    • The front seat belt system includes a driver and/or passenger seat belt retractor and buckle.
    •  The driver's seat belt system, includes a seat belt switch in the driver seat buckle which controls a reminder lamp and a tone alarm. When the driver seat belt is buckled, the driver's door is closed, and the ignition switch is turned ON, the following events will occur:
       - The tone alarm will not operate.
       - The reminder lamp will not operate.
    • When the driver's seat belt is not buckled, the driver's door is closed, and the ignition switch is in RUN, the following events will occur:
       -  The tone alarm will operate for 4 to 8 seconds and then go OFF.
       - The reminder lamp will operate for 20 seconds, or until the driver seat belt is buckled.

Rear Seat Belt System

The rear seat belt system includes the following components:

    • The rear seat belt retractor is located under the rear shelf trim panel and is attached to the rear shelf body panel.
    • The center rear seat belt buckle and the outer seat belt buckle are located in the center of the seat cushion and they are attached to the rear floor pan.

Child Seat Restraint System

Caution: A child in a rear-facing child restraint can be seriously injured if the right-front passengers air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. NEVER use a rear-facing child restraint in this vehicle. If a forward-facing child restraint is suitable for your child, ALWAYS move the front passenger seat as far back as it will go and then install the child restraint. Be sure the child restraint position does not conflict with any additional requirements provided by the manufacturer. For more information, refer to the vehicle owners manual and the instruction that came with the child restraint.

The child seat may only be used in a forward facing seating location. The child seat should be installed and secured according to the manufacturer's directions. If the child seat has a top strap, the seat will need to be anchored. Passengers should not be allowed to sit at locations where the seat belts are being used to secure the child seat.

All vehicles are equipped with a dual-mode type retractor with emergency and automatic locking features. The automatic locking feature is for restraint of a child seat. The child seat can be secured by pulling the seat belt all the way out to lock it. Then, tighten the seat belt around the child seat.

If a child seat is to be used in the second seat position, a special dealer-installed anchor must be used in order to anchor the child seat top strap. (This only applies to the seats designed with the top strap provision and for the vehicles sold in Canada). In order to ensure the correct top strap angle, the child seat is only to be used at the seating position for which the top strap anchor is installed.

The Body Control Module (BCM) receives a discrete input from the driver seat belt switch. The driver seat switch is opened when the seat belt is unbuckle.

Fasten Safety Belt Indicator (ISO Symbol) (Red)

The fasten safety belt indicator may only be ON during RUN. The BCM illuminates the fasten safety belt indicator under the following conditions:

    • During the bulb check.
    • The BCM sends the status of the driver's seat belt switch to the IPC. If the seat belt is unfastened, the IPC will illuminate the fasten safety belt indicator for 20 seconds or until the seat belt is fastened. If the seat belt is unfastened within 8 seconds following the bulb check the warning tone alarm will sound.
