Tire Change Procedure
WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission is in park (P).
WARNING: To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission in park (P), set
the parking brake and block (in both directions) the wheel that is
diagonally opposite (other side and end of the vehicle) to the tire being
changed.
WARNING: Never get underneath a vehicle that is supported
only by a jack. If the vehicle slips off the jack, you or someone
else could be seriously injured.

WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
WARNING: Always use the jack provided as original equipment
with your vehicle. If using a jack other than the one provided as
original equipment with your vehicle, make sure the jack capacity is
adequate for the vehicle weight, including any vehicle cargo or
modifications.
WARNING: Disable the power running boards before jacking,
lifting, or placing any object under the vehicle. Never place your
hand between the power running board and vehicle as extended power
running boards will retract when the doors are closed. Failure to follow
these instructions may result in personal injury.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
Park on a level surface, set the parking brake, and activate the hazard
flashers. Place the transmission in park (P) and turn the engine off.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make sure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and foreign material contamination should be inspected
immediately by a qualified expert, such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure.
Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary.
Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if
necessary.
Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag, safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as
necessary.
