In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
ț Seat belts
ț Emergency tensioning device
ț Air bags
ț Child seats
ț Child seat recognition
ț Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each
other.
The 1 indicator lamp in the instrument
cluster (
୴ page 24) comes on:
ț for about 4 seconds when you turn the
SmartKey in the starter switch to
position 1.
ț for about 4 seconds when you start the
engine by turning the SmartKey.
The 1 indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
A malfunction in the system has been
detected if the 1 indicator lamp:
ț fails to extinguish after approximately
4 seconds.
ț does not come on at all.
ț comes on after the engine was started
or while driving.
For safety reasons, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
