2Ensure 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.

Safety
seats suited to their weight, on seats fitted with
a seat belt or ISOFIX mountings.
–

Statistically
, the safest seats in your
vehicle for carrying children are the rear
seats.
–

Children weighing less than 9 kg must
travel in the "rearward facing" position,
whether in the front or rear of the vehicle.
It is recommended that children travel
on the rear seats of the vehicle:
–

‘rearward facing’ up to the age of 3,
–

‘forward facing’ over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
Advice
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Ensure that there is no seat belt or seat belt
buckle under the child seat, as this could
destabilise it.
Remember to fasten the seat belts or the
harness of child seats, keeping the slack
relative to the child's body to a minimum,
even for short journeys.
When installing a child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it secures
the child seat firmly on the seat of the vehicle.
If the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on a
passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event of
sharp braking. Refit the head restraint once
the child seat has been removed.
Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
– a child alone and unattended in a vehicle,
– a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
–

the keys within reach of children inside the
vehicle.
Child seat at the rear
Forward-facing or rearward-facing



► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the forward-facing or rearward-facing
child seat itself do not touch the vehicle's front
seat.
►

Check that the backrest of the forward-facing
child seat is as close as possible to the backrest
of the vehicle's rear seat, and ideally in contact
with it.
Centre rear seat
A child seat with a support leg must never be
installed on the centre rear passenger seat .
