WINDSHIELD WASHER FLUID
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 specificationsin theCapacities and specifications
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.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.

Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
