Driving
Operating limits
The regulation range is limited to a maximum
difference of 19 mph (30 km/h) between the
cruise speed setting and the speed of the
vehicle in front.
Above this, the system pauses itself if the safety
distance becomes too short.
The adaptive cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
–

if the vehicle in front slows down too much or
too suddenly

, and the driver does not brake,
–

if a vehicle comes between your vehicle and
the vehicle in front,
–


if the system does not slow the vehicle enough
to continue to maintain a safe distance, for
example when descending a steep hill.
Cases of non-detection by the radar:
–


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


V
ehicles driving in the opposite direction.
When the driver must suspend the cruise
control system:


– When following a narrow vehicle.

– Vehicles not running in the middle of the lane.

– Vehicles entering a corner.
– V ehicles changing lane at the last moment.
Reactivate cruise control when conditions permit.
Cases where the driver is urged to take back
control immediately:
–

When a vehicle cuts in sharply between your
vehicle and the one in front.
–


Excessively sharp deceleration of the vehicle
in front of you.
The adaptive cruise control operates by day and night, in fog or moderate rainfall.
The system does not act on the braking system, but works only with engine
braking.
The regulation range is limited: there will
no longer be any adjustment of speed if the
difference between the programmed speed
setting and the speed of the vehicle in front
becomes too great.
If the difference between the
programmed speed setting and the
speed of the vehicle in front is too great, the
speed cannot be adjusted: the cruise control
is automatically deactivated.
Malfunction
In the event of a malfunction with the adaptive
cruise control, you will be alerted by an audible
signal and the display of the message "Driving
aid functions fault".
Have it checked by a PEUGEOT dealer or a
qualified workshop.

qualified workshop.
Distance Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front, or
with 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 vehicle configuration menu with the audio
system or touch screen.
►

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

168
Driving
threshold chosen by the driver, several different
levels of alert may be triggered and displayed on
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,
steering wheel, etc.) to trigger the alert at the
most relevant moment.
Level 1 (orange): visual alert only,
warning that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
warning that a collision is imminent.
The message "Brake! " is displayed.
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 the "Near " trigger threshold has been
selected.
Intelligent emergency
braking assistance (iEBA)
If the driver brakes, but not sufficiently to avoid
a collision, this system will provide additional
braking, within the limits of the laws of physics. This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates subject to the following
conditions:
–

The vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a cyclist
is detected.
–

The vehicle's speed is between 6 mph and
53 mph (10

km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle
is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With an automatic gearbox, in the event of
automatic emergency braking bringing the
vehicle to a complete stop, keep the brake pedal
depressed to prevent the vehicle from moving
off again.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may 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

–

In certain extreme weather conditions:
fog, heavy rain, snow

, shade, bright sunlight
or direct exposure to the sun (e.g. low sun,
leaving a tunnel).
Distraction detection
Refer to the General recommendations
on the use of driving and
manoeuvring aids.
Depending on version, the function consists of
either the "Driver Attention Alert" system alone
or combined with the "Driver Attention Alert 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.
Activation/Deactivation
This function is set via the vehicle configuration menu.
The state of the system is memorised when the
ignition is switched off.
Driver Attention Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65
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 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65
km/h).
Driver Attention Alert by
camera
Depending on version, the "Driver Attention Alert"
may be combined with the "Driver Attention Alert
by camera".


Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65
km/h)).
At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: 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 markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Blind Spot Monitoring
Refer to the General recommendations
on the use of driving and
manoeuvring aids.


This system includes sensors, placed on the
sides of the bumpers, and warns the driver of

174
Driving
Malfunction

qualified workshop.
Visiopark 1
Refer to the General recommendations
on the use of driving and
manoeuvring aids.


As soon as reverse gear is engaged with the
engine running, this system displays views of
your vehicle’s close surroundings on the touch
screen using a camera located at the rear of the
vehicle.




The screen is divided into two parts with a
contextual view and a view from above the
vehicle in its close surroundings.
The parking sensors supplement the information
on the view from above the vehicle.
Various contextual views may be displayed:
–
Standard view
.
–

180° view
.
–

Zoom view
.
AUTO mode is activated by default.
In this mode, the system chooses the best view
to display
(standard or zoom).
You can change the type of view at any time
during a manoeuvre.
The system status is not saved when the ignition
is switched off.
Principle of operation

Using the rear camera, the vehicle's close
surroundings are recorded during manoeuvres
at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
The display disappears above approximately 6 mph (10 km/h).
The system is automatically deactivated
about 7 seconds after coming out of reverse
or on opening a door or the boot.
Activation
Activation is automatic on engaging reverse gear
at a speed lower than 6 mph (10 km/h).

