< will always illuminate
for 6 seconds to remind you and your
passengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with front doors closed,
ț
the seat belt telltale
< remains illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt is not
fastened
ț
and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale
< starts flashing and a
warning chime sounds with increasing
intensity for a maximum of 60 seconds
or until the driver’s and the front
passenger’s seat belt are fastened
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale
<
stops flashing but continues to be illu-
minated.
The seat belt telltale
< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.
