4Activation/Deactivation
► Place the ring of the lighting control stalk in
the “AUTO” position.
It is configured in the Settings > Vehicle
touch screen application.
Operation
"Road" mode

This lighting provides a higher light beam, an
increased intensity of the headlamps and a
decreased intensity of the modules.
The range of this lighting is approximately
240
m.
This mode is activated once the vehicle has
been moving for more than 2
seconds at a speed
between 0 and 68
mph (0 and 110 km/h).
"Motorway" mode

The headlamps and modules create a cone of
light with a high beam, suitable for fast roads.
The range of this lighting is approximately
280 m.
This mode is activated if the vehicle has been
moving for more than 5 seconds above 68 mph
(110 km/h) and is deactivated if the vehicle has
been moving for more than 5 seconds below 56
mph (90 km/h).
"Fog" mode

This mode is activated if the vehicle is moving at
a speed between 0 and 43 mph (70 km/h) and
the rear foglamps are on.
The range of this lighting is approximately
180 m.
Beyond 43 mph (70 km/h), the function switches
to "road" or "motorway" mode even if the rear
foglamps are activated.
Night Vision
This system identifies and signals the presence
of pedestrians and animals in the driver's field
of vision, in low exterior light conditions, using
an infrared camera located at the front of the
vehicle.
Select the "Night vision " display mode if you
want the infrared camera image to be displayed
constantly on the instrument panel. When the
conditions are met, an alert is triggered if there is
a risk of collision.
The permanent
display disappears upon
switching off the ignition or if the conditions are
not met.
This system is a driving aid system that cannot, under any circumstances,
replace the driver's assessment of night-time
visibility and traffic conditions.
In some cases, the differences in temperature
are insufficient and the system may not detect
all dangers or, conversely, it may give false
warnings (e.g. engines of lorries parked by
the side of the road).

not available (in " Night Vision"mode), the
indicator lamp comes on in grey.
If all operating conditions are met, the
indicator lamp comes on in green: the
display on the instrument panel (with " Night
Vision " mode selected) and the triggering of
alerts are available.
If certain operating conditions (speed or
temperature) are not met, the indicator
lamp comes on in orange: only the display on the
instrument panel is available (in " Night Vision"
mode).
Whilst the exterior light is too bright or the dipped
beam headlamps have not been switched on,
the alerts are not available.




The camera detection range is between 15 m
(for pedestrians) and 200 m, depending on
visibility conditions.
The image provided by the camera is displayed
in shades of grey in the instrument panel; warm
objects appear brighter than cold objects.
If pedestrians or animals are detected, they
appear in yellow frames.
If the system detects a risk of
collision with pedestrians or
animals, it triggers an alert: one of these symbols
appears on the instrument panel. The
corresponding silhouette is framed in red. If the "
Night Vision" display mode has not been
selected, the alert is triggered in the form of a
temporary window.
In the event of an alert, the driver may act by
making an avoiding manoeuvre or by braking.

Safety
5Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
–

Anti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
–


T
railer stability assist (TSA).
Anti-lock braking system (ABS)/Electronic brake force
distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
Electronic brake force distribution (EBFD)
manages overall braking pressure on each
individual wheel.
►

When braking in an emergency
, depress
the pedal very firmly and maintain this
pressure.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
The fixed illumination of this warning lamp signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
This warning lamp, when lit together with the STOP and ABS warning lamps,
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 PEUGEOT 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 PEUGEOT 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).
PSE (PEUGEOT Sport Engineered)
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.

82
Safety
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 PEUGEOT 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 PEUGEOT
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.
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 more 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 PEUGEOT 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.

Driving
6Driving 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.
PSE (PEUGEOT Sport Engineered)
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).

98
Driving
► Drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h).
►

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 PEUGEOT 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 PEUGEOT 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 PEUGEOT dealer.
