●
Use s uit
able straps to secure heavy ob-
jects.
● During sudden manoeuvres or accidents,
loose ob
jects can be thrown forward, injuring
vehicle occupants or passers-by. This in-
creased risk of injury will be further increased
if a loose object is struck by an inflating air-
bag. If this happens, objects may shoot out-
ward like a missile. Risk of fatal injury.
● Please note that the centre of gravity may
shift when tr
ansporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Therefore, it is essential to adjust
your speed and driving style accordingly, to
avoid accidents.
● Never exceed the allowed axle weights or
allo
wed maximum weight. If said weights are
exceeded, the driving characteristics of the
vehicle may change, leading to accidents, in-
juries and damage to the vehicle.
● Never leave your vehicle unattended, espe-
cia
lly when the rear lid is open. Children
could climb into the luggage compartment,
closing the door behind them; they will be
trapped and run the risk of death.
● Never allow children to play in or around
the vehic
le. Close and lock all the doors and
the rear lid when you leave the vehicle. Be-
fore you lock the vehicle, make sure that
there are no adults or children in the vehicle. Note
● Air cir c

ulation in the vehicle helps reduce
fogging of the windows. Used air escapes
through ventilation slits in the side trim of
the luggage compartment. Ensure that the
ventilation slots are never covered.
● Straps for securing the load to the fasten-
ing ring
s are commercially available. Luggage compartment shelf

If unsuitable or damaged belts or retaining
str ap

s are used, they could break in the event
of braking or an accident. Objects could then
be launched across the passenger compart-
ment and cause serious or fatal injuries.
● Always use belts or retaining straps that

able and in a good condition.
● Belts and retaining straps should be se-
curely
fastened to the fastening rings.
● Objects in the luggage compartment that
are un
secured could move suddenly and mod-

● Secure all objects, little and large.
● Never exceed the maximum tensile load of
the fas
tening ring when securing objects.
● Never secure a child seat to the fastening
rings. Note
● The max imum t

ensile load that the fasten-

Belt s

and securing systems for the appro-
