Restraint System

NOTE: If the vehicle has been in a collision, refer to Repairs and Inspections Required After a Collision for additional information.

The vehicle has front and rear seat belts that are the primary means of occupant restraint. Seat belts help to keep the occupants inside the passenger compartment and to gradually reduce the impact forces during the following events:

  • Frontal impact type crashes
  • Rear impact type crashes
  • Side impact type crashes
  • Roll-over type crashes

All seat belt retractors have emergency locks. The retractors remain unlocked during normal operation and under normal driving conditions. The retractors remain unlocked during normal conditions in order to allow free movement of the upper body of each occupant. A pendulum locks the seat belt webbing into position. The pendulum causes a locking bar to engage a cog on the spool of the retractor mechanism when the following conditions occur:

  • A rapid extraction of the seat belt webbing from the retractor
  • An abrupt change in vehicle speed
  • An abrupt change in vehicle direction
  • Operation of the vehicle on a steep upgrade
  • Operation of the vehicle on a downgrade

The seat belts have an automatic locking (cinch) feature. The cinch feature is activated when the seat belt webbing is completely extended from the retractor. The cinch feature prevents the webbing from extending beyond the position from which it is allowed to retract. Use of the cinch feature is recommended for securing a child seat. The cinch feature may be cancelled by allowing the webbing to wind back completely into the retractor. After the cinch feature is cancelled, the webbing is unlocked.

After the cinch feature is cancelled, the webbing will extend from the retractor. This vehicle is also equipped with a supplemental inflatable restraint (SIR) system. Refer to Supplemental Inflatable Restraint System Description and Operation.

Front Seat Belt System

The front seat belt system includes a driver and passenger seat belt pretensioner anchor and retractor.

The front seat belt buckles include a seat belt switch which controls a reminder lamp.

NOTE: The front passenger seat is equipped with a passenger presence detection sensor, which detects an occupant. If the passenger presence detection sensor detects an empty front passenger seat, then the passenger fasten safety belt indicator will be disabled.

  • When the driver seat belt is buckled and the ignition switch is turned ON, the reminder lamp will not operate.
  • When the passenger seat belt is buckled with an occupant sitting in the passenger front seat, then the ignition switch is turned ON, the reminder lamp, which is located within the hazard warning switch, will not be turned ON.
  • When the driver seat belt is not buckled and the ignition switch is in the ON position, the fasten safety belt indicator will turn ON until the driver seat belt is buckled.
  • When the passenger seat belt is not buckled with an occupant sitting in the passenger front seat, then the ignition switch is turned ON, the passenger fasten safety belt indicator, which is located within the hazard warning switch, will turn ON until the passenger seat belt is buckled.

Rear Seat Belt System

The Rear Seat Belt System includes the following components:

  • The rear seat belt retractor is located at the wheelhouse panel and attached to the floor panel by the rear seat shoulder belt retractor bracket.
  • The rear seat belt buckles and the center seat belt buckle are attached to each seat.

Child Seat Restraint System

WARNING: A child in a rear-facing child restraint can be seriously injured if the front passenger air bag inflates, because the back of a rear-facing child restraint would be very close to the inflating air bag. NEVER use a rearfacing 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 owner's manual and the instructions 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.

Fasten Safety Belt Indicators

There are 2 fasten safety belt indicators for this vehicle. The driver fasten safety belt reminder is monitored on the instrument cluster and the passenger fasten safety belt reminder is located in the hazard warning switch. The fasten safety belt indicators may only be ON during RUN.

The instrument cluster illuminates the driver fasten safety belt indicator under the following conditions:

  • During the bulb check (will flash 20 times and then stay on solid until the driver seat belt is buckled).
  • The inflatable restraint sensing and diagnostic module (SDM) sends the status of the driver seat belt to the instrument cluster via a serial data.

The hazard warning switch illuminates the passenger fasten safety belt indicator under the following conditions:

Passenger presence recognizes someone is sitting in the front passenger seat. The SDM controls passenger seat belt indicator in the hazard warning switch through a hard wire circuit. The passenger seat belt indicator will remain on until the passenger seat belt is buckled.
