CORROSION PROTECTION Floor mats The use of Genuine NISSAN floor mats can extend the life of your vehicle carpet and make it easier to clean the interior. No matter what mats are used, be sure they are fitted for your vehicle and are properly positioned in the footwell to prevent interference with pedal operation. Mats should be maintained with regular cleaning and replaced if they become excessively worn. Most common factors contributing to vehicle corrosion. 1. The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas. 2. Damage to paint and other protective coatings caused by gravel and stone chips or minor traffic accidents. Seat belts AAI1002 Environmental factors which influence the rate of corrosion. Moisture Accumulation of sand, dirt and water on the vehicle body underside can accelerate corrosion. Wet floor coverings will not dry completely inside the vehicle, and should be removed for drying to avoid floor panel corrosion. Relative humidity Corrosion will be accelerated: ● in areas of high relative humidity. ● in areas where the temperatures stay above freezing. ● where atmospheric pollution exists. ● where road salt is used. Appearance and care 7-5 Floor mat positioning aid (Driver's side only) This vehicle includes a front floor mat bracket to act as a floor mat positioning aid. NISSAN floor mats have been specially designed for your vehicle model. The driver's side floor mat has a grommet hole incorporated in it. Position the mat by placing the floor mat bracket hook through the floor mat grommet hole while centering the mat in the footwell. Periodically check to make certain the mats are properly positioned. The seat belts can be cleaned by wiping them with a sponge dampened in a mild soap solution. Allow the belts to dry completely before using them. WARNING Do not allow wet belts to roll up in the retractor. NEVER use bleach, dye, or chemical solvents since these may severely weaken the seat belt webbing.
