Advice on driving 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 towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
For more information on Petrol weights or
Diesel weights and in particular the towed
loads which apply to your vehicle, refer to the
corresponding section.
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 slope
depends on the gradient and the exterior
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
To limit heat build-up in the brakes, use of the
engine brake 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 lighting and signalling on the trailer and the adjustment of the vehicle's
headlamps.
For more information on Headlamp
adjustment , refer to the corresponding
section.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
The rear parking sensors will be
deactivated automatically when a
genuine CITROËN towbar is used.

Changing a bulb
For bulbs that have alignment lugs
(H1, H7...) ensure that they are
fitted correctly for the best lighting
performance.
The headlamps have polycarbonate
lenses with a protective coating:
F

d

o not clean them using a dr y
or abrasive cloth, nor with a
detergent or solvent product,
F

u

se a sponge and soapy water,
F

w

hen using a high pressure washer
on persistent marks, do not keep
the lance directed towards the
lamps or their edges for too long,
so as not to damage their protective
coating and seals.
F

D

o not touch the bulb directly with
your fingers, use lint-free cloths.
Changing a bulb should only be done
after the headlamp has been switched
off for several minutes (risk of serious
burns).
It is imperative to use only
anti-ultraviolet (UV) type bulbs in order
not to damage the headlamp.
Always replace a failed bulb with a
new bulb with the same type and
specification.

Replacement of the xenon bulbs
(D1S-35W) must be carried out by
a CITROËN dealer or a qualified
workshop.
