Active Safety Brake with Distance Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
–
warns the driver that their vehicle is at risk of
collision with the vehicle in front.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
This system is comprised of three functions:
–

Distance Alert.
–


Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.

11 4
Driving
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.
Driving time starts being counted again once
the speed reaches 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".

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 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 pressed down 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.

passenger seat belt (depending on version) are
not fastened.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break if you are feeling tired or at least
every 2 hours.
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.

Practical information
Towing device
Load distribution
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle, and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance.
The maximum towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and their
wiring harnesses approved by
PEUGEOT. We recommend having them
fitted by a PEUGEOT dealer or a qualified
workshop.
If not fitted by a PEUGEOT dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical
data section of this guide.
Complying with the maximum authorised
nose weight (towball weight) also includes
the use of accessories (bicycle carriers,
tow boxes, etc.).
Observe the legislation in force in the
country where you are driving.
GTi towing
Your vehicle cannot be fitted with a
tow-bar.
Towing device with towball
Before each use
To ensure the towball is correctly fitted,
check the follow points:
Saloon:
–

The green mark on the wheel is in line with
the green mark on the towball.
–


The wheel is in contact with the towball
(position A

).
–

The safety lock is on and the key removed;
the wheel can no longer be operated.
–


The towball must not be able to move in
its carrier; test by attempting to move it with
your hand.
SW :
–


The towball is correctly engaged (position
A

).
–

The safety lock is on and the key removed;
the trigger can no longer be operated.
–


The towball must not be able to move in
its carrier; test by attempting to move it with
your hand.
If the towball is not engaged, the trailer can
become detached -

Accident risk!
During use
Never release the locking system when
a trailer or load carrier is connected to the
towball.
Never exceed the maximum authorised
weight for the vehicle - Gross Train Weight
or GTW.
Always comply with the maximum authorised
load on the towing device: if it is exceeded,
this device may become detached from the
vehicle - risk of an accident!
Check that the trailer lamps work correctly.
Before setting off, check and/or adjust
headlamp beam height.
For more information on Headlamp height
adjustment, refer to the corresponding
section.
Following use
When travelling without a trailer or load
on a towbar-mounted carrier, the towball
must be removed and the protective plug
inserted in the carrier. This measure applies
particularly where the towball might obscure
visibility of the number plate or its lighting.
Blanking plug

In the event of recovery, it is essential to remove
the blanking plug if your vehicle has one.

Practical information
For your safety and driving comfort, it is
important to have them regularly checked by a
PEUGEOT dealer or a qualified workshop.
Only use products recommended by
PEUGEOT or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, PEUGEOT selects and offers
very specific products.
After washing the vehicle, dampness, or in
wintry conditions, ice can form on the brake
discs and pads: braking efficiency may be
reduced. Make light brake applications to dry
and defrost the brakes.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, PEUGEOT
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 4,000
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400

km) before the tank is
empty and the vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a
PEUGEOT dealer or a qualified workshop.
After 685 miles (1,100 km), a device is
automatically activated to prevent the engine
from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–

Use
only AdBlue
® fluid that meets the ISO
22241 standard.
–

Never

transfer AdBlue
® to another container
as it would lose its purity.
–

Never

dilute AdBlue
® with water.
You can obtain AdBlue
® from a PEUGEOT
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles (for versions
with access to the AdBlue
® tank via the fuel
filler flap).
Never top up from an AdBlue® dispenser
reserved for heavy goods vehicles.
Storage recommendations
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out in the ambient air.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia

membranes (eyes, nose and throat).
Store AdBlue® out of the reach of
children, in its original container.
Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11°C. Otherwise the
AdBlue
® may be frozen and so cannot be poured
into the tank. Park the vehicle in a warmer area
for a few hours to allow the top-up to be carried
out.
Never pour the AdBlue® into the Diesel
fuel tank.
For specific information about how to
access the AdBlue tank, refer to the
detailed descriptions below.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off using a
sponge and hot water.
Important: in the event of a top-up after
a breakdown because of a lack of
AdBlue, it is essential to wait around 5
minutes before switching on the ignition,
without opening the driver’s door,
unlocking the vehicle, introducing the key
into the ignition switch, or introducing the
key of the “

Keyless Entry and Starting

”
system into the passenger compartment

.
Switch on the ignition, then wait for 10
seconds before starting the engine.
Access to the AdBlue®
A blue cap under the fuel filler flap indicates
access to the AdBlue® tank.

– Switch off the ignition and remove the key .
