Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. The restraint system can also reduce the forces
to which vehicle occupants are subjected during an accident.
The restraint system includes the:
R seat belt system
R airbags
R child restraint system
R child seat securing system The components of the restraint system work in
conjunction with each other. They can only offerprotection if all vehicle occupants always:
R have the seat belt correctly fastened
(Y page 44)
R have the seat and head restraint adjusted
properly (Y page 106)
As the driver, you must also make sure that the
steering wheel is also adjusted properly.
Observe the information on the correct driver's
seat position (Y page 106).
In addition, you must make sure that the airbags can inflate properly if they are deployed
(Y page 46).
An airbag supplements a correctly worn seat
belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. The air-
bags are not deployed, for example, in the event
of an accident in which sufficient protection is
offered by the seat belt. In addition, only those
airbags, which in the applicable accident situa-
tions offer additional protection, are deployed in the event of an accident. However, the seat beltand airbag generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found under "Deployment of belt
tensioners and airbags" (Y page 53).
See "Children in the vehicle" for information on
children travelling with you in the vehicle as well
as on child restraint systems (Y page 56). Important safety notes

WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to adjust the vehicle to accom- modate a person with disabilities, contact a
qualified specialist workshop. Occupant safety

General notes
The section on the multimedia system in this
manual describes the basic principles for oper-
ation. More information can be found in the Dig-
ital Owner's Manual. Important safety notes

WARNING
If you operate information and communica-
tion equipment integrated in the vehicle when driving, you could be distracted from the traf-
fic situation. This could also cause you to lose control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the traffic
situation permits. If you cannot be sure of this,
stop the vehicle paying attention to road and
traffic conditions and operate the equipment
with the vehicle stationary.
You must observe the legal requirements for the
country in which you are currently driving when operating the multimedia system.
The multimedia system calculates the route to
the destination without taking the following into
account, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rules and regulations
The multimedia system may give incorrect driv-
ing recommendations if the actual road/traffic
situation does not correspond with the digital
map data.
For example:
R a diverted route
R the road layout or the direction of a one-way
street has been changed
For this reason, you must always observe road
and traffic rules and regulations during your
journey. Road and traffic rules and regulations
always have priority over multimedia system
driving recommendations. G
WARNING
Modifications to electronic components, their software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic components carried out at a qualified special-
ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid. Function restrictions
For safety reasons, some functions are restric-
ted or unavailable while the vehicle is in motion.
You will notice this, for example, because either you will not be able to select certain menu items
or a message will appear to this effect. Operating system
