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 exterior
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 headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

Driving

234
Before each use
Check that the towball is correctly fitted by verifying the following points:
- t he towball is correctly locked in place (position A ),
-

t
he security key lock is on and the key removed; the locking wheel can no longer be
operated,
-

t
he towball must no longer move at all in its carrier; try to shake it by hand.
During use
Never unlock the device when a trailer or load carrier is fitted to the towball.
Never exceed the maximum authorised weight for the vehicle plus trailer (Gross Train
Weight - GTW).
Before driving, check the adjustment of the headlamp beam height.
For more information on Adjusting the headlamps , refer to the corresponding section.
After use
For journeys made without a trailer or load carrier, the trailer harness socket must be folded
away, the towball removed and
the blanking plug inserted in the carrier. This measure
applies particularly if the towball could hinder visibility of the number plate or lighting.
Fitting the towball
Remove the protective plug from the carrier
and check the condition of the fixing system.
If necessary, clean the carrier with a brush or
clean cloth.
Take the towball from the storage bag.
Remove the protective cover from the ball
and
the protective cap from the locking wheel.
Stow the plug, cover and cap in the
storage
bag.
Check that the towball is unlocked (position B ).
If not, insert the key in the lock and turn the key
anti-clockwise to unlock the mechanism.
