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 exceeding it.
Air 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.


Side wind




Take into account the increased sensitivity
to side 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.



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 STOP

warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.

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



Braking

Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.


Ty r e s




Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the
recommended pressures.



Lighting




Check the electrical lighting and signalling
on the trailer.

Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.

SOLUTION

In "Random all" play,
not all of the tracks are
played. In "Random all" play, the system can only take into account up to
999 tracks.
With the engine off, the
audio system switches
off after a few minutes
of use. When the engine is switched off, the audio system operating time
depends on the battery charge.
The switch-off is normal: the audio system switches to economy mode
and switches off to prevent discharging the vehicle's battery. Start the vehicle's engine to increase the battery
charge.
The message "the audio
system is overheated"
appears on the display. In order to protect the installation if the surrounding temperature is too
high, the audio system switches to an automatic thermal protection mode
leading to a reduction of the volume or stopping of the playing of the CD. Switch the audio system off for a few minutes to
allow the system to cool.
