fter checking the level, carefully refit the oil
filler cap and the dipstick in its tube.
After topping up the oil, the ignition-triggered oil
level indicator in the instrument panel does not
provide a valid information during 30 minutes.
Engine oil change
Refer to the manufacturer's service schedule
for inter val details for this operation.
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 coolant
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.
Power steering fluid level
The fluid level should be close to
the "MA X" mark. Verify this, with the
engine off, by reading the level on
the filler neck.
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.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off the
engine before carrying out any work.
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.
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 brake fluid must conform to the
manufacturer's recommendations.

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule for details of the
replacement intervals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them 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
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

t
emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. 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.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 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.

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.
