Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe headbag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If you install a child restraint system on thefront-passenger seat, be sure to observe thecorrect positioning of the child restraint sys-tem. Never place objects under or behind thechild restraint system, e.g. a cushion. Fullyretract the seat cushion length. The entirebase of the child restraint system must alwaysrest on the seat cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat aspossible against the backrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.

CPASSENGER AIR BAG ON indicator lamp
DPASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether thefront-passenger front air bag is deactivated orenabled.
XPress the Start/Stop button once or twice,or turn the SmartKey to positionGorHinthe ignition lock.The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps mustlight up simultaneously for approximately sixseconds.
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for60 seconds, subsequently both indicatorlamps are off (PASSENGER AIR BAG ON andOFF): the front-passenger front air bag isable to deploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag display message appears in the instru-ment cluster (Ypage 215). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG OFF indicatorlamp. Be aware of the status of the front-

ProblemPossible causes/consequences andPPSolutions
The PASSENGER AIRBAG OFF indicator lamplights up and remainslit, even though thefront-passenger seat isoccupied by an adult ora person of a staturecorresponding to that ofan adult.
The classification of the person on the front-passenger seat is incor-rect.
XMake sure the conditions for a correct classification of the per-son on the front-passenger seat are met (Ypage 48).
XIf the PASSENGER AIR BAG OFF indicator lamp remains lit, thefront-passenger seat may not be used.
XHave OCS checked as soon as possible at an authorizedMercedes-Benz Center.
The PASSENGER AIRBAG OFF indicator lampdoes not light upand/or does not stayon.
The front-passengerseat is:
Runoccupied
Roccupied by theweight of a child upto twelve months oldin a child restraintsystem
OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and thechild seat.
XMake sure that the entire base of the child restraint system restson the seat cushion of the front-passenger seat. The backrest ofthe forward-facing child restraint system must lie as flat as possi-ble against the backrest of the front passenger seat. If necessary,adjust the position of the front-passenger seat.
XMake sure that the seat cushion length is fully retracted.
XWhen installing the child restraint system, make sure that theseat belt is tight. Do not pull the seat belt tight using the front-passenger seat adjustment. This could result in the seat belt andthe child restraint system being pulled too tightly.
XCheck for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to thechild restraint system. If necessary, adjust the head restraintaccordingly.
XMake sure that no objects are applying additional weight onto theseat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains offand/or the PASSENGER AIR BAG ON indicator lamp lights up, donot install a child restraint system on the front-passenger seat.
XHave OCS checked as soon as possible at an authorizedMercedes-Benz Center.
Roll bar
GDANGER
If the roll bar has developed a malfunction, it
may not function, e.g. in the event of an
accident. The roll bars may then not protect
the vehicle occupants as intended. This
poses an increased risk of injury or even
fatal injury.
Have roll bars checked immediately at a
qualified specialist workshop.
GWARNING
If you place objects or clothing on the roll
bar covers, these could impair roll bar exten-
sion. The roll bars may then not protect the
vehicle occupants as intended. In addition,
objects could endanger the vehicle occu-
pants when the roll bar is extending. This
poses an increased risk of injury or even
fatal injury.
Ensure that the movement area of the roll
bar covers is kept clear. Always stow all
objects in the vehicle correctly.

Safety

If you install a child restraint system on thefront passenger seat, be sure to observe theinstructions and safety notes on the "Occu-pant Classification System (OCS)" (Ypage 48).There you will also find information on disa-bling the front passenger front air bag.
All child restraint systems must meet the fol-lowing standards:
RU.S. Federal Motor Vehicle Safety Standards213 and 225
RCanadian Motor Vehicle Safety Standards213 and 210.2
Confirmation that the child restraint systemcorresponds to the standards can be found onan instruction label on the child restraint sys-tem. This confirmation can also be found inthe installation instructions that are includedwith the child restraint system.
Observe the warning labels in the vehicle inte-rior and on the child restraint system.
Child restraint system on the front-
passenger seat
General notes
If you install a child restraint system on thefront-passenger seat, always observe theinstructions and safety notes on the "Occu-pant Classification System (OCS)" (Ypage 48).
You can thus avoid the risks that could ariseas a result of:
Ran incorrectly categorized person in thefront-passenger seat
Rdeactivating the front passenger front airbag unintentionally
Rthe unsuitable positioning of the childrestraint system, e.g. too close to the dash-board
Rearward-facing child restraint system
If circumstances require you to secure a childin a rearward-facing child restraint system onthe front-passenger seat, always make surethat the front passenger front air bag is deacti-vated. Only if the PASSENGER AIR BAG OFFindicator lamp is lit continuously (Ypage 41),is the front passenger front air bag deactiva-ted.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.
Forward-facing child restraint system
If you secure a child in a forward-facing childrestraint system on the front-passenger seat,always move the front-passenger seat as farback as possible. Fully retract the seat cushionlength. The entire base of the child restraintsystem must always rest on the seat cushionof the front-passenger seat. The backrest ofthe child restraint system must lie as flat aspossible against the backrest of the front-passenger seat. The child restraint systemmust not touch the roof or be subjected to aload by the head restraint. Adjust the angle ofthe seat backrest and the head restraint posi-tion accordingly. Always make sure that theshoulder belt strap is correctly routed from thefront-passenger seat belt guide to the shoulderbelt guide on the child restraint system. Theshoulder belt strap must be routed forwardand down from the front-passenger seat beltguide. If necessary, adjust the front-passengerseat accordingly.
Always observe the child restraint systemmanufacturer's installation and operatinginstructions.
Pets in the vehicle
GWARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may press buttons
or switches, for instance.
In this way, animals may:
Ractivate vehicle equipment and become
trapped, for example
Rswitch systems on or off and thereby
endanger other road users
Furthermore, unsecured animals may be
flung around inside the vehicle in the event
of an accident or abrupt steering or braking
maneuver, and thereby injure vehicle occu-
pants. There is a risk of accident and injury.
Never leave animals unattended in the vehi-
cle.

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
Only operate this equipment when the vehi-
cle is stationary.
