Removing the spare tire and jack
1. Lift the carpeted load floor panel
located in the rear of the vehicle.
2. Remove the spare tire cover (if
equipped).
3. Remove the wing nut securing
the spare tire by turning it
counterclockwise.
4. Lift and remove the temporary
spare tire from the cargo area.
5. Remove the jack assembly from
the vehicle. Loosen the bag tabs and
remove the jack and lug wrench
from the bag.
6. Fold down the wrench socket
used to loosen the lug nuts and
operate the jack.
Tire change procedure
When one of the front wheels is off the ground, the transaxle
alone will not prevent the vehicle from moving or slipping off the
jack, even if the vehicle is in P (Park).
To help prevent the vehicle from moving when you change a tire,
be sure to place the transaxle in P (Park), 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.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

Stowing the flat/spare tire and jack
1. Fully collapse the jack, fold the wrench socket into the handle and
place them both into the bag making sure to secure the tabs.
2. Place the jack assembly in the spare tire well aligning it with the two
vertical studs.
3. Place the tire in the spare tire well over the jack assembly.
If you are stowing a flat tire,place the tire in the spare tire well with
the valve stem facing down. Rotate the tire until the jack assembly is
able to protrude through a wheel opening.
If you are stowing the spare tire,place the spare in the spare tire
well in its original position.
4. Secure the wheel by replacing the wing nut and turning clockwise.
WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque within 100 miles (160 km)
after any wheel disturbance (rotation, flat tire, wheel removal, etc.).
Lug nut socket
size/Bolt sizeWheel lug nut torque*
lb.ft. N•m
Lug nut socket size:
3 4
inch (19 mm) hex
Bolt size:1 2x20100 135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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. Ensure 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.

The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive vacuum in
the fuel tank may damage the fuel system or cause the fuel cap
to disengage in a collision, which may result in serious personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Gasoline may contain benzene, which is a cancer-causing agent.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials
and any open flames before
refueling your vehicle.
•Always turn off the vehicle before
refueling.
•Automotive fuels can be harmful
or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.

Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/4 turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until at least a few clicks are
heard.
If the check fuel cap light
or a “check fuel cap” message comes on,
the fuel filler cap may not be properly installed. The light or message can
come on after several driving events after you’ve refueled your vehicle.
At the next opportunity, safely pull off of the road, remove the fuel filler
cap, align the cap properly and reinstall it. The check fuel cap
light
or “check fuel cap” message may not reset immediately; it may
take several driving cycles for the check fuel cap light
or “check fuel
cap” message to turn off. A driving cycle consists of an engine start-up
(after four or more hours with the engine off) followed by city and
highway driving.
Continuing to drive with the check fuel cap light
or “check fuel cap”
message on may cause the
light to turn on as well.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford, Motorcraft or other certified fuel filler cap
is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive vacuum in
the fuel tank may damage the fuel system or cause the fuel cap
to disengage in a collision, which may result in personal injury.

To reduce the risk of vehicle damage and/or personal burn
injuries do not start your engine with the air cleaner removed
and do not remove it while the engine is running.
Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter element edges between the air filter
housing and cover. This could cause filter damage and allow unfiltered
air to enter the engine if not properly seated.
6. Replace the air filter housing
cover and secure the clamps. Be
sure that the air cleaner cover tabs
are engaged into the slots of the air
cleaner housing.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
