When towing
Distribution of loads
F Distribute the load in the trailer so that the h
eaviest items are as close as possible to
t
he axle and the nose weight approaches
t
he maximum permitted without
e
xceeding it.
Air
density decreases with altitude, thus
r
educing engine per formance. Above
1 0
00 metres, the maximum towed load must
b
e reduced by 10 % for every 1 000 metres of
al
titude.
For
more information on weights (and the
t
owed loads which apply to your vehicle) refer
t
o the corresponding section.
Side wind
F Take into account the increased sensitivity t
o side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant.
As
the fan is electrically controlled, its cooling
c
apacity is not dependent on the engine speed.
F
T
o lower the engine speed, reduce your
s
peed.
The
maximum towed load on a long incline
d
epends on the gradient and the ambient
t
emperature.
In
all cases, keep a check on the coolant
t
emperature. F
I
f the warning lamp and the
S
TOP
warning lamp come on,
s
top the vehicle and switch off
t
he engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
e
ngine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing v
ehicle and of the trailer, observing the
re
commended
p
ressures.
Lighting
F Check the electrical lighting and signalling o
n the trailer and the hadlamp beam height
o
f your vehicle.
For
more information on adjusting the
h
eadlamp beam height, refer to the
c
orresponding
s
ection.
The
rear parking sensors will be
d
eactivated automatically if a genuine
C
ITROËN towbar is used.

Coolant level
The coolant level should be close to the "MA X" mark but should never
e
xceed it.
In
addition, as the cooling system is pressurised,
w
ait
at
least one hour after switching off the
e
ngine
before carrying out any work.
To
avoid
any risk of scalding, unscrew the cap by
t
wo
turns
to allow the pressure to drop. When the
p
ressure
has dropped, remove the cap and top
u
p
the
level.
Changing the coolant
The coolant does not have to be replaced at routine services.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When the engine is warm, the temperature of
t
he coolant is regulated by the fan.
Fluid specification
The coolant must conform to the ma
nufacturer's r ecommendations.
