Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale
< will always illuminate for
6 seconds to remind you and your passen-
gers 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 pas-
senger’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.
