After the child restraint is removed and the seat belt is allowed to wind back into the retractor, the automatic locking mode (child restraint mode) is canceled; The seat belt only locks during a sudden stop or impact. REAR FACING INSTALLATION ON FRONT PASSENGER SEAT (Three-point type with retractor) WARNING ● Keep the passenger supplemental air bag ON/OFF switch turned ON unless a rear-facing child restraint is used in the front seat. If the switch is OFF the air bag will not inflate in a collision as designed. ● Be sure to turn the passenger supplemental air bag ON/OFF switch OFF when using a rear facing child restraint in the front passenger seat. If it is not OFF, the air bag may inflate in a collision. The force of the rapidly inflating air bag could cause serious injury or kill the child in the child restraint. See ''Passenger supplemental air bag ON/OFF switch and light'' earlier in this section. ● If the supplemental air bag warning light located in the instrument panel next to the speedometer comes on when the passenger supplemental air bag OFF indicator light is also illuminated, something may be wrong with the air bag system. Do not use a child restraint in the front passenger seat until the system is checked by your NISSAN dealer. ● The three-point belt in your vehicle is equipped with a locking mode retractor which must be used when installing a child restraint. ● Failure to use the retractor's locking mode will result in the child restraint not being properly secured. The restraint could tip over or otherwise be unsecured and cause injury to the child in a sudden stop or collision. 1-30 Seats, restraints and supplemental air bag systems
