DRIVING ADVICE, ECO-DRIVING

(5/5)

Advice on use
– Opt for ECO mode.

– Electricity is fuel; switch off all the

electrical components which are

not really needed. However (safety

first), keep your lights on when the

visibility is bad (“see and be seen”).

– Use the air vents. Driving with the

windows open at 60 mph (100 km/h)

will increase fuel consumption by

4%.

– Never fill the fuel tank right to the

brim to avoid overflow.

– In vehicles fitted with air condi-

tioning, it is normal to observe an

increase in fuel consumption (espe-

cially in urban conditions) when it is

used. For vehicles fitted with manual

air conditioning, switch off the system

when it is not required.
Recommendations for reducing

consumption and therefore help-

ing to preserve the environment:
If the vehicle has been parked in the

sun, open the doors for a few mo-

ments to let the hot air escape before

starting the engine.

– Do not leave an empty roof rack

fitted to the vehicle.

– It is better to fit a trailer for bulky ob-

jects.

– When towing a caravan, fit a wind

deflector and adjust it carefully.

– Avoid using the car for door-to-door

calls (short journeys with long waits

in between) because the engine

never reaches its normal operating

temperature.

Tyres
– An underinflated tyre increases fuel

consumption.

– Opt for the highest speed pressure

or the pressure recommended to op-

timise fuel consumption indicated

on edge of the driver’s door (please

refer to the information on “Tyre infla-

tion pressure” in Section 4).

– The use of non-recommended tyres

can increase fuel consumption.

2.25

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.

This 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.).

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”.

TYRE PRESSURE MONITORING SYSTEM

(2/3)

Display

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.

For your safety, the warning
light

requires you

to stop immediately as soon

as traffic conditions allow.

The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be detected by the

system.

2.29

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).

Operating faults:

–

and

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;

–

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.

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.

Hazard warning lights switching on

Depending on the vehicle, these may

light up in the event of sudden decel-

eration.

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.

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.

2.34

DRIVER CORRECTION DEVICES AND AIDS

(5/10)

If the driver depresses the brake pedal

and the system still detects a risk of col-

lision, the brake force is increased.
If the driver fails to react following

an alert of an imminent collision, the

system activates the brakes.

Active emergency braking

Using the sensor 1, the system calcu-

lates the distance separating the vehi-

cle from the one in front and alerts the

driver if there is a risk of a front-end col-

lision. The driver can then brake the ve-

hicle to limit the damage arising from a

collision.
Note: Make sure that the sensor 1 is

not obscured (by dirt, mud, snow, etc.).

Operation
When driving (speed between 19 and

87 mph (30 and 140 km/h) or depend-

ing on the vehicle, 93 mph (150 km/h)),

if there is a risk of collision with the ve-

hicle in front, depending on the vehicle:

– the warning light



is displayed

in red on the instrument panel, ac-

companied by a beep;

or
– the indicator 2 is displayed in red on

the instrument panel and, depending

on the vehicle, on the head up dis-

play, accompanied by a beep.

The system only detects vehicles

driving in the same direction of traf-

fic. The system cannot detect mo-

torcycles because of the difficulty in

forecasting their trajectory.

(7/10)

Active emergency braking

This function is an additional driving aid. This function is not under any

circumstances intended to replace the due care and attention of the

driver, who should at all times be in control of the vehicle.

System servicing/repairs
– In the event of an impact, the sensor alignment may become changed, and its

operation will consequently be affected. Deactivate the function, then consult

an authorised dealer.

– Any work in the area where the radar is located (repairs, replacements, touch-

ing up of paintwork) must be carried out by a qualified professional.

Only an authorised dealer is qualified to service the system.

In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such as:
– a complex environment (metal bridge, etc.);
– poor weather conditions (snow, hail, black ice, etc.).
Risk of inadvertent braking.

