Deactivation / Reactivation
In exceptional conditions (starting a vehicle stuck
in mud, immobilised in snow, on soft ground, etc.),
it may be useful to deactivate the ASR system to
freely spin the wheels and regain traction.
Reactivate the system as soon as the level of grip
permits.
It is set via the Driving / Vehicle touch
screen menu.
Deactivation is confirmed by the
illumination of this indicator lamp in the
instrument panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 31 mph (50 km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this
warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a 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.
For technical reasons, in particular to
improve the quality of telematic services
for customers, the Manufacturer reserves the
right to carry out updates to the vehicle's
on-board telematic system at any time.
If you benefit from the DS CONNECT BOX
offer with the SOS and Assistance Pack
included, you have available additional
services in your personal space, via the
website in your country.
For information about the SOS and Assistance
Pack, please refer to the general conditions for
these services.
Electronic stability control
(ESC)
The electronic stability control programme
includes the following systems:
–

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

Emergenc
y braking assistance (EBA).
–

An
ti-slip regulation (ASR).
–

Dynamic st
ability control (DSC).
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 dealer or a qualified workshop as soon
as possible.
This warning lamp, when lit together with
the STOP and ABS warning lamps,
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 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 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.

Driving06
The system must not be activated in the
following situations:
–

D

riving with a "space-saver" type spare
wheel.
–

When t
owing, especially with an
unconnected or unapproved trailer.
–

Poor w
eather conditions.
–

D

riving on slippery road surfaces (risk of
aquaplaning, snow, ice).
–

D

riving on racing circuits.
–

D

riving on a rolling road.
Malfunction
A system malfunction is indicated
by the Service warning lamp coming
on and this (orange) symbol, accompanied by an
alert message and an audible signal.
Active Lane Departure
Warning System
Refer to the General recommendations on the use
of driving and manoeuvring aids.
Using a camera located at the top of the
windscreen to identify lane markings on the
road and at the edges of the road (depending on
version), the system corrects the trajectory of the
vehicle while alerting the driver if it detects a risk
of unintentionally crossing a line or hard shoulder
(depending on version).
This system is particularly useful on motorways
and main roads.


Conditions for operation
– Vehicle speed between 40 and 112 mph (65 and
180 km/h).
–

R
oad marked with a central dividing line.
–

St
eering wheel held in both hands.
–

Direction indic
ators not activated.
–

ESC s
ystem activated and operational.
The system helps the driver only if there is
a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or brakes.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected or a lane limit (e.g. grass border), it
makes the necessary trajectory correction to
return the vehicle to its initial path.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
The driver can prevent the correction by
keeping a firm grip on the wheel (during
an avoiding manoeuvre, for example).
The correction is interrupted immediately if
the direction indicators are operated.


While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory is
intentional and no correction is triggered during
this period.
However, with the Blind Spot Detection system
activated, if the driver starts changing lanes and
another vehicle is detected in the vehicle's blind
spot, the system will correct the trajectory even
though the direction indicators are on.
For more information on the Blind Spot Detection,
refer to the corresponding section.

Do not use a pressure greater than 80 bar
when washing the bodywork.
Traction battery
This battery stores the energy that powers
the electric motor and the thermal comfort
equipment in the passenger compartment. It is
discharged during use, and must therefore be
regularly recharged. There is no need to wait for
the traction battery to fall to its reserve level
before recharging.
Battery life may vary according to the type of
driving, the route, thermal comfort equipment
usage and battery component ageing.
The traction battery ageing process is
influenced by multiple factors, including
climate conditions, the distance travelled and
how often it has been fast-charged.
In the event of damage to the traction
battery
It is strictly prohibited to work on the vehicle
yourself.
Do not touch liquids coming from the battery,
and in the event of skin contact with these
products, wash abundantly with water and

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a dealer or a
qualified workshop.
The fluids must comply with the
manufacturer's requirements and with
the vehicle's engine.
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a dealer or a qualified
workshop.
Engine oil
The level is checked, with the engine
having been switched off for at least 30
minutes and on level ground, using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended that
you check the level, and top up if necessary, every
3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►  Grasp the dipstick by its coloured grip and pull
it out completely.

►  Grasp the dipstick by its coloured grip and pull
it out completely.
►  Wipe the end of the dipstick using a clean, lint-
free cloth.


►  Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil level:
the correct level is between marks A (max) and
B (min).
Do not start the engine if the level is:
–

abo
ve mark A: contact a dealer or a qualified
workshop.
–

belo
w mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your dealer and qualified
workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of engine
failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.
►  Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►  Wait a few minutes before checking the level
again using the dipstick.
►  Top up the level if necessary.
►  After checking the level, carefully screw the
oil filler cap back on and replace the dipstick in
its tube.
Within 30 minutes of adding oil, the oil
level indication in the instrument panel
when the ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close to the
"MAX" mark. If not, check the brake pad
wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.

142
Practical information07
The check and top-up must only be done with the
engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the "MAX"
mark but should never exceed it.
If the level is close to or below the "MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi), and
in particular on the supply of AdBlue, refer to the
corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according to
your engine.
Otherwise, have them checked by a dealer or a
qualified workshop.
Only use products recommended by the
Manufacturer or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, the Manufacturer selects and
offers very specific products.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by a
dealer or by a qualified workshop.
Passenger compartment filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city
driving), change it twice as often, if necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate undesirable
odours.
Air filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city

Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).

Electric parking brake
This system does not require any routine
servicing. However, in case of an issue, 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 fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer

144
Practical information07
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
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
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 Diesel engines, the Manufacturer
has taken the decision to equip its vehicles with a
system that associates 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 15 litres.
Its capacity allows a driving range of
approximately 5,600 miles (9,000 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 blocked.
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 system
required by legislation prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a dealer or a
qualified workshop. After 680 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.
It is possible to obtain AdBlue
® from a dealer or a
qualified workshop as well as at 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.
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.