Practical information
Compatibility of fuels
Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only Diesel fuel additives authorised for use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly
. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50
% full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 69 litres.
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached,
one of these warning lamps lights
up on the instrument panel, accompanied by the
display of a message and an audible signal.
When it first comes on, about 8 litres of fuel
remain.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
A small arrow by the warning lamp indicates which side of the vehicle the
fuel filler flap is located on.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
At least 8 litres of fuel must be added, in order to
be registered by the fuel gauge.
Opening the filler cap may create a noise caused
by an inrush of air. This is entirely normal and
results from the sealing of the fuel system.
To refuel in complete safety:
►

Always switch off the engine.
►


Unlock the vehicle using the Keyless Entry
and Starting.


► Open the fuel filler flap.

179
Practical information
7

► With a conventional key, insert the key into
the filler cap, then turn the key to the left.


► Unscrew and remove the filler cap, then
place it on the holder located on the fuel filler
flap.
►

Insert the nozzle and push it in fully (while
pushing on the metal valve A

).
►

Fill the tank. Do not continue past the
third cut-off of the nozzle, as this may cause
malfunctions.
► Put the filler cap back in place and close it by
turning to the right.
►

Push the fuel filler flap to close it (your
vehicle must be unlocked).


If the vehicle is equipped with a sliding
door on its left-hand side, do not open it
while the fuel filler flap is open (risk of
damaging the fuel filler flap and the sliding
door and risk of injuring the person filling up).
If the fuel filler flap is open and you try to
open the left-hand side door, a
mechanism prevents it from being opened.
The door can be opened half-way, however.
With a mechanical door, close the fuel filler
flap to regain use of the door.
With an electric door, to be able to use it
correctly, close the fuel filler flap and then
press an opening control.
The vehicle is fitted with a catalytic converter,
which helps to reduce the level of harmful
emissions in the exhaust gases.
If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
Fuel cut-off
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
Diesel misfuel prevention
Mechanical device which prevents filling the tank
of a Diesel vehicle with petrol. It helps avoid the
risk of engine damage that can result from filling
with the wrong fuel.
Located in the filler neck, the misfuel prevention
device appears when the filler cap is removed.


When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.

180
Practical information
High-pressure washing
To avoid damaging the electrical
components, it is expressly prohibited to
use high-pressure washing in the engine
compartment or under the body.
Do not use a pressure greater than 80 bar
when washing the bodywork.
Never allow water or dust to enter the
connector or charging nozzle - risk of
electrocution or fire!
Never connect / disconnect the charging
nozzle or cable with wet hands - risk of
electrocution!
Traction battery
This battery stores the energy that powers
the electric motor and the thermal comfort
equipment in the passenger compartment. It is
discharged during use, and must therefore be
regularly recharged. There is no need to wait
for the traction battery to fall to its reserve level
before recharging.
Battery life may vary according to the type of
driving, the route, thermal comfort equipment
usage and battery component ageing.
The traction battery ageing process is influenced by multiple factors, including
climate conditions, the distance travelled and
how often it has been fast-charged.
Do not persist but introduce a Diesel type
filler nozzle.
It is still possible to use a fuel can to fill
the tank slowly.
In order to ensure a good flow of fuel, do
not place the nozzle of the fuel can in direct
contact with the flap of the misfuel prevention
device.
Driving abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with misfuel
protection, so before travelling abroad,
we recommend that you check with the
PEUGEOT dealer network, whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
Charging system
(Electric)
400 V electrical system
The electrical traction system, which operates at
a voltage of approximately 400 V, is identified by
orange cables, and its components are marked
with this symbol:


An electric vehicle’s power train can become hot during use and after
switching off the ignition.
Observe the warning messages shown on
labels, particularly inside the flap.
All work on or modifications to the vehicle’s
electrical system (including the traction
battery, connectors, orange cables and
other components visible from the interior or
exterior) is strictly prohibited - risk of severe
burns or potentially fatal electric shock
(short-circuit/electrocution)!
In the event of a problem, always contact a
PEUGEOT dealer or a qualified workshop.


This label is intended solely for use by firefighters and maintenance services in
the event of any work on the vehicle.
No other person must touch the device shown
on this label.
In the event of an accident or impact
to the vehicle’s underbody
In these situations, the electrical
circuit or the
traction battery can be seriously damaged.
Stop as soon as it is safe to do so and switch
off the ignition.
Contact a PEUGEOT dealer or a qualified
workshop.
In the event of exposure to a fire
Immediately exit and evacuate all
passengers from the vehicle. Never attempt
to fight the fire yourself - risk of electrocution!
You must immediately contact the emergency
services, informing them that the incident
involves an electric vehicle.
When washing
Before washing the vehicle, always
check that the charging flap is closed
correctly.
Never wash the vehicle while the battery is
on charge.
