COLD WEATHER DRIVING 10 inches (25.0 cm) from the side of the vehicle, the tone will sound for only 3 seconds. Once the system detects an object approaching, the tone will sound again. The Front Sonar System sounds a tone to warn the driver of obstacles near the front bumper. The front sonar system automatically turns on when the shift lever is placed in a forward gear and the ignition switch is in the ON position. The system may not detect objects at speeds above 3 MPH (5 km/h) and may not detect certain angular or moving objects. The Front Sonar System detects obstacles up to 3 feet (1.0 m) from the front bumper with a decreased coverage area at the outer corners of the bumper, (refer to the illustration for approximate zone coverage areas). As you move closer to the obstacle, the rate of the tone increases. When the obstacle is less than 10 inches (25.0 cm) away, the tone will sound continuously. If it detects a stationary or receding object further than 10 inches (25.0 cm) from the side of the vehicle, the tone will sound for only 3 seconds. Once the system detects an object approaching, the tone will sound again. The front and rear sonar system OFF switch on the instrument panel allows the driver to turn the sonar system on and off. To turn the system off, the ignition must be ON, and the shift lever in R (Reverse) or D (Drive). An indicator light on the switch will illuminate when the system is turned off. If the indicator light illuminates when the system is not turned off, it may indicate a failure in the sonar system. Keep the front and rear sonar sensors (located on the 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 sonar system. 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 or the NISSAN Intelligent Key®. ANTIFREEZE In the winter when it is anticipated that the temperature will drop below 32°F (0°C), check the antifreeze to assure proper winter protection. For additional information, refer to "Engine cooling system" in the "Maintenance and do-it-yourself" section of this manual. 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 additional information, refer to "Battery" in the "Maintenance and do-it-yourself" section of this manual.
