Warning/indicator lampis on Cause Action / Observations
STOP fixed, associated with
another warning lamp. It is associated with the braking
system or the engine coolant
temperature. Stop as soon as it is safe to do so.
Park, switch off the ignition and call a CITROËN
dealer or a qualified workshop.
Service temporarily,
accompanied by
a message. One or more minor faults for which
there is no specific warning lamp
have been detected. Identify the cause of the fault using the message
displayed in the screen.
You can deal with some problems yourself, such as a
door open or the start of saturation of the particle filter
(as soon as the traffic conditions allow, regenerate
the filter by driving at a speed of at least 40 mph
(60 km/h), until the warning lamp goes off).
For any other problems, such as a fault with the tyre
under inflation detection system, contact a CITROËN
dealer or a qualified workshop.

Towing a trailer
Your vehicle is primarily designed for transporting people and luggage, but it may also be used for towing a trailer.
Side wind
F Take into account the increased sensitivity
to side wind.
Driving advice
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 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.
We recommend the use of genuine
CITR
oËn towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
and that the fitting of the towbar is
entrusted to a CITR oËn dealer or a
qualified workshop.
If the towbar is not fitted by a
CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care.
Distribution of loads
F d istribute 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.
a ir density decreases with altitude, thus
reducing engine per formance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
F If the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
