Load limiter
Above a certain severity of impact, this
mechanism is used to limit the force of
the belt against the body so that it is at
an acceptable level.
Anti-submarining air bag
Located on each of the front seats, it
deploys in order to prevent the occu -
pant from sliding under the seat belt.
Air bags for driver and front
passenger
Fitted to the driver and passenger side.
Depending on the vehicle, the pres -
ence of this equipment is indicated by
the word “air bag” on the steering wheel
and dashboard (air bag zone A ) and
a symbol on the lower section of the
windscreen.
Each air bag system consists of:
– an air bag and gas generator fitted
on the steering wheel for the driver
and in the dashboard for the front
passenger;
– an electronic unit for system monitor-
ing which controls the gas generator
electrical trigger system;
– a single indicator light
å on the
instrument panel;
– remote sensors.
A
The air bag system uses
pyrotechnic principles. This
explains why, when the air
bag inflates, it will gener -
ate heat, produce smoke (this does
not mean that a fire is about to start)
and make a noise upon detonation.
In a situation where an air bag is
required, it will inflate immediately
and this may cause some minor, su-
perficial grazing to the skin or other
problems.

emissions
Your vehicle has been designed to
emit fewer greenhouse gases (CO2)
while in use, and therefore to consume
less fuel (eg. 140 g/km, equivalent to
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 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).

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.

Parking distance control
This function is an additional aid that indicates the distance between the
vehicle and an obstacle whilst reversing, using sound signals.
Under no circumstances should it replace the driver’s care or responsibil -
ity whilst reversing.
The driver should always look out for sudden hazards during driving: always
ensure that there are no moving obstacles (such as a child, animal, pram or bi-
cycle, etc.) or small, narrow objects such as stones or posts in your path when
manoeuvring.
operating principle
Ultrasonic detectors, installed in the
front or rear bumper depending on the
vehicle, measure the distance between
the vehicle and an obstacle whilst re -
versing.
This measurement is indicated by
beeps which become more frequent the
closer you come to the obstacle, until
they become a continuous beep when
the vehicle is approximately 25 centi -
metres from the obstacle.

Special features
Make sure that the ultrasonic sensors
are not obscured (by dirt, mud, snow,
etc.).
operating faults
When the system detects an operating
fault there will be a 5-second continu -
ous beep as a warning. Consult an ap-
proved dealer.
When the vehicle is being driven at
a speed below approximately 6 mph
(10 km/h), certain noises (motorcy -
cle, lorry, pneumatic drill, etc.) may
trigger the beeping sound.
Prolonged deactivation of the
system
You may permanently activate or deac-
tivate the front or rear parking distance
control separately.
From the vehicle settings personalisa -
tion menu (refer to the information on
the “Vehicle settings personalisation
menu” in Section 1), select the line
“front parking distance control” or “rear
parking distance control” then activate
or deactivate the system:
<: function deactivated;
=: function activated.
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.: de -
formation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
proved Dealer.
