Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
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 systems are:
R Seat belts
R Child restraint systems
R "LATCH" type child seat mountings
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints
R PRE-SAFE ®
R Air bag system components with:
- PASSENGER air bag OFF indicator lamp
- USA only: front-passenger seat with
Occupant Classification System (OCS)
- Canada only: front-passenger seat with
BabySmart™ air bag deactivation system
The protective functions of the systems work
in conjunction with each other. The systems
are, however, autonomous.
GWarning!
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/
belt buckle tensioners, for example, could
deploy inadvertently or fail to deploy.
Therefore, never modify the restraint
systems. Do not tamper with electronic
components or their software.
i More information on the subject of
children in the vehicle and child restraint
systems can be found under the "Children
in the vehicle" chapter ( Y page 59).
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 + SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R ETDs/belt buckle tensioners
R belt force limiters
SRS warning lamps
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.
The SRS components are in operational
readiness when the + indicator lamp goes
out while the engine is running.

BA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 36
GWarning
The SRS self-check has detected a
malfunction if the + SRS warning lamp:
R does not illuminate
R goes out approximately 4 seconds after the
engine is started
R illuminates after the engine is started or
illuminates during the journey
For your safety, Mercedes-Benz recommends
that you have the system checked as soon as
possible at an authorized Mercedes-Benz
Center. Otherwise the SRS may not be
activated when it is needed in an accident,
which could result in serious or fatal injury.
The SRS might also deploy unexpectedly and
unnecessarily which could also result in
injury.
In addition, improper 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 performed
by qualified technicians. Contact an
authorized Mercedes-Benz Center.
Contact an authorized Mercedes-Benz Center
if it is necessary to modify an air bag system
to accommodate a person with disabilities.
USA only: Call our Customer Assistance
Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
GWarning
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. PRE-
SAFE ®
has electrically operated reversible
belt tensioners in addition to the
pyrotechnic ETDs.
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. to the:
- padded steering wheel boss
- knee bag covers
- front-passenger air bag cover
- outer side of front seat bolsters
- outer side of rear bench seat backrest
seat bolsters
- roof lining trim
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.Occupant safety37SafetyBA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 37Z
In addition, the occupant weight may appear
to increase or decrease due to the following:
R objects hanging on the seat
R objects lodged underneath the seat
R objects lodged between the seat and the
center console
R objects lodged between the seat and the
door
R other passengers exerting weight on the
seat
R objects applying pressure to the back of
the seat
Make sure that the seat always has clearance
in all directions.
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.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories which have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should observe the 42 indicator
lamp to determine whether or not the front
passenger is positioned correctly.GWarning!
If the 4 2 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 4 2 indicator lamp goes out,
or check whether objects are caught under or
around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-month-
old child in a standard child restraint or if the
front passenger seat is classified as being
empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 4 2 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 4 2 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
4 2 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the 4
2 indicator lamp illuminated, the
front passenger front air bag is deactivated.
With the 4 2 indicator lamp out,
the front passenger front air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 4 2 indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then goes out,
indicating that the front passenger front air
bag is activated.
If the 4 2 indicator lamp is
illuminated, the front passenger front air bag
is deactivated and will not be deployed.Occupant safety43SafetyBA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 43Z
Important information about using
KEYLESS-GO
R You can use the KEYLESS-GO key as a
conventional SmartKey.
R You can combine KEYLESS-GO functions
with those of a conventional SmartKey, e.g.
you can open the vehicle with KEYLESS-GO
and close it with the & button.
R Always carry your KEYLESS-GO key on your
person.
R Never store the KEYLESS-GO key together
with:
- electronic devices, such as a mobile
phone or other SmartKey
- metal objects, such as coins or metal foil
Doing so may impair the function of
KEYLESS-GO.
R To open or close the vehicle, the KEYLESS-
GO key should not be more than 3 ft (1 m)
from the door or tailgate.
R If the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull an outer door handle and
switch on the ignition to reactivate the
KEYLESS-GO function.
R If the KEYLESS-GO key is removed from the
vehicle, the system may not be able to
recognize the SmartKey anymore. The
vehicle can then no longer be locked or
started with KEYLESS-GO.
R If the KEYLESS-GO key has been removed
from the vehicle, e.g. when another vehicle
occupant with a KEYLESS-GO key leaves
the vehicle:
- when the Start/Stop button is pressed,
or when trying to lock the vehicle using
the locking button on the outside door
handle, the Key Not Detected message
appears in the multifunction display.
- when the engine is running, the red Key
Not Detected message appears in the
multifunction display as you pull away.
Look for the KEYLESS-GO key and place
it somewhere else in the vehicle. Place
the KEYLESS-GO key on the front-
passenger seat, for example, or in your
shirt pocket.
R If you have switched on the engine with the
Start/Stop button, you can switch it off
again by:
- pressing the Start/Stop button
- inserting the KEYLESS-GO key into the
ignition lock while the vehicle is at a
standstill and the automatic
transmission is in park position P.
R You may inadvertently unlock the vehicle if
the KEYLESS-GO key is less than 3 ft (1 m)
from the vehicle and:
- an exterior door handle is hit by a jet of
water, or
- you clean an exterior door handle
R Please note that any vehicle occupant can
start the engine when there is a KEYLESS-
GO key in the vehicle.
Scenario 1: There is a KEYLESS-GO key in
the vehicle and a second one outside the
vehicle. If you leave the KEYLESS-GO key
in the vehicle when you leave and lock the
vehicle, no message appears in the
multifunction display.
Scenario 2: There is a KEYLESS-GO key in
the vehicle, but none outside the vehicle. If
you get out of the vehicle and attempt to
lock it, the Key Detected In Vehicle
message appears in the multifunction
display. The vehicle is not then locked.
When starting the engine and whilst driving,
KEYLESS-GO also checks whether a valid
SmartKey is in the vehicle by periodically
establishing radio contact.74SmartKeyOpening and closing

Important safety notes
GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned by these
parts.GWarning!
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartment unless they are firmly secured
in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident
