Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the
instrument cluster is a reminder for all
occupants to fasten their seat belts.
Regardless of whether the driver and front-
passenger seat belts have already been
fastened, the 7 seat belt warning lamp will
always illuminate for six seconds each time
the engine is started. It then goes out if the
driver and the front passenger have fastened
their seat belts.
If the driver or front-passenger seat belt is not
fastened when the engine is started, an
additional warning tone will sound. This
warning tone ceases after a maximum of six
seconds or when the driver and front
passenger have fastened their seat belts.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R the 7 seat belt warning lamp remains
illuminated as long as either the driver's or
front-passenger seat belt is not fastened.
R the 7 seat belt warning lamp lights up
if the vehicle speed exceeds 15 mph
( 25 km/h). Additionally, a warning tone will
sound with increasing intensity for a
maximum of 60 seconds or until the
driver's or front-passenger seat belt are
fastened.
If the driver or front passenger unfasten their
seat belt while the vehicle is in motion, the
7 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front passenger have still not fastened their
seat belt after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h) .
The 7 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.
