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 105).
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 104).
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
Occupant safetySafety

The shoulder section of the seat belt must
always be routed across the center of the
shoulder. Adjust the belt sash guide if neces-
sary.
X To raise: slide the belt guide upwards.
The belt guide will engage in various posi-
tions.
X To lower: hold belt guide release 0043and
slide the belt guide downwards.
X Let go of belt guide release 0043in the
desired position and make sure that the
belt guide engages.
All seat belts except the driver's seat belt are equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
(Y page 61).
Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. X
Press release button 0043, hold belt
tongue 0044and guide it back towards belt
outlet 0087.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the belt tongue is engaged in the buckle
and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(Y page 280).
Belt warning for the driver and front
passenger The
0076 seat belt warning lamp in the instru-
ment cluster is a reminder that all occupants
must fasten their seat belts. It may light up
continuously or flash. In addition, there may
be a warning tone.
Regardless of whether the driver's and front- passenger seat belts have already been fas-
tened, the 0076seat belt warning lamp lights
up for six seconds each time the engine is
started. If, after six seconds, the driver or
front-passenger seat belt has not been fas-
tened and the doors are closed, the 0076seat
belt warning lamp lights up. As soon as the
driver's and front-passenger seat belts are
fastened or a front door is opened again, the
0076 seat belt warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after Occupant safety
49Safety Z

When deployed, the window curtain air bag
offers additional protection for the head.
However, it does not protect your chest or
arms.
In the event of a side impact, the window cur-
tain air bag is deployed on the side on which
the impact occurs.
If the system determines that window curtain air bag deployment can offer additional pro-
tection to that provided by the seat belt, a
window curtain air bag may deploy in other
accident situations (Y page 58).Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
In the following situation, the side impact air
bag and Emergency Tensioning Device are
disabled: the OCS system detects that the
front-passenger seat is occupied, but the seat belt tongue is not inserted in the belt buckle
of the front-passenger seat.
Prerequisites To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their
back against the seat backrest
R with their feet resting on the floor, if possi-
ble If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
R transfers their weight by supporting them-
selves on a vehicle armrest
R sits in such a way that their weight is raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the
seat cushion of the front-passenger seat. The
backrest of the forwards-facing child restraint system must, as far as possible, be resting on
the backrest of the front-passenger seat.
The child restraint system must not touch the roof or be put under strain by the head
restraint. Adjust the angle of the seat back-
rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.

When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the traf-
fic situation.
BAS PLUS provides braking assistance in haz- ardous situations with vehicles in front within
a speed range between 4 mph (7 km/h) and
155 mph (250 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also react to sta-
tionary objects. Examples of stationary
objects are stopped or parked vehicles.
i If BAS PLUS demands particularly high
braking force, preventative passenger pro-
tection measures (PRE-SAFE ®
) are activa-
ted simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again, if:
R you release the brake pedal.
R there is no longer a risk of collision.
R no obstacle is detected in front of your
vehicle.
If you have activated DSR (Y page 250), BAS
PLUS is likewise deactivated. COLLISION PREVENTION ASSIST
General notes COLLISION PREVENTION ASSIST consists of
Adaptive Brake Assist and the distance warn-
ing function, which are described in the fol-
lowing.
Distance warning function Important safety notes
i Observe the "Important safety notes" sec-
tion (Y page 67). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely solely on the distance
warning function.
Function X To activate/deactivate: activate or deac-
tivate the distance warning function in the
on-board computer (Y page 275).
If the distance warning function is not activa-
ted, the 00D4symbol appears in the assis-
tance graphics display.
The distance warning function can help you to minimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically. The
distance warning function cannot prevent a
collision without your intervention.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound, 70
