occupant in the best position in relation to the
air bag.
The seat belt system comprises: R
Seat belts R
Emergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear R
Seat belt force limiters for the front seat belts
and the outer seat belts in the rear
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the front seats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants during an accident.
! If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, in the event of an accident, the Emer-
gency Tensioning Device and front-passenger
front air bag may be triggered and would need
to be replaced.
Important safety notes The use of seat belts and child restraint systems
is required by law in: R
all 50 states R
the U.S. territories R
the District of Columbia R
all Canadian provinces
Even where this is not required by law, all vehicle
occupants should correctly fasten their seat
belts before starting the journey.
G WARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit-
ting properly.
G WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
G WARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) tall in suitable additional restraint
systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle: R
always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-Occupant safety 43
Safety Z

Window curtain air bags
Window curtain air bags C are integrated into
the side of the roof frame and deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
In the event of a side impact, the window curtain
air bag is deployed on the side on which the
impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
( Y
page 53).
Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag and front-passenger knee bag are
either enabled or deactivated.
The system does not deactivate: R
the side impact air bag R
the pelvis air bag R
the window curtain air bag R
the Emergency Tensioning Devices Requirements 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 possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, 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. a
cushion. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation and operating
instructions.

Safety

You can thus avoid the risks that could arise as
a result of: R
an incorrectly categorized person in the front-
passenger seat R
the unintentional deactivation of the front-
passenger front air bag R
the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facing child restraint system If it is absolutely necessary to install a rearward-
facing child restraint system on the front-
passenger seat, always make sure that the
front-passenger front air bag is deactivated.
Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit ( Y
page 42) is the front-
passenger front air bag deactivated.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.
Forward-facing child restraint system If it is absolutely necessary to install a forward-
facing child restraint system on the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not touch
the roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Always make sure that the shoulder belt strap is
correctly routed from the vehicle belt outlet to
the shoulder belt guide on the child restraint
system. The shoulder belt strap must be routed
forwards and downwards from the vehicle belt
outlet. If necessary, adjust the vehicle belt out-
let and the front-passenger seat accordingly.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions. Child-proof locks

Important safet y notesIf you fail to adapt your drivin g style or if you are
inattentive , th e drivin g safet y systems can nei-
ther reduce th e ris k of an acciden t no r override
th e laws of physics. Driving safet y systems are
merely aids designed to assist driving. You are
responsible fo r maintainin g th e distanc e to th e
vehicle in front, fo r vehicle speed, fo r braking in
goo d time, and fo r stayin g in lane. Always adapt
your drivin g style to suit th e prevailin g road and
weather condition s and maintain a saf e distanc e
from th e vehicle in front. Drive carefully.
The drivin g safet y systems described only wor k
as effectively as possible when there is ade-
quat e contact between th e tires and th e road
surface. Pay particular attention to th e informa-
tion regardin g tires , recommended minimum
tire tread depths etc. in th e "Wheels and tires "
section ( Y
page 292).
In wintr y drivin g conditions, always use winte r
tires (M+ S tires )a nd if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 64).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 229) and dis-
play messages which may be shown in the
instrument cluster ( Y
page 204).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving.64
