WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer toLubricant specifications
in this chapter.
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common
windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents
should be used only if they provide
cold weather protection without
damaging the vehicle’s paint finish,
wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5°C (40°F),
use washer fluid with antifreeze protection. Failure to use washer
fluid with antifreeze protection in cold weather could result in impaired
windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil

for checking the engine oil.
