2018 RENAULT MEGANE Braking system

CRUISE CONTROL (1/4)
The cruise control function helps you to
maintain your driving speed at a speed
that you choose, called the cruising
speed.
This cruising speed may be set at any
speed above 20 mph (30 km/h).
The cruise control function
is in no way linked to the
braking system.
This function is an addi-
tional driving aid. This func-
tion does not take the place
of the driver. Therefore, it
can under no circumstances replace
the driver’s responsibility to respect
speed limits and to be vigilant (the
driver must always be ready to
brake). Cruise control must not be
used in heavy traffic, on winding or
slippery roads (black ice, aquaplan-
ing, gravel) and during bad weather
(fog, rain, side winds etc.).
There is a risk of accidents.
Controls
1 Main “On/Off” switch.
2 Controls for:
a cruising speed activation, storage
and increase (+) ;
b decreasing cruising speed (-).
3 Activation with recall of saved cruis- ing speed (R).
5 Switch the function to standby (with cruising speed saved) (O).

CRUISE CONTROL (3/4)
Exceeding the cruising speed
The cruising speed may be exceeded
at any time by depressing the accelera-
tor pedal. While it is being exceeded,
the cruising speed flashes on the in-
strument panel.
Then, release the accelerator: after a
few seconds, the vehicle will automati-
cally return to its set cruising speed.
Cruising speed cannot be
maintained
When driving down a steep gradient,
the system is unable to maintain the
cruising speed: the stored speed will
flash on the instrument panel informa-
tion display to inform you of this situ-
ation.
Adjusting the cruising speed
The cruising speed can be changed by
pressing the switch 2 repeatedly:
– side a (+) to increase the speed;
– side b (-) to reduce the speed.
The cruise control function
is in no way linked to the
braking system.

ADAPTIVE CRUISE CONTROL (6/7)
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.
The driver should always adapt their speed to the traffic conditions, re-
gardless of the system indications.
The system should under no circumstances be taken to be an obstacle dete\
ctor
or an anti-collision system.
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.
System disturbance
In a complex environment (metal bridge, etc.), the system may be affected.
Risk of inadvertent braking.
Operating faults
When the system detects an operating
fault, the
\b warning light lights up
on the instrument panel, with the mes-
sage “Check cruise control”.
There are two possibilities:
– the system is temporarily disrupted (for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out.
– Otherwise, this may be caused by another fault. Consult an approved
dealer

2.67
ADAPTIVE CRUISE CONTROL (7/7)
Limitation of the system operation
– 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 or\
der to ensure the proper operation of the
system.
– Fixed obstacles (stationary vehicles, traffic jams, toll booths etc.) or objects travelling at low speed or of a \
small size ( motor-
bikes, bicycles, pedestrians etc.) may not be detected by the system.
– A vehicle entering the same lane will only be detected once it has entere\
d the detection zone. Sudden or late braking may then take place.
– When entering a bend or curve, the sensor may temporarily no longer dete\
ct the vehicle in front, and this may lead to acce- leration.
– When exiting a curve, the detection of the vehicle in front may be affected or delayed. Sudden or late braking may then take place.
– A slower vehicle travelling in an adjacent lane may be detected and cause\
a slowing down if one of the two vehicles is trav- elling too close to the lane of the other.
– The system is deactivated below around 20 mph (40 km/h). Drivers must \
react accordingly.
– Sudden changes in situation are not instantly taken into account by the \
system. Drivers must remain vigilant at all times and
under all circumstances.
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);
– traffic is heavy;
– the vehicle is travelling in a tunnel;
– the vehicle is travelling on a windy road;
– the vehicle is travelling on a slippery road or in poor weather conditio\
ns (fog, snow, rain, side winds etc.).
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.

AUTOMATIC TRANSMISSION (2/3)
Driving in manual modeWith the selector lever in position D,
move the lever to the left into the M po-
sition. Shifting the lever or the paddles
repeatedly allows you to change gears
manually:
– to move down through the gears, push the lever forwards or press the
left-hand paddle;
– to move up through the gears, push the lever backwards or press the
right-hand paddle.
The gear selected is displayed on the
instrument panel.
Special casesIn certain driving conditions (for exam-
ple, engine protection, operation of the
Electronic Stability Programme: the au-
tomatic system may change gear auto-
matically. Likewise, to prevent incorrect
manoeuvres, a gear change may be re-
fused by the automatic system: in this
case the gear display flashes for a few
seconds as a warning.
Special circumstances
– If the bends and road surface do
not allow you to stay in automatic
mode (e.g. in the mountains), we
recommend that you change to
manual mode. This will prevent the
automatic gearbox from changing
gear repeatedly when climbing, and
permit engine braking on long de-
scents.
Driving in automatic mode
Put lever 1 into position D.
In most road conditions you will en-
counter, you will not need to touch your
lever again: the gears will change au-
tomatically at the right time and at the
most suitable engine speed because
the automatic system takes into ac-
count the vehicle load and road contour
and adjusts itself to the particular driv-
ing style you have chosen.
Economical driving
When driving, always leave the lever
in position D, keeping the accelerator
pedal lightly depressed to ensure auto-
matic gear changes at a lower engine
speed.
Accelerating and overtaking
Depress the accelerator pedal firmly
and fully (so that it goes beyond the
kickdown point).
This will enable you to change down
to the optimum gear within the
engine range.
When facing uphill, to remain
stopped, do not keep your foot on
the accelerator.
Risk of overheating the automatic
gearbox.

When turning corners,
accelerating or braking,
ensure that the recepta-
cle being held by the cup
holder is not dislodged.
There is a risk of burning if hot liquid
escapes.
Ensure that no hard, heavy
or pointed objects are
placed in the “open” stor-
age compartments in such
a way that they may fall onto pas-
sengers during sudden turning or
braking.

OPERATING FAULTS (4/7)
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to correct pres-
sures, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved Dealer.
White smoke from the exhaust. In the diesel version, this is necessar-
ily a fault. Smoke may be caused by
particle filter regeneration. Refer to the information on “Special fea-
tures of diesel versions” in Section 2.
Smoke under the bonnet. Short-circuit or cooling system leak. Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil level (refer to the in-
formation on “Engine oil level: topping up,
filling” in Section 4).
