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.
Anti-slip regulation (ASR)/

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.
F

P
ress this button again to reactivate them
manually.
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.

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.

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.

are not deactivated or faulty,
-

t
he vehicle is not making a sharp turn,
-

t
he system has not triggered in the last ten
seconds.
When your vehicle is too close to or
approaches the vehicle ahead too quickly, the
system automatically applies the brakes to
avoid a


collision.
You are then warned by the display of
a


message.
The brake lamps of your vehicle are lit to warn
other users.
The collision can be avoided if the speed
difference between your vehicle and the one
ahead is not more than 9
mph (15 km/h).
Above this threshold, the system will do
what is possible to avoid or reduce the
accident by lowering the speed of impact.
The automatic braking can lead to the complete
stop of the vehicle if the situation requires it. In this case, the vehicle is held stationary
temporarily (for about 1.5
seconds) to allow
the driver to take back control by pressing the
brake pedal.
Unless the driver depresses the clutch
pedal quickly enough during automatic
braking, triggering of the system may
cause the engine to stall.
During automatic braking, the driver can
always obtain a
higher rate of deceleration
than that controlled by the system, by
pressing firmly on the brake pedal.
After an impact, the system is
automatically put out of ser vice: it no
longer operates.
You must go to a
member of the dealer
network or a
qualified workshop to have
the system made operational again.Deactivation

use functions such as the audio equipment,
windscreen wipers, dipped beam headlamps,
courtesy lamps, etc. for a
maximum combined
period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to economy mode and the
active functions are put on standby.

Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by the dealer
network or a
qualified workshop.
The liquids must comply with the
manufacturer's recommendations and with
the vehicle's engine. Take care when working under the bonnet,
as certain areas of the engine may be
extremely hot (risk of burns) and the
cooling fan could start at any time (even
with the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Return used oil to the dealer network or
a
qualified workshop and dispose of it in
the containers reser ved for this purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick. To ensure that the reading is correct, your
vehicle must be parked on a
level sur face
with the engine stopped for more than
30

minutes.
It is normal to top up the oil level between two
ser vices (or oil changes). We recommend that
you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
