► Do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
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 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.
►  Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a dealer.
Starting/switching off the
engine
The electronic key must be present in the
passenger compartment.
If the electronic key is not detected, a message
is displayed.

Driving06
– The outside temperature must be between 0°C
and 35°C.
Putting the engine into standby (STOP
mode)
The engine automatically enters standby mode
as soon as the driver indicates their intention to
stop:
–

With an automatic gearbo
x, at speeds below
12 mph (20 km/h) on BlueHDi versions, or below
2 mph (3 km/h) on PureTech 130, 180 and 225
versions, when you depress the brake pedal or
place the gear selector in mode N.
Time counter
A time counter adds up the time spent in standby
during the journey. It is reset to zero every time
the ignition is switched on.
Special cases:
The engine will not go into standby if the
conditions for operation are not met and in the
following cases:
–

St
eep slope (ascending or descending).
–

Needed t
o maintain a comfortable temperature
in the passenger compartment.
–

Demisting activ
e.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).
During parking manoeuvres, STOP mode is
not available for a few seconds after
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:
–

With the select
or in mode D or M: with the
brake pedal released.
–

With the select
or in mode N and the brake
pedal released: with the selector at D or M.
–

With the select
or in mode P and the brake pedal
depressed: with the selector at R, N, D or M.
–

With re
verse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following cases:
–
V
ehicle speed exceeds 2.5 mph (4 km/h) with
PureTech 130, 180 and 225 versions, or 16 mph
(25 km/h) with BlueHDi versions.
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a 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.
►  Switch off the ignition then start the engine
again with the "START/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 dealer or
a qualified workshop.
Tyre under-inflation
detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving, not
when stationary.
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.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.

Driving06
This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the system
via the driving aids touch screen application is
recommended, for instance:
–

T
owing a trailer (particularly a trailer without
its own braking system).
–

Carrying long objects on roo
f bars.
–

D
riving with snow chains.
–

U
sing an automatic car wash.
–

Performing an
y maintenance (e.g. changing a
wheel, working inside the engine compartment).
–

Placing the v
ehicle on a rolling bench in a
workshop.
–

T
owing the vehicle.
–

Follo
wing an impact to the windscreen close to
the detection camera.
The system is automatically deactivated
once the use of a different diameter
"space-saver" type spare wheel is detected, or
if a fault with the two lateral brake lamps is
detected.
The system diagnoses permanently its
capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions
(e.g. sensor initialization, board voltage out of
regular range, activation of stability system).
Therefore, the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle
(keep within the GVW limit and load
height limits for roof bars).
Following an impact (e.g.  a collision), the
system is automatically deactivated.
Have it checked by a dealer or a qualified
workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
►  Select one of the 3 preset
thresholds: "Far ", "Medium" or "Near".
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own vehicle
and the object identified for the collision risk, and
the operation of the vehicle (e.g. actions on the
pedals, steering wheel) to trigger the alert at the
most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake!" is displayed.
Level 3: a micro-braking may be given, confirming
the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically at
lower speed.

Advice on care and
maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.
Exterior
Never use a high-pressure jet wash in the
engine compartment - risk of damaging
the electrical components!
Do not wash the vehicle in bright sunshine or
extremely cold conditions.
When washing the vehicle in an automatic
roller-brush car wash, be sure to lock the
doors and, depending on version, move the
electronic key away and deactivate the
"hands-free" function (Hands-Free Tailgate
Access).
When using a pressure washer, keep the jet
nozzle at a minimum distance of 30 cm from
the vehicle (particularly when cleaning areas
containing chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's
paintwork (including tree resin, bird droppings,
insect secretions, pollen and tar).
Depending on the environment, clean the
vehicle frequently to remove salty deposits
(in coastal areas), soot (in industrial areas)
and mud/salts (in wet or cold areas). These
substances can be highly corrosive.
Contact a dealer or a qualified workshop for
advice on removing stubborn stains requiring
special products (such as tar or insect
removers).
Preferably, have paint touch-ups performed by
a dealer or a qualified workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure jet to clean
the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
damage to the instruments and controls and
the controls located on the centre console. Be
vigilant!
To clean instrument panels, touch screens
or other displays, wipe gently with a soft,
dry cloth. Do not use products (e.g. alcohol,
disinfectant) or soapy water directly on these
surfaces - risk of damage!

Vehicle data recording and privacy11
Vehicle data recording and
privacy
Electronic control units are installed in your
vehicle. These control units process data received
from the vehicle's sensors, for example, or data
they generate themselves or exchange with
each other. Some of these control units are
required for the correct operation of your vehicle,
some others assist you while driving (driving or
manoeuvring aids), while others provide comfort
or infotainment functions.
The following contains general information about
how data is processed within the vehicle.
You will find additional information about the
specific data which is downloaded, stored
and transmitted to third parties and what it
is used for in your vehicle under the keyword
"Data protection". This information is directly
associated with the references for the functions
in question contained in the corresponding
vehicle handbook, or in the general terms and
conditions of sale.
This information is also available online.
Vehicle operating data
The control units process the data used for the
operation of the vehicle.
This data includes, for example:
–
In
formation about the state of the vehicle
(e.g. speed, travel time, lateral acceleration,
wheel rotation rate, fastened seat belts display). –

En
vironmental conditions (e.g. temperature,
rain sensor, distance sensor).
As a general rule, this data is temporary, is
not stored for longer than one operating cycle
and is only used within the vehicle itself. The
control units often record this data (including
the vehicle's key). This function allows either the
temporary or permanent storage of information
about the state of the vehicle, stresses on
components, servicing requirements, as well as
events and technical errors.
Depending on the vehicle's equipment level, the
data stored is as follows:
–
O
perating state of system components
(e.g. filling level, tyre pressures, battery charge
status).
–
Faults and malfunctions in import
ant system
components (e.g. lamps, brakes).
–
Sy
stem reactions in specific driving situations
(e.g. deployment of an airbag, triggering of
stability control and braking systems).
–
In
formation about events which have damaged
the vehicle.
–
For electric and rechargeable h
ybrid vehicles,
the traction battery charge level and the
estimated driving range.
In particular circumstances (e.g. if the vehicle has
detected a malfunction), it may be necessary to
record data which would otherwise simply not be
stored.
When taking your vehicle in for servicing
(e.g. repairs, maintenance), the stored operating
data may be read along with the vehicle's identification number and used if necessary.
The personnel working for the servicing network
(e.g. garages, manufacturers) or third parties
(e.g. roadside assistance agents) may read the
vehicle's data. This also applies to work carried
out under warranty and quality assurance
measures.
This data is generally read via the OBD (On-Board
Diagnostics) port fitted by law to the vehicle. It
is used to report on the technical state of the
vehicle or its components and facilitates the
diagnosis of malfunctions, in compliance with
warranty obligations and for quality improvement.
This data, in particular the information relating
to stress on components, technical events,
operator errors and other malfunctions, is
sent to the Manufacturer, if necessary, along
with the vehicle's identification number. The
Manufacturer's liability may also be engaged. The
Manufacturer may also use the operating data
taken from the vehicle for product recalls. This
data may also be used to check the customer's
warranty and any claims made under warranty.
Any malfunctions stored in the vehicle may be
reset by an after-sales service company during
servicing or repair work, or at your request. Comfort and infotainment
functions
Comfort settings and personalised settings
may be saved in the vehicle and modified or
reinitialised at any time.
