Limit the causes of excess
consumption
At the end of winter, remove snow tyres and
refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a
BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit a member
of the dealer network or a qualified workshop
to make your vehicle's level of nitrogen oxides
emissions compliant to the standard.
When filling the tank, do not continue after the
3
rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after the first 1,900
miles (3,000 kilometres)
that you will see the fuel consumption settle
down to a
consistent average.
Spread loads throughout the vehicle; place
the heaviest items in the bottom of the boot,
as close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
Do not forget the spare wheel and the tyres on
any trailer or caravan.

Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBD)It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by
a
reduction in the resistance of the pedal and
an increase in the effectiveness of the braking.
When lit up continuously, this
warning lamp indicates a
fault with
the ABS.
The vehicle retains conventional braking. Drive
carefully at moderate speed.
If these warning lamps come on,
accompanied by an audible signal
and a
message, this indicates a fault
with the electronic brake force
distribution (EBFD).
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS system may
be indicated by slight vibration felt at the
brake pedal. In case of emergency braking, press
ver y hard without releasing the
pressure at all.

Activation
These systems are activated automatically
every time the vehicle is started.
They come into operation in the event of
a
problem with grip or trajectory.
This is indicated by flashing of this
warning lamp in the instrument
panel.
Deactivation
In extremely severe conditions (deep snow,
mud, etc.), if you are unable to move off, it
may be useful to temporarily deactivate these
systems so that the wheels can spin and allow
the vehicle to regain grip.
You must stop as soon as it is safe to do so.
In both cases, have the system checked in the
dealer network or by a

qualified workshop as
soon as possible.

F Press this button.
If the indicator lamp in the button comes on,
this indicates that the systems are deactivated.
Reactivation
These systems are reactivated automatically
every time the ignition is switched off, or
from 30 mph (50 km/h), except for the 1.6 l
petrol and (THP 165, THP 155, THP 150) and
PERFORMANCE engines.

Operating fault
Illumination of this warning lamp
and the indicator lamp in the button,
accompanied by an audible signal
and a
message, indicate a fault with
these systems.
Have them checked by an
authorised dealer or by a
qualified
workshop. ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations, not
only about the wheels (tyres and rims),
braking and electronic components but
also the assembly and repair procedures
used in the dealer network.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Seat belts
Front seat belts
The front seat belts are fitted with
a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a
front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of
the seat belt on the passenger's chest, thus
improving their protection.
Fastening
F Pull the strap then insert the tongue in the buckle.

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.

If the engine is in STOP mode, it restarts
immediately.
The Stop & Start system is reactivated
automatically every time the ignition is switched
on.
Press the button to deactivate the system.
Deactivation is confirmed by illumination of the
indicator lamp in the button and the display of
a

message.
Pressing this button again reactivates the
function.
The indicator lamp goes off and a
message is
displayed.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid any risk of injury resulting from an
automatic change to START mode. Driving on flooded roads
Before driving in a
flooded area, it is
strongly recommended that you deactivate
the Stop & Start system.
For more information on Driving advice ,
particularly on flooded roads, refer to the
corresponding section.
Operating fault
In the event of a fault with the system, the
b utton in the ECO OFF switch flashes for a few
moments, then remains on.
Have it checked by an authorised dealer or by
a


qualified workshop.
If a
fault occurs in STOP mode, the engine
may stall. All of the instrument panel warning
lamps come on. It is then necessary to switch
the ignition off and to restart the engine using
t h e key. The Stop & Start system requires a
12 V
battery of specific technology and
specification.
All work on this type of battery must only
be carried out in the dealer network or by
a

qualified workshop.
For more information on the 12 V batter y
,
refer to the corresponding section.Tyre under-inflation
d
etection
System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressure in all four
tyres, as soon as the vehicle is moving.
It compares the information given by the
wheel speed sensors with reference values,
which must be reinitialised after ever y tyre
pressure adjustment or wheel change .
The system triggers an alert as soon as it
detects a
drop in the pressure of one or more
tyres.

The tyre under-inflation detection system
does not replace the need for vigilance on
the part of the driver.
This system still requires you to check the
tyre inflation pressure (including the spare
wheel) every month as well as before
a

long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings , refer to the
corresponding section. Tyre pressures should be checked when
the tyres are "cold" (vehicle stopped for
1
hour or after a journey of less than
6
miles (10 km) at moderate speeds).
Other wise (when hot), add 0.3
bar to the
pressures shown on the label.

cold. If it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The warning remains active until the
system is reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the tyre
pressure label.
The under-inflation detection system
does not give a
warning if a pressure is
incorrect at the time of reinitialisation.
