Never allow anyone to ride in the cargo area while the vehicle is in motion. It does not contain seat belts. It is not designed for passengers. They could be injured in sudden braking or a collision. If the seat belt warning light glows continuously while the ignition is turned ON with all doors closed and all seat belts fastened, it may indicate a malfunction in the system. Have the system checked by an authorized NISSAN dealer. All seat belt assemblies including retractors and attaching hardware should be inspected by an authorized NISSAN dealer after any collision. NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Seat belt assemblies not in use during a collision should also be inspected and replaced if either damage or improper operation is noted. Pre-tensioner seat belt system (For front seats) WARNING The pre-tensioner seat belt cannot be reused after activation. It must be replaced together with the retractor and buckle as a unit. If the vehicle becomes involved in a frontal collision but the pretensioner is not activated, be sure to have the pre-tensioner system checked and, if necessary, replaced by your NISSAN dealer. No unauthorized changes should be made to any components or wiring of the pre-tensioner seat belt system. This is to prevent accidental activation of the pre-tensioner seat belt or damage to the pre-tensioner seat belt operation. Tampering with the pre-tensioner seat belt system may result in serious personal injury. Work around and on the pretensioner system should be done by an authorized NISSAN dealer. ARS1103 Be sure the seat belt tongue is securely fastened to the proper buckle. Do not wear the seat belt inside out or twisted. Doing so may reduce its effectiveness. Do not allow more than one person to use the same seat belt. Never carry more people in the vehicle than there are seat belts. 1-14 Seats, restraints and supplemental air bag systems
