On an ascending slope, with the vehicle
stationary, the vehicle is held for a short time
when you release the brake pedal:
–
provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a short time when you
release the brake pedal.
Malfunction
These warning lamps come on in the event of a malfunction.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
Active Suspension Control
This suspension adapts itself to the following
parameters: state and profile of the road, load
of the vehicle, driving style and selected driving
mode.
It is managed by a computer, which interprets
the data transmitted by different sensors to
apply the optimal level of damping to each shock
absorber.
It offers three modes: Comfort, Normal and
Sport.
The mode can be selected using the DRIVE
MODE control on the central console.
For more information on the Driving modes,
please refer to the corresponding section.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using the following
control:




Pressing the control displays the modes on the
instrument panel.
When the message disappears, the selected
mode is activated and remains indicated on the
instrument panel (except NORMAL mode).
With petrol / Diesel engines
Whenever the ignition is switched on, NORMAL
mode is selected by default.
ECO
This mode reduces fuel consumption, but
restricts the performance of the heating and
air conditioning systems, without however
deactivating them.
Free-wheeling in ECO mode: depending on
version, with the EAT8 gearbox, moving into
"free-wheeling" is encouraged to slow the vehicle
down without using engine braking. You can
save fuel by anticipating the need to slow down
and lifting your foot fully off the accelerator pedal.

108
Driving
COMFORT
(with Active Suspension Control)
Allows more comfortable driving and softer
suspension.
NORMAL
Restores the vehicle’s original settings.
Together with Active Suspension Control, this
mode offers the best compromise between
comfort and handling.
SPORT
Enables more dynamic driving, acting on the
power steering, accelerator and gear changes
with an automatic gearbox and the possibility of
displaying the vehicle’s dynamic settings on the
instrument panel.
MANUAL
Permanent "Manual" mode with an automatic
gearbox and Full Park Assist.
Enables manual gear changing using the
steering-mounted paddles.
With hybrid engine
Each time the ignition is switched on, ELECTRIC
mode is selected by default.
ELECTRIC
Allows 100% electric driving. The maximum
speed is approximately 84 mph (135 km/h).
When starting the vehicle, if the conditions do not
allow the activation or retention of

ELECTRIC

mode, the message
“Electric mode currently
unavailable” is displayed in the instrument panel.
The vehicle automatically changes to HYBRID
mode.
The lighting of a blue LED under the interior
rear view mirror, visible from outside the vehicle,
confirms driving in ELECTRIC mode.
The lighting of the LED can be
deactivated by inserting the tip of a paper
clip type accessory into the hole under the
mirror
.
Conditions of activation
–

Adequate battery charge level. Charging
the vehicle after each drive is therefore
recommended.

The ELECTRIC mode is
available as long as there is power left in the
battery.
–

Exterior temperature between 0°C and 45°C.
Manually exiting the mode
–


Fully depress the accelerator pedal.
–


Select another mode.
In case of non-use of the vehicle for a
long period (several months), a restart of
the petrol engine may occur even if the
battery is charged.
HYBRID
Optimises the fuel consumption of the vehicle
by managing the alternating or simultaneous
operation of the two types of engine ,
according to road conditions and driving style.
In HYBRID mode, it is possible to drive in
100% electric mode if the battery charge level
is sufficient and acceleration requirements are
moderate.
When navigation is activated, the use
of HYBRID mode is advisable to optimise
electrical consumption.
SPORT
Allows more dynamic driving to take advantage
of the vehicle's maximum performance.
Electric power is used to supplement the petrol
engine as long as there is energy left in the
battery.
COMFORT
Depending on equipment.
Combines the HYBRID mode and Active
Suspension Control (controlled shock absorption
option).
In COMFORT mode, the suspension favours soft
shock absorption to improve driving comfort on
uneven surfaces.
For more information on Active
Suspension Control , refer to the
corresponding section.
Gear efficiency indicator
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may advise
skipping one or more gears.
Gear engagement recommendations are only
optional. In fact, the configuration of the road,
the traffic density and safety remain determining
factors when choosing the best gear. Therefore,
the driver remains responsible for deciding
whether or not to follow the system’s advice.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears in the instrument panel in the form of an arrow and the
recommended gear.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never suggests:

Driving
6The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
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) as well as 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 fuel 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 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 does not always cause visible bulging 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 the four tyres when cold.
►

If it is not possible to make 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).
The alert is kept active until the system is reinitialised.
Reinitialisation
Reinitialise the system after adjusting one or
more tyre pressures 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 is
reinitialised via the Driving /
V
ehicle touch screen menu..
Malfunction
These warning lamps come on in the event of a malfunction.
A message appears, accompanied by an audible
signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a PEUGEOT
dealer or a qualified workshop.

6Changing a speed setting
Speed settings can be activated,
deactivated, selected and changed in the
Driving
/ Vehicle touch screen menu.
"MEM" button



With this button, you can select a memorised
speed setting to use with the speed limiter or the
programmable cruise control.
For more information on the Speed limiter
or Cruise control, refer to the corresponding
section.
Drive Assist Plus
Only available on versions with automatic
gearbox.
This system automatically adjusts the speed and
corrects the trajectory, using the Adaptive Cruise
Control with Stop
& Go function in conjunction
with the Lane Positioning Assist.
These two functions must be activated and in
operation.
This system is especially suitable for driving on
motorways and main roads.
For more information on Adaptive Cruise
Control and Lane Positioning Assist, refer to
the corresponding sections.
The system assists the driver by acting on the steering, acceleration and braking,
within the limits of the laws of physics and the
capabilities of the vehicle. Certain road
infrastructure elements or vehicles present on
the road may not be properly seen or may be
poorly interpreted by the camera and radar,
resulting in an unexpected change in
direction, a lack of steering correction and/or
inappropriate management of acceleration or
braking.
Adaptive Cruise Control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically maintains the speed
of your vehicle at a value which you set (speed
setting), while keeping a safe distance from the
vehicle in front (target vehicle), and which has
been set beforehand by the driver. The system
automatically manages the acceleration and
deceleration of the vehicle.
With the Stop function , the system manages
the braking until the vehicle comes to a complete
stop.
With the Stop & Go function , the system
manages the braking until the vehicle comes to a
complete stop and the restarting of the vehicle.


To do so, it has a camera located at the top of
the windscreen and, depending on version, a
radar located in the front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver operates a direction indicator
to overtake a slower vehicle, the cruise
control allows the vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, without ever
exceeding the speed setting.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar (e.g. a
lorry), which may lead to a poor assessment
of the distances and lead to the vehicle
inappropriately accelerating or braking.

Distance Alert
This function warns the driver that their vehicle is
at risk of a collision with the vehicle in front, or a
pedestrian or cyclist present in their traffic lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the Driving / Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "Far", "Normal" or "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
