Section 6 RENAULT MEGANE 2017 4.G Service Manual

2.10
For manual gearboxes:
– the gearbox is in neutral;
– and the clutch pedal is released. If the warning light
 flashes, this
means that the clutch pedal is not
sufficiently released;
– and the vehicle speed is less than approximately 1.86 mph (3 km/h).
STOP AND START FUNCTION (1/4)
This system enables a reduced fuel
consumption and lower greenhouse
gas emissions.
The system is activated automati-
cally when the vehicle is started. While
driving, the system stops the engine
(standby) when the vehicle is at a
standstill (traffic jam, traffic lights, etc).
Conditions for engine
standby
The vehicle has set off from where it
was parked;
For automatic gearboxes:
– the gearbox is in position D, M or N;
– and the brake pedal is pressed (suf-ficiently hard);
– and the accelerator pedal is not pressed;
– and the speed is zero for around 1 second.
The engine remains on standby if posi-
tion P is selected, or if position N is se-
lected with the handbrake engaged and
the brake pedal released.
If the engine is put in
standby, the electronic
parking brake (depending
on the vehicle) is not ap-
plied automatically.
Engine on standby - braking
assistance is no longer op-
erational.
If the engine stalls while the system
is in operation, pressing the clutch
pedal right down will start it again.
Keep your vehicle station-
ary when the engine is
on standby (shown by the
warning light
 on the
instrument panel).
Before getting out of the
vehicle, you must switch
off the ignition (please see
section on “Starting, stop-
ping the engine”).
Engine on standby - power-
assisted steering is no
longer operational.
For all vehicles:
The warning light
 on the instru-
ment panel is lit when the engine is on
standby. The vehicle equipment re-
mains operational while the engine is
stopped.
Depending on the vehicle, when the
engine switches to standby, the steer-
ing assistance may no longer be opera-
tional.
In this case it becomes operational
again when the engine is no longer on
standby or the speed exceeds approxi-
mately 0.62 mph (1 km/h) (downhill,
slope, etc.).

2.12
STOP AND START FUNCTION (3/4)
Conditions preventing the
standby of the engine
Certain conditions prevent the system
from using the engine standby function,

RENAULT card:
– the driver’s door is not closed;
– the driver’s seatbelt is not fastened.
for all vehicles:
– reverse gear is engaged;
– the bonnet is not locked;
– the outdoor temperature is too low or too high (less than around 0 °C or
higher than around 30 °C);
– the battery is not sufficiently charged;
– the difference between the vehicle interior temperature and the auto-
matic climate control instruction is
too high;
– parking distance control is in opera- tion; – for vehicles with automatic gear-
boxes, the gradient is steeper than
approximately 12%;
– the “Clear View” function is activated (please see “Automatic Climate
Control” in Section 3);
– the engine temperature is too low;
– the emission control system is being regenerated;
– the Sport mode of the Multi-Sense is activated (depending on the vehicle);
– ...
Warning light
 is displayed on the
instrument panel. This notifies you that
engine standby is not available.
Deactivate the Stop and
Start function when per-
forming any operations in
the engine compartment.
Special case for vehicles with
a RENAULT card
With the engine on standby (traffic jam,
traffic lights, etc.), if the driver unfas-
tens the seat belt and opens the driv-
er’s door, or gets out of the seat, the
ignition is switched off.
The assisted parking brake is applied
automatically.
To restart and reactivate the Stop and
Start system, start the engine (please
refer to “Starting, stopping the engine”
in Section 2).
Special case of vehicles with
a key
With the engine on standby (traffic
jam, traffic lights, etc.), if you get out of
the vehicle, a beep warns you that the
engine is on standby and has not been
stopped.

2.13
STOP AND START FUNCTION (4/4)
Special feature of the automatic
engine re-start
Under certain conditions, the engine
can restart on its own in order to guar-
antee your safety and comfort.
This can occur especially when:
– the outdoor temperature is too low or too high (less than around 0 °C or
higher than around 30 °C);
– the “Clear View” function is activated (please see “Automatic Climate
Control” in Section 3);
– the battery is not sufficiently charged;
– the vehicle speed is above 3 mph (5 km/h) (downhill slope, etc.);

tion. The message “Stop & Start deac-
tivated” will appear on the instrument
panel and the integrated warning light 2
on the switch will light up.
Pressing again will reactivate the
system. The message “Stop & Start ac-
tivated” will appear on the instrument
panel and the integrated warning light 2
on switch 1 will go out.
Note: With the engine on standby,
press switch 1 to automatically re-
start the engine.
The system is automatically reacti-
vated each time the vehicle is started
(see “Starting, stopping the engine” in
Section 2).
Operating faults
When the message “Check Stop &
Start” appears on the instrument panel
and the integrated warning light 2 lights
up on the switch 1, the system is deac-
tivated.
Please consult an authorised dealer.
Before getting out of the
vehicle, you must switch
off the ignition (please see
section on “Starting, stop-
ping the engine”).Special feature of vehicles with
a key: for some of these condi-
tions the automatic restarting of the
engine is inhibited if a front door is
open.

