inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner's manual. Low pressure warning If the vehicle is being driven with very low tire pressure (lower than 28 psi, 193 kPa), the light will illuminate and the chime will sound for about 10 seconds. For additional information, see "Low tire pressure warning system" in the "Starting and driving" section and "Low tire pressure warning system" in the "In case of emergency" section. ● If the light comes on 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 placard to turn the low tire pressure warning light OFF. If the light still comes on 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 and the low tire pressure warning system will not function. Contact your NISSAN dealer as soon as possible for tire replacement and/or system resetting. CAUTION ● The low tire pressure warning system 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 20 MPH (32 km/h), the low tire pressure warning system may not operate correctly. ● Be sure to install the specified size of tires to the 4 wheels correctly. Low windshield washer fluid warning light (if so equipped) This light comes on when the windshield washer fluid is at a low level. Add windshield washer fluid as necessary. See the "Maintenance and do-ityourself" section of this manual. WARNING ● If the light does not come on with the key switch turned ON, have the vehicle checked by a NISSAN dealer as soon as possible. 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 7 seconds unless the driver's seat belt is securely fastened. 2-12 Instruments and controls
