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 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.
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 additional information, refer to “Changing engine coolant” in the “Maintenance and do-ityourself” section of this manual.
