Automatic illumination of
headlamps
When a low level of ambient light is detected
by a sunshine sensor, the number plate
lamps,

sidelamps and dipped beam headlamps
are switched on automatically, without any
action on the part of the driver. They can also
come on if rain is detected, at the same time as
automatic operation of the windscreen wipers.
As soon as the brightness returns to a
sufficient level or after the windscreen wipers
are switched off, the lamps are switched off
automatically.

Automatic adjustment
of xenon and full-LED
headlamps
The initial setting is position " 0".
This system adjusts the height of the xenon
headlamp beams automatically and when
stationary, according to the vehicle's load, so as
to avoid causing a nuisance to other road users.
If a malfunction occurs, this warning
lamp is displayed in the instrument
panel, accompanied by an audible
signal and a message in the screen.
The system then places your headlamps in the
lowest position. In the event of a fault, do not touch the
xenon bulbs.
Have them checked in the dealer network
or by a qualified workshop.

Directional lighting
When the dipped or main beams are on, this
function allows the light beam to better follow
the road.
The use of this function, coupled only with the
xenon headlamps and the cornering lighting,
significantly improves the quality of your
lighting in bends.
Without directional lighting With directional lighting
The system does not operate:
-

This function is activated by default.
The state of the function stays in
memory when switching off the
ignition.
Operating fault
If a fault occurs, this warning lamp
flashes in the instrument panel,
accompanied by a message in the
screen.
Contact the dealer network or a
qualified workshop.
Cornering lighting
With dipped or main beams, this system
makes use of the beam from a front foglamp
to illuminate the inside of a bend, when the
vehicle speed is below 25 mph (approximately
40 km/h) (urban driving, winding road,
intersections, parking manoeuvres...).

Malfunction
If a fault occurs with the automatic rain sensitive
wipers, the wipers will operate in intermittent mode.
Contact the dealer network or a qualified workshop.
Do not cover the rain sensor, linked with
the sunshine sensor and located in the top
centre of the windscreen, behind the rear
view mirror.
When using an automatic car wash, switch
off the automatic rain sensitive wipers.
In winter, it is advisable to wait until the
windscreen is completely clear of ice before
activating the automatic rain sensitive wipers.
Windscreen and headlamp
wash
Front screenwashHeadlamp wash
To reduce the fluid consumption of the
headlamp wash, it operates only with
every seventh use of the screenwash or
every 25 miles (40 km) during a given
j o u r n ey.
Low screenwash/headlamp wash
fluid
level
Checking and topping up this fluid should be
done with the engine off.
The fluid level should be checked
regularly, particularly during winter.
For more information on Checking levels and,
in particular, the screenwash/headlamp wash,
refer to the corresponding section.
Special position of the
windscreen wipers
This position permits release of the windscreen
wiper blades.
It is used for cleaning or replacement of the
wiper blades. It can also be useful, in winter, to
release the wiper blades from the windscreen.
F

P

ull the windscreen wash control towards
you. The windscreen wash and then the
wipers come on for a preset time.
They operate by themselves when the dipped
and main beam headlamps are off or when the
vehicle is stationary. Associated with the screenwash, the headlamp
wash operates when the vehicle is moving and
the dipped or main beam headlamps are on
.
On vehicles fitted with headlamp washers, the
low level of this fluid is indicated by a gauge
located in the reser voir filler neck under the
bonnet. F

In case of towing
Driving with a trailer places greater
demands 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.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
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.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
temperature 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 towed load on a long 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.
Braking
Towing a trailer increases the braking distance.
To 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
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.

During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the gross train weight
(GTW) for the vehicle.
Before setting off, check the adjustment of
the headlamp beam height.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
After use
For journeys made without a trailer or
load carrier, the trailer socket must be
folded away, the towball removed and the
protective plug inserted in the carrier. This
measure applies particularly if the towball
could hinder visibility of the number plate
or lighting.Fitting the towball

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy saving mode
System that manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can
still 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 the energy saving
mode and the active functions are put on
st a n d by.If the telephone was operated via
the touch screen at that moment, the
connection would be interrupted after
10


minutes.
Exiting the mode
These functions will be automatically restored
the next time the vehicle is used.
F
I
n order to restore the use of these functions
immediately, start the engine and let it run
for a few minutes.
The time available to you will then be double
the period for which the engine is left running.
However, this period will always be between
five and thirty minutes.
The engine will not start if the battery is
discharged.
