COLD WEATHER DRIVING ● The system is designed as an aid to the driver in detecting large stationary objects to help avoid damaging the vehicle. The system will not detect small objects below the bumper, and may not detect objects close to the bumper or on the ground. ● If your vehicle sustains damage to the rear bumper fascia, leaving it misaligned or bent, the sensing zone may be altered causing inaccurate measurement of obstacles or false alarms. The Rear Sonar System (RSS) sounds a tone to warn the driver of obstacles near the rear bumper when R (Reverse) is selected. The system may not detect objects at speeds above 3 mph (5 km/h) and may not detect certain angular or moving objects. The RSS detects obstacles up to 6 ft. (1.8 meters) from the rear 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 in. (25.0 cm) away, the tone will sound continuously. If the RSS detects a stationary or receding object further than 10 in. (25.0 cm) from the side of the vehicle, the tone will sound for only three seconds. Once the system detects an object approaching, the tone will sound again. The RSS automatically turns on when the gear selector is placed in R (Reverse) and the ignition is ON. The RSS OFF switch on the instrument panel allows the driver to turn the RSS on and off. To turn the RSS off, the ignition must be ON, and the gear selector in R (Reverse). An indicator light on the switch will illuminate when the system is turned off. If the indicator light illuminates when the RSS is not turned off, it may indicate a failure in the RSS. Keep the RSS sensors (located on the rear 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 RSS. 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. 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. 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. 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. Starting and driving 5-31
