Advice
An incorrectly installed child seat in a vehicle compromises the child's safety in
the event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
child seat harness keeping the slack relative
to the child's body to a minimum, even for
short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly to the seat of your
vehicle. If your passenger seat is adjustable,
move it forwards if necessary.
The head restraint must be removed
before installing a child seat with a
backrest on a passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Children at the rear
At rear seating positions, always leave
sufficient space between the front seat and:
–

a "rearward facing" child seat,
– the child's feet for a child seat fitted
"forward facing".
T
o do this, move the front seat forwards and,
if necessary, straighten its backrest.
For optimal installation of the "forward facing"
child seat, verify that its backrest is as close
as possible to the backrest of the vehicle
seat, if possible in contact with it.
Children at the front
The legislation on carrying children on
the front passenger seat is specific to each
country. Refer to the legislation in force in the
country in which you are driving.
Deactivate the front passenger airbag when a
"rearward facing" child seat is installed on the
front passenger seat.
Otherwise, the child would risk being
seriously injured or killed if the airbag were
deployed.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
We recommend using a booster seat with
backrest, equipped with a belt guide at
shoulder level.

102
Driving
On detecting speed limit information, the system
displays the value.


For a suggested maximum speed, the first time
that the vehicle exceeds it by more than 3 mph
(5 km/h) (e.g. 59 mph (95 km/h)), the speed is
displayed and flashes for 10 seconds (depending
on version).
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
– Poor weather (rain, snow).
– Atmospheric pollution.
– Towing.
– Driving with a space-saver type spare wheel
or snow chains fitted.
– Tyre repaired using the temporary puncture
repair kit.
– Young drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
– Road signs that are obstructed, non-standard,
damaged or bent.
– Obsolete or incorrect maps.
► ensure that the mat is secured correctly ,
► never fit one mat on top of another .
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a PEUGEOT dealer
or a qualified workshop.
Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.
– Speed limit details from the navigation system
mapping.
You should update your navigation mapping regularly in order to receive
accurate speed limit information from the
system.
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in.
The automatic reading of road signs is a driving aid system and does not always
display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit in the
instrument panel is updated as you pass
a speed limit sign intended for cars (light
vehicles).
Activation / Deactivation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.
Information displayed on
the instrument panel


1. Detected speed limit indication
or
2. End of speed limit indication


The system is active but is not detecting speed
limit information.

Driving
6Certain situations cannot be managed by the
system and require the driver to take back
control of the vehicle.
Cases of non-detection by the radar:
–
Pedestrians, some cyclists, animals.
–


Stationary vehicles (traffic jam, breakdown,
etc.).


– Vehicles crossing your lane.
– V ehicles driving in the opposite direction.
Situations in which the driver must pause the
cruise control system:


– Vehicles in a tight bend.
– When approaching a roundabout.

– When following a narrow vehicle.
Reactivate cruise control when conditions permit.
Situations in which the driver is prompted to
immediately resume control:
–

Excessively sharp deceleration by the vehicle
in front of you.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
The system must not be activated in the
following situations:
–

Use of the "space-saver" type spare wheel
(depending on version).
–

Towing.
–

Following an impact on the front bumper
.
Be particularly careful:
– When motorcycles are present and
when there are vehicles staggered across the
traffic lane.
–

When you enter a tunnel or cross a bridge.
Cruise control operates by day and night,
in fog or moderate rainfall.
However, it is strongly recommended that
you always keep a safe distance from the
vehicles in front of you according to the traffic
conditions, weather conditions and the state
of the road surface.
Use the cruise control only where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Do not activate the cruise control in urban
areas where pedestrians are likely to cross
the road, in heavy traffic (except for versions
with EAT8 gearbox), on winding or steep
roads, on slippery or flooded roads, when
there is snowfall, if the front bumper is
damaged or when the brake lamps have
failed.
In certain circumstances, it may not
be possible for the speed setting to be
maintained or even reached: loaded vehicle,
ascending a steep hill, etc.
The system is not intended for the following situations:
–

if the front end of the vehicle has been
modified (addition of long-range headlamps,
painting of the front bumper),
–


driving on a racing circuit,
–


running on a rolling road,
–


use of snow chains, non-slip covers or
studded tyres.
The use of mats not approved by PEUGEOT


may interfere with the operation of the cruise
control.
To avoid any risk of jamming the pedals:
–

ensure that the mat is secured correctly
,
–

never put one mat on top of another
.

Practical information
Load reduction mode
This system manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as the air conditioning and the
heated rear screen.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Fitting roof bars
Fitting directly to the roof
To install the roof bars, you must secure them
only to the four fixing points on the roof frame.
These points are concealed by the vehicle's
doors when they are closed.


Use accessories approved by PEUGEOT
and follow the manufacturer's
recommendations and fitting instructions so
as to avoid the risk of damaging the bodywork
(deformation, scratches, etc.).
Do not exceed the maximum authorised
load, shown in the instructions for the
roof bars.
If the height exceeds 40
cm, adapt the speed
of the vehicle to the profile of the road, to
avoid damaging the roof bars and the fixings
on the roof.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects that are longer than the vehicle.
Fitting on longitudinal bars

The transverse bars must be fixed at the
engraved markings on the longitudinal bars.
As a safety measure and to avoid damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
Observe the instructions on fitting and use
contained in the guide supplied with the roof
bars.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one side.
Arrange the heaviest part of the load as close
as possible to the roof.
Secure the load firmly.
Drive gently: the vehicle will be more
susceptible to the effects of side winds and
the stability of the vehicle may be affected.
On a long journey, check the security of the
load at every stop.
Remove the roof bars once they are no longer
needed.
