73 Safety and Security
Occupant safety
Occupant Classification System
The O
ccupant C
lassification S
ystem (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
nearly upright position with their back
against the seat backrest and feet on the
floor to be correctly classified. If the occu-
pant's weight is transferred to another
object in the vehicle (e.g. by leaning on
armrests), the OCS may not be able to
properly approximate the occupant’s
weight category.
Warning!
G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
iThe system does not deactivate the
front passenger side impact air bag,
the window curtain air bag and the
emergency tensioning device.
