To be classified correctly, the frontp
assenger
must sit:
R with the seat belt fastened correctly
R in ap osition that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by lean-
ing on armrests), OCS may not be able to
approximate the occupant's weight category.
In order to determin ewhether or not the front
passenger has been detected, both the driver and the frontp assenger should observe the
00730074 indicator lamp.
If the front-passenger seat, the seat cover or the seat cushion are damaged, have the nec- essary repair work carried out at an author-
ized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz. G
WARNING
If the 00730074 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or alarger person, ask the passenger to
reposition themselves on the seat so that the
00730074 indicator lamp goes out.
In the event of acollision, the air bag control
unit will not allow front-passenger fronta ir
bag and front-passenger knee bag deploy-
ment when the OCS has classified the front-
passenger occupant as weighing as much as
or less than atypical 12-month-old child in a
standard child restraint or if the front-
passenger seat is classified as being unoccu-
pied.
If OCS has detected that the frontp assenger
weighs the same as or less than atypical 12-
month-old child in astandard child restraint
system, the 00730074indicator lamp lights
up when the engine is started and remains lit. This indicates that the front-passenger front
air bag is deactivated.
If OCS determines that the front-passenger
seat is unoccupied, the 00730074indicator lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger fronta
ir bag and front-
passenger knee bag are deactivated.
If OCS determines that the frontp assenger
weighs more than atypical 12 montho ld child
in as tandard child restraint system and clas-
sifies this as asmall person (e.g. ateenager or
small adult), the 00730074indicator lamp
lights up for approximately 6seconds when
the engine is started. Dependin gonoccupant
weight sensor readings from the seat, it will
then remain illuminated or go out. If the
00730074 indicator lamp is illuminated, the
front-passenger fronta ir bag is deactivated.
With the 00730074 indicator lamp out, the
front-passenger fronta ir bag and front-
passenger knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person, the 00730074 indicator lamp lights up for
approximately 6seconds when the engine is
started and then goes out. This shows that the
front-passenger fronta ir bag and front-
passenger knee bag are activated.
If the 00730074 indicator lamp is illuminated,
the front-passenger fronta ir bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 00730074 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
R in the event of certain frontal impacts
R if the impact exceeds apreset deployment
threshold
R independently of the other air bags
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the frontp assenger's weight category as
determined by the OCS

Characteristics of activated SPORT han-
dling mode
SPORT handling mode raises the intervention threshold for stabilizing the vehicle. This
allows for asportier driving style on desig-
nated race circuits and may in certain situa-
tions improve the traction in comparison with
ESP ®
.
If SPORT handling mode is activated and one or more wheels start to spin, the 0089warn-
ing lamp in the instrument cluster flashes.
ESP ®
only stabilizes the vehicle to alimited
degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is only restricted to alimited
degree, and the drive wheels are able to
spin. The spinning wheels produce acut-
ting effect for better traction. Characteristics when ESP
®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 0089warning lamp in the
instrument cluster does not flash. In such sit-
uations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in acutting action for
better traction.
R traction control is still activated.
R ESP ®

tion)
i Observe the "Important safety notes" sec-
tion (Y page 54).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapty our driving style
to the different handling characteristics. Have the brake system checked at aqualified spe-
cialist workshop.

warning lamps (Y page 192) as well as dis-
play messages (Y page 166). ADAPTIVE BRAKE
