Driving06
If the driver takes no action after the vehicle
has been stopped, the electric parking brake is
applied automatically after about 5 minutes.
Cruise control remains active after
changing gear, regardless of the gearbox
type.
When the driver attempts to reactivate
cruise control after the function has been
paused, the message "Activation not possible,
unsuitable conditions" is displayed briefly if
reactivation is not possible (safety conditions
not met).
Changing the programmed speed setting with
the Road signs recognition function
►  Press 5-MEM to accept the speed suggested
by the system on the instrument panel, then press

Messages and alerts
The digital instrument panel's "Driving" display
mode must have been selected first.
The actual order in which these messages
or alerts are displayed may vary.
"Cruise paused" or "Cruise control on hold"
following brief acceleration by the driver.
"Active cruise control", no vehicle
detected.
"Cruise paused", vehicle detected.
"Active cruise control", vehicle detected.
(orange)
"Take back control".
►  Brake or accelerate, depending on the context.
(red)
"Take back control".
►  Take back control of the vehicle immediately:
the system cannot manage the current driving
situation.
"Activation refused, conditions
unsuitable".
The system refuses to activate cruise control, as
the necessary conditions are not fulfilled.

125
Driving06
The system status is saved when the
ignition is switched off.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbol is
displayed in green: by small steering actions, the
system directs the vehicle and keeps it in the
position chosen by the driver, in the traffic lane.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
The driver can change the position of the vehicle
at any time, by turning the steering wheel. When
the driver feels that the vehicle’s position is
appropriate, whilst keeping hands on the steering
wheel, they must release the pressure to let the
system resume control of the steering, but the
vehicle will not be automatically centred within
the lane.
Pausing/Suspending the
system
The driver must act promptly if they
believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
intervention on the brake pedal that causes
the Adaptive cruise control to pause will also
cause the system to pause.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding the
steering wheel, the function must be
reactivated by pressing the button again.
Automatic pause
– Triggering o f the ESC.
– Prolonged failure t o detect one of the lane
limit markings. In this case, the Lane keeping
assist function can take over, and the system will
reactivate itself once the operating conditions are
met again.
In response to action by the driver: suspension
– Activation of the direction indicators.
– Tra velling outside the lane limits.
–

T
oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brak
e pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–

Pausing o
f Adaptive cruise control.
–

Deactiv
ation of the ASR.

Driving06
– Driving on a rolling road.
Malfunction
In the event of a malfunction, the
Service warning lamp comes on and
this (orange) symbol appears on the instrument
panel, accompanied by the display of a message
and an audible signal.
Have it checked by a dealer or a qualified
workshop.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.


This system:
– w arns the driver that their vehicle is at risk of
collision with the preceding vehicle, a pedestrian
or a cyclist.
–

reduc
es the vehicle's speed to avoid a collision
or to limit its severity.
The speed will be reduced by a maximum
of 16 mph (25 km/h) (versions with camera
only) or by a maximum of 31 mph (50 km/h)
(versions with camera and radar).
The system also takes motorcyclists into
account.
It may also react on animals. Animals
(especially animals smaller than 0.5 m)
and objects on the road are not necessarily
detected.
This system includes three functions:
–

Collision Risk Alert.
–


In

telligent emergency braking assistance
(iEBA).
–

Activ
e Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not replace the need for
driver vigilance.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system detects a potential
collision, it prepares the braking circuit.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and limits
Vehicle moving forward without trailer.
Brake system operational.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the
instrument panel without any additional
message, to indicate that the automatic braking
system is not available.

129
Driving06
This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the system
via the driving aids touch screen application is
recommended, for instance:
–

T
owing a trailer (particularly a trailer without
its own braking system).
–

Carrying long objects on roo
f bars.
–

D
riving with snow chains.
–

U
sing an automatic car wash.
–

Performing an
y maintenance (e.g. changing a
wheel, working inside the engine compartment).
–

Placing the v
ehicle on a rolling bench in a
workshop.
–

T
owing the vehicle.
–

Follo
wing an impact to the windscreen close to
the detection camera.
The system is automatically deactivated
once the use of a different diameter
"space-saver" type spare wheel is detected, or
if a fault with the two lateral brake lamps is
detected.
The system diagnoses permanently its
capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions
(e.g. sensor initialization, board voltage out of
regular range, activation of stability system).
Therefore, the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle
(keep within the GVW limit and load
height limits for roof bars).
Following an impact (e.g.  a collision), the
system is automatically deactivated.
Have it checked by a dealer or a qualified
workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►  Select one of the 3 preset
thresholds: "Far ", "Medium" or "Near".
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own vehicle
and the object identified for the collision risk, and
the operation of the vehicle (e.g. actions on the
pedals, steering wheel) to trigger the alert at the
most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake!" is displayed.
Level 3: a micro-braking may be given, confirming
the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically at
lower speed.

