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.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when the
driver releases the brake pedal:
–

If mode
D or M is selected on an automatic
gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when the driver releases the
brake pedal.
Malfunction
If the event of a malfunction, these
warning lamps light up on the
instrument panel, accompanied by the display of
a message.
Have it checked by a PEUGEOT dealer or a
qualified workshop.

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).

132
Driving
The brake pedal may feel hard and vibrate slightly while the function is
operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to
2

seconds.
Deactivation/Activation
By default, the system is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
The system cannot be deactivated above 10 km/h.
Malfunction
This warning lamp lights up on the instrument panel with the message
"Driving Assistance Sensor blind: Clean
sensor, see User Manual" if the sensor is
masked.
This is a normal behavior, which does not
request the support of a qualified workshop.
In this case, stop the vehicle and verify if the
front camera or the front radar is covered by dirt,
mud, sand, snow, ice or anything preventing the
sensing.
The system is operational again after the
detection field has been cleaned.
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.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.
These warning lamps light up on the instrument panel and/or in the
warning lamp display for seat belts and front
passenger airbag to indicate that the driver's
and/or front passenger's seat belt is not fastened
(depending on version). The automatic braking
system is deactivated until the seat belts are
fastened.
Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The function comprises the "Driver Attention
Warning" system combined with the "Driver
Attention Warning by Camera" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Driver Attention Warning
The system triggers an alert when it detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).

133
Driving
6Driver Attention Warning by
Camera


The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
The system may perform a learning procedure for up to 30 minutes after the
start of the monitoring.
During this period, the driver's individual
driving behaviour is analysed and no alert is
given.
At a first alert level, the driver is warned by
the message "Caution!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Driving at
risk: Take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.
The following situations may interfere with the operation of the system or
prevent it from working:
–

Lane positioning assist is active.
–


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).
–

windscreen area located in front of the
camera (e.g.

dirty, misted, frost-covered,
snow-covered, damaged or masked by a
sticker).
–

lane markings absent, worn, hidden
(e.g.

snow, mud, dead leaves) or multiple
(roadworks).
–

close to the vehicle ahead (lane markings
not detected).
–

Visiopark 1
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
When reverse gear is engaged, with the engine
running, this system displays views of the
vehicle's close surroundings on the touch screen
using a camera located at the rear of the vehicle.




The screen is divided into 3 parts with a side
menu, a contextual view and a view from above
the vehicle in its close surroundings.
The parking sensors supplement the information
in the view from above the vehicle.
Different contextual views are available:
–
Automatic zoom view
.
–

Standard view
.
–

Panoramic view
.
Depending on the context, the system chooses
the best view to display (standard or automatic
zoom).
The view type can be changed at any time
during the manoeuvre.
The system status is not saved when the ignition
is switched off.
Operating principle

Using the camera, the vehicle's close
surroundings are recorded during low speed
manoeuvres.
An image from above the vehicle in its close
surroundings is created in real time (on the side
of the screen), as the vehicle progresses.
This view makes it easier to align the vehicle
when parking and to perceive nearby obstacles.
It is automatically deleted if the vehicle remains
stationary for too long.
Settings
In the side menu:This window allows to carry out the following operations:
–

adjust the volume of the audible signal.

Practical information
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery with
special technology and specifications.
Its replacement should be carried out only by
a PEUGEOT dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting of this
warning lamp, accompanied by an alert
message.
As soon as traffic conditions allow, regenerate
the filter by driving at a speed of at least
37
mph (60 km/h), with an engine speed above
2,500
rpm, for about 15 minutes (until the
warning lamp goes out).
If it is not possible to reach 37
mph (60 km/h),
leave the engine running at idle for about 15
minutes, then drive with an engine speed above
2,500
rpm for 15 minutes.
Do not switch off the engine until the filter
is fully regenerated; repeated intervals
can degrade the engine oil prematurely.
Regenerating the filter while the vehicle is
stationary is not recommended.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a PEUGEOT dealer or a qualified
workshop.
For more information on the Electric
parking brake, refer to the
corresponding section.
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
