Operation
- the braking assistance systems (ABS, EBFD, EBA) are not faulty.
-

t
he trajectory control systems (ASR, DSC)
are not deactivated or faulty,
-

t
he vehicle is not making a sharp turn,
-

t
he system has not triggered in the last ten
seconds.
When your vehicle is too close to or
approaches the vehicle ahead too quickly, the
system automatically applies the brakes to
avoid a


collision.
You are then warned by the display of
a


message.
The brake lamps of your vehicle are lit to warn
other users.
The collision can be avoided if the speed
difference between your vehicle and the one
ahead is not more than 9
mph (15 km/h).
Above this threshold, the system will do
what is possible to avoid or reduce the
accident by lowering the speed of impact.
The automatic braking can lead to the complete
stop of the vehicle if the situation requires it. In this case, the vehicle is held stationary
temporarily (for about 1.5
seconds) to allow
the driver to take back control by pressing the
brake pedal.
Unless the driver depresses the clutch
pedal quickly enough during automatic
braking, triggering of the system may
cause the engine to stall.
During automatic braking, the driver can
always obtain a
higher rate of deceleration
than that controlled by the system, by
pressing firmly on the brake pedal.
After an impact, the system is
automatically put out of ser vice: it no
longer operates.
You must go to a
member of the dealer
network or a
qualified workshop to have
the system made operational again.Deactivation
The system is deactivated in the vehicle
configuration menu, accessible with the ignition on.
Its state is memorised when the ignition is switched

Energy economy mode
System which manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can still
use functions such as the audio equipment,
windscreen wipers, dipped beam headlamps,
courtesy lamps, etc. for a
maximum combined
period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to economy mode and the
active functions are put on standby.
Exiting the mode

the engine and let it run briefly. If the telephone is being used at the same
time, it will be interrupted after 10
minutes.The engine will not start if the battery is
discharged.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by the dealer
network or a
qualified workshop.
The liquids must comply with the
manufacturer's recommendations 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
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Return used oil to the dealer network or
a
qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick. To ensure that the reading is correct, your
vehicle must be parked on a
level sur face
with the engine stopped for more than
30

minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). We recommend that
you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
Checking using the dipstick

I

f the level is below the MIN mark, you must
top up the engine oil.
Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view. After topping up the oil, the check
per formed by the oil level indicator in
the instrument panel when the ignition
is switched on is not valid during the
30
minutes after topping up.
Engine oil change
In order to maintain the reliability of the engine
and emission control system, never use
additives in the engine oil.
Brake fluid level
The brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.
Changing the fl
uid
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
This fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
To ensure that the reading is correct, your
vehicle must be parked on a
level sur face with
the engine cool.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a
risk of serious
damage to your engine.
When the engine is warm, the temperature of
the coolant is regulated by the fan.

Oil grade
Before topping up the oil or changing the oil,
check that the oil is the correct grade for your
engine and conforms to the manufacturer's
recommendations.
In addition, with the engine hot and as the
cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.

The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Screenwash fluid level
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) . To avoid the risk of scalding when you need to
top up in an emergency, place 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 the level.
Diesel fuel additive level
(Diesel with particle filter)
The additive tank minimum level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a
message that
the particle filter additive level is
too low.
Topping up
This additive must be topped up without
delay by a member of the dealer network or
a


qualified workshop.
AdBlue level
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue
® and the SCR
system, and in particular topping it up, 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 the dealer
network or a
qualified workshop.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened and
that the connections are clean.
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 in the dealer network or a
qualified
workshop.
When carrying out any operation on the 12
V
battery, refer to the corresponding section for
details of the precautions to be taken before
starting work.
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).

Air filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary.
Passenger compartment filter
Depending on the environment
(e.g. dusty atmosphere) and the
use of the vehicle (e.g. city driving),
replace it twice as often if
necessary.
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
Oil filter
Replace the oil filter each time the
engine oil is changed.
Particle filter (Diesel)
The start of saturation of the particle
filter is indicated by the temporary
illumination of this warning lamp
accompanied by the display of
a


message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at
least 40

mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a

low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
On a

new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
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 on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Parking brake
If excessive travel or a loss of
e ffectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked in the dealer
network or by a
qualified workshop.

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.
Brake disc/drum wear
For information on checking brake
disc wear, contact the dealer
network or a
qualified workshop. Only use products recommended by
DS
AUTOMOBILES or products of
equivalent quality and specification.
In order to optimise the operation of
components as important as those in
the braking system, DS AUTOMOBILES
selects and offers very specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
AdBlue® (BlueHDi
engines)
To respect the environment and ensure
compliance with the Euro 6
standard,
without adversely affecting the performance
or fuel consumption of diesel engines,
DS
AUTOMOBILES 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 oxides of nitrogen (NOx) into nitrogen and
water, which are harmless to health and the
environment.
During each scheduled ser vice of your vehicle
in the dealer network or a

qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated distance travelled between
two ser vices is greater than 12,500
miles
(20,000

km), it will be necessary to top up the
AdBlue
®.
The AdBlue
® is contained in a special tank
w
ith a
capacity of around 17 litres: its capacity
offers a

driving range of around 12,500 miles
(20,000

km) before triggering an alert system
that warns you when you can drive for a
further
1,500

miles (2,400 km).
