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.

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.

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.

Changing a bulb
The headlamps have polycarbonate
lenses with a protective coating:
F
d
o not clean them using a dr y or
abrasive cloth, nor with a detergent
or solvent product,
F

u
se a sponge and soapy water or a pH
neutral product,
F

w
hen using a high pressure washer
on persistent marks, do not keep the
lance directed towards the lamps or
their edges for too long, so as not to
damage their protective coating and
seals.
Changing a bulb must only be done with
the ignition off and after the headlamp has
been switched off for several minutes –
Risk of serious burns!
F

D
o not touch the bulb directly with your
fingers, use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new
bulb with the same type and specification. In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
Light-emitting diodes (LED)
For the replacement of this type of lamp,
contact the dealer network or a qualified
workshop.
A LED (light-emitting diode) replacement
kit is available from the dealer network.
For bulbs with lugs, type H1, H7... take
care to position them correctly to ensure
the best lighting.
