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,

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!

power supply for long enough to repair a tyre
after a puncture.
Tyre inflation pressures are indicated on
this label.
For more information on Identification
markings, particularly this label, refer to the
corresponding section.
For more information on the Tool kit, refer
to the corresponding section.
Repair procedure
Do not remove any foreign body (e.g. nail,
screw) which has penetrated the tyre.
►  Park the vehicle without obstructing traffic
and apply the parking brake.
►  Follow the safety instructions (hazard warning
lamps, warning triangle, high visibility jacket,
etc.) according to the legislation in force in the
country in which you are driving.
►  Switch the ignition off.


► Remove the transparent cap from the bottle
of sealant.
►  Lift the protective cover before installing the
bottle of sealant on the compressor.
►  Turn the bottle of sealant over and screw it a
quarter turn into the compressor.
►  Remove the valve cap from the tyre to be
repaired, and place it in a clean place.


►  Uncoil the pipe stowed under the compressor.
►  Connect the pipe from the compressor to the
valve of the tyre to be repaired and tighten firmly.
►  Check that the compressor switch is in
position "O".
►  Fully uncoil the electric cable stowed under
the compressor.
►  Connect the compressor's electric plug to the
vehicle's 12 V socket.
►  Affix the speed limit sticker.
The speed limit sticker must be affixed
inside the vehicle in the area close to the
driver, to remind them that a wheel is in
temporary use.
►  Switch the ignition on.


► Switch on the compressor by moving the
switch to position "I" until the tyre pressure
reaches 2 bar. The sealant product is injected
under pressure into the tyre; do not disconnect
the pipe from the valve during this operation (risk
of blowback).
If after approximately 7 minutes, the
pressure of 2 bar is not reached, this
indicates that the tyre is not repairable;
contact a dealer or a qualified workshop for
assistance.

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not
obstruct traffic: the ground must be level,
stable and non-slippery.
Select mode P on the automatic gearbox to
lock the wheels, apply the parking brake,
unless it is set to automatic mode, and switch
off the ignition.

176
In the event of a breakdown08
Check that the parking brake indicator lamps
on the instrument panel are on fixed.
The occupants must get out of the vehicle and
wait where they are safe.
If necessary, place a chock under the wheel
diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel, first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel, refit the wheel trim,
starting by placing its aperture in line with the
valve and then pushing it into place all round
its edge with the palm of your hand.




►  To remove the wheel bolt cover on each of the
bolts, use tool 7 (alloy wheels).
►  Fit security socket 2 on wheelbrace 5 to
slacken the security bolt.
►  Slacken the other bolts using the
wheelbrace 5 only.
Never use an impact wrench on the
security bolt socket.


►  Place the foot of jack 6 on the ground and
ensure that it is directly below the front A or
rear B jacking point on the underbody, whichever
is closest to the wheel to be changed.


►  Extend jack 6 until its head comes into contact
with jacking point A or B; contact area A or B on
the vehicle must be properly inserted into the
central part of the head of the jack.
►  Raise the vehicle until there is sufficient space
between the wheel and the ground to easily admit
the spare (not punctured) wheel.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area on the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!
