292 Practical hintsReplacing bulbs
Replacing bulbsSafe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment.

continue to be steered.
Alignment bolt
Metal pin with thread. The centering pin is
an aid used when changing a tire to align
the wheel with the wheel hub.
BabySmartTM airbag deactivation
system
This system detects if a special system
compatible child restraint seat is installed
on the front passenger seat. The system
will automatically deactivate the passen-
ger front airbag when such a seat is prop-
erly installed (indicator lamp 7 on the
center console lights up). See your autho-

ty.BabySmartTM compatible child seats
Special restraint system for children. The
sensor system for the passenger seat pre-
vents deployment of the passenger side
airbag if a BabySmartTM compatible child
seat is installed.

distances in emergency braking situa-
tions. The system is activated when it
senses an emergency based on how
