Precautions In Use; Tailgate Release - CITROËN C4 Picasso Owner's Handbook Manual

Access
The motorised tailgate can be opened and
closed manually, even if motorisation is
activated.
When opening and closing a motorised tailgate
manually, there is no assistance from gas-filled
struts. Resistance to opening and closing is
therefore entirely normal.

This operation is necessary where there is no
movement - after detection of an obstacle, after
connecting or recharging the battery, ...
Open the tailgate by hand, if necessary.
Manually close the tailgate fully.
If the problem persists, contact a CITROËN
dealer or a qualified workshop.

Precautions in use

In the event of an accumulation of snow
on the tailgate, clear the snow before
commanding an automatic opening of
the tailgate.
The formation of ice can block the
tailgate and prevent its opening: wait
until the ice melts with the heating of the
passenger compartment.
When washing the vehicle in an
automatic car wash, don't forget to
lock your vehicle to avoid the risk of
unexpected opening.
Repeated opening and closing of the
tailgate can cause overheating of its
electric motor, after which opening and
closing will not be possible.
Allow 10 minutes for the motor to cool
down before operating the tailgate
again.
