Inspect fluid level in the washer fluid

Use plain water if washer fluid is

But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.

All moving points of the body, such as
door and hood hinges and locks, should be
lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
