Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please
note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 20). Occupant safety
Overview of occupant safety
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
R LATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints
R air bag system components with:
-45
indicator lamp
- front-passenger seat with BabySmart™
automatic child recognition
The different air bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each
other. Not all air bags are deployed
in an accident. G
WARNING
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead to
the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See "Children in the vehicle"
(Y page 47) for further information on
infants and
children traveling in the vehicle
as well as on child restraint systems. SRS
(Supplemental Restraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R
the + SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R seat belt force limiters
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
+
SRS
warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. 32
Occupant safety
Safety
G
WARNING
The SRS self-check has detected a
malfunction if the + SRS indicator lamp:
R does not light up at all
R does not go out after approximately four
seconds after the engine is started
R lights up
after the engine is started or while
the vehicle is in motion
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at a qualified
specialist workshop. SRS may otherwise fail
to activate when it is needed in the event of
an accident, which could lead to serious or
fatal injuries. SRS might also be activated
unexpectedly and unnecessarily, which could
also result in injury.
In addition, work carried out improperly on
SRS may render SRS inoperative or cause
unintended air bag deployment. Work on the
SRS system should only be carried out by
qualified specialist personnel. Consult a
qualified specialist workshop.
If it is necessary to modify an air bag system
to accommodate a person 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).
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags G
WARNING
R Damaged seat
belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the environment.
Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags
and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any component
or part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, front-passenger front air bag
cover, outer sides of the seat backrests,
door trim panels, or door frame trims.
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
R Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
R Air bag system components will be hot after
an air bag has inflated. Do not touch them.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R Improper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be Occupant safety

Driver's air bag
: deploys in front of the
steering wheel; front-passenger front air
bag ; deploys
in front of and above the glove
box.
They are deployed:
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other air bags in the
vehicle
If the vehicle overturns, the front air bags are
generally not deployed unless the system
detects high vehicle deceleration in a
longitudinal direction.
Your vehicle has an adaptive, two-stage
driver's air bag. In the event of a collision, the
air bag control unit evaluates the vehicle
deceleration. When the first deployment
threshold is reached, the front air bag is filled
with enough propellant gas to reduce the risk
of injuries. The front air bag is fully deployed
if a second deployment threshold is exceeded
within a few milliseconds.
The front air bags will not deploy in impacts
with vehicle deceleration or acceleration
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. The front-passenger front air bag will only
deploy if:
R
the front-passenger seat is occupied.
R the 45 indicator
lamp in the center
console is not lit (Y page 37).
R the impact exceeds a preset deployment
threshold.
The front-passenger air bag is automatically
activated and deactivated. Both driver and
passenger should always check whether the
front-passenger air bag is activated or
deactivated.
The deployment of the driver's air bag does
not mean that the front-passenger air bag will
also deploy. If the system recognizes that the
front-passenger seat is empty, the front-
passenger air bag does not deploy even if the
impact fulfills the criteria and the driver's air
bag has deployed.
If the front-passenger seat is recognized as
occupied, the 45 indicator lamp lights
up for approximately six seconds if
R you turn the SmartKey to position 1 or 2 in
the ignition lock.
R the engine is running and then you switch
it off.
This indicates the operational readiness of
the front-passenger air bag.
Note that objects placed on the front-
passenger seat may cause the system to
recognize the seat as occupied. This can
result in the deployment of the front-
passenger air bag if the impact fulfills the
specified criteria. If the 45 indicator
lamp is lit up, the front-passenger air bag is
deactivated and will not deploy should the
situation arise. If indicator lamp 45 is
not lit up, the front-passenger air bag is
activated and will deploy should the situation
arise. G
WARNING
Your vehicle is equipped with air bag
technology which disables the front- 36
Occupant safety
Safety
Observe the manufacturer's instructions
when installing special child restraint
systems.
Special child restraint systems which are
compatible with BabySmart™ are necessary
for deactivating the front-passenger air bag.
When the special BabySmart™-compatible
child restraint system is installed correctly
and
is
recognized by the sensor system in the
front-passenger seat, the front-passenger air
bag is deactivated. In this case, 45
indicator lamp : lights up. If you have any
questions regarding the special BabySmart™-
compatible child restraint systems, consult
an authorized Mercedes-Benz Center.
If the SmartKey has been removed from the
ignition lock or is in position 0, 45
indicator lamp : does not light up.
The system does not deactivate:
R the window curtain air bag
R the Emergency Tensioning Devices
System self-test The
45
indicator
lamp lights up when
the SmartKey is turned to position 1 or 2 in
the ignition lock.
The 45 indicator lamp goes out after
approximately six seconds.
If the 45 indicator lamp does not light
up or is always lit, then the system is
malfunctioning. Have the BabySmart™
system checked at an authorized Mercedes- Benz Center before transporting a child on
the front-passenger seat.
For further information, see "Problems with
air bag deactivation system"
(Y
page 40). G
WARNING
Do not leave any switched on notebooks,
mobile phones, electronic tags (e.g. a ski
pass) or similar electronic devices on the
front-passenger seat. Signals emitted from
such devices can interfere with the
BabySmart™ air bag deactivation system.
Such interference can lead to the 45
indicator lamp
not lighting up during the self-
test.
If the + SRS warning lamp and the
4/ indicator lamp light up
simultaneously in the instrument cluster, the
system is malfunctioning. The front-
passenger air bag could deploy without cause,
or may fail to deploy in the event of an
accident.
Have the system checked as soon as possible
at an authorized Mercedes-Benz Center. Occupant safety

X Have the BabySmart™ system checked as soon as possible at
an authorized Mercedes-Benz Center. G
WARNING
If the 45
indicator
lamp illuminates and remains illuminated when the weight of a typical
adult or someone larger than a small individual has been detected on the passenger seat, do not
allow any occupant to use the passenger seat until the system has been repaired. Problem Possible causes/consequences and
M SolutionsThe 45
indicator
lamp
does not
light up and/or stay on
when a BabySmart™-
compatible child
restraint system is
installed on the front-
passenger seat. The BabySmart™ system is malfunctioning.
X
Make sure there is nothing between the seat cushion and the
child restraint system.
X Check that the child restraint system is installed correctly.
X If the 45 indicator lamp does not light up, have the
BabySmart™ system checked as soon as possible at an
authorized Mercedes-Benz Center.
Do not transport a child on the front-passenger seat until the
air bag deactivation system has been repaired. NECK-PRO head restraints
Important safety notes The NECK-PRO head restraints increase
protection to the driver's and the front
passenger's head and neck. The NECK-PRO
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards
in
the event of a rear-end collision of
a certain severity. This provides better head
support. G
WARNING
Do not secure any objects (e.g. coat hangers)
on the
NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly.
Consequently, the
NECK-PRO head restraints
cannot provide the intended level of
protection. Do not use head restraint covers. 40
