Activation
)Turn the ring to the "AUTO"position. The activation of the function is accompanied
by the display of a message. When a low level of ambient li
ght is detected by a sunshine sensor, the number platelamps, sidelamps and dipped beam headlamps
are switched on automatically, without any
action on the par t of the driver. They can alsocome on if rain is detected, at the same time as
automatic operation of the windscreen wipers.

As soon as the brightness returns to asufficient level or after the windscreen wipers
are switched off, the lamps are switched off
automatically.
Deactivation
) Turn the ring to another position.Deactivation of the function is
accompanied by the display of a message.

Operating fault

In the event of a malfunction of the sunshine sensor, the lighting comes on, this warning lamp is displayed
In fog or snow, the sunshine sensor may detect sufficient light. In this case, thelighting will not come on automatically. Do not cover the sunshine sensor, coupled with the rain sensor andlocated in the centre of the windscreen behind the rear view mirror; the associated functions would no longer be controlled.

temperature or humidity), the presence of misting on the internal sur face of theglass of the headlamps and rear lampsis normal; it disappears after the lamps have been on for a few minutes.
The remote switching on o
f the lighting makesyour approach to the vehicle easier in poor
light. It is activated when the lighting control
is in the "AUTO" position and the level of light
detected by the sunshine sensor is low.



Switching off

The activation, deactivation and choice of
welcome lighting duration are done in the
" Driving assistance" menu then "Vehicle
settings". The exterior welcome li

The windscreen wipers operate automatically,
without any action on the par t of the driver, if
rain is detected (sensor behind the rear view mirror), adapting their speed to the intensity of
the rainfall.

Switching on
Switching off
The automatic rain sensitive windscreenwipers must be reactivated by pushing the control stalk downwards, if theignition has been off for more than oneminute. Brie
fly push the control stalk downwards.
A wiping cycle confirms that the instruction has been accepted.
This warning lamp comes on in theinstrument panel and a message is displayed. Brie
fly push the control stalk
downwards again, or place the control stalk in another position (Int, 1 or 2).

Special position of the
w
indscreen wipers

To maintain the effectiveness of the "flat-blade" type of wiper blades, it is advisable to:


- handle them with care,

- clean them regularly using soapywater,

- avoid using them to retain cardboard on the windscreen,

- replace them at the first signs of wear.
This position permits release o
f the windscreen
wiper blades.
It is used for cleaning or replacement of the blades. It can also be useful, in winter, todetach the blades from the windscreen.
Do not cover the rain sensor, linked with the sunshine sensor and located in the centre of the windscreen behind the rear view mirror.
Switch off the automatic rain sensitivewipers when using an automatic car wash.
In winter, it is advisable to wait until thewindscreen is completely clear of ice before activating the automatic rain sensitive wipers.

Operating fault
If a fault occurs with the automatic rain sensitive wipers, the wipers will operate in
intermittent mode.
Have it checked by CITROËN dealer or a
qualified workshop.

On switching off the ignition: )
any action on the wiper stalk in the minute
after switching off the ignition places the
blades vertically on the screen.
When the system is no longer powered - at least
one minute after switching off the ignition - it is
possible to move the arms manually. ) To park the blades again, switch on the
ignition and operate the wiper stalk.
Replacement of the arms must only be done by a CITRO

Safety








Ty r e u n d e r - i nfl ation detection
The system continuously monitors thepressures on the four tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever
y time the tyre pressures are adjusted or a wheel changed. The system triggers an aler t as soon as it
detects a drop in the inflation pressure of one
or more tyres.
The under-inflation detection system does not replace the vigilance or theresponsibility of the driver. This system does not avoid the need tocheck the tyre pressures (including the spare wheel) every month as well as before a long journey. Driving with under-inflated tyres impairsroad holding, extends braking distances and causes premature tyre wear,particularly under arduous condition(high loading, high speed, long journey). S
ystem which automatically checks the pressure of the tyres while driving.

The inflation pressures defined for your vehicle can be found on the tyrepressure label (see the "Identificationmarkings" section). Tyre pressures should be checkedwhen the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderatespeeds). Other wise, add 0.3 bar to the pressures shown on the label.

Driving with under-inflated tyresincreases fuel consumption.

Driving advice


Distribution of loads
)Distribute the load in the trailer so that theheaviest 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. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.

Side wind
)Take into account the increased sensitivity
to side wind.
Cooling
To w i ng a trailer on a slope increases the
temperature of the coolant.
As the fan is electricall
y controlled, its cooling capacity is not dependent on the engine speed.
)
To lower the engine speed, reduce your speed.
The maximum towed load on a long incline
depends on the
gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
) If the warning lamp and the
STOPwarning lamp come on, stop the vehicle and switch off
the engine as soon as possible.



Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

Tyres
)
Check the tyre pressures of the towingvehicle and of the trailer, obser ving the
recommended pressures.



Lighting
)
Check the electrical lighting and signalling on the trailer.

R
efer to the "Technical data" section for detailsof the weights and towed loads which apply to your vehicle.


The rear parking sensors will be
deactivated automatically if a genuineCITROËN towbar is used.

When not towing a trailer, remove thequickly-detachable tow ball beforedriving.
