2015 RENAULT GRAND SCENIC Light control

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.

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.

CRUISE CONTROL/SPEED LIMITER: speed limiter function (1/3)
The speed limiter function helps you
stay within the driving speed limit that
you choose, known as the limit speed.Controls
1 or 2 Main “On/Off” switch.
3 Speed limiter activation, memory
and increase (+).
4 Lowers the limited speed (-).
5 Speed limiter function standby (with limited speed memory) (O).
6 Activation and recall of memorised limited speed (R).
Switching on
Press switch 1 or 2 on the side .
Warning light
 comes on, lit orange,
and the message “Speed limiter” ap-
pears on the instrument panel A, ac-
companied by dashes to indicate that
the speed limiter function is activated
and waiting to store a limited speed.
To store the current speed, press
switch 3 (+): the limited speed replaces
the dashes and, depending on the vehi-
cle, the activation of the speed limiter is
confirmed by the message area being
lit orange. The minimum stored speed
is 20 mph (30 km/h).

CRUISE CONTROL/SPEED LIMITER: speed limiter function (2/3)
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 3 (+) to increase speed;
– switch 4 (-) to reduce speed.
The speed limiter function is
in no way linked to the brak-
ing system.
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).
The limited speed flashes on the instru-
ment panel and, depending on the ve-
hicle, the display area lights up in red to
inform you that the limit speed is being
exceeded.
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
limit speed: this speed flashes on the
instrument panel and, depending on
the vehicle, the display area will light up
in red.

CRUISE CONTROL/SPEED LIMITER: speed limiter function (3/3)
Putting the function on
standby
The speed limiter function is deacti-
vated when you press switch 5 (O). In
this case, the limited speed remains
stored and the message “Memorised”
accompanied by this speed appears on
the instrument panel A.
Depending on the vehicle, when the
function is on standby, this is confirmed
by the message area no longer being
lit orange.
Recalling the limit speed
If a speed has been stored, it can be re-
called by pressing switch 6 (R).
When the speed limiter is put on
standby, pressing switch 3 (+) re-
activates the function without taking
into account the stored speed: it is
the speed at which the vehicle is
moving that is taken into account.
Switching off the function
The speed limiter function is deacti-
vated if you press switch 1 or 2: in this
case a speed is no longer stored. The
orange warning light
 on the instru-
ment panel A goes out, confirming that
the function has stopped.

CRUISE CONTROL/SPEED LIMITER: cruise control function (2/4)
Switching on
Press switch 1 or 2,  side.
Warning light
 comes on, lit green,
and the message “Cruise ctrl” appears
on the instrument panel A, accom-
panied by dashes to indicate that the
cruise control function is activated and
waiting to store a cruising speed.
Activating cruise control
At a steady speed (above approx. 18
mph (30 km/h)), press switch 3 (+): the
function is activated and the current
speed is saved. The cruising speed re-
places the dashes and the activation of
the cruise control is confirmed, depend-
ing on the vehicle:
– by the appearance of the
 warn-
ing light;
– or by the message area lighting up in green.
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.
