Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer 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®.

temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection...
For USA
If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform the National
Highway Traffic Safety Administration
(NHTSA) in addition to notifying
NISSAN.
If NHTSA receives similar complaints,
it may open an investigation, and if it
finds that a safety defect exists in a
group of vehicles, it may order a recall
and remedy campaign...
