essary repair work carried out at a qualified
specialist workshop.
For safety reasons, Mercedes-Benz recom-
mends 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 posi-
tioned correctly. Observe also the air bag dis- play messages that can be displayed in the
instrument cluster (Y page 225).
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:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in a child restraint system.
R is occupied by a small individual, such as a
young teenager or a small adult.
R is 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 deacti- vates the front-passenger front air bag. Deac-
tivation takes place although the collision ful- fills the criteria for deploying the driver's air
bag.
For further information, see "Air bag display
messages" (Y page 225).
System self-test G
WARNING
If the 00730074indicator lamp does not illu-
minate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat. G
WARNING
Never place anything between seat cushion
and child seat (e.g. a pillow), since it reduces the effectiveness of the OCS. The underside
and rear side child restraint system must be placed entirely on the seat cushion and the
backrest of the front-passenger seat back-
rest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer's instructions for
installation of child restraint systems.
The PASSENGER AIR BAG OFF indicator lamp
lights up:
R if you turn the SmartKey in the ignition lock
to position 1or 2
R if an adult is seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The PASSENGER AIR BAG OFF indicator lamp
goes out again after approximately six sec-
onds.
If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the PASSENGER AIR BAG OFF indica- tor lamp will continue to light up. The
PASSENGER AIR BAG OFF indicator lamp will
not go out.
For further information, see "Problems with
the Occupant Classification System"

X Make sure there is nothing between the seat cushion and the
child seat.
X Make sure that the backrest and base of the child restraint sys-
tem are resting securely on the front-passenger seat. If neces-
sary, adjust the position of the front-passenger seat.
X When installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight with the front-
passenger seat adjustment. This could result in the seat belt
being pulled too tightly.
X Check the installation of the child restraint system.
X Make sure that no objects are applying additional weight onto
the seat.
X If the PASSENGER AIR BAG OFF indicator lamp remains off, have
the OCS checked immediately at a qualified specialist work-
shop. Do not transport a child on the front-passenger seat until the OCS has been repaired.
X Observe the additional display messages in the multifunction

51Safety Z

This allows you to continue steering the vehi-
cle when braking.
The 0025 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 i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 63).G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately 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 (Y page 245) and
display messages which may be shown in the
instrument cluster (Y page 214).
ABS works from a speed of about 5 mph
(8 km/h) , regardless of road-surface condi-
tions. ABS works on slippery roads, even if
you only brake gently.
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit- uation is over.
X To 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.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving. BAS (Brake Assist System)
General information BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 63). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. COLLISION PREVENTION ASSIST
General notes COLLISION PREVENTION ASSIST consists of
the Adaptive Brake Assist and the distance
warning function, which are described in the
following.
