Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Prerequisites
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their
back against the seat backrest
Rwith their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, 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 raised
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the seat cushion of the front-passenger seat. The
backrest of the forward-facing child restraint
system must lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the head
restraint. Adjust the angle of the seat back- rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.
Occupant Classification System opera-
tion (OCS)
PASSENGER AIR BAG OFF indicator lamp :
shows you whether the front-passenger front
air bag is deactivated.
XTurn the SmartKey to position 1or 2in the
ignition lock or on vehicles with KEYLESS-
GO, press the Start/Stop button once or
twice.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then displays the status of the front-
passenger front air bag. If the status of the
front-passenger front air bag changes while
the vehicle is in motion, an air bag display
message may appear in the instrument clus-
ter (
Ypage 198). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger
front air bag both before and during the jour-
ney.

Problems with the Occupant Classification System (OCS)
Be sure to observe the notes on "System self-test" (Ypage 60).
ProblemPossible causes/consequences andMSolutions
The PASSENGER AIR
BAG OFF indicator
lamp lights up and
remains lit, even
though the front-
passenger seat is occu-
pied by an adult or a
person of a stature cor-
responding to that of an
adult.The classification of the person on the front-passenger seat is
incorrect.
XMake sure the conditions for a correct classification of the per-
son on the front-passenger seat are met (
Ypage 58).
XIf the PASSENGER AIR BAG OFF indicator lamp remains lit, the
front-passenger seat may not be used.
XHave OCS checked as soon as possible at an authorized
Mercedes-Benz Center.
The PASSENGER AIR
BAG OFF indicator
lamp does not light up
and/or does not stay
on.
The front-passenger
seat is:
Runoccupied
Roccupied by the
weight of a child up
to 12 months old in a
child restraint sys-
tem
OCS is malfunctioning.
XMake sure there is nothing between the seat cushion and the
child seat.
XMake sure that the entire base of the child restraint system rests on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system must lie as flat as pos-
sible against the backrest of the front-passenger seat. If nec-
essary, adjust the position of the front-passenger seat.
XWhen installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight using the front-
passenger seat adjustment. This could result in the seat belt and
the 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 the
child restraint system. If necessary, adjust the head restraint
accordingly.
XMake sure that no objects are applying additional weight onto
the seat.
XIf the PASSENGER AIR BAG OFF indicator lamp remains off, do
not install a child restraint system on the front-passenger seat.
It is recommended that you install the child restraint system on
a suitable rear seat.
XHave OCS checked as soon as possible at an authorized
Mercedes-Benz Center.

Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install the child restraint system on a
rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the instructions and safety
notes on the "Occupant Classification System (OCS)" (
Ypage 58).
You can thus avoid the risks that could arise
as a result of:
Ran incorrectly categorized person in the
front-passenger seat
Rthe unintentional deactivation of the front-
passenger front air bag
Rthe unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facing child restraint system
If it is absolutely necessary to install a rear-
ward-facing child restraint system on the
front-passenger seat, always make sure that
the front-passenger front air bag is deactiva-
ted. Only if the PASSENGER AIR BAG OFF
indicator lamp is permanently lit (
Ypage 49)
is the front-passenger front air bag deactiva-
ted.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system
If it is absolutely necessary to install a
forward-facing child restraint system on the
front-passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not
touch the roof or be subjected to a load by the
head restraint. Adjust the angle of the seat
backrest and the head restraint position
accordingly. Always make sure that the shoul-
der belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down-
wards from the vehicle belt outlet. If neces-
sary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.
Always observe the child restraint system
manufacturer's installation and operating
instructions.

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 while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the coun-
try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle. If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
se cond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
