Safety05
accompanied by a message and an audible signal,
indicates an EBFD malfunction.
You must stop the vehicle.
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.

82
Safety05
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting system.
Height adjustment

► To adjust the height of the anchorage point,
squeeze control A and slide it to the notch desired.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
For the centre seat, the buckle is held horizontally
by an elastic strap if the centre seat belt is not
being used.

increasing audible signal for approximately two
minutes. After two minutes, these warning lamps
remain on as long as the front seatbelts are not
fastened.
Not fastened at the rear
When the ignition is switched on, with the
engine running or the vehicle moving at a speed
below 12 mph (20 km/h), the warning lamp and
the corresponding indicator lamps light up for
1 minute, if one or more rear seat belts are not
fastened.

Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►  Monitor your environment and keep your
hands on the wheel to be able to react to anything
that may happen any time.
►  Drive smoothly, anticipate the need for braking
and maintain a longer safety distance, especially
in bad weather.
►  Stop the vehicle before performing operations
that require sustained attention (e.g. settings).
►  During long trips, take a break every 2 hours.
Important!
Never leave the engine running in a closed
space without sufficient ventilation.
Internal combustion engines emit toxic
exhaust gases such as carbon monoxide.
Danger of poisoning and death!
In very severe wintry conditions
(temperature below -23°C), let the engine
run for 4 minutes before moving off, to ensure
the correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied. Risk of overheating and
damaging the braking system!
Never park the vehicle and never leave the
engine running on a flammable surface
(e.g. dry grass, dead leaves).The vehicle
exhaust system is very hot, even several
minutes after the engine stops. Risk of fire!
Never drive on surfaces covered with
vegetation (e.g. tall grass, accumulated
dead leaves, crops, debris) such as a field, a
country lane overgrown with bushes or a
grassy verge.
This vegetation could come into contact with
the vehicle's exhaust system or other systems
which are very hot. Risk of fire!
Make sure you do not leave any item in the
passenger compartment which could act
like a magnifying glass under the effect of the
sun's rays and cause a fire. Risk of fire or
damage to interior surfaces!
Never leave the vehicle unattended, with
the engine running. If you have to leave
your vehicle with the engine running, apply the
parking brake and put the automatic gearbox
into position N or P.
Never leave children inside the vehicle
unsupervised.
E-TENSE 4X4 360
Repeated hard braking in this vehicle
can generate loud banging noises which are
completely normal.
Continue driving but with lighter braking so
that the braking system can cool down.
The performance of the braking system
remains unaffected.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
internal combustion engine or electric motor, the
gearbox and the electrical systems of the vehicle.


If the vehicle absolutely must drive through a
flooded section of road:
►  Check that the depth of the water does not
exceed 15 cm, taking account of waves that might
be generated by other users.
►  Deactivate the Stop & Start function.
►  For rechargeable hybrid engines, place the
mode selector in 4WD position (depending on
version).
►  Drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h).

97Driving06
► 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.

while pressing the "START/STOP" button to assist
unlocking of the steering column.
Petrol engines
With Petrol engines, after a cold start,
pre-heating the catalytic converter can cause
noticeable engine vibrations, for anything up
to 2 minutes (accelerated idle speed).
Starting rechargeable hybrid
vehicles
►  Fully depress the brake pedal and press the
START/STOP button for approximately 2 seconds.
►  Keep your foot on the pedal until this
indicator lamp comes on, indicating the
activation of the rechargeable hybrid system
(confirmed by an audible signal).
To exit Park mode, wait for the READY
indicator lamp to come on.
By default, the system starts in Electric mode.
Depending on certain parameters (battery
charge level or outside temperature), the system
determines whether it is necessary to start the
petrol engine.
It is possible to change the driving mode at any
time using the mode selector.
When the vehicle starts in electric mode,
it makes no noise.
