2018 RENAULT MEGANE Owners Manual

2.9
Conditions for non-activation of the
system
Certain conditions will not enable the
system to be activated:
– five successive authorised standing start procedures - beyond five proce-
dures being performed, the function
will be prevented for approximately
10 minutes;
– high clutch temperature;
– excessive road gradient percentage;
– fault in the vehicle system (ESC, etc.).
Note: If the function is prevented by
any of these conditions, the message
“Launch Control ON” will not be dis-
played on the instrument panel.
Because of the accelera-
tion gained, this function
should only be used if traf-
fic conditions permit, and
in compliance with the local driving
regulations. Please ensure all the
conditions are met before each use.
Risk of accident or serious injury.
The use of the function accelerates
wear on the tyres; please refer to the
information on «Tyres» in Section 5
of your driver’s handbook.
STANDING START PROCEDURE (2/2)

2.10
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.).
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).
FUNCTION STOP AND START (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.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).
The ignition must be
switched off before leav-
ing the vehicle (please see
the information on “Starting,
stopping the engine” in Section 2).

2.11
Conditions for coming out of
engine standby
For automatic gearboxes:
– the brake pedal is released, posi-tion D or M engaged;
– or the brake pedal is released, po- sition N engaged and the parking
brake off;
– or the brake pedal is pressed again, with position P engaged or posi-
tion N engaged with the parking
brake applied;
– or position R is engaged;
– or the accelerator pedal is pressed;
– or in manual mode the gear lever is moved towards + or -.
For manual gearboxes:
– the gearbox is in neutral and the clutch pedal is slightly depressed, or
– the engine is in gear and the clutch pedal is pressed right down.
To fill up with fuel, the engine must
be stopped (and not on standby):
stop the engine (Please See
“Starting, stopping the engine” in
Section 2).
FUNCTION STOP AND START (2/4)
Preventing the engine from
standing by
In certain situations, such as negotiat-
ing a crossroads for instance, it is pos-
sible (with the system activated) to keep
the engine running so as to be ready to
move off quickly.
Automatic gearbox:
Keep the vehicle stationary without
pressing too hard on the brake pedal.
Manual gearbox:
Keep the clutch pedal pressed right
down.
Special note: depending on the vehi-
cle, if you switch off the ignition when
the engine is on standby, the warning
light
Ä is displayed for a few sec-
onds on the instrument panel.

open.

2.14
SPECIAL FEATURES OF PETROL VERSIONS
The following operating conditions:
– driving for long periods when the low fuel level warning light is lit;
– using leaded petrol;
– using fuel or lubrication additives which are not approved.
Or operating faults such as:
– faulty ignition system, running out of fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power,
as they may cause the catalytic con-
verter to overheat and thus reduce its
efficiency, or damage it irreparably
and cause heat damage to the vehi-
cle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved Dealer.
These faults may be avoided by regu-
larly taking your vehicle to an approved
Dealer at the intervals specified in the
Maintenance document.
Starting problems
To avoid damaging the catalytic con-
verter,
do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
starting fault.
If the fault cannot be identified, do not
keep trying to start the engine, but con-
tact an approved Dealer.
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 con-
tact with the hot exhaust system.

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 “Fuel
tank” in section 1 before restarting 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
Gear lever
Selecting reverse gear
Vehicle with manual gearbox: Follow
the grid marked on knob 1 and, depend-
ing on the vehicle, lift the ring against
the knob to engage reverse gear.
Vehicles with automatic gear-
box: refer to the information on the
“Automatic gearbox” in Section 2.
The reversing lights will come on as
soon as reverse gear is selected with
the ignition on.

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.
