Seat Belts (cont'd)
Driver's Belt Unlatched — The warning lights will come on if
the driver's seat belt is not latched. The beeper will sound for
approximately six seconds while the light is ON, Relatch the belt;
the light should go off.
Front Passenger's Belt Unlatched — The warning light will
come on if the passenger's belt is not securely latched, the beeper
will sound for approximately six seconds. Relatch the belt; the light
should go off.
If the lights and beeper do not function at all or if they come on
even with the belts latched and doors fully closed, it indicates a
malfunction in the seat belt system. In the event of a collision,
severe personal injury could result. The system should be checked
immediately by an authorized Honda dealer.
Child Restraint
Children riding in the car should be restrained to minimize the risk of
injury in an accident, sudden stop or sudden maneuver.
According to accident statistics provided to the National Highway
Traffic Safety Administration (NHTSA), children are safer when
properly restrained in the rear seating positions than in the front
seat Larger children should use one of the seat belts provided.
For smaller children, we strongly recommend the use of a
commercially available child restraint system that meets the Federal
Motor Vehicle Safety Standard (FMVSS) because it offers the most
protection against injury. All states now have laws which require
that small children must be seated in a child passenger seat restraint
system. Check local laws.
Before buying a particular child restraint system, make sure it fits
your car seat and seat belts, and fits your child. Follow all the
instructions that come with the system.
