Airbags
General information
This system contributes towards improving the
safety of passengers (with the exception of the
rear centre passenger) in the event of violent
collisions. The airbags supplement the action
of the seat belts fitted with force limiters (all
except the centre rear passenger belt).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-

i
n the event of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the passengers
(with the exception of the rear centre
passenger); immediately after the impact,
the airbags deflate rapidly so that they
do not hinder visibility or the exit of the
passengers,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations. The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once. If
a
second impact occurs (during the same
or a subsequent accident), the airbag will
not be deployed again.
Impact detection zones
A. Front impact zone.
B. Side impact zone. The deployment of an airbag is
accompanied by a
slight emission of
smoke and a noise, due to the detonation
of the pyrotechnic charge incorporated in
the system.
This smoke is not harmful, but sensitive
individuals may experience slight irritation.
The detonation noise associated with the
deployment of an airbag may result in
a slight loss of hearing for a short time.
Front airbags
System which protects the driver and front
passenger in the event of a
serious front impact
in order to limit the risk of injury to the head and
chest.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a
long journey, a break every two hours is
strongly recommended.
In bad weather, drive smoothly, anticipate the
need to brake and increase the distance from
other vehicles.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a
risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4
minutes before driving.
Important!
Never drive with the parking brake
applied – Risk of overheating and damage
to the braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, dead leaves, etc.) – Risk of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle. If you are obliged to drive through water:
-

c
heck that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
-
d
eactivate the Stop & Start function,
-
d
rive as slowly as possible without stalling.
In all cases, do not exceed a speed of
6 mph (10 km/h),
-
d
o not stop and do not turn off the engine.
On leaving the flooded road, and as soon as it
is safe to do so, brake lightly several times to
dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact the dealer network or a qualified
workshop.

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude.
Please respect the maximum towable
weights.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 600


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a
genuine
DS
AUTOMOBILES towbar is used.
If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1
to 2 minutes after the vehicle
comes to a
stop, to facilitate its cooling.

F Pull the selector towards the – sign to change down a gear.
It is only possible to change from one gear to
another if the vehicle speed and engine speed
permit; otherwise, the gearbox will operate
temporarily in automatic mode.
Invalid value during manual
operation
This symbol is displayed if a gear
i s not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to keep
the vehicle stationary.
If the selector is not in position P , when the
driver's door is opened or approximately
45
seconds after the ignition is switched
off, a warning message appears on the
screen.

engaged appear in succession in
the instrument panel.
If the engine speed is too low or too high, the
gear selected flashes for a
few seconds, then
the actual gear engaged is displayed.
It is possible to change from position D
(automatic) to position M (manual) at any time.
When the vehicle is stationary or moving
very slowly, the gearbox selects gear
M1


automatically.
The sport and snow programmes are inactive
in manual operation. When the ignition is on, the lighting
of this warning lamp, associated with
an audible signal and a
message
on the screen, indicates a
gearbox
fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd gear. You may then
feel a

substantial jolt when changing from P to
R and from N to R . This jolt will not cause any
damage to the gearbox. Do not exceed 60
mph (100 km/h), local speed
restrictions permitting.
Contact a dealer approved by
DS AUTOMOBILES or a qualified workshop as
soon as possible.
There is a risk of damage to the gearbox:
-
i
f you press the accelerator and brake
pedals at the same time,
-
i
f you force the selector from position P
to another position when the battery is
flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake.
Automatic gearbox (EAT6)
Six speed automatic gearbox which offers
a choice between the comfort of fully automatic
operation or manual gear changing.
Two driving modes are available:
-

Gear efficiency indicator
System which reduces fuel consumption by
advising the driver when to change up.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
It is only possible to change from one gear to
another if the vehicle speed and engine speed
permit; otherwise, the gearbox will operate
temporarily in automatic mode.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd gear. You may then
feel a

substantial jolt when changing from P to

With an electronic or automatic gearbox,
the system is only active in manual mode.
On BlueHDi Diesel versions with manual
gearbox, in certain driving conditions the
system may suggest changing into neutral so
that the engine can go into standby (STOP
mode of Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal.
-

T
he system may suggest that you engage
a


higher gear. The system adapts its gear change
recommendation according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear.
-
enga

ging a

lower gear.
On vehicle fitted with a
manual gearbox,
the arrow may be accompanied by the
recommended gear.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
The information appears in the instrument
panel in the form of an arrow.
Hill start assist
This system briefly keeps your vehicle
stationary (for approximately 2 seconds) when
making a
hill start, while you transfer your foot
from the brake pedal to the accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver's door is closed.
The hill start assist system cannot be
deactivated.
Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up constantly on
the instrument panel.

Operating fault
If a fault occurs with the system,
t hese warning lamps come on.
Contact the dealer network or
a
qualified workshop to have the
system checked.
Stop & Start
The Stop & Start system puts the engine
temporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
Going into engine STOP
mode
The " ECO" warning lamp comes
on in the instrument panel and the
engine goes into standby:
-

w

ith a

manual gearbox , at speeds below
12

mph (20 km/h) (depending on version),
when you place the gear lever in neutral and
you release the clutch pedal.
-

w

ith a
5-speed or 6-speed electronic
gearbox , vehicle stationary or at speeds
below 5
mph (8 km/h) (depending on
version), when you press the brake pedal or
place the gear selector into position N .
-

w

ith an automatic gearbox , vehicle
stationary, when you press the brake pedal
or put the gear selector in position N .
A time counter adds up the time
periods spent in STOP mode
during a
journey. It resets every
time the ignition is switched on
using the key.
Uphill, with the vehicle stationar y, the
vehicle is held for a shor t time when you
release the brake pedal.
With a

manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in D or M .

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).
