Manual parking brake
If excessive travel or a loss of
effectiveness 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.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked in the dealer network or by
a qualified workshop.
For more information on the Electric
parking brake , refer to the corresponding
section.
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 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 oxides of nitrogen (NOx) into nitrogen and
water, which are harmless to health and the
environment.
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.
07
Practical information

184
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 around 12,500 miles
(20,000

km), it will be necessary to top up the
AdBlue
®. Once the AdBlue
® tank is empty, a system
r
equired by regulations prevents starting
of the engine.
If the SCR

system is defective, the level of
emissions from your vehicle will no longer
meet the Euro 6 standard: your vehicle
becomes polluting.
In the event of a confirmed fault with the
SCR system, you must go to the dealer
network or a qualified workshop as soon
as possible: after a running distance of
685 miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
For more information on the Warning
lamps and the associated alerts, refer to
the corresponding section.
The AdBlue® is contained in a special tank
with 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).
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.
Topping up with AdBlue®
Filling the AdBlue® tank is an operation
included in every routine ser vice on your
vehicle by the dealer network or a qualified
workshop.
Nevertheless, given the capacity of the tank,
it may be necessary to top up the AdBlue
®
between ser vices, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can go to a member of the dealer network
or a qualified workshop.
If you envisage topping up yourself, please
read the following recommendations and
warnings carefully.
Precautions for use
AdBlue® is a urea-based solution. This fluid
is non-flammable, colourless and odourless
(stored 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. If a burning sensation or irritation
persists, get medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
07
Practical information

185
Keep AdBlue® out of the reach of children,
in its original container or bottle.
Never transfer AdBlue
® to another
container: it would lose its purity.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank. Containers or bottles are available from the
dealer network or a qualified workshop.
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Recommendations on storage
AdBlue® freezes below around -11°C and
deteriorates above 25°C. It is recommended
that bottles or containers be stored in a cool
place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never store bottles or containers of
AdBlue
® in your vehicle.
Procedure
Before topping up, ensure that the vehicle is
parked on a flat and level sur face.
In wintry conditions, ensure that the
temperature of the vehicle is above -11°C.
Otherwise the AdBlue
® may be frozen and F

® fluid that meets the
ISO
22241 standard. so cannot be poured into its tank. Park your
vehicle in a warmer area for a few hours to
allow the top-up to be carried out.

Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Matt finish
If your vehicle is coated with a clear, matt
varnish, it is essential that you take the
following instructions into account to avoid
damaging the paint, due to an inappropriate
treatment. These instructions are also valid for
the alloy wheels coated in a clear, matt varnish.
Textured paint
The textured paint reacts to light with variations
of appearance and finish that emphasise the
car's lines and form. This paint coating has
particles that remain visible and create a
unique satin relief effect. Its lightly granulated
texture gives it a surprising feel.
07
Practical information

187
Observe the following recommendations to
avoid damaging the paint finish:
-
N
ever clean the vehicle without water.
-

N
ever clean your vehicle in an
automatic roller-brush car wash.
-

N
ever select the programme with hot
wax finish.
-

N
ever use a high pressure jet washer
fitted with a brush as this may scratch
the paint sur face.
-

N
ever polish the body or the alloy
wheels. This makes the paint bright.
-

D
o not use paint restorers, abrasive
or polishing products, or bright paint
preser vers (wax polish, for example).
These products are only suitable for
bright finishes. Using them on vehicles
finished with matt paint seriously
damages the sur face finish of the
vehicle, resulting in particular in the
appearance of irreversible bright or
stained areas. It is always preferable to have paint
repairs carried out in the dealer network or
by a qualified workshop.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty Guide for information on all the
special precautions to observe.
In addition:
-

C

hoose a high pressure wash, or at least a
high-flow water jet.
-
R

inse the vehicle with demineralised water.
-

G

ently wipe the body with a clean
microfibre cloth.
-

C

arefully wipe off any fuel spilt on the body
using a soft cloth, then allow to dry.
-
C
lean off minor marks (for example, finger
marks), using the maintenance product
recommended by DS AUTOMOBILES.

Temporary puncture
repair kit
This kit comprises a compressor and a sealant
cartridge.
It allows the temporary repair of a tyre.
You are then able to go to the nearest garage.
It is designed to repair most punctures
which could affect the tyre, located on the
tyre tread or shoulder.
Its compressor can be used to check and
adjust the pressure of the tyre.
Tyre under-inflation detection
If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the system
is reinitialised by a dealer or a qualified
workshop.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair. Only
the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
