Stowing the spare
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its original
position underneath the vehicle. The
jack handle ratchets when the tire is
raised to the stowed position. It will
not allow you to overtighten.
Tire change procedure
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then 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.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension switch prior to jacking, hoisting or towing your
vehicle.
Refer to the instruction sheet for detailed tire change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking

personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do

²Never use the front or rear
differential as a jacking point.

facing outward. Reinstall the lug nuts, cone side in, until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the wheel
has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.
11. Remove the jack and fully
tighten the lug nuts in the order
shown.
12. Stow the flat tire, jack and lug

The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Do not push start your vehicle. You could damage the catalytic
converter.
Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push start your vehicle. Automatic
transmissions do not have push-start capability.
Preparing your vehicle
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.

disabled vehicle's battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.
If equipped with air suspension, the air suspension control must be
turned to the OFF position.
The Ford approved towing procedure is flatbed or wheel lift with
dollies.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift or flatbed equipment with all the wheels off the ground.
