COLD WEATHER DRIVING 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. For details, see ''Changing engine coolant'' in the ''Maintenance and do-it-yourself'' section of this manual. WARNING ● The traction control system is designed to help improve driving stability but does not prevent accidents due to abrupt steering operation at high speeds or by careless or dangerous driving techniques. Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive carefully. ● If suspension parts such as shock absorbers, struts, springs and bushings are not standard equipment or are extremely deteriorated, the traction control off indicator light may come on. ● When driving on extremely inclined surfaces such as higher banked corners, the traction control system may not operate properly or the indicator light may come on. Do not drive on these types of roads. ● If tires other than the recommended ones are used, the traction control system may not operate properly or the indicator light may come on. ● The traction control system is not a substitute for winter tires or tire chains on a snow covered road. 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. 3. Tire chains may be used. Use of tire chains may be prohibited according to location. Check the local laws before installing tire chains. When installing tire chains, make sure they are of proper size for 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. 5-20 Starting and driving
