Belt warning for driver and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the front passenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7 seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
