2018 RENAULT TWINGO sensor

2.16
ENVIRONMENT
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 of
the manufacturer 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).
Emissions
In usage phase, your vehicle was de-
signed to emit fewer greenhouse gases
(CO2) and therefore consume less fuel.
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).
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).

TYRE PRESSURE LOSS WARNING (6/9)
SYSTEM B
Operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure while driving.
Warning light
 1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punctu-
red tyre, etc.).
1
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.).
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.

2.24
TYRE PRESSURE LOSS WARNING (8/9)
SYSTEM B (cntd.)
Inflate tyres
The
 1 warning light comes on
(not flashing).
This indicates that at least one tyre is
flat.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light
 1 goes off after
a few minutes’ driving.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.
Puncture
Warning light
 1 comes on steady,
accompanied by a beep and warning
light
®.
They indicate that at least one wheel
is punctured or severely underinfla-
ted. Replace it or contact an authorised
dealer if it is punctured. Top up the tyre
pressure if the wheel is deflated.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow.
Check tyre sensors
The warning light
 1 flashes for
several seconds, then stays on, along
with the warning light
©.
These indicate that at least one of the
sensors is defective or missing. In other
cases, contact an authorised dealer.

2.25
SYSTEM B (cntd.)
Readjustment of tyre pressures
The tyre pressures must be adjusted
when cold (please refer to the label lo-
cated on the edge of the driver’s door).
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.
TYRE PRESSURE LOSS WARNING (9/9)
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. When it is fitted on the vehicle,
the warning light
 flashes for sev-
eral seconds, then stays on, together
with the warning light
©.
Tyre repair product and inflation kit
Because the valves are specially desi-
gned, only use equipment approved by
the approved network. Please refer to
“Tyre inflation kit” in Section 5.

2.27
Electronic stability control
(ESC) with understeer
control, traction control and
assistance with side winds
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.).
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.
DRIVER CORRECTION DEVICES AND AIDS (2/4)
Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
Assistance with side winds
This system optimises the action of the
ESC and also helps to control the vehi-
cle in case of variation of side winds.
It helps maintain the vehicle trajectory
through the use of the brakes.
If the system is activated, the indicator
light
 may flash on the instrument
panel.
Traction control
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
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 warning lights
© and
 appear on the instrument panel.
In this case, the ESC and traction con-
trol system are deactivated.
Consult an approved dealer.

Electrical equipmentPOSSIBLE CAUSESWHAT TO DO
Traces of condensation in the lights
and headlights. Traces of condensation may be a nat-
ural phenomenon caused by varia-
tions in temperature and humidity.
In this case, the traces will disappear
slowly once the lights are switched
on.
The front seat belt reminder light
comes on when the seat belts are
fastened. An object is stuck between the floor
and the seat and is disrupting the op-
eration of the sensor. Remove all objects from underneath the
front seats.
