Driving advice
Distribution of loads
F distribute the load in the trailer so that the heaviest items are as close as
p
ossible to the axle and the nose weight
a
pproaches the maximum permitted
w
ithout exceeding it.
ai
r density decreases with altitude, thus
reducing
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.
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
the
engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes on a long
m
ountain type of descent, the use of engine
b
raking 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.
Refer to the "Technical data" section for details
of
the
weights
and
towed
loads
which
apply
to
y
our
vehicle.
When
not
towing
a
trailer,
remove
the
q
uickly-detachable
tow
ball
before
d
riving. The
rear parking sensors will be
d
eactivated automatically if a genuine
