COLD WEATHER DRIVING 3 seconds. Once the system detects an object approaching, the tone will sound again. The FSS automatically turns on when the shift selector is placed in a forward gear and the ignition switch is ON. The front and rear sonar system off switch on the instrument panel allows the driver to turn the FSS on and off. To turn the FSS off, the ignition switch must be ON, and the shift selector in D (Drive). An indicator light on the switch will illuminate when the system is turned off. If the indicator light illuminates when the FSS is not turned off, it may indicate a malfunction in the FSS. Keep the FSS sensors (located on the front bumper fascia) free from snow, ice and large accumulations of dirt (do not clean the sensors with sharp objects). If the sensors are covered, it will affect the accuracy of the FSS. FREEING A FROZEN DOOR LOCK To prevent a door lock from freezing, apply deicer through the key hole. If the lock becomes frozen, heat the key before inserting it into the key hole, or use the remote keyless entry keyfob (if so equipped) or the NISSAN Intelligent Key™ (if so equipped). DRAINING OF COOLANT WATER If the vehicle is to be left outside without antifreeze, drain the cooling system, including the engine block. Refill before operating the vehicle. For details, see "Changing engine coolant" in the "Maintenance and do-it-yourself" section of this manual. ANTI-FREEZE In the winter when it is anticipated that the temperature will drop below 32°F (0°C), check the anti-freeze to assure proper winter protection. For details, see "Engine cooling system" in the "Maintenance and do-it-yourself" section of this manual. TIRE EQUIPMENT 1. SUMMER tires have a tread designed to provide superior performance on dry pavement. However, the performance of these tires will be substantially reduced in snowy and icy conditions. If you operate your vehicle on snowy or icy roads, NISSAN recommends the use of MUD & SNOW or ALL SEASON TIRES on all four wheels. Please consult a NISSAN dealer for the tire type, size, speed rating and availability information. 2. For additional traction on icy roads, studded tires may be used. However, some U.S. states and Canadian provinces prohibit their use. Check local, state and provincial laws before installing studded tires. Skid and traction capabilities of studded snow tires on wet or dry surfaces may be poorer than that of non-studded snow tires. BATTERY If the battery is not fully charged during extremely cold weather conditions, the battery fluid may freeze and damage the battery. To maintain maximum efficiency, the battery should be checked regularly. For details, see "Battery" in the "Maintenance and do-it-yourself" section of this manual. Starting and driving 5-35
