Seat belt not fastened/
unfastened alerts




1. Front left seat belt warning lamp
2. Front right seat belt warning lamp
3. Rear left seat belt warning lamp
4. Rear centre seat belt warning lamp
5. Rear right seat belt warning lamp
If the corresponding seat belt is not fastened
or is unfastened, when the ignition is switched
on, the seat belts warning lamp comes on in the
instrument panel and the corresponding warning
lamp (1 to 5) comes on in red in the seat belt and
front passenger airbag warning lamps display.
If a rear seat belt is not fastened, the
corresponding warning lamp ( 3 to 5)
comes on for around 1 minute.
Above about 12 mph (20 km/h) and for 2
minutes, each warning lamp corresponding to
an occupied seat whose seat belt is unfastened
flashes, accompanied by an audible signal. After
these 2 minutes, the corresponding seat warning
lamp remains on until the driver or the front/rear
passenger fasten their seat belt.
Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they
will not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g.
a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
At the front, adjusting the position of the
seat belt may require the seat height to be
adjusted.
In order to be effective, a seat belt must:
–

be tightened as close to the body as
possible.
– be pulled in front of you with a smooth
movement, checking that it is not twisted.
–

must only be used to secure one person.
–


not show signs of tearing or fraying.
–


not be changed or modified, in order to
avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shorter than 1.5
metres.
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all work on your vehicle's
seat belts, contact a qualified workshop with
the skills and equipment needed, which a
PEUGEOT dealer is able to provide.
Have the seat belts checked regularly by a
PEUGEOT dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by PEUGEOT
dealers.

Safety
5Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
PEUGEOT dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof, as these help to secure the curtain
airbags.
Active bonnet

The active bonnet has been designed to
optimise the safety of pedestrians in the event of
collision with the front of the vehicle.
The pyrotechnic system is triggered at the
hinges of the bonnet to lift it, when the sensors
located at the front of the vehicle detect a
collision.
Deployment of the active bonnet is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system. The airbag
warning lamp comes on.
After triggering, do not try to open or close
the bonnet. Call a towing company or go to
the nearest PEUGEOT dealer or qualified
workshop, driving at a speed below 19 mph
(30
km/h).
Make sure that you adjust the height of the
driver's seat - risk of hindrance to visibility!
This equipment will only trigger once. If a second impact occurs (during the same
or a subsequent accident), the active bonnet
will not trigger.
After an accident or if the vehicle has been
stolen, have the system checked.
Do not tamper with the pyrotechnic systems
under the bonnet, close to the struts - risk of
explosion!
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
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. You must contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.
The active bonnet may not deploy in the event of
an impact.

The red control is located on the edge of each
rear door (marked by a label).
Activation/Deactivation

► To activate the child lock, turn the built-in key
in the red control as far as possible:
•

T
o the right on the left-hand rear door.
•

T
o the left on the right-hand rear door.
►

T
o deactivate the child lock, turn the key in
the opposite direction.
Do not confuse the child lock control,
which is red, with the back-up locking

Electric child lock
(Depending on version)
This control prevents the opening of the rear
doors using their interior handles and the use of
the rear electric windows.
Activation/Deactivation

► With the ignition on, press this button to
activate/deactivate the child lock.
When the indicator lamp is on, the child lock is
activated.
With the child lock activated, it is still
possible to open the doors from outside

This system is independent and in no circumstances does it take the place of
the central locking control.
Check the status of the child lock each time
you switch on the ignition.
Always keep the electronic key with you when
leaving the vehicle, even for a short time.
In the event of a serious impact, the electric
child lock is switched off automatically to
permit the exit of the rear passengers.

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.

Driving
Operating conditions and
limits
Vehicle moving forward without trailer.
Brake system operational.
ASR system activated.
Seat belts fastened for all passengers.
Stabilised speed on roads with no or low
curvature.
This warning lamp lights up on the instrument panel without any additional
message, to indicate that the automatic braking
system is not available.
This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the system
via the driving aids touch screen application is
recommended, for instance:
–

T

owing a trailer (particularly a trailer without its
own braking system).
–

Carrying long objects on roof bars.
–


Driving with snow chains.
–


Using an automatic car wash.
–


Performing any maintenance (e.g.
changing a
wheel, working inside the engine compartment).
–

Placing the vehicle on a rolling bench in a
workshop.
–


T

owing the vehicle.
–

Following a damage of the windscreen close
to the detection camera.
The system is automatically deactivated when the use of certain types of
"space-saver" spare wheel (smaller diameter)
is detected, or if a fault with the brake pedal
switch or at least two brake lamps is detected.
Following a severe crash (e.g.
with airbag
deployment), the system is automatically
deactivated.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
In case the detection is degraded or
temporarily unavailable by environment
conditions, then a driver indication is not
displayed (because a driver action is not
requested).
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle (keep within the GVW limit and load
height limits for roof bars).
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
► In the ADAS touch screen application,
select Functions>Automatic Braking
System .
►

Select one of the 3 preset
thresholds:

"Far", "Medium" or "Near".
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the
collision risk, and the operation of the vehicle
(e.g.
actions on the pedals, steering wheel) to
trigger the alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given,
confirming the risk of collision (optional).
