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.
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.



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.

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.


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

when connecting to the
USB port. The iPod is of a generation that is not compatible with the USB. Connect the iPod to the AUX Jack socket using a
suitable cable (not supplied).
The hard disk or device
is not recognised when
connecting to the USB
port. Some hard disks and devices need a power supply greater than is
provided by the audio system. Connect the device to the 230 V socket, the 12 V
socket or an external power supply.

Caution
: ensure that the device does not transmit
a voltage greater than 5 V (risk of destruction of
the system).

When streaming, the sound

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.
