● 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. Driving with under-inflated tires may permanently damage the tires and increase the likelihood of tire failure. 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 located in the driver's door opening 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, the TPMS will not function and the low tire pressure warning light will flash for approximately 1 minute. The light will remain on after 1 minute. 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. Power steering warning light WARNING ● If the engine is not running or is turned off while driving, the power assist for the steering will not work. Steering will be harder to operate. ● When the power steering warning light illuminates with the engine running, there will be no power assist for the steering. You will still have control of the vehicle, but the steering will be much harder to operate. Have the power steering system checked by a NISSAN dealer. When the ignition switch is in the ON position, the power steering warning light illuminates. After starting the engine, the power steering warning light turns off. This indicates that the electric power steering system is operational. If the power steering warning light illuminates while the engine is running, it may indicate the power steering system is not functioning properly and may need servicing. Have the hydraulic pump electric power steering system checked by a NISSAN dealer. See "Power steering system" in the "Starting and driving" section. 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.
