When leaving the vehicle, always remove the
SmartKey from the starter switch, take it

Unlocking
iWhen you switch on the ignition, the
indicator and warning lamps (except
high beam headlamp indicator lamp
and turn signal indicator lamps unless
activated) in the instrument cluster
come on. The indicator and warning
lamps (except high beam headlamp in-
dicator lamp and turn signal indicator
lamps if activated) should go out when
the engine is running. This indicates
that the respective systems are opera-
tional.
!If the SmartKey is left in the starter
switch position0 for an extended peri-
od of time, it can no longer be turned in
the starter switch.
Remove the SmartKey from the
starter switch and reinsert.
If the SmartKey can still not be turned
in the starter switch, the starter battery
may not be sufficiently charged.
Have the starter battery checked
and charged if necessary
(page 358). Contact an autho-
rized Mercedes-Benz Center.
To prevent accelerated battery
discharge and a possible dead battery,
always remove the SmartKey from the
starter switch when the engine is not in
operation.
