Cause


Action/Observations






Low fuel level


fi xed,
accompanied
by an audible
signal and a
message on the
multifunction
screen. When it fi rst comes on there
remains approximately
7 litres of

fuel
in the tank. You must refuel as soon as possible to
avoid running out of fuel.
This warning lamp will come on every time
the ignition is switched on, until suffi cient
fuel has been added.
Fuel tank capacity: 60 litres.
Never continue to drive until you run out
of fuel, this could damage the emission
control and injection systems.





Foot on the
brake pedal


fi xed. The brake pedal is not
pressed. With the 6-speed electronic gearbox
system, you must press the brake pedal to
start the engine (lever in position N
).

fl ashing. The brake pedal is not
pressed. With the automatic gearbox, with the
engine running (lever in position P
), press
the brake pedal before releasing the
parking brake, to unlock the lever and
come out of position P
.
If you wish to release the parking brake
without pressing the brake pedal, this
warning lamp will remain on.
With the electronic gearbox
system, if you hold the vehicle
on an incline using the
accelerator for too long, the
clutch overheats. Use the brake pedal and/or the electric
parking brake.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer with additional lighting
and signalling.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to
a CITROËN dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions.

Driving advice


Distribution of loads


)
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 ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towed load must be reduced by 10 %
for every 1 000 metres of altitude.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce 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 STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


)
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.


Lighting


)
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

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.

QUESTIONANSWERSOLUTION
The stored stations donot function (no sound, 87.5 Mhz is displayed...).

An incorrect waveband is selected.
Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on whichthe stations are stored.

The traffi c announcement(TA) is displayed. I donot receive any traffi c information.
The radio station is not part of the regional traffi c information network.
Tune to a radio station which broadcasts traffi c information.

The quality of receptionof the radio station listened to graduallydeteriorates or the stored stations do not function(no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used by the station listened to or there is no transmitter in the geographical area through whichthe vehicle is travelling.
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode. This phenomenon is normal and does not indicate a failure of the audio equipment.
The aerial is absent or has been damaged (for example when goingthrough a car wash or into an underground car park).
Have the aerial checked by a CITROËN dealer.
Sound cut-outs of 1 to2 seconds in radio mode.During this brief sound cut-out, the RDS searches for any frequency permitting better reception of the station.
Deactivate the RDS function if the phenomenon is too frequent and always on the same route.

With the engine off, the audio equipment switches off after a few minutes of use.
When the engine is switched off, the audio equipment operating timedepends on the battery charge.
The switch-off is normal: the audio equipment switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the batterycharge.
The message "the audio system is overheated" appears on the display.
In order to protect the installation if the surrounding temperature is toohigh, the audio equipment switches to an automatic thermal protectionmode leading to a reduction of the volume or stopping of the playing of the CD.
Switch the audio system off for a few minutes toallow the system to cool.
