When towing
distribution of loads
F
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 performance. Above
1 000 metres, the maximum towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
Side wind
F
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.
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.
F
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 braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Tyres
F
Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
F
Check the electrical lighting and signalling
on the trailer and the hadlamp beam height
of your vehicle.
For more information on adjusting the
headlamp beam height, refer to the
corresponding section.
For more information on weights (and the
towed loads which apply to your vehicle) refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.
