WINDSHIELD WIPER BLADES 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 fluid 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 fluid 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, install new windshield wiper blades. 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. ● 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. LDI2118 VQ35DE ● Wipe the inside of the air cleaner filter housing and the cover with a damp cloth. NOTE: After installing a new air cleaner, make sure the air cleaner cover is seated in the housing and latch the clips. IN-CABIN MICROFILTER 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 glove box. Refer to the "NISSAN Service and Maintenance Guide" for change intervals. If replacement is required, see your NISSAN dealer. CAUTION Worn windshield wiper blades can damage the windshield and impair driver vision. Maintenance and do-it-yourself 8-21
