55 Restraint systems
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index The following system components are monitored or
undergo a selfcheck: crash-sensor(s), airbag ignition
circuits, seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the key is turned from steering lock
position 0 to positions 1 or 2, malfunctions in the crash-
sensor are detected and indicated (the “SRS” indicator
lamp stays on longer than 4 seconds or does not come
on). In the operational mode, after the indicator lamp
has gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and passenger seat belt buckle harnesses, and
low voltage in the entire system are detected and
indicated.
Have the system checked at your authorized
Mercedes-Benz Center immediately.
Wa r n i n g !
In the event a malfu nction of th e “SRS” is indic ated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized Mercedes-
Benz Center immediately to have the system
checked; otherwise the “SRS” may not be activated
when needed in an accident, which could result in
serious or fatal injury, or it might deploy
unexpectedly and unnecessary which could also
result in injury.

63 Restraint systems
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care IndexUSA Models only:
Since 1986 all U.S. child restraints comply with U.S.
regulations without the use of a tether strap.
Wa r n i n g !
Children 12 years old and under must never ride in
this vehicle, except in a Mercedes-Benz authorized
BabySmart
TM compatible child seat, which operates
with the BabySmart
TM system installed in the
vehicle to deactivate the passenger front airbag
when it is properly installed. Otherwise they will
be struck by the airbag when it inflates in a crash.
If this happens, serious or fatal injury can result.
Infants and small children must be seated in an
appropriate infant or child restraint system, which
is properly secured with the vehicle’s seat belt,
fully in accordance with the child seat
manufacturer’s instructions.Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
Children too big for child restraint systems should
use regular seat belts. Position the shoulder belt
across chest and shoulder, not face or neck. A
booster seat may be necessary to achieve proper
belt positioning for children from 41 lbs. to the
point where a lap / shoulder belt fits properly
without one.When the child restraint is not in use, remove it
from the vehicle or secure it with the seat belt to
prevent the child restraint from becoming a
projectile in the event of an accident.

When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the kind
of vehicle operation. Driving at extreme speeds, and
cold starts combined with short distance driving in
which the engine does not reach normal operating
temperature, reduce the interval between services.
Model SLK 230 Kompressor
The FSS allows for distances between 10 000 miles
(Canada: 15 000 km) and 16 000 miles
(Canada: 25 000 km), or from 365 to 730 days between
