Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste, cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
CALIFORNIA Proposition 65 Warning
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
PERCHLORATE MATERIAL
Certain components of this vehicle such as airbag modules, seat belt
pretensioners, and button cell batteries may contain Perchlorate Material
– Special handling may apply for service or vehicle end of life disposal.
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer. For more detailed information about towing a trailer, refer to
Trailer towingin theTires, Wheels and Loadingchapter.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter for more information on oil
usage.
SPECIAL NOTICES

the service. Ford Motor Company and the vendors it uses to
provide you with this information do not store your vehicle travel
information. For more information, see Traffic, Directions and
Information, Terms and Conditions. See your SYNCsupplement
