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 key fob or the NISSAN Intelligent Key.
Antifreeze
In the winter when it is anticipated that the temperature will drop below 32F (0C), check the antifreeze to assure proper winter protection. For additional information, refer to "Engine cooling system" in the "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 "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 "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. It is recommended that you visit 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. For additional information, refer to "Tire chains" in the "Do-ityourself" section of this manual.
Special winter equipment
It is recommended that the following items be carried in the vehicle during winter:
Driving on snow or ice
WARNING
Accelerate and slow down with care. If accelerating or downshifting too fast, the drive wheels will lose even more traction.
These may appear on an otherwise clear road in shaded areas. If a patch of ice is seen ahead, brake before reaching it. Try not to brake while on the ice, and avoid any sudden steering maneuvers.
Engine block heater (if so equipped)
Engine block heaters are used to assist with cold temperature starting.
The engine block heater should be used when the outside temperature is 20F (-7C) or lower.
WARNING
To use the engine block heater: 1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110- volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least two to four hours, depending on outside temperatures, to properly warm the engine coolant. Use an appropriate timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away from moving parts.
