Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Malfunction and indicator lamps Seat belt nonusage warning lamp With the electronic key in starter switch position 2, the seat belt nonusage warning lamp comes on, and a warning sounds for a short time if the driver's seat belt is not fastened. After starting the engine, the seat belt nonusage warning lamp blinks for a brief period to remind the driver and passengers to fasten seat belts. Malfunction and indicator lamp in the center console AIRBAG OFF indicator lamp The 7 indicator lamp will light up for approximately 6 seconds when you turn the electronic key in starter switch to position 1 or 2. It does not light up if there is a fault in the system. The 7 indicator lamp stays lit as long as a BabySmartTM child seat is properly installed on the front passenger seat. It indicates that the front passenger airbag is switched off. See page 88 for BabySmartTM airbag and its deactivation system. 308 Warning! The BabySmartTM airbag deactivation system will ONLY work with a special child seat designed to operate with it. It will not work with child seats which are not BabySmartTM compatible. Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the deactivation system. Follow the manufacturer's instructions for installation of special child seats. The passenger front airbag will not deploy only if the 7 indicator lamp remains illuminated. Please be sure to check the indicator every time you use the special system child seat. Should the light go out while the restraint is installed, please check installation. If the light remains out, do not use the BabySmartTM restraint to transport children on the front passenger seat until the system has been repaired.