130
Driving06
It is possible that collision warnings are
not given, are given too late or seem
unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time to
avoid an accident.
If you select "Far" in the touch screen,
then the system warns sooner. This
increases the safety but increases also the
amount of alerts, if the legal safety distance is
not kept.
To reduce the alert occurrence, you can change
the setting to either of the other two.
Intelligent emergency braking
assistance (iEBA)
This function increases vehicle deceleration if the
driver does not brake enough to avoid a collision.
This assistance is only provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called "automatic emergency
braking", intervenes after the acoustic alert if the
driver does not operate the brake pedal quickly
enough.
The system aims at reducing the speed of impact
or avoiding a collision if the driver fails to react.
The speed will be reduced by a maximum
of 16 mph (25 km/h) (versions with
camera only) or by a maximum of 31 mph
(50 km/h) (versions with camera and radar).
Operation
The system operates subject to the following
conditions:
– At reduced speed in an urban environment,
when a stationary vehicle, pedestrian or cyclist is
detected.
–

The v
ehicle's speed is between 6 mph and
53 mph (10 km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle is
detected.
This warning lamp flashes (for
approximately 10 seconds) as soon as the
function applies the vehicle’s brakes.
During the flashing time, the function is not
available.
In the event of automatic emergency braking,
keep the brake pedal depressed, also after a
complete stop is reached, to prevent the vehicle
from rolling away.
The driver can override the automatic
emergency braking at any time by firmly
turning the steering wheel and/or firmly
depressing the accelerator pedal.
The brake pedal may feel hard and vibrate
slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.

135
Driving06
Operating limits
The system goes into standby automatically in
the following cases:
–

ESC deactiv
ated or operation triggered.
–

Speed belo

Blind spot monitoring
For more information, refer to the General
recommendations on the use of driving
and manoeuvring aids.


This system warns the driver of a potential
danger posed by the presence of another vehicle
(car, lorry, motorcycle) in the vehicle's blind
spots (areas hidden from the driver's field of
vision) using sensors located on the sides of the
bumpers.


A warning lamp appears in the door mirror on the
side in question:

Installation tips
►  To fit the snow chains during a journey, stop
the vehicle on a flat surface at the side of the
road.
►  Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
►  Fit the snow chains following the instructions
provided by the manufacturer.
►  Move off gently and drive for a few moments,
without exceeding 31 mph (50 km/h).
►  Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that you
practise fitting the snow chains on a level
and dry surface before setting off.
Avoid driving with snow chains on roads
that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Rechargeable hybrid vehicles
The use of snow chains is only authorised
on the front wheels.
The driving mode selector must be on the 4WD
position (depending on version).
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine and for a maximum
cumulative period of around 30 minutes, you can
continue to use functions such as the audio and
telematics system, dipped beam headlamps or
courtesy lamps.
Selecting the mode
A confirmation message is displayed when
energy economy mode is entered, and the active
functions are placed on standby.
If a telephone call is in progress at the
time, it will be maintained for around 10
minutes via the audio system’s hands-free
system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions immediately,
start the engine and let it run:
–

For le
ss than 10 minutes, to use the equipment
for approximately 5 minutes.
–

For more than 10 minut
es, to use the equipment
for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the 12 V battery, refer
to the corresponding section.
Load reduction mode
This system manages the use of certain functions
according to the level of charge remaining in the
battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as the air conditioning
and the heated rear screen.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Bonnet
Stop & Start
Before doing anything under the bonnet,
you must switch off the ignition to avoid any
risk of the engine restarting automatically.
Take care with objects or clothing that could
be caught in the blades of the cooling fan

Diesel fuel system
This system is under very high pressure.
All work must be carried out only by a dealer or
a qualified workshop.
Checking levels
Check all of the following levels regularly in
accordance with the Manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a dealer or a
qualified workshop.
The fluids must comply with the
Manufacturer's requirements and with
the vehicle's engine.
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a dealer or a qualified
workshop.
Engine oil
The level is checked, with the engine
having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped with
an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended that
you check the level, and top up if necessary, every
3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.

162
Practical information07
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and pull
it out completely.
►  Wipe the end of the dipstick using a clean, lint-
free cloth.


►  Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil level:
the correct level is between marks A (max) and
B (min).
Do not start the engine if the level is:
–

abo
ve mark A: contact a dealer or a qualified
workshop.
–

belo
w mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for your engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your dealer or qualified
workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►  Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►  Wait a few minutes before checking the level
again using the dipstick.
►  Top up the level if necessary.
►  After checking the level, carefully screw the
oil filler cap back on and replace the dipstick in
its tube.
The oil level indication displayed on the
instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the
"MAX" mark. If not, check the brake pads
for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with the
engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the "MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
