windscreen wipers operate for a fixed
period.
It operates only when the headlamps are off or
the vehicle is stationary.
Low screenwash / headlamp
wash fluid level
On vehicle fitted with headlamp washers, the
low level of this fluid is indicated by gauge in
the reservoir filler neck under the bonnet.
Checking and topping up this fluid can should
be done with the engine off.
The level of this fluid should be
checked regularly, particularly during
w i n t e r.
Refer to the "Checks - Screenwash / headlamp
wash level" section for the procedure on
checking the level.
Headlamp wash
Associated with the windscreen wash, the
headlamp washers operate with the vehicle
moving, when the dipped or main beam
headlamps are on .
To reduce the consumption of the fluid
by the headlamp washers, they operate
only with every seventh use of the
screenwash or every 25 miles (40 km)
during a given journey.

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 per formance. 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

T
o 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

I
f 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.
Ty r e s
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.
