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!
If 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.
Manual air conditioning
The manual air conditioning system operates
with the engine running.

Safety
► Press the central part of the steering wheel.
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 ABS warning lamp, 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
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.
They come into operation in the event of a grip
or trajectory problem.
This warning lamp on the instrument panel flashes to indicate that they are
operating.
Deactivation/Reactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
these systems, so that the wheels can turn freely
and regain grip.

Safety
5With GTi version

► Press this button to deactivate DSC
and ASR.
Except GT
i version
► Select " Traction control " from the
"Driving functions " menu on the touch
screen to deactivate ASR.
Deactivation is confirmed when this
indicator lamp is displayed on the
instrument panel accompanied by a message
and, depending on version, the lighting of the
indicator lamp in the button.
Reactivate the system(s) when normal grip is
restored.
This/these system(s) is/are reactivated
automatically each time the ignition is switched
off or above 31 mph (50
km/h) (except GTi
version).
Below 31 mph (50
km/h), reactivate them
manually.
With GTi version
► Press this button again to reactivate
DSC and ASR.
Except GTi version
► Select Traction control from the
Driving functions menu on the touch
screen to reactivate ASR.
Malfunction
In the event of a malfunction of these
systems, this warning lamp comes on,
accompanied by the display of a message and
an 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 swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
At speeds between 37 and 99 mph (60 and
160
km/h), if the system detects oscillating trailer
movements (snaking), it applies the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow the vehicle.
This warning lamp flashes on the instrument panel and the brake lamps
light up to draw attention to this corrective action.
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 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.

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 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 engine or gearbox, as well as to the electrical
systems of your 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).

Driving
Starting with the key
The parking brake must be applied.
► With a manual gearbox in neutral, fully
depress the clutch pedal.
► With an automatic gearbox in mode P or N,
fully depress the brake pedal.
► Insert the key into the ignition switch.
– The system recognises the starting code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In some cases, you may have to apply
some force to turn the wheels (if the
wheels are turned against a kerb, for
example).
► With a petrol engine, operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. As soon as the engine starts, release the
key.
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
► Wait until this warning lamp goes off in
the instrument panel, then turn the key to
position 3 without pressing the accelerator pedal,
to operate the starter motor until the engine
starts. As soon as the engine starts, release the
key.
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.
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 key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes after
the ignition is switched off, and prevents the
engine being started by anyone who does not
have the key.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message in the screen.In
this case, your vehicle will not start; contact a
PEUGEOT dealer as soon as possible.
