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.

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.
Access to the kit Composition of the kit
1.
12 V compressor, with built-in pressure
gauge.
2. Bottle of sealant, with built-in hose.
3. Speed limit sticker.

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.
Risk of electrocution
Xenon bulbs (D1S) must be replaced
in the dealer network or by a qualified
workshop.
