Lighting controls
System for selection and control of the various
front and rear lamps providing the vehicle's
lighting.
Main lighting
The various front and rear lamps of the vehicle
are designed to adapt the driver's visibility
progressively according to weather conditions:
-
s
idelamps, to be seen,
-

d
ipped beam headlamps to see without
dazzling other drivers,
-

m
ain beam headlamps to see clearly when
the road is clear.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal sur face of the
glass of the headlamps and rear lamps is
normal; it disappears after the lamps have
been on for a few minutes.
Additional lighting
Other lamps are provided to meet the
requirements of particular driving conditions:
-

the volume of the audible signal will
increase if the speed is above 37 mph
(60


km/h).
Three flashes
F Press briefly upwards or downwards, without going beyond the point of
resistance; the direction indicators will flash
3 times. On versions fitted with LED direction indicators,
the line of LEDs is illuminated sequentially.
The brightness of the daytime runnning lamps
is reduced during sequential operation of the
direction indicators.
Daytime running lamps
Daytime lighting which comes on automatically
when the engine is started making the vehicle

Direction indicators (flashing)
Side markers for the vehicle by illumination of
the sidelamps on the traffic side only.
F Depending on version, within one minute of
switching off the ignition, operate the lighting
control stalk up or down depending on the
traffic side (for example: when parking on
the left; lighting control stalk upwards; the
right-hand sidelamps come on).
This is confirmed by an audible signal and
illumination of the corresponding direction
indicator warning lamp in the instrument panel.
To switch off the parking lamps, return the
lighting control stalk to the central position.
Manual guide-me-home
lighting
The temporary illumination of the dipped beam
headlamps after the vehicle's ignition has been
switched off makes the driver's exit easier
when the light is poor.
Switching on
F With the ignition off, "flash" the headlamps using the lighting control stalk.

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.

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.

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

configuration menu.
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

I
n the minute following ignition switch-off,
any operation of the wiper control stalk will
position the wiper blades vertically.

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.
