If the key is removed from the ignition lock or
is in position0, PASSENGER AIRBAG OFF
indicator lampCdoes not light up.
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag is deactivated
automatically for certain weight categories.
PASSENGER AIRBAG OFF indicator lampC
shows you the current status. If PASSENGER
AIRBAG OFF indicator lampCis lit, the front-
passenger front air bag is disabled.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe ETDs
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin a position that is as upright as possible
with their back against the seat backrest
Rwith their feet on the floor
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
display messages that can be displayed in the
instrument cluster (Ypage 301).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
Ris empty or occupied by the weight of a
typical child up to twelve months old,
seated in a child restraint system.
Ris occupied by a small individual, such as a
young teenager or a small adult.
Ris occupied by a child in a child restraint
system whose weight is greater than that
of a typical twelve month old child.
These are examples of when the OCS
deactivates the front-passenger front air bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
System self-test
GWARNING
If thestindicator lamp does not
illuminate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
GWARNING
Objects between the seat surface and the
child restraint system could affect the
function of the OCS. This could result in the
front-passenger front air bag not functioning
as intended during an accident. This poses an
increased risk of injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. Make
sure that the bottom and back of the child
restraint system make full contact with the
front-passenger seat cushion and backrest.

and
Rif a vehicle speed of 15 mph (25 km/h) is
exceeded, thevseat belt warning lamp
begins to flash. A warning tone also sounds
with increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
vseat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. Thevseat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated. Thevseat
belt warning lamp flashes again if the vehicle
speed exceeds 15 mph (25 km/h).
Thevseat belt warning lamp only goes
out if:
Rboth the driver and the front passenger
have fastened their seat belts.
or
Rthe vehicle is stationary and a door is open.
iFor more information on thevseat
belt warning lamp, see "Warning and
indicator lamps in the instrument cluster,
seat belts" (Ypage 324).
Emergency Tensioning Devices, seat
belt force limiters
GWARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer
operational and are unable to perform their
intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency
Tensioning Devices which have been
triggered immediately replaced at a qualified
specialist workshop.
!If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
iVehicles with PRE-SAFE®: an electric
motor is used by PRE-SAFE®to trigger the
tightening of the seat belt in hazardous
situations. This procedure is reversible.
The seat belts on the following seats have
Emergency Tensioning Devices and seat belt
force limiters:
Rdriver's and front-passenger seat
Rthe outer seats in the second row
Rthe seats in the third row
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This results in the force exerted on the
occupant being distributed over a greater
area.
The ETDs can only be activated when:
Rthe ignition is switched on
Rthe restraint systems are operational; see
"SRS warning lamp" (Ypage 43)
Rthe belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front
The Emergency Tensioning Devices on the
outside seats in the second row and on the
seats in the third row are triggered
independently of the lock status of the seat
belts.

Securing ringsDfor two LATCH-type
(ISOFIX) child restraint systems are installed
on the left and right:
Ron the rear seat backrests of the outer
seats in the second row
Ron the backrests of the seats in the third
row of seats
Before installing a LATCH-type (ISOFIX) child
restraint system in the second row:
XMove the rear seat backrests in the second
row to an upright position (Ypage 111).
XInstall the LATCH-type (ISOFIX) child
restraint system on both LATCH-type
(ISOFIX) securing ringsD. Comply with the
child restrain system manufacturer's
instructions when installing the LATCH-
type (ISOFIX) child restraint system.
Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
vehicle's seat belt system. Install the child
seat according to the manufacturer's
instructions.
Top Tether
Top Tether anchorages
GWARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an
accident, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g.
in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after
installing a Top Tether belt. Observe the lock
verification indicator. Adjust the rear seat
backrests so that they are positioned
vertically.
Top Tether provides an additional connection
between the LATCH-type (ISOFIX) child
restraint system secured with LATCH-type
(ISOFIX) and the rear seat. This helps reduce
the risk of injury even further. If the LATCH-
type (ISOFIX) child restraint system is
equipped with Top Tether, this should always
be used.
The Top Tether anchorages for the second
row of seats are installed on the rear of the
rear seat backrests. For the third row of seats,
use the cargo tie-down rings in the cargo
compartment floor.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster.

Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain a safe distance from
the vehicle in front. Drive carefully.
iThe driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Ypage 404).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
The%ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes
iObserve the "Important safety notes"
section (Ypage 67).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 326) and
display messages which may be shown in the
instrument cluster (Ypage 291).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently.
Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.

Exterior lighting
General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations.
Driving abroad
Conversion to symmetrical low beam
Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning
Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again.
