Engine shield
Some vehicles may be equipped
with an aero-shield under the
engine. This shield needs to be
removed for service, including oil
and filter changes. It is secured with
four quick release fasteners.
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 specifications. Do not use any
special washer fluid such as
windshield water repellent type fluid
or bug wash. They may cause
squeaking, chatter noise, streaking
and smearing. Refer to
Maintenance product specifications and capacitiesin 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.
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), 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.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.
