System self-test
The 42 indicator lamp illuminates when you:
• turn the SmartKey to position 1 or 2 in the
ignition lock
• on vehicles with KEYLESS-GO, press the
Start/Stop button once or twice
The indicator lamp goes out again after approximately six seconds.
If the indicator lamp does not illuminate or is lit continuously, the system is malfunctioning. Have the BabySmart™ system checked at an authorized Mercedes- Benz Center before transporting a child on the front-passenger seat.
For further information, see "Problems with air bag deactivation system".
WARNING
Do not place powered-on laptops, mobile
phones, electronic tags such as those used in
skipasses or similar electronic devices on the
front passenger seat. Signals from such
devices may interfere with the BabySmart™
air bag deactivation system. Such signal
interference may cause the
indicator lamp not to come on during self-test.
The + SRS indicator lamp and/or the
indicator lamp could be
continuously lit, indicating that the system is
not functioning. The front-passenger front air
bag could deploy inadvertently or fail to
deploy in an accident.
