Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules.
Operation is subject to the following two
conditions: 1) These devices may not cause
harmful interference, and 2) These devices
must accept any interference received,
including interference that may cause
undesired operation. Changes or
modifications not expressly approved by the
party responsible for compliance could void
the user’s authority to operate the
equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference,
including interference that may cause
undesired operation of the device."
Diagnostics connection
GWARNING
If you connect equipment to the diagnostics
connection, it can affect the operation of the
vehicle systems. This can impair the operating
safety of your vehicle while driving. There is a
risk of accident.
Do not connect any equipment to the
diagnostics connection.
GWARNING
Loose equipment or equipment cables that
are connected to the diagnostics connection
can obstruct the area around the pedals. The
equipment or the cables could get between
the pedals in the event of sudden braking or
acceleration. As a result, the movement of the
pedals may be impaired. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
! If the engine is switched off and
equipment on the diagnostics connection
is used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to
emissions monitoring information being
reset. This may lead to the vehicle failing to
meet the requirements of the next emissions
test during the main inspection.
Qualified specialist workshop
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.
Observe the notes in the Maintenance
Booklet.
Always have the following work carried out at
an authorized Mercedes-Benz Center:
R work relevant to safety
R service and maintenance work
R repair work
R alterations, installation work and
modifications
R work on electronic components
Correct use
GWARNING
There are various warning stickers affixed to
your vehicle. Their purpose is to alert you and
others to various dangers. Therefore, do not
remove any warning stickers unless the
sticker clearly states that you may do so.
Introduction29Z
Rknee injuries
R thigh injuries
R lower leg injuries
Driver's knee bag =(Y page 48) deploys
below the steering wheel. During a frontal
impact, if the system determines that air bag
deployment can offer additional protection to
that provided by the seat belt, driver's knee
bag =(Y page 48) is deployed along with the
driver's air bag. Driver's knee
bag =(Y page 48) operates best in
conjunction with a properly positioned and
fastened seat belt.
Side impact air bagsGWARNING
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
Improper repair work on the doors or the
modification or addition of components to the
doors create a risk of rendering the side
impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Center.
GWARNING
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
When deployed, the side impact air bags offer
additional protection for the thorax of the
vehicle occupants on the side of the vehicle
on which the impact occurs. However, they
do not protect the:
R head
R neck
R arms
Front side impact air bags : and rear side
impact air bags ; deploy next to the outer
seat cushions.
The side impact air bags are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R independently of the use of the seat belt
R independently of the front air bags
R independently of the ETDs
If the vehicle overturns, the side impact air
bags are generally not deployed. Exception: if
the system detects high vehicle deceleration
or acceleration in a lateral direction and
determines that deployment can offer
additional protection to that provided by the
seat belt.
Side impact air bags will not deploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
Occupant safety49SafetyZ
The side impact air bag on the front-
passenger side will not deploy under the
following conditions:
R the OCS detects that the front-passenger
seat is not occupied.
R the front-passenger seat belt is not
fastened.
The side impact air bag on the front-
passenger side will deploy if the front-
passenger seat belt is fastened, regardless of
whether the front-passenger seat is occupied
or not.
Window curtain air bags
The window curtain air bags enhance the level
of protection for the head, but not chest or
arms, of the vehicle occupants on the side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area extending from the front door (A-
pillar) to the rear sidewall (C-pillar).
Window curtain air bags : are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R regardless of whether the front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that window curtain air bag
deployment can offer additional protection
to that provided by the seat belt
R independently of the front air bags
Window curtain air bags : will not deploy in
impacts with deceleration rates which do not
exceed the system's preset deployment
thresholds for vehicle deceleration or
acceleration. You will then be protected by
the fastened seat belt.
Occupant Classification System
(OCS)
How the Occupant Classification
System works
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat by means of a weight sensor.
The front-passenger front air bag is
deactivated automatically for certain weight
categories. The 42 indicator
lamp shows you the current status. If the
42 indicator lamp is illuminated,
the front-passenger front air bag is
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
