CITROEN Grand C4 PICASSO Owner's Handbook Manual page 307

Recommendations
Distribute the load evenly, avoiding
overloading on one side.
Arrange the heaviest part of the load as
close as possible to the roof.
Anchor the load securely and fit a warning
flag if part of it overhangs the vehicle.
Drive gently, as the vehicle will be more
liable to the effects of side winds (vehicle
stability may be affected).
Remove the roof bars as soon as they are
no longer needed.
Maximum load, distributed over the roof
bars, for a loading height not exceeding
40 cm: 80 kg.
This value is subject to change, please
check the maximum load stated in the
instructions provided with he roof bars.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the profile of the
road to avoid damaging the roof bars
and the fixings on the vehicle.
Please refer to national legislation so as
to meet the requirements on carrying
objects that are longer than the vehicle.
When carrying long objects, it is
recommended that you deactivate the
motorised operation of the tailgate.
