WARNING ● If the light does not illuminate with the ignition switch turned ON, have the vehicle checked by a NISSAN dealer as soon as possible. ● If the light illuminates while driving, avoid sudden steering maneuvers or abrupt braking, reduce vehicle speed, pull off the road to a safe location and stop the vehicle as soon as possible. Serious vehicle damage could occur and may lead to an accident and could result in serious personal injury. Check the tire pressure for all four tires. Adjust the tire pressure to the recommended COLD tire pressure shown on the Tire and Loading Information label to turn the low tire pressure warning light OFF. If the light still illuminates while driving after adjusting the tire pressure, a tire may be flat. If you have a flat tire, replace it with a spare tire as soon as possible. ● When a spare tire is mounted or a wheel is replaced, tire pressure will not be indicated, the TPMS will not function and the low tire pressure warning light will flash. Contact your NISSAN dealer as soon as possible for tire replacement and/or system resetting. ● Replacing tires with those not originally specified by NISSAN could affect the proper operation of the TPMS. Seat belt warning light and chime The light and chime remind you to fasten your seat belts. The light illuminates whenever the ignition key is turned to the ON or START position and remains illuminated until the driver's seat belt is fastened. At the same time, the chime sounds for about 6 seconds unless the driver's seat belt is securely fastened. The seat belt warning light may also illuminate if the front passenger's seat belt is not fastened when the front passenger's seat is occupied (if so equipped). For 5 seconds after the ignition switch is in the ON position, the system does not activate the warning light for the front passenger. Refer to "Seat belts" in the "Safety-Seats, seat belts and supplemental restraint system" section for precautions on seat belt usage. CAUTION ● The TPMS is not a substitute for the regular tire pressure check. Be sure to check the tire pressure regularly. ● If the vehicle is being driven at speeds of less than 16 MPH (25 km/h), the TPMS may not operate correctly. ● Be sure to install the specified size of tires to the 4 wheels correctly.

See "Window washer fluid" in the "Maintenance and do-it-yourself" section of this manual.
