i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

Restraint system: introduction
The restraint system reduces the risk of occu-
pants hitting parts of the vehicle interior in the
event of an accident. Furthermore, the
restraint system may also reduce the forces
exerted on the vehicle occupants when an
accident occurs.
The restraint system includes:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer the intended level of protection if all
vehicle occupants:
R are correctly wearing their seat belts.
(Y page 47)
R adjust their seat and head restraint prop-
erly (Y page 107).
The driver is also responsible for ensuring
that the steering wheel has been correctly
positioned. Observe the information relating
to the correct driver's seat position
(Y page 106).
Always ensure the air bag can inflate properly if deployed (Y page 50).
An air bag supplements a correctly fastened
seat belt and is an additional safety device
providing increased protection for vehicle
occupants in appropriate accident situations.
For example, if the protection already provi-
ded by a correctly fastened seat belt will suf-
fice, the air bags are not deployed. Further-
more, only the air bags that would increase
the degree of protection afforded to the vehi- cle occupants in the event of an accident are deployed. Seat belts and air bags generally do
not protect against objects penetrating the
vehicle from the outside.
Information on the restraint system operation can be found under "Triggering of belt ten-
sioners and air bags" (Y page 58).44

No steering support is provided from STEER
CONTROL, if:

Immobilizer
X To activate with the SmartKey: remove

being started without the correct SmartKey.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Any-

In the event that the engine cannot be star-
ted when the starter battery is fully
charged, the immobilizer may be faulty.
