The rear door locks on four-door sedans are designed and are set so that the inside handles "free-wheel" when the locking button is pushed down into lock position. This prevents children from accidentally opening the rear doors. The feature can be changed by any Buick Dealer if it is not desired.

When lock is set for free-wheeling it is necessary to raise the lock button before either the inside or outside handles will open the door.

*THERMAL RELAY -There are no fuses in the headlamp, tail lamp, parking lamp or instrument lamp circuits.

Protection for these circuits is through a thermostatically controlled current limit relay attached to light switch. When the current load is too heavy, due to a short circuit, the relay opens and closes rapidly thus reducing current sufficiently to protect the wiring from damage. This action continues until the cause is eliminated.