2.15
SPECIAL FEATURES OF DIESEL VERSIONS
Diesel engine speed
Diesel engines are fitted with an injec-
tion pump which prevents the engine
speed being exceeded irrespective of
the gear selected.
If the message “Check antipollution
system” is displayed along with warn-
ing lights
Ä and ©, consult an
authorised dealer immediately.
When driving, depending on the fuel
grade used, it is possible that white
smoke may be emitted.
This is due to the exhaust particle filter
being cleaned automatically, and does
not affect the way the vehicle runs.
Running out of fuel
If the tank has been completely
drained, the system must be reprimed
after the tank is refilled: see information
on the “fuel tank” in section 1 before re-
starting the engine.
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.
Precautions to be taken in
winter
To avoid any faults in icy weather:
– ensure that the battery is always fully charged,
– always keep the diesel tank rela- tively full to avoid water vapour con-
densing in it and accumulating at the
bottom of the tank.

2.16

When stationary, and de-
pending on the slope and/or
vehicle load, it may be nec-
essary to pull up the hand-
brake at least two extra notches and
engage a gear (1
st or reverse gear)
for vehicles with a manual gearbox
or position P for vehicles with an au-
tomatic gearbox.
An impact to the under-
side of the vehicle while
manoeuvring (e.g.: strik-
ing a post, raised kerb or
other street furniture) may result in
damage to the vehicle (e.g.: defor-
mation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap-
proved Dealer.
Make sure that the hand-
brake is properly released
when driving (red indicator
light off), otherwise over-
heating, or even damage, may
occur.
To apply:
Pull lever 3 upwards. Check that the
vehicle is immobilised. The warning
light
} on the instrument panel will
come on.

2.17
ELECTRONIC PARKING BRAKE (1/3)
Note:
To indicate that the electronic parking
brake is released, a beep sounds and
the message “Apply parking brake” ap-
pears on the instrument panel:
– with the engine running: when the driver’s door is opened;
– with the engine switched off (eg. when the engine stalls): when a front
door is opened.
In this case, pull and release switch 2 to
apply the assisted parking brake.
Assisted release of the parking
brake
The brake will be released as soon as
the vehicle starts and accelerates.
Assisted operation
The electronic parking brake immobi-
lises the vehicle when the engine is
switched off by pressing the engine
start/stop button 1 or by turning the
ignition key (key in the “ ON" 2 po-
sition).
In all other circumstances, for example
stalling of the engine or placing of
the engine on standby by the Stop
and Start function (refer to the informa-
tion on the "Stop and Start" function in
Section 2), the electronic parking brake
is not applied automatically. Manual
mode must be used. For certain country-specific model ver-
sions, the assisted brake application
function is not activated. Refer to the
information on “Manual operation”.
To confirm that the electronic parking
brake is applied, the message “Parking
brake on” and warning light
}
on the instrument panel and warning
light 3 on the switch 2 light up.
After the engine is switched off, indi-
cator light 3 goes out several minutes
after the electronic parking brake has
been applied and indicator light
}
goes out when the vehicle is locked.
Before leaving the vehi-
cle, check that the assisted
parking brake is fully ap-
plied. Warning light 3 on
switch 2 and warning light
}
on the instrument panel light up to
show that the parking brake is ap-
plied but go out when the doors are
locked.

DRIVING ADVICE, ECO-DRIVING (3/5)
ECO mode
ECO mode is a function which opti-
mises fuel consumption. It acts upon
certain power consuming systems in
the vehicle (heating, air conditioning,
power-assisted steering, etc.) and on
certain driving actions (acceleration,
gear changing, cruise control, decele-
ration, etc.).
Limiting acceleration enables low fuel
consumption in urban and surrounding
areas. Reduced usage of the air condi-
tioning reduces fuel consumption with-
out affecting heating comfort.
Free wheel in ECO mode
Depending on the vehicle, for vehi-
cles fitted with an automatic gearbox,
switching to “free wheel” is favoured to
slow down the vehicle without using the
engine brake. By releasing the acceler-
ator pedal completely to anticipate de-
celeration, you will save fuel.Activating the function
The function can be activated:
– by pressing switch
6.
– by pressing the switch 7 (please refer
to the information on “Multi-Sense” in
Section 3);
– from the navigation menu on the multimedia screen (please refer to
the multimedia instructions).
The warning light
 comes on on
the instrument panel to confirm activa-
tion.
While driving, it is possible to leave the
ECO mode temporarily in order to im-
prove engine performance.
For this, depress the accelerator pedal
firmly and fully.
ECO mode is reactivated when you
take pressure off the accelerator pedal.
Disabling the function
Press switch 6.
The warning light
 goes out on
the instrument panel to confirm deac-
tivation.
The distance covered in “free wheel”
mode is displayed, depending on the
vehicle, on the multifunction screen 4
or the instrument panel 5.
To activate/deactivate the “free wheel”
mode, see “Vehicle settings customisa-
tion menu” in Section 1.

DRIVING ADVICE, ECO-DRIVING (5/5)
Advice on use
– Favour the 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 conditio-
ning, it is normal to observe an in-
crease 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.

2.29
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.
However, the function is
not intended to replace the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver. Check the tyre pressures, in-
cluding the emergency spare wheel,
once a month.

2.39
DRIVER CORRECTION DEVICES AND AIDS (10/10)
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.
AB
® 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.
