Advice
If one of the doors or the boot is still open
or if the electronic key for the Keyless
Entry and Start

system has been left inside
the vehicle, central locking will not take place.

boot are not subsequently opened, the
vehicle will automatically lock itself again after
about 30
seconds. If the vehicle is fitted with
an alarm, it will be reactivated automatically.

taking the Keyless Entry and Start system’s
electronic key with you.

the key is present in one of the defined areas
while the vehicle is unlocked.
In order to preserve the battery in the
electronic key and the vehicle's battery:

snow or ice - risk of damage!
Use only plastic scrapers to remove snow or
ice from the sunroof.

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
