Seat belts
When the engine is started, the seat belt
telltale< illuminates for a maximum of
6 seconds and a warning chime sounds to
remind you and your passengers to fasten
your seat belts.
If after these 6 seconds, the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) are not fastened
with all doors closed,

and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt
telltale< remains illuminated for as
long as either the driver’s or front
passenger’s seat belt is not fastened.


and the vehicle speed exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
intensity until both the driver’s and
front passenger’s seat belt are fas-
tened, or for a maximum of 60 seconds
from the time the vehicle speed exceeded 15 mph (25 km/h) if either
the driver’s or front passenger’s seat
belt remains unfastened.
If the driver’s or front passenger’s seat
belt remains unfastened after
60 seconds, the seat belt telltale<
stops flashing and the warning chime
stops sounding. The seat belt
telltale< then continues to be illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt are
not fastened.
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.
For more information, see “Practical hints”
(
page 550).
Always wear your seat belt. All vehicle
occupants always need to have their seat
belts fastened and wear them properly.
Warning!
G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification System.
The bottom of the child seat must make full
contact with the passenger seat cushion. An
incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.
