Restraint System

Seat belts are the primary means of occupant restraint.

Seat belts help to keep the occupant inside the passenger compartment and to gradually reduce the crash forces during the following events:

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

All seat belts have emergency locks in the retractors. The retractors remain unlocked during normal operation. The retractors remain unlocked under normal driving conditions in order allow free movement of the upper body of the 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 actions occur:

    • 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 steep downgrade

This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System in addition to the seat belts. Refer to SIR in Restraints for more information.

Child Restraint

Caution: A child in a rear-facing child restraint can be seriously injured if the right-front passenger's air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. It is always better to secure a child restraint in the rear seat. If a forward-facing child seat 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 should be installed and secured according to the manufacturer's instructions.

The automatic locking (cinch) feature can be used in order to secure the child seat.

The child seat should be anchored if the child seat has a top strap. The kit for the rear center position is delivered in the glove box on all new vehicles which are first sold in Canada. The kits are available in the United States through GMSPO. Service instructions are included in the installation kit.
