CAR PHONE OR CB RADIO ANTENNA The antenna cannot be shortened, but can be removed. When you need to remove the antenna, turn the antenna rod counterclockwise. To install the antenna rod, turn the antenna clockwise. Tighten the antenna rod to specification using a suitable tool such as an open-end wrench. The antenna rod tightening specification is 3.4 - 3.6 N·m (30 - 32 in-lb). Do not use pliers to tighten the antenna as they can leave marks on the antenna surface. The antenna rod cannot be hand tightened to the proper specification. When installing a CB, ham radio or car phone in your NISSAN, be sure to observe the following cautions, otherwise the new equipment may adversely affect the MFI (Multiport Fuel Injection) system and other electronic parts. ● Keep the antenna wire more than 8 in (20 cm) away from the Multiport Fuel Injection harness. Do not route the antenna wire next to any harness. ● Adjust the antenna standing-wave ratio as recommended by the manufacturer. ● Connect the ground wire from the CB radio chassis to the body. ● For details, consult a NISSAN dealer. WARNING ● A cellular telephone should not be used while driving so full attention may be given to vehicle operation. Some jurisdictions prohibit the use of cellular telephones while driving. ● If you must make a call while your vehicle is in motion, the hands free cellular phone operational mode (if so equipped) is highly recommended. Exercise extreme caution at all times so full attention may be given to vehicle operation. ● If a conversation in a moving vehicle requires you to take notes, pull off the road to a safe location and stop your vehicle before doing so. CAUTION Always properly tighten the antenna rod during installation or the antenna rod may break during vehicle operation. CAUTION ● Keep the antenna as far away as possible from the Engine Control Module (ECM). Heater, air conditioner and audio systems 4-17
