GENERAL MAINTENANCE During the normal day-to-day operation of the vehicle, general maintenance should be performed regularly as prescribed in this section. If you detect any unusual sounds, vibrations or smells, be sure to check for the cause or have an authorized NISSAN dealer do it promptly. In addition, you should notify an authorized NISSAN dealer if you think that repairs are required. When performing any checks or maintenance work, closely observe the ''Maintenance precautions'' later in this section. Check carefully for damage, cuts or excessive wear. Wheel nuts* When checking the tires, make sure no wheel nuts are missing, and check for any loose wheel nuts. Tighten if necessary. Tire rotation* Tires should be rotated every 7,500 miles (12,000 km). Wheel alignment and balance If the vehicle should pull to either side while driving on a straight and level road, or if you detect uneven or abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at normal highway speeds, wheel balancing may be needed. ● For additional information regarding tires, refer to ''Important Tire Safety Information'' in the Warranty Information Booklet (US) or ''Tire Safety Information'' in the Warranty and Roadside Assistance Information booklet (Canada).
