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!

recently selected profile remains on.
Changing the profile setting does not reactivate
AUTO mode if it was deactivated.
In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, in order to
limit the delivery of cold air into the passenger
compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer than
the comfort setting requested, there is no
need to alter the value displayed to more
quickly reach the required level of comfort.
The system automatically corrects the
temperature difference as quickly as possible.
"Air Quality System" (AQS)
function
Using a pollution sensor, this function
automatically activates recirculation of the
interior air once a certain level of polluting
substances in the exterior air is detected.
When the air quality returns to a satisfactory
level, recirculation of interior air is automatically
deactivated.
This function is not designed to detect
unpleasant odours.
Recirculation is automatically activated when the
windscreen wash is used or when reverse gear
is engaged.

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.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior

increase with engine speed.
►

Reduce speed and lower the engine speed to
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
display of a message, the engine will not start.
Contact a PEUGEOT dealer.
Starting/Switching off the
engine
The electronic key must be present in the passenger compartment.
If it is not detected, a message is displayed.
Move the electronic key so that the engine
can be started or switched off.
If there is still a problem, refer to the "Key
not detected - Back-up starting or Back-up
switch-off" section.

Driving
6Operation

On an ascending slope, with the vehicle
stationary, the vehicle is held for a short time
when you release the brake pedal:
–
provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a short time when you
release the brake pedal.
Malfunction
These warning lamps come on in the event of a malfunction.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
Active Suspension Control
This suspension adapts itself to the following
parameters: state and profile of the road, load
of the vehicle, driving style and selected driving
mode.
It is managed by a computer, which interprets
the data transmitted by different sensors to
apply the optimal level of damping to each shock
absorber.
It offers three modes: Comfort, Normal and
Sport.
The mode can be selected using the DRIVE
MODE control on the central console.
For more information on the Driving modes,
please refer to the corresponding section.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using the following
control:




Pressing the control displays the modes on the
instrument panel.
When the message disappears, the selected
mode is activated and remains indicated on the
instrument panel (except NORMAL mode).
With petrol / Diesel engines
Whenever the ignition is switched on, NORMAL
mode is selected by default.
ECO
This mode reduces fuel consumption, but
restricts the performance of the heating and
air conditioning systems, without however
deactivating them.
Free-wheeling in ECO mode: depending on
version, with the EAT8 gearbox, moving into
"free-wheeling" is encouraged to slow the vehicle
down without using engine braking. You can
save fuel by anticipating the need to slow down
and lifting your foot fully off the accelerator pedal.
