Driving
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again.
With a manual gearbox: with the clutch pedal
fully depressed.
With an automatic gearbox:
–
With the selector in position D

or M: with the
brake pedal released.
–

With the selector in position N

and the brake
pedal released: with the selector at D or M.
–

With the selector in position P

and the brake
pedal depressed: with the selector at R, N, D
or M.
–

Reverse gear engaged.
Special cases
The engine will restart automatically if all
conditions for operation are met again and in the
following cases.
–
With a
manual gearbox: vehicle
speed
exceeds 16 mph (25 km/h) or 2 mph (3
km/h) (depending on the engine).
–

With an
automatic gearbox, vehicle speed
exceeds 2 mph (3
km/h).
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
Depending on the vehicle’s equipment:In the event of a system malfunction, this
warning lamp flashes on the instrument
panel.
The warning lamp in this button flashes and a message appears, accompanied by
an audible signal.
Have it checked by a PEUGEOT dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
Depending on version, a warning message
may also be displayed, prompting you to place
the gear selector in position N and depress the
brake pedal.
►

Switch off the ignition then start the engine
again with the key or the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
PEUGEOT
dealer or a qualified workshop.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The 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 specified 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.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
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 may not always cause visible deformation 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 all four tyres when cold.
► If it is not possible to carry out 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).

154
Driving
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected
by the accumulation of dirt (e.g.
mud, ice),
in poor weather conditions (e.g.
heavy rain,
snow), or if the bumpers are damaged.
If the front bumper is to be repainted, contact
a PEUGEOT dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar(s).


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a PEUGEOT dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
terrain.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors, as well as
any associated functions, may be disrupted
by noise pollution such as that emitted by
noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
PEUGEOT may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
– Ensure that the mat is secured correctly.
– Never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
in the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required

When stationary or while driving, no
objects should be placed around the
projection blade (or in its recess) so as not to
impede its movement and correct operation.
In certain extreme weather conditions
(rain and/or snow, bright sunshine, etc.),
the head-up display may not be legible or
may suffer temporary interference.
Some sunglasses may hamper reading of the
information.
To clean the projection blade, use a clean,
soft cloth (such as a spectacles cloth or
microfibre cloth). Do not use a dry or abrasive
cloth, or detergent or solvent products, due to
the risk of scratching the projection blade or
damaging the non-reflective coating.
This system operates when the engine is running, and the settings are saved when
the ignition is switched off.
Memorising speeds
This function allows you to save speed
settings which are then used to set the two
systems: the speed limiter (limits the speed
of the vehicle) or cruise control (vehicle
cruising speed).
You can save 6 speed settings for each of the
two systems.
Programming
The speed thresholds can be set in the vehicle configuration menu using the
touch screen.

Speed Limit Recognition
and Recommendation
Refer to the General recommendations
on the use of driving and
manoeuvring aids.


This system displays the maximum authorised
speed on the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.
– Speed limit information from the navigation
system’s mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account to ensure
you observe the speed limit.

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.
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
(iEBA).
– Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen and, depending on version, a
radar located in the front bumper.
This system does not replace 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.
