2015 RENAULT GRAND SCENIC Owners Manual

2.21
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 on-board compu-
ter 1 that the tyres are sufficiently in-
flated and warns if they are underinfla-
ted or leaking. The warning light

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 con-
trol 2 to select the tyre pressure
display (please refer to “On-board
Computer” in Section 1);
– press and hold (around three sec- onds) the control 2 to launch initial-
isation. Flashing tyres followed by
the message “Pressure ref ongoing”
means that the request to learn the
reference pressures has been taken
into account;
– reset can take several minutes of dri- ving.
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 vi-
gilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
TYRE PRESSURE MONITORING SYSTEM (1/4)
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.

TYRE PRESSURE MONITORING SYSTEM (2/4)
« Adjust tyre pressure »
A wheel A shown in orange on the dis-
play 4 together with the warning light
 indicates a flat tyre.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
While driving the warning light 3

goes off after a few minutes.
DisplayThe display 4 and the warning light 3
 on the instrument panel warns
you of any inflation faults (flat tyre,
puncture, system fault, etc.).

A
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.For your safety, the warning light ® requires you to stop immedia-
tely as soon as traffic conditions allow.
« Puncture »
The affected wheel A appears red on
the display 4 along with the warning
light 3
 and a beep. They indicate
that the affected 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 deflated. This message
appears along with the
® warn-
ing light.
« Check tyre pressure sensors »
The affected wheel A is shown in white
on the display 4 together with the
flashing warning light 3
 and the
warning light
©. This message ap-
pears when at least one wheel fitted on
the vehicle does not have a sensor (e.g.
emergency spare wheel). Otherwise,
consult an authorised dealer.

2.23
Readjustment of tyre
pressures
The tyre pressures must be adjusted
when cold (please refer to the label lo-
cated on the edge of the driver’s door).
If the tyre pressures cannot be checked
when they are cold, the recommended
pressures should be increased by 0.2
to 0.3 bar (3 PSI).
Never deflate a hot tyre.
Tyre repair product and
inflation kit
Because the valves are specially desi-
gned, only use equipment approved by
the approved network.
TYRE PRESSURE MONITORING SYSTEM (3/4)
Interchangeability of wheels
If you want to swap the wheels round,
consult an authorised dealer to reinitia-
lise 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.

Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, hubcaps, etc.).
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. When it is fitted to the vehicle,
the message “Check tyre pressure sen-
sors” is displayed on the instrument
panel.
Changing a wheel
The system may take several minutes depending on use for the new
wheel positions and pressures to be recognised; check the tyre pres-
sures after all operations.

DRIVER CORRECTION DEVICES AND AIDS (1/5)
Depending on the vehicle, this is com-
posed of:
– anti-lock braking system (ABS);
– emergency brake assist;
– electronic stability program (ESC) with understeer control;
– traction control;
– grip control;
– hill start assistance. Operating faults:
–
© and x lit up on the in-
strument panel alongside mes-
sages “Check ABS”, “Check brak-
ing system” and “Check ESC”: ABS,
ESC and emergency brake assist
are deactivated. Braking is always
enabled;
–
x, D, © and ® lit
up on the instrument panel alongside
the message “Braking system fault”:
this indicates a fault in the braking
system.
In both cases, consult an approved
Dealer.
Anti-lock braking system
(ABS)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi-
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par-
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
However, the functions do not take
the place of the driver. They do
not increase the vehicle’s limits
and should not encourage you
to drive more quickly. Therefore,
they can under no circumstances
replace the vigilance or responsibil-
ity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).
Your braking systems
are partially operational.
However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu-
late the force applied in the braking
system.

2.26
DRIVER CORRECTION DEVICES AND AIDS (2/5)
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.
Electronic stability program
(ESC) with understeer 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).

2.27
DRIVER CORRECTION DEVICES AND AIDS (3/5)
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
© and  appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.
Disabling the traction control
system
If the vehicle is fitted with this function,
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. 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.

DRIVER CORRECTION DEVICES AND AIDS (4/5)
Grip control
If fitted on the vehicle, grip control
makes it easier to control the vehicle on
low grip surfaces (soft ground, etc.).
Tyres
When they need to be re-
placed, only tyres of the
same make, size, type and
profile should be used.
Tyres fitted to the vehicle should
either be identical to those fitted
originally or conform to those
recommended by your approved
dealer.

“Soft ground” mode
Turn the button 2: the integrated warn-
ing light
\b comes on, along with
the instrument panel message “Non
grip road mode on”.
This position enables optimal usage on
soft ground (mud, sand, dead leaves,
etc.). “Soft ground” mode uses traction
control functions. The system automa-
tically switches to “Road” mode after
around 25 mph (40 km/h), and the inte-
grated warning light
on button 2
comes on.
“Expert” mode
Turn the button 2: the integrated warn-
ing light

comes on, along with
the instrument panel message “Expert
mode on”.
In this position, engine speed is left
under the driver’s control. The system
automatically switches to “Road” mode
after around 25 mph (40 km/h), and
the integrated warning light
on
button 2 comes on.
“Road” mode
When the vehicle is started up, the
warning light
on button 2 comes
on, along with the instrument panel
message “Standard road mode on”.
This position enables optimal usage
under normal driving conditions (dry-
ness, humidity, light snow, etc.).
“Road” mode uses traction control func-
tions.
