Practical information07
Do not switch off the engine until the filter
is fully regenerated; repeated intervals
can degrade the engine oil prematurely.
Regenerating the filter while the vehicle is
stationary is not recommended.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no impact
on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electric parking brake
This system does not require any routine
servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a dealer or a qualified workshop.
For more information on the Electric
parking brake, refer to the corresponding
section.
Brake pads
Brake wear depends on the style of driving,
particularly in the case of vehicles used in
town, over short distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads are
worn.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a dealer or a qualified
workshop.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure label
are valid for "cold" tyres. If you have driven for
more than 10 minutes or more than 6 miles (10
kilometres) at over 31 mph (50 km/h), add 0.3 bar
(30 kPa) to the values indicated on the label.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely and
have an adverse effect on the vehicle's road
holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the tyres
(tread and sidewalls) and rims as well as the
presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be identified
by this symbol on their sidewalls.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,

165
Practical information07
the shock absorbers have a major impact on road
holding and braking performance.
For your safety and driving comfort, it is important
to have them regularly checked by a dealer or a
qualified workshop.
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
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, the
Manufacturer has taken the decision to equip
its vehicles with a system that combines 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 3,900 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 dealer or a
qualified workshop. After 660 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:
–

U

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

Ne

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

Ne

ver dilute AdBlue
® with water.
You can obtain AdBlue
® from a dealer or a
qualified workshop, as well as service stations
equipped with AdBlue
® pumps specially designed
for passenger vehicles.
Recommendations on storage
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 at room temperature.

166
Practical information07
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
vapours have an irritant effect on mucous
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.
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 an
AdBlue breakdown, you must wait about
5 minutes before switching on the ignition,
without opening the driver's door, unlocking
the vehicle or bringing the electronic key into
the passenger compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
►  Press the "START/STOP" button to switch off
the engine.


►  Turn the blue cap of the AdBlue® tank anti-
clockwise and remove it.
►  With a container of AdBlue®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue
® tank.
►  With an AdBlue® pump: insert the nozzle and
fill the tank until the nozzle automatically cuts
out.
In order not to overfill the AdBlue® tank:
–
Add betw
een 10 and 13 litres using
AdBlue
® containers.
–
St
op after the nozzle’s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
®
intermediate top-ups of 5 litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message “Top
up AdBlue: Starting impossible” – it is essential
to add at least 10 litres.
Top-up detection may not be instantaneous
after addition. It may take a few minutes of
driving before the top-up detection is effective.
Free-wheeling
In certain situations, it is necessary to put the
vehicle into free-wheeling mode (e.g. towing, on
a rolling road, automatic car wash (Wash mode),
rail or sea transport).
The procedure varies according to the type of
gearbox and parking brake.

167
Practical information07
Never leave the vehicle unattended with
the vehicle into free-wheeling mode.
/
Release procedure
►  With the vehicle stationary and the engine
running, select mode N and switch off the engine.
Within 5 seconds:
►  Switch on the ignition.
►  While depressing the brake pedal, move the
push selector forwards or backwards to confirm
mode N.
►  While depressing the brake pedal, press the
control to release the parking brake.
►  Release the brake pedal, switch off the
ignition.
If the 5-second time limit is exceeded, the
gearbox engages mode P; it is then
necessary to restart the procedure.
Reverting to normal operation
►  While depressing the brake pedal, restart the
engine and select mode P.
Keyless Entry and Start
You must not depress the brake pedal
while switching the ignition on again, then
switching it off. If you do, the engine will start,
requiring you to restart the procedure.
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!
