engine speed
because the automatic system takes
into account the vehicle load and road
contour and adjusts itself to the particu-
lar driving style you have chosen.
economical driving
When driving, always leave the lever
in position D, keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
accelerating and overtaking
Depress the accelerator pedal firmly
and fully (so that it goes beyond the
kickdown point).
this will enable you to change down
to the optimum gear within the
engine range.
