•There must be no other persons, animals or objects between the occu-
pants of the outer seats and the deployment space of the curtain airbags
so that the curtain airbag can deploy without restriction and provide the
greatest possible protection. Therefore, sun blinds which have not been
expressly approved for use in your vehicle may not be attached to the side
windows ⇒page 212, “Accessories, parts replacement and modifica-
tions”.•The built-in coat hooks should be used only for lightweight clothing. Do
not leave any heavy or sharp-edged objects in the pockets. Please, do not
hang the clothes on coat hangers.•The airbags provide protection for just one accident; replace them once
they have deployed.•Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lining)
should only be performed by a spec ialised workshop. Otherwise, faults
may occur during the airbag system operation.•Do not attempt to modify components of the airbag system in any way.•The side and head airbags are managed through sensors located in the
interior of the front doors. To ensure the correct functioning of the side and
head airbags neither the doors nor the door panels should be modified in
any way (e.g. fitting loudspeakers). If the front door is damaged, the airbag
system may not work correctly. All work carried out on the front door must
be made in a specialised workshop.WARNING (continued)

WARNING
•The driver is responsible for the proper position of the key-operated
switch. •Yo u s h o u l d d e a c t i v a te t h e f ro n t p a s s e n g e r a i r b a g o n l y i f yo u h a v e t o u s e
a rear-facing child seat in exceptional cases. ⇒ page 46, “Child safety”.•For those vehicles that do not include a key lock switch to turn the
airbag off, an Authorised Service Centre must be consulted.•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. Otherwise, there is a
risk of death. If under exceptional circumstances it is necessary to trans-
port a child in a rear-facing child seat on the front passenger seat, you must
always disable the front passenger airbag.•As soon as the child seat is no longer needed on the front passenger
seat, enable the front passenger airbag again.•Only deactivate the passenger airbag when the ignition is off, other-
wise a fault may occur in the airbag system, which could cause the airbag
to not deploy properly or not deploy at all.•When the passenger airbag is deactivated, if the warning lamp AIRBAG
OFF is not continuously lit up, there may be a fault in the airbag system:
−Have the airbag system inspected immediately by a specialised
workshop.
− Do not use a child seat on the front passenger seat! The front
passenger airbag could be triggered despite the fact that there is a fault
in the system and, as a result, a child could sustain serious or fatal inju-
ries.
− It is unpredictable whether the front passenger airbag will deploy in
the event of an accident. Warn all your passengers of this.
•When using the ignition key to activate/deactivate the front passenger
airbag, only the front passenger airbag will be activated/deactivated. The
side airbag and head airbag on the passenger side will remain active.WARNING (continued)

Safety notes on using child seats
Proper use of child seats substantially reduces the risk of
injury in an accident!As the driver, you are responsible for any children you transport in
your vehicle.
– Protect your children by properly using the appropriate child
seats ⇒page 48.
– Always ensure that the seat belt is properly positioned according to the instructions provided by the manufacturer of the child
seat.
– When travelling, do not allow children to distract you from traffic.
– Take breaks regularly during long trips. Take a break at least
every two hours.
WARNING
•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. This could lead to a
risk of potentially fatal injuries to the child! However, if it is necessary, in
exceptional cases, to transport a child in the front passenger seat, the front
passenger airbag must always be disabled ⇒page 44, “Deactivating
airbags*”. If the passenger seat has a height adjustment option, move it to
the highest position.•For those vehicles that do not include a key lock switch to disconnect
the airbag, the vehicle must be taken to a Technical Service.•All passengers, especially children, must assume the proper sitting
position and be properly belted in while travelling.
•Never hold children or babies on your lap, this can result in potentially
fatal injuries to the child!•Never allow a child to be transported in a vehicle without being properly
secured, or to stand up or kneel on a seat while travelling. In an accident,
the child could be flung through the vehicle, causing possibly fatal injuries
to themselves and to the other passengers.•If children assume an improper sitting position when the vehicle is
moving, they expose themselves to greater risk of injury in the event of a
sudden braking manoeuvre or in an accident. This is particularly important
if the child is travelling on the front passenger seat and the airbag system
is triggered in an accid ent ; as this could caus e s erious inj ur y or eve n deat h.•A suitable child seat can protect your child!•Never leave an unsupervised child alone on a child seat or in the
vehicle.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.•Children who are less than 1.5 metres tall must not wear a normal seat
belt without a child seat, as this could cause injuries to the abdominal and
neck areas during a sudden braking manoeuvre or in an accident.•Do not allow the seat belt to become twisted or jammed, or to rub on
any sharp edges.•Incorrectly worn seat belts can cause injuries even in a minor collision
or in sudden braking manoeuvres.•The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒page 24, “Seat belts”.•Only one child may occupy a child seat ⇒page 48, “Child seats”.WARNING (continued)

Securing child seatsWays to secure a child seat
A child seat can be secured differently on the rear seat and on
the front passenger seat.You can secure a child seat to the rear seat or front passenger seat in the
following ways:•Child seats in groups 0 to 3 can be secured with a seat belt.•Child seats in groups 0, 0+ and 1 with the ISOFIX and Top Tether* systems
can be secured without using the seatbelt, thanks to the ISOFIX and Top
Tether* securing rings ⇒ page 52.
U: Suitable for universal approved restraining systems for use in this age category (universal retention systems are those fitted using the adult
seat belt).
*: Move the front passenger seat as far back as possible, as high as possible and always deactivate the airbag.
L: Suitable for retention systems using the ISOFIX and Top Tether* anchors.
WARNING
•When travelling, children must be secured in the vehicle with a
restraint system suitable for age, weight and size.•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. This could cause fatal
injuries to the child! However, if, in exceptional cases, it is necessary to
transport a child in the front passenger seat, the front passenger airbag
⇒ page 44, “Deactivating airbags*” must always be disabled and the seat
adjusted to its highest position, where possible.•Read and always observe information and warnings concerning the use
of child seats ⇒ page 47.

Unlocking and locking101
Safety First
Operating Instructions
Practical Tips
Technical Specifications
Automatic speed dependent locking and unlocking system*
This is a safety system which prevent the access to the vehicle
from the outside when it is running (for example, when
stopped at a traffic light).Locking
The doors and the tailgate are automatically locked when vehicle speed
exceeds 15 km/h.
If the vehicle is stopped and one of the doors is opened, when the vehicle
moves off again and exceeds a speed of 15 km/h, the unlocked door(s) will
be locked once more.
Unlocking
The driver door automatically unlocks when the key is removed from the igni-
tion.
Each door can be unlocked and opened independently from the inside (for
example, when a passenger gets out of it). To do it, simply operate the lever
inside the door.
WARNING
The door handles must not be operated when the vehicle is running: the
door would open.Automatic locking system for involuntary unlocking*
It is an anti-theft system and prevents the unintentional
unlocking of the vehicle.If the vehicle is unlocked and any of the doors (including the tailgate) are
opened within 30 seconds, it gets re-locked automatically. This function prevents the vehicle from remaining unlocked if the unlock button is pressed
by mistake.
Emergency unlocking systemIf the airbags are triggered during an accident, the vehicle is unlocked, except
for the luggage compartment. It is possible to lock the vehicle from inside
with the central locking, after turning the ignition off and back on again.
If the doors must be locked from the outside, see “Emergency locking of the
doors”Central locking button
The central locking button allows you to lock and unlock the
vehicle from the inside.