Operating faults
When the system detects an operating

fault, the



warning light lights up

on the instrument panel, with the mes-

sage “Active braking disconnected”.
There are two possibilities:
– The system is temporarily experienc-

ing difficulties (for example: sensor

obscured by dirt, mud, snow etc.);

in this case, park the vehicle and

switch off the engine. Clean the de-

tection zone of the radar. When you

next start the engine, the warning

light and the message go out;

– If this is not the case, this may arise

from another cause; contact an

Approved Dealer.

DRIVER CORRECTION DEVICES AND AIDS

(8/10)

Active emergency braking

Limitation of the system operation
– The system will only respond to vehicles which are moving or which have been sensed as moving.

–  A vehicle travelling in the opposite direction will not trigger any alert or any action on the system operation.
–  The sensor area should be kept clean and free of any modifications in order to ensure the proper operation of the system.
–  The system cannot respond to small vehicles such as motorbikes or bicycles as effectively as to other vehicles.

Deactivating the function
You must disable the function if:
–  the brake lights are not functioning;
–  the front of the vehicle has undergone an impact or been damaged;
–  the vehicle is being towed (breakdowns).

Halting the function
You can halt the active braking function at any time by tapping the accelerator pedal or by turning the steering wheel in a avoid-

ance manoeuvre.
If the driver notices any unusual behaviour in the system, please consult an authorised dealer.

2.38

DRIVER CORRECTION DEVICES AND AIDS

(9/10)

Hill start assistance

Depending on the gradient of the in-

cline, this system assists the driver

when starting on a hill. It prevents the

vehicle from rolling backwards by au-

tomatically applying the brakes when

the driver lifts his/her foot off the brake

pedal to depress the accelerator pedal.

System operation
It only operates when the gear lever is

in a position other than neutral (other

than N or P for automatic transmis-

sions) and the vehicle is completely

stationary (brake pedal depressed)

The system holds the vehicle for ap-

proximately 2 seconds. The brakes are

then released (the vehicle will move ac-

cording to the slope).

The hill start assistance

system cannot completely

prevent the vehicle from

rolling backwards in all sit-

uations (extremely steep gradients,

etc.).

In all cases, the driver may depress

the brake pedal to prevent the vehi-

cle from rolling backwards.

The hill start assistance function

should not be used for prolonged

stops: use the brake pedal.

This function is not designed to im-

mobilise the vehicle permanently.

If necessary, use the brake pedal to

stop the vehicle.

The driver must remain particularly

vigilant when driving on slippery or

low-grip surfaces and/or on hills.

Risk of serious injury.

Rear wheel steering

On equipped vehicles, this system,

when the vehicle is being driven, steers

the rear wheels according to driving

conditions: at low speed this system

offers manoeuvrability, at higher speeds

it optimises stability.
When driving at low speeds, the rear

wheels steer in the opposite direction to

the front wheels (figure A) to increase

the vehicle’s manoeuvrability. This is

used when driving in towns, on winding

roads, during parking manoeuvres, etc.

When driving at higher speeds, the rear

wheels steer in the same direction as

the front wheels (figure B) to optimise

the vehicle’s stability. This is useful

when changing lanes or when corner-

ing etc.
Note: The system configuration (agil-

ity, etc.) depends on the mode selected

in the “Multi-sense” menu (please refer

to the information on “Multi-sense” in

Section 3).

Operating faults
– If the

warning light, together

with the message “Check power

steering”, is displayed on the instru-

ment panel: please contact an au-

thorised dealer.

– If the warning light

, together

with the message “Power steering

fault”, is displayed on the instrument

panel, this indicates a fault in the

system.

requires you to stop

as soon as traffic conditions

allow. Contact an approved

Dealer.

An impact to the underside of the

vehicle (e.g.: striking a post, raised

kerb or other street furniture) may

result in damage to the vehicle (e.g.:

deformation of an axle).
To avoid any risk of accident, have

your vehicle checked by an ap-

proved Dealer.
