Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-cle occupant scomin ginto 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 occupant sare subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securings ystems
The component softhe restraint system work in
conjunction with each other .They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 74)
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 74).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 43).
An air bag supplement sacorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupant sinthe event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accidento ccurs,only
the air bags that increase protection in that par- ticular accidents ituation are deployed. How-
ever, seat belts and air bags generally do not
protec tagainst objects penetratin gthe vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 46).
See "Children in the vehicle" for information on
children travelin gwith you in the vehicle as well
as on child restraint systems (
Ypage 49).
Important safetyn otes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accidentort rigger unexpectedly, for example.
This poses an increased risk of injur yoreven
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
component sortheir software.
If it is necessary to modify component softhe
restraint system to accommodate aperson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
Assistance Center at 1-800-FOR-MERCedes
(1‑ 800‑367‑ 6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.
Restraint system warning lamp
The function softhe restraint system are
checked after the ignition is switched on and at
regular intervals while the engin eisrunning.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than afew sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after afew seconds with the
engin erunning
Rlights up again while the engin eisrunning

GWARNING
If yo ulea ve animals unattende dorunsecured

ABS (Anti-lock Brakin gSystem)
General information
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.
The yellow !ABS warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. It goe soutwhen the engine is run-
ning.
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, eve nwheny ou

gers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating materi-
als ,e.g. blankets, coats, bags, seat covers,
child seats or booster seats.

wards, the front seats cannot be moved to
their rearmost position. You coul dotherwise
damage the seats and the rear bench seat.
!Make sure that the sun visor is foldedu p
before adjusting the backrest and head
restraint height. The head restraint and sun
visor coul dotherwise collide when the head
restraint is full yextended.
