The top of the fluid level is lower
than E (if equipped).
Use plain water if washer fluid is
unavailable.
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.
Body Lubrication
▼ Body Lubrication
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
non-freezing lubricant on locks during
cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when
the primary latch is released.
