Access
Ensure that any luggage or accessories
carried on the roof bars do not interfere
with the movement of the sunroof.
Do not place heavy loads on the movable
glass panel of the sunroof.
If the sunroof is wet, following a shower
or washing the vehicle, wait until it is
completely dry before opening.
Do not operate the sunroof if it is covered by
snow or ice - risk of damage!
Use only plastic scrapers to remove snow or
ice from the sunroof.
Regularly check the condition of the
sunroof seals (e.g. presence of dust,
dead leaves).
If using a car wash, check first that the roof is
correctly closed and keep the high-pressure
jet at least 30 centimetres from the seals.
Never leave the vehicle with the sunroof
open.
Operation
When opening the sunroof fully, the movable
glass moves to a partially open position, then
slides over the roof. Any intermediate position is
possible.

Before operating the sunroof control
button, ensure that no object or person
might prevent the movement.
Pay particular attention to children when
operating the sunroof.
If something is trapped when operating the
sunroof, reverse the movement of the sunroof
by pressing the control button in question.
The driver must ensure that passengers use
the sunroof correctly.
Any manual intervention on the position of
the sunroof may disturb the anti-pinch device.
Perform a reinitialisation.
Anti-pinch system
If the sunroof encounters an obstacle when
closing, the movement is automatically reversed.
Opening/closing the sunroof
► To open the sunroof, use the part of the
button located towards the rear.
► To close the sunroof, use the part of the
button located towards the front.
Operating the button
► Pressing the button beyond its point of
resistance opens or closes the sunroof fully.
► Pressing the button again stops the
movement in progress.
► By keeping the button pressed (without going
beyond the point of resistance), the movement of
the glass stops when this button is released.
► When the sunroof is closed: pressing once
without passing the point of resistance moves it
to the partially open position.
► When the sunroof is partially open: pressing
once on the front part of the button, without
going beyond the point of resistance, closes it
completely.
The sunroof and windows can be closed
by holding down the remote control
locking button.
Opening/closing the blind
► To open the blind, pull its handle backwards
until the desired position is reached.
► To close the blind, push its handle forwards
until the desired position is reached.
Reinitialisation
Reinitialisation is required after reconnecting the
battery, or if the sunroof malfunctions or moves
in a jerky manner.
► Check that nothing is affecting the movement
of the sunroof and that the seals are clean.
► With the ignition on, press and hold
the front part of the button to close the
sunroof.
The sunroof closes step by step. When fully
closed, it performs a slight opening/closing
movement.
► Release the button 1 second after the end of
the movement.
