warning RENAULT MEGANE SPORT TOURER 2015 X95 / 3.G Service Manual

2.20
If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
Operating principleEach 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 display 1 and on-
board computer 2 that the tyres are suf-
ficiently inflated and warns if they are
underinflated or leaking. The warning
light 4
 on the instrument panel
comes on to warn the driver if the pres-
sure is too low. 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.).
With the ignition on:
– Make short presses on the control
3
to select the tyre pressure display
(see “On-board computer: settings”
in Section 1);
– press and hold (around 3 seconds) the button 3 to launch the reset. A
flashing tyre followed by the mes-
sage “Pressure ref Ongoing” indi-
cates that the request to learn the
reference pressure has been taken
into account;
– reset can take several minutes of driving.

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 wheels over (how- ever this practice is not recom-
mended);
– after changing a wheel.
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.

Display
The warning light 4  on the in-
strument panel along with the display 1,
and messages on the display 2 indicate
any tyre pressure faults (flat tyre, punc-
tured tyre, system fault, etc.).
TYRE PRESSURE MONITORING SYSTEM (2/4)
1“Puncture”
The wheel A, together with the warn-
ing light 4
, indicates that the af-
fected wheel is punctured or severely
underinflated. Replace it or contact an
authorised dealer if it is punctured. Top
up the tyre pressure if the wheel is de-
flated.
This message appears along with the
® warning light.
“Adjust tyre pressure”
A coloured wheel A, together with the
warning light 4
, indicates a flat
tyre.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
While driving the warning light 4

goes off after a few minutes.

Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions allow.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.

TYRE PRESSURE MONITORING SYSTEM (3/4)
“CHECK TYRE PRESSURE
SENSORS”
The warning light
 flashes for
several seconds, then stays on, along
with the message “CHECK TYRE
PRESSURE SENSORS” and a missing
wheel B.
This message appears along with the
© warning light.
This message appears when at least
one wheel fitted on the vehicle does not
have sensors (e.g. emergency spare
wheel). In other cases, contact an au-
thorised dealer.
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, sensors, etc.).
Contact an authorised dealer to replace
the tyres and to find out about avail-
able accessories compatible with the
system: the use of any other accessory
could affect the correct operation of the
system or damage a sensor.
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.

Interchangeability of wheelsIf you wish to swap the wheels around,
please consult an approved dealer to
reinitialise the system.
Each of the sensors incor-
porated in the valves 5 is
dedicated to a single wheel:
under no circumstances
should you swap the wheels, with-
out resetting the system.
There is a risk of incorrect informa-
tion which could have serious con-
sequences.

DRIVER CORRECTION DEVICES AND AIDS (2/4)
Electronic stability control
ESC with understeer control
and traction control
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, indicator 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).
Traction control
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 traction
control system are deactivated. Consult
an authorised dealer.

2.26
The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the switch 1 again.
Note: the function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.
Emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
Operating principle
The system is for detecting an emer-
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig-
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
Operating faults
When the system detects an operat-
ing fault the message “Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma-
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you release it, the system may be trig-
gered;
– if you do not use the accelerator, the system will not be triggered.
DRIVER CORRECTION DEVICES AND AIDS (3/4)
Disabling the traction control
system
In some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit wheel-
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “Traction control off” is
displayed on the instrument panel to
inform you.

LANE DEPARTURE WARNING (1/2)
This function is a driving aid in the event of the accidental crossing o\
f
a continuous or broken line in the road. However, the function is not in-
tended to replace the driver. The function can be disrupted under certain
conditions, including:
– poor visibility (rain, snow, fog, dirty windscreen, glare of the sun, partially ob- scured road lines, etc.);
– roads with tight bends;
– closely following a vehicle in the same lane;
– worn road markings, difficult to distinguish or spaced very widely apart;
– narrow roads;
– ...
In this case, warning light
 on the instrument panel goes out to indicate that
the function will not operate (lines not detected).
Under no circumstances should this function replace the driver’s care or respon-
sibility whilst performing manoeuvres.
This system notifies the driver when
they accidentally cross a continuous or
broken line.
This function uses a camera attached
to the windscreen, behind the rear-view
mirror.

2.29
LANE DEPARTURE WARNING (2/2)Adjustment
From the vehicle settings customisation
menu (please refer to the information
on the “Vehicle settings customisation
menu” in Section 1), you can:

Driving
When a limited speed has been stored
and this speed is not reached, driving is
similar to driving a vehicle without the
speed limiter function.
Once you have reached the stored
speed, no effort on the accelera-
tor pedal will allow you to exceed
the programmed speed except in an
emergency (refer to information on
“Exceeding the limit speed”).
Varying the limit speed
The limit speed may be changed by re-
peatedly pressing:
– switch 2 (+) to increase the speed;
– switch 3 (-) to decrease the speed.
Exceeding the limit speed
It is possible to exceed the limit speed
at any moment. To do this: press the
accelerator pedal firmly and fully
(beyond the kickdown point).
While driving over the speed limit, the
speed limit flashes on the instrument
panel, the display area A goes red
and, depending on the vehicle, a beep
sounds.
Then, as far as is possible, release
the accelerator pedal: the speed lim-
iter function will return as soon as you
reach a speed lower than the stored
speed.
Limited speed cannot be maintained
If driving up or down a steep gradient,
the system is unable to maintain the
limited speed: the stored speed flashes
on the instrument panel, the area A
goes red, and depending on the vehi-
cle, a warning beep sounds.
The speed limiter function is
in no way linked to the brak-
ing system.

CRUISE CONTROL/SPEED LIMITER: cruise control function (2/4)
Switching on
Press switch 1 on the side showing .
Warning light 7 comes on, lit green, and
the message “Cruise control” appears
on the instrument panel and dashes
appear in zone 6 to indicate that the
cruise control function is activated and
waiting to store a cruising speed.
Activating cruise control
At a steady speed (above 20 mph
(30 km/h) approximately) press
switch 2 (+): the speed is stored. The
cruising speed will appear in zone 6.
Cruise control activation is confirmed
when area A lights up green in addition
to indicator light 7. Area B also lights
up green to indicate that the cruising
speed has been reached.
Driving
Once a cruising speed is stored and
the cruise control function is active,
you may lift your foot off the accelera-
tor pedal.
Important: you are never-
theless advised to keep
your feet close to the pedals
in order to react if neces-
sary.
