Occupant safety
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 comprises:
RSeat belt system
RAir bags
The components of the 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 84)
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 84). You also have to make sure that an air bag can
inflate properly if deployed(
Ypage 43).
An air bag supplements acorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the 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 accident occurs, only
the air bags that increase protection in that par-ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against object spenetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 50).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (
Ypage 53).
Important safety notes
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
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
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 1-800F OR-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.

If the driver or front passenger unfasten their
seat belts during the journey, the seat belt warn-
ing is activated again.
Air bags
Introduction
The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt. The
air bag providesa dditional protection in appli-
cable accident situations.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another (
Ypage 50).
However, no system available today can com-
pletelye liminate injuries and fatalities.
It is also not possible to rule out arisk of injury
cause dbyana ir bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed .This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Alway smake sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust the seats properlyb efore beginning
you rjourney. Alway smake sure that the seat
is in an almostu pright position. The center of the head restraint must support the head at
aboute
ye level.
RMove the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.
This allows the air bag to be full ydeployed.
RAlway sleana gainst the backrest whiled riv-
ing. Do not leanf orward or leanagainst the
door or side window.Y ou may otherwise be in
the deployment area of the air bags.
RAlway skeep you rfeet in the footwell in front
of the seat. Do not put you rfeet on the dash-
board,f or example.Y our feet may otherwise
be in the deployment area of the air bag.
RFor this reason, always secure persons less
than 5ft(1.5 0m )tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If ac hildist raveling in your vehicle, also
observe the following notes:
RAlway ssecure childrenu nder twelve years of
age and less than 5ft(1.50 m)tallins uitable

56Driving safety systems
Safety

You are responsible for maintainingthe distance
to the vehicle in front, for vehicle speed, for
braking in good time, and for stayin ginlane.
Always adapt your drivings tyle to suit the pre-
vailing road and weather condition sand main-
tain asafe distance from the vehicle in front.
Drive carefully.
The drivings afetysystems described only work
as effectively as possible when there is ade-
quate contac tbetwee nthe tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tir et read depth setc.int he "Wheels and tires"
section (
Ypage 260).
In wintry drivingc onditions, always use winter
tires (M+S tires) and if necessary, sno wchains.
Only in this way will the drivings afetysystems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
Genera linformation
AB Sregulates brakep ressure in suchaway that
the wheels do not lock when you brake. This
allows you to continue steeringt he vehicle when
braking.
The ! ABSw arnin glamp in the instrument
cluster lightsupw hen the ignition is switched
on. It goes out when the engin eisrunning.
AB Sw orksf romaspeed of about 5mph
(8 km/h), regardless of road-surfacec onditions.
AB Sw orksons lippery surfaces, even when you
only brakeg ently.
Important safetyn otes
iObserve the "Importan tsafetyn otes" sec-
tion (Ypage 56).
GWARNING
If AB Sism alfunctioning, the wheels could
lock when braking. The steerabilitya nd brak-
ing characteristics would be severely affec-
ted. There is an increased danger of skidding and accidents.
Drive on carefully. Have AB Schecked imme-
diately at aqualified specialis tworkshop.
When AB Sismalfunctioning, other systems,
including drivings afetysystems, will also becom
einoperative .Observe the information
on the AB Swarnin glamp (
Ypage 204) and dis-
play messages which may be shown in the

Brakes
XIf ABS intervenes: continue to depresst he
brakep edal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brakep edal with full force.
If AB Sintervenes when braking, you will feel a
pulsing in the brakep edal.
The pulsatin gbrakep edal can be an indication
of hazardous road conditions, and function sasa
reminder to tak eextra care while driving.
BAS (Brake Assist System)
Genera linformation
BA So perates in emergenc ybraking situations.
If you depresst he brakepedal quickly, BAS
automatically boostst he braking force, thus
shortening the stopping distance.
Important safetyn otes
iObserve the "Importan tsafetyn otes" sec-
