Ease of use and comfort
Repositioning the backrests
First check that the outer seat belts are
lying vertically flat alongside the backrest
latching rings.


► Put the backrest 3 in the upright position and
push it firmly to latch it home.
►

Check that the red indicator is no longer
visible in the release grip 1

.
►

Ensure that the outer seat belts were not
trapped during the operation.
Please note: an incorrectly latched
backrest compromises the safety of
passengers in the event of sudden braking or
an accident.
The contents of the boot may be thrown
forward - risk of serious injury!
Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
Depending on version, the controls are
accessible in the " Air conditioning" touch
screen menu or are grouped together in the
control panel on the centre console.
Air distribution

1. Windscreen demisting/defrosting vents
2. Front side window demisting/defrosting vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5.Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable air vents
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►


Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in perfect working order

.
►

If the system does not produce cold air
,
switch it off and contact a PEUGEOT dealer
or a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!

Ease of use and comfort
3If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop & Start,
refer to the corresponding section.
ECO driving mode
Selection of this mode optimises fuel
consumption, but limits the performance
of the heating and air conditioning, without
however deactivating them.
Dual-zone automatic air
conditioning
This system automatically controls the activation
of the air conditioning system, regulating the
temperature, air flow and air distribution inside
the passenger compartment.
The air conditioning system operates with
the engine running, but the ventilation and its
controls can be accessed with the ignition on.

Maintenance
recommendations
The infrared camera has a wash nozzle
connected to the vehicle’s front screenwash
system.
This nozzle operates every 5th use of the
screenwash.
Regularly check that the camera is clean.
In bad weather, or in wintry conditions, ensure
that the camera is not covered with mud, ice or
snow.
Malfunction
An orange warning lamp coming on whilst all the operating conditions have been
met, accompanied by a message, indicates a
system malfunction.
Contact a PEUGEOT dealer or a qualified
workshop.
Wiper control stalk
In wintry conditions, remove snow, ice or
frost present on the windscreen, around
the wiper arms and blades and on the
windscreen seal, before operating the wipers.
The permanent display disappears upon
switching off the ignition or if the conditions are
not met.
Night Vision is a driving aid system that
cannot, under any circumstances,
replace the personal assessment of
night-time visibility and traffic conditions.
In some conditions, the contrasts 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 on the edge of the road).

alerts are available.
If certain operating conditions (speed or
temperature) are not met, the
indicator
lamp comes on in orange: only the
display in 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.
When pedestrians or animals are detected, they
appear in yellow frames.
When the system detects a risk of
collision with pedestrians or
animals, it triggers an alert: one of these symbols
is displayed in 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.

Electronic 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) and 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.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the
event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a PEUGEOT dealer or a qualified
workshop as soon as possible.
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 as soon as it is safe to do so.
Contact a PEUGEOT dealer or a qualified
workshop.
The normal operation of the ABS may result in slight vibrations in the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems checked by a PEUGEOT dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by 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 optimises traction using
engine braking and by applying the brakes on
the driving wheels to avoid wheel spinning. It
also enhances the vehicle's directional stability
while accelerating.
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

Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this
warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a PEUGEOT dealer or a qualified
workshop to have the systems checked.
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 used by PEUGEOT
dealers.
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
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.
Between 37 and 99 mph (60 and 160
km/h), if
the system detects oscillations (snaking) in the
movement of the trailer, it acts on the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow down the vehicle.
This warning lamp flashes in the instrument panel and the brake lamps
light up to draw attention to this corrective action.
For information on towed loads and masses,
refer to the Technical data section or your
vehicle’s registration certificate
To ensure complete safety while driving with
a Towing device , refer to the corresponding
section.
Malfunction
If a fault occurs, this warning lamp comes
on in the instrument panel, accompanied
by a message and an audible signal.
If you wish to continue towing a trailer, reduce
your speed and drive carefully!
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
The trailer stability assist system offers enhanced safety in normal driving,
provided that the recommendations on towing
a trailer are observed. It should not
encourage the driver to take risks, such as
towing a trailer in adverse operating
conditions (overloading, failure to observe the

Driving
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 to carry out operations that
require close attention (such as adjustments).
►


During long trips, take a break every two
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 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
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
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 you are obliged to drive on a flooded road:
► Check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users.
►

Deactivate the Stop & Start function.
►


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.

limit heating up.
In all cases, pay 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
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, with a code that must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
