Safety
► Press the central part of the steering wheel.
Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
–

Anti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
–


T
railer stability assist (TSA).
Anti-lock braking system (ABS) and Electronic brake
force distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the
event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a PEUGEOT dealer or a qualified
workshop as soon as possible.
This warning lamp, when lit together with the ABS warning lamp, accompanied by a
message and an audible signal, indicates an
EBFD malfunction.
You must stop as soon as it is safe to do so.
Contact a PEUGEOT dealer or a qualified
workshop.
The normal operation of the ABS may result in slight vibrations in the brake
pedal.
When braking in an emergency, press
very firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems checked by a PEUGEOT dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an
increase in braking efficiency.
Anti-slip regulation (ASR)
/ Dynamic stability control
(DSC)
Anti-slip regulation optimises traction using
engine braking and by applying the brakes on
the driving wheels to avoid wheel spinning. It
also enhances the vehicle's directional stability
while accelerating.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This warning lamp on the instrument panel flashes to indicate that they are
operating.
Deactivation/Reactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
these systems, so that the wheels can turn freely
and regain grip.

Safety
5With GTi version

► Press this button to deactivate DSC
and ASR.
Except GT
i version
► Select " Traction control " from the
"Driving functions " menu on the touch
screen to deactivate ASR.
Deactivation is confirmed when this
indicator lamp is displayed on the
instrument panel accompanied by a message
and, depending on version, the lighting of the
indicator lamp in the button.
Reactivate the system(s) when normal grip is
restored.
This/these system(s) is/are reactivated
automatically each time the ignition is switched
off or above 31 mph (50
km/h) (except GTi
version).
Below 31 mph (50
km/h), reactivate them
manually.
With GTi version
► Press this button again to reactivate
DSC and ASR.
Except GTi version
► Select Traction control from the
Driving functions menu on the touch
screen to reactivate ASR.
Malfunction
In the event of a malfunction of these
systems, this warning lamp comes on,
accompanied by the display of a message and
an audible signal.
Contact a PEUGEOT dealer or a qualified
workshop to have the systems checked.
ASR / DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures used by PEUGEOT
dealers.
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC)
must not have any faults.
At speeds between 37 and 99 mph (60 and
160
km/h), if the system detects oscillating trailer
movements (snaking), it applies the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow the vehicle.
This warning lamp flashes on the instrument panel and the brake lamps
light up to draw attention to this corrective action.
For information on weights and towed loads,
refer to the Engine Technical Data and Towed
Loads section or your vehicle’s registration
certificate
To ensure safe driving with a Towing device,
refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp comes
on in the instrument panel, accompanied
by a message and an audible signal.
If you wish to continue towing a trailer, reduce
your speed and drive carefully!
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.

Driving
Starting with the key
The parking brake must be applied.
► With a manual gearbox in neutral, fully
depress the clutch pedal.
► With an automatic gearbox in mode P or N,
fully depress the brake pedal.
► Insert the key into the ignition switch.
– The system recognises the starting code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In some cases, you may have to apply
some force to turn the wheels (if the
wheels are turned against a kerb, for
example).
► With a petrol engine, operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. As soon as the engine starts, release the
key.
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
► Wait until this warning lamp goes off in
the instrument panel, then turn the key to
position 3 without pressing the accelerator pedal,
to operate the starter motor until the engine
starts. As soon as the engine starts, release the
key.
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine PEUGEOT towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes after
the ignition is switched off, and prevents the
engine being started by anyone who does not
have the key.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message in the screen.In
this case, your vehicle will not start; contact a
PEUGEOT dealer as soon as possible.
Keep safely, away from your vehicle, the
label attached to the keys given to you

The system is automatically deactivated when the use of a "space-saver" type
spare wheel is detected, or if a fault with the
lateral brake lamps is detected.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function automatically stops operating. Contact a
PEUGEOT dealer or a qualified workshop to
have the system checked.
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 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.
►

Select one of the three pre-defined
thresholds:
–

"Distant".
–
“Normal".
–
“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,
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
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.

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.
Malfunction
A fault in the system is signalled by the fixed illumination of this warning lamp,
accompanied by the display of a message and
an audible signal.
Contact a PEUGEOT dealer or a qualified
workshop to have the system checked.
These warning lamps come on if the driver's seat belt and/or front
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.
It is the driver’s responsibility to stop if feeling
tired.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
