Safety
Deactivating the front
passenger airbag


Passenger airbag OFF
To ensure the safety of the child, the front passenger airbag MUST be deactivated
when a "rearward facing" child seat is
installed on the front passenger seat.
Otherwise, the child risks being seriously
injured or killed in the event of deployment of
the

airbag.
Vehicles not equipped with a
deactivation/reactivation control
Installing a "rearward
facing" child seat on
the front passenger seat is strictly prohibited
- risk of death or serious injury in the event of
airbag deployment!
Deactivating/Reactivating the front
passenger airbag
For vehicles on which it is fitted, the switch is
located on the side of the dashboard.


With the ignition off:
► T o deactivate the airbag, turn the key in the
switch to the "OFF " position.
►

T
o reactivate it, turn the key to the "ON"
position.
When the ignition is switched on:
This warning lamp comes on and remains lit to signal deactivation.
Or
This warning lamp comes on for about 1 minute to signal activation.

The seats shown below are fitted with ISOFIX
compliant mountings:


*Depending on version.
The mountings comprise three rings for each
seat, indicated by a marking:
–

T
wo rings A, located between the vehicle seat
backrest and cushion.


The 2 latches on ISOFIX child seats are
secured to them.
–

One ring
B, located behind the seat, called the
TOP TETHER, for attaching seats fitted with an
upper strap.

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.

In some circumstances, a message indicates
that it is necessary to turn the steering wheel
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 you r 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.
Pay particular attention to pedestrians and
cyclists who may not hear the vehicle coming
despite the pedestrian horn.

(EAT8), the steering column does not lock, but
the gearbox locks in mode P.
If the vehicle is not immobilised, the
engine will not stop.

103
Driving
6Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g. driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking.
If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.
►

In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions
on the electric parking brake control until the
vehicle comes to a complete stop.

Driving
Active Suspension Control
This system adapts the vehicle suspension
according to the road condition and profile, the
vehicle load, the driving style and the selected
driving mode.
The system uses a computer and sensors, which
determine the optimal level of shock absorption
to be applied to each shock absorber.
The operation of the system depends on
the driving mode selected
(depending on
equipment).
For more information on the Driving modes,
please refer to the corresponding section.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
Driving modes
The driving modes available depend on the engine and equipment of the vehicle.
Driving modes are selected using the following
control:




► Press the control to display the modes on the
instrument panel.
►

Press the control again to change mode.
When the message disappears, the selected
mode is activated and remains indicated on the
instrument panel (except Normal

driving mode is selected by default.
Eco
To reduce energy consumption by reducing the
performance of the heating and air conditioning,
without deactivating them.
Comfort
To achieve more comfortable driving and softer
suspension.
Normal
To restore the default settings.
Together with Active Suspension Control, this
mode offers the best compromise between
comfort and handling.
Sport
To obtain more dynamic driving with action on
the power steering, Active Suspension Control,
accelerator and gear changes (with an automatic
gearbox) and the possibility of displaying the
vehicle’s dynamic settings on the instrument
panel.

(EAT8), refer to the corresponding section.
Coasting mode
Depending on version or engine, with an
EAT8 gearbox and the gear selector in mode
D, except in
Sport mode, gradually and fully
releasing the accelerator pedal allows free-
wheeling which can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).

108
Driving
Combines Hybrid mode and Comfort mode of
the Active Suspension Control function.
To favour flexible shock absorption improving
driving comfort on poor surfaces.
For more information on Active
Suspension Control , refer to the
corresponding section.
4WD (4-wheel drive)
(Depending on version)
Improves the vehicle's grip at low and moderate
speeds by driving all 4 wheels continuously.
4WD mode (4-wheel drive) is especially
suited to driving on snow-covered roads and
difficult terrain (e.g.
mud, sand) as well as ford
crossings, at moderate speed.
Depending on the driving conditions and the
battery charge level, 4WD mode may be 100%
electric.
If the system does not detect a situation of wheel
slipping or poor grip after 300 metres of driving, it
switches to Hybrid mode.
This mode will be even more effective if the vehicle is fitted with suitable tyres,
such as winter tyres.
The grip can be improved up to 84 mph
(135

km/h) using the electric motors; above this
speed, the vehicle is driven by the front wheels
only.
Hill start assist
This system keeps the vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
The system is only active when:
–

The vehicle is completely stationary
, with your
foot on the brake pedal.
–

Certain slope conditions are met.
–


The driver
’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. Then check that the parking
brake indicator lamp and the P indicator lamp
in the electric parking brake control are on
fixed.
The hill start assist function cannot be deactivated. However, using the parking
brake to immobilise the vehicle interrupts its
operation.

Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►

Switch off the ignition then start the engine
again with the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
PEUGEOT
dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.

111
Driving
6It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.
The tyre under-inflation detection cannot, in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1

hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►

If it is not possible to carry out this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25

mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system
can be reinitialised in the
Settings>Vehicle touch screen application.
►

Then select
Safety > Tire Pressure Setup.

11 2
Driving
► Press YES to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
Non-standard or 'space-saver' spare
wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel
has been replaced by one of uniform size (the
same as the others), the pressure readjusted
and the reinitialisation carried out.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.
These systems do not make it possible to
exceed the laws of physics.
Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected
by the accumulation of dirt (e.g.
mud, ice),
in poor weather conditions (e.g.
heavy rain,
snow), or if the bumpers are damaged.
If the front bumper is to be repainted, contact
a PEUGEOT dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar(s).


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (e.g.
inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(e.g.
headlamps of an oncoming vehicle, low
sun, reflections on a damp road, leaving a
tunnel, alternating shade and light) can also
impair detection performance.
