● Keep the passenger supplemental air bag ON/OFF switch turned ON unless a rear-facing child restraint must be used in the front seat, if children ages 1-12 must be placed in the front seat, or if the passenger has a medical condition, which, according to a physician, causes the air bag to pose a special risk of harm (the federal government criteria). If the switch is OFF, the air bag will not inflate in a collision as designed and the extra protection provided by the air bag may be lost. ● 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. Children ages 1-12 and persons with special medical conditions may also be at risk from an inflating air bag. ● 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 light is also illuminated, something may be wrong with the air bag system. Infants, children ages 1-12 or persons with special medical conditions should not use the front passenger seat until the system is checked by your NISSAN dealer. 1-14 Seats, restraints and supplemental air bag systems
