WINDSHIELD WIPER BLADES ● Never pour fuel into the throttle body or attempt to start the engine with the air cleaner removed. Doing so could result in serious injury. CLEANING If your windshield is not clear after using the windshield washer or if a wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with a washer solution or a mild detergent. Your windshield is clean if beads do not form when rinsing with clear water. Clean each blade by wiping it with a cloth soaked in a washer solution or a mild detergent. Then rinse the blades with clear water. If your windshield is still not clear after cleaning the blades and using the wiper, replace the blades. IN-CABIN MICROFILTER (if so equipped) The in-cabin microfilter restricts the entry of airborne dust and pollen particles and reduces some objectionable outside odors. The filter is located behind the trim panel near the accelerator pedal. Refer to the "NISSAN Service and Maintenance Guide" for change intervals. WDI0596 Type B If replacement is required, see your NISSAN dealer. WARNING ● Operating the engine with the air cleaner removed can cause you or others to be burned. The air cleaner not only cleans the air, it stops the flame if the engine backfires. If it isn't there, and the engine backfires, you could be burned. Do not drive with the air cleaner removed, and be careful when working on the engine with the air cleaner removed. CAUTION Worn windshield wiper blades can damage the windshield and impair driver vision. Maintenance and do-it-yourself 8-19
