8Eco-driving
Eco-driving
Eco-driving refers to a range of everyday practices
that allow the motorist to optimise the vehicle's
energy consumption (fuel and/or electricity) and
CO
2 emissions.
Optimise your use of the gearbox
With an automatic gearbox, favour automatic
mode. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift indicator prompts you to engage
the most suitable gear. Whenever this indication
is displayed on the instrument panel, follow it
straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These practices
help to save on energy consumption, reduce CO
2
emissions and decrease general traffic noise.
Favour the use of the "Eco" driving mode by
selecting it using the "DRIVE MODE" control.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of electrical equipment
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning. At speeds above 31 mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep the
temperature in the passenger compartment down
(e.g. sunroof blind, window blinds).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting
functions, if they are not managed automatically.
Switch off the heated seat as soon as possible.
Adapt your use of the headlamps and/or foglamps
to the level of visibility, in accordance with
current legislation in the country in which you are
driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The vehicle
will warm up much faster while driving.
As a passenger, avoid connecting your multimedia
devices (e.g. film, music, video game) to help
reduce the consumption of energy.
Disconnect all portable devices before leaving the
vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle. Place the
heaviest items in the boot as close as possible to
the rear seats.
Limit the loads carried in the vehicle and minimise
wind resistance (e.g. roof bars, roof rack, bicycle
carrier, trailer). Preferably, use a roof box.
Remove roof bars and roof racks after use.At the end of winter, remove snow tyres and refit
summer tyres.
Comply with the servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the driver's side.
Carry out this check in particular:
–

before a long journe
y.
–

a
t each change of season.
–

a
fter a long period out of use.
Do not forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g. engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, your vehicle will emit pollution. Visit a
dealer or a qualified workshop as soon as possible
to restore your vehicle's nitrogen oxide emissions
to legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.
You will only see the fuel consumption of your new
vehicle settle down to a consistent average after
the first 1,900 miles (3,000 kilometres).
Optimising the driving range (rechargeable
hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.

Stop as soon as it is safe to do so and switch off
the ignition.
Contact a dealer or a qualified workshop.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact
Have it checked by a dealer or a qualified
workshop.
Emergency braking assistance
(EBA)
This system reduces the emergency stopping
distance, by optimising the braking pressure.
It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this is
a reduction in the resistance of the pedal and an
increase in braking efficiency.
Anti-slip regulation (ASR) /
Dynamic stability control (DSC)
Anti-slip regulation (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
These systems are activated in the event
of a problem with grip or trajectory
(confirmed by this warning lamp flashing on the
instrument panel).
E-TENSE 4X4 360
The dynamic stability control is optimised
to be able to react later on this vehicle.
Deactivation/Reactivation
In exceptional conditions (e.g. moving a vehicle
that is bogged down in mud, stuck in snow, on
loose soil), it may prove useful to deactivate the
DSC/ASR systems, so that the wheels can move
freely and regain grip.
Reactivate the system as soon as the level of grip
permits.
The ASR system is deactivated/
reactivated in the ADAS touch screen
application.
Deactivation/reactivation of the ASR
system is indicated by this indicator lamp
on the instrument panel coming on/going out and
the display of a message.
The ASR system is automatically reactivated
every time the ignition is switched off or at
speeds over 31 mph (50 km/h)
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a malfunction, this warning
lamp lights up 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.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage the
driver to take extra risks or drive at high speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels (tyres
and rims), braking and electronic components,
as well as the assembly and repair procedures
provided by dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.

81
Safety05
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings, refer to the
corresponding section.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC) must
not have any faults.
The vehicle speed must be between 37 and 99
mph (60 and 160 km/h).
If the system detects that the trailer is
snaking, it applies the brakes to stabilise
the trailer and reduces engine power, if necessary,
to slow the vehicle (indicated by the flashing of
this warning lamp on the instrument panel and
the brake lamps coming on).
For information on weights and towed loads, refer
to the Engine technical data and towed loads
section or your vehicle’s registration certificate.
To ensure safe driving with a Towing device, refer
to the corresponding section.
Malfunction
If a fault occurs, this warning lamp lights
up on the instrument panel, accompanied
by a message and an audible signal.
To continue towing a trailer, reduce speed and
drive carefully!
Have it checked by a dealer or a qualified
workshop.
The trailer stability control system
provides an extra safety feature under
normal driving conditions, when following the
recommendations for use of trailers and
current legislation in force in your country. It
must not encourage the driver to take extra
risks, such as using a trailer in unsuitable
conditions of operation (e.g. excessive load,
exceeded nose weight, worn or under-inflated
tyres, faulty braking system) or driving at
excessive speed.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
When driving on slippery or poor surfaces, the
system may not be able to prevent sudden
trailer snaking.
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiting system
This system reduces the pressure of the seat belt
on the chest of the occupant, thus improving their
protection.
In the event of an impact
Depending on the nature and seriousness
of the impacts, the pyrotechnic device may
trigger before and independently of airbag
deployment. Deployment of the pretensioners
is accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt system
checked, and if necessary replaced, by a dealer
or a qualified workshop.

► Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
Tyres
►  Check the tyre pressures of the towing vehicle
and of the trailer, observing the recommended
pressures.
Lighting
►  Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine towing device is used, the
rear parking sensors will be deactivated
automatically to avoid the audible signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►  Reduce speed and lower the engine speed to
limit the amount of heating produced.
►  Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/switching off the
engine
The electronic key must be present in the
passenger compartment.
If the electronic key is not detected, a message
is displayed.

Driving06
– The outside temperature must be between 0°C
and 35°C.
Putting the engine into standby (STOP
mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop:
–

With an automatic gearbo
x, at speeds below
12 mph (20 km/h) on BlueHDi versions, or below
2 mph (3 km/h) on PureTech 130, 180 and 225
versions, when you depress the brake pedal or
place the gear selector in mode N.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if the
conditions for operation are not met and in the
following cases:
–

St
eep slope (ascending or descending).
–

Needed t
o maintain a comfortable temperature
in the passenger compartment.
–

Demisting activ
e.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode is
not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:
–

With the select
or in mode D or M: with the
brake pedal released.
–

With the select
or in mode N and the brake
pedal released: with the selector at D or M.
–

With the select
or in mode P and the brake pedal
depressed: with the selector at R, N, D or M.
–

With re
verse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following cases:
–
V
ehicle speed exceeds 2.5 mph (4 km/h) with
PureTech 130, 180 and 225 versions, or 16 mph
(25 km/h) with BlueHDi versions.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a dealer or a qualified
workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►  Switch off the ignition then start the engine
again with the "START/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a dealer or
a qualified workshop.
Tyre under-inflation
detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving, not
when stationary.
It compares the information given by the wheel
speed sensors with reference values, which must
be reinitialised every time the tyre pressures are
adjusted or a wheel changed.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.

111
Driving06
The tyre under-inflation detection cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high speed,
long journey):
–

w

orsens road-holding.
–

lengthens braking dist
ances.
–

c

auses premature wear of the tyres.
–

increase
s energy consumption.
The inflation pressures defined for the
vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly when
the tyres are "cold" (vehicle stopped for 1 hour
or after a journey of less than 6 miles (10 km)
at moderate speeds).
Otherwise, add 0.3 bar to the pressures shown
on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination
of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►  Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
►  Stop the vehicle as soon as it is safe to do so.
The loss of pressure detected may not
always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►  Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►  If it is not possible to carry out this check
immediately, drive carefully at reduced speed.
►  In the event of a puncture, use the temporary
puncture repair kit or the spare wheel (depending
on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre blow-
out. This is because analysis of the values read
by the wheel's speed sensors can take several
minutes.
The alert may be delayed at speeds below 25
mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is
reinitialised.
Reinitialisation
►  The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system
can be reinitialised in the Settings>Vehicle
touch screen application.
►  Then select Safety > Tire Pressure Setup.
►  Press YES to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.

112
Driving06
Malfunction
In the event of a malfunction, these
warning lamps light up on the
instrument panel.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a dealer or a qualified
workshop.
Non-standard or 'space-saver' spare
wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel has
been replaced by one of uniform size (the same
as the others), the pressure readjusted and
the reinitialisation carried out.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.
These systems do not make it possible to
exceed the laws of physics.
Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected by
the accumulation of dirt (e.g. mud, ice), in poor
weather conditions (e.g. heavy rain, snow), or
if the bumpers are damaged.
If the front bumper is to be repainted, contact
a dealer or a qualified workshop; certain types
of paint could interfere with the operation of
the radar(s).


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or masked
by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a dealer or a qualified workshop
to recalibrate the camera; otherwise, the
operation of the associated driving aids may
be disrupted.
Other cameras
The images from the camera(s) displayed
on the touch screen or on the instrument panel
may be distorted by the terrain.
