MAINTENANCE AND ANTIPOLLUTION ADVICE
Your vehicle complies with criteria for
recycling and recovering vehicles at the
end of their service life, which entered
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.
Maintenance
It is important to remember that fail-
ure to respect antipollution regulations
could lead to legal action being taken
against the vehicle owner.In addition, replacing engine, fuel
supply system and exhaust compo-
nents with parts other than those origi-
nally recommended by the manufac-
turer may alter your vehicle so that it
no longer complies with anti-pollution
regulations.
Have your vehicle adjusted and
checked by an authorised 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
– Spark plugs:
for optimum condi-
tions of use, output 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
authorised dealer for this.
– Air filter, fuel filter: a choked ele-
ment will reduce efficiency. It must
be replaced.
– Ignition and idle speed: no adjust-
ment is needed.
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
an authorised dealer as soon as pos-
sible.

2.26
ENVIRONMENT
Emissions
Your vehicle has been designed to
emit fewer greenhouse gases (CO2)
while in use, and therefore to consume
less fuel (e.g. 140 g/km, equivalent to
1494.6 mpg (5.3 l/100 km) for a diesel
vehicle).
Our vehicles are also equipped with a
particle filter system including a cata-
lytic converter, an oxygen sensor and
an active carbon filter (the latter pre-
vents vapour from the fuel tank being
released into the open air).
For certain diesel vehicles, this system
also has a particle filter to reduce the
volume of soot particles emitted.
Please make your own
contribution towards
protecting the environment
too
– Worn parts replaced in the course of routine vehicle maintenance (vehi-
cle battery, oil filter, air filter, batter-
ies, etc.) and oil containers (empty or
filled with used oil) must be disposed
of through specialist organisations. – At the end of the vehicle’s service
life, it should be sent to approved
centres to ensure that it is recycled.
– In all cases, comply with local legis- lation.
Recycling
Your vehicle is 85% recyclable and
95% recoverable.
To achieve these objectives, many of
the vehicle components have been de-
signed to enable them to be recycled.
The materials and structures have
been carefully designed to allow these
components to be easily removed and
reprocessed by specialist companies.
In order to preserve raw material re-
sources, this vehicle incorporates nu-
merous parts made from recycled plas-
tics or renewable materials (vegetable
or animal-derived materials such as
cotton or wool).
Your vehicle has been designed with
respect for the environment in mind for
its entire service life: during production,
use and at the end of its life.
This commitment is illustrated by the
Renault eco² signature.Manufacture
Your vehicle has been manufactured at
a factory which complies with a policy
to reduce the environmental impact
on the surrounding areas (reduction of
water and energy consumption, visual
and noise pollution, atmospheric emis-
sions and waste water; sorting and re-
using waste).

2.27
TYRE PRESSURE MONITORING SYSTEM (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 displays the current pres-
sures on the instrument panel 1 and
alerts the driver in the event of insuffi-
cient pressure.
Resetting the standard level
for the tyre pressures
This should be done:
– when the standard tyre pressure needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after swapping a wheel (however this practice is not recommended);
– after changing a wheel.
It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).
21
Resetting procedure
With the ignition on:
– repeatedly and briefly press con- trol 2 to select the tyre pressure dis-
play and, depending on the vehicle,
the “Tyre pressure” function;
– press and hold (around 3 seconds) the button 2 to launch the reset. The
flashing tyres followed by the mes-
sages “Learning TP initiated” and
then “Tyres location in progress” in-
dicates that the reset request for the
tyre pressure reference value has
been acknowledged.
Reset can take several minutes of driv-
ing.
If the resetting is followed by short
trips, the message “Tyres location in
progress” can remain displayed after
successive restarts.
Note: the standard tyre pressure
cannot be less than that recommended
and indicated on the door frame.

You can also perform a reset from
the multimedia screen 3 if your vehi-
cle is fitted with a navigation system.
Select Vehicle”,”Tyre pressure”.

The display 1 and the warning light 4
 on the instrument panel warn
you of any tyre pressure faults (flat tyre,
punctured tyre, system fault, etc.).
“Puncture”
A wheel B is shown, depending on the
vehicle, in red or white accompanied
by the warning light 4
 fixed, the
message “Puncture” and a beep.
This message appears along with the
® warning light. They indicate that
the affected wheel is punctured or se-
verely underinflated. Replace it or con-
tact an approved dealer if it is punc-
tured. Top up the tyre pressure if the
wheel is deflated.
“Check tyre pressure sensors”
A wheel A disappears, the warning
light 4
 flashes for several sec-
onds then comes on continuously and
the message “Check tyre pressure sen-
sors” appears.
This message appears along with the
© warning light. They indicate that
at least one wheel is not fitted with sen-
sors (e.g. emergency spare wheel).
Otherwise, consult an authorised
dealer.
“Adjust tyre pressure”
A wheel B is shown, depending on the
vehicle, in orange or white accompa-
nied by the warning light
4
 fixed
and the message “Adjust tyre pres-
sure”. They indicate that a wheel is de-
flated.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light 4
 goes off after
a few minutes’ driving.

Tyre repair product and
inflation kit
Because the valves are specially de-
signed, only use equipment approved
by the approved network. Please refer
to “Tyre inflation kit” in Section 5.
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, hubcaps, etc.).
Please see the information on “Tyres”
in Section 5.
Contact an approved Dealer to fit new
tyres and to find out about available ac-
cessories compatible with the system
and available from your dealer net-
work: the use of any other accessory
could affect the correct operation of the
system or damage a sensor.
Emergency spare wheel
If the vehicle is equipped with an emer-
gency spare wheel, it will not have a
sensor.
TYRE PRESSURE MONITORING SYSTEM (3/3)
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.
“Tyres location in progress”
This message “Tyres location in
progress” appears when driving if one
or more wheels have been fitted with
sensors not recognised by Renault.
Consult an approved dealer
Readjustment of tyre
pressures
The tyre pressures should be ad-
justed when cold (please refer to the
label located on the edge of the driver’s
door). If the tyre pressures cannot be
checked when the tyres are cold, the
recommended pressures should be in-
creased by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.
This function is an addi-
tional driving aid.
The function does not take
the place of the driver. It
cannot, therefore, under any cir-
cumstances replace the vigilance
or the responsibility of the driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.

2.30
DRIVER CORRECTION DEVICES AND AIDS (1/10)ABS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi-
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par-
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
– ABS (anti-lock braking system);
– ESC
(electronic stability control)
with understeer control and trac-
tion control;
– emergency brake assist;
– active emergency braking;
– hill start assistance;
– rear wheel steering.
Other driving assistance systems are
detailed on the following pages.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu-
late the force applied in the braking
system.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
The functions do not take the place
of the driver. They do not increase
the vehicle’s limits and should
not encourage you to drive more
quickly. Therefore, they can under
no circumstances replace the vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

2.31
DRIVER CORRECTION DEVICES AND AIDS (2/10)
Operating faults:
–
© and x lit up on the in-
strument panel accompanied by the
messages “Check ABS”, “Check
braking system” and “Check ESC”:
this indicates that the ABS, the ESC
and the emergency brake assist are
disabled. Braking is always ena-
bled;
–
x, D, © and ®
lit on the instrument panel accom-
panied by the message “Braking
system fault”: this indicates a fault
with the braking system.
In both cases, consult an approved
dealer.
Your braking systems
are partially operational.
However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow. Switch off the engine and do
not restart it. Contact an approved
Dealer.

2.32
Electronic stability control
ESC with understeer control
and traction control
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, indicator 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).
Traction control
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
© and  appear
on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated. Consult an
authorised dealer.
