3. Use the lug nut wrench to screw the lug nut snugly against the wheel.
4. Lower the vehicle by turning the jack handle counterclockwise.
5. Remove the jack and fully tighten the lug nuts in the following
pattern:
•5-lug wheel
•8-lug wheel
Never use wheels or lug
nuts different than the
original equipment as this could
damage the wheel or mounting
system. This damage could allow
the wheels to come off while the
vehicle is being driven.
6. Install any wheel covers, ornaments or hub caps. Make sure they are
screwed or snapped in place.
7. Stow the jack, handle and lug wrench.
8. Unblock the wheels.
On vehicles equipped with single rear wheels, retighten the lug nuts to
the specified torque at 800 km (500 miles) of operation after any wheel
change or any time the lug nuts are loosened.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 160 km (100 miles), and again at 800 km
(500 miles) of new vehicle operation.

Note). Use only Ford recommended replacement fasteners.

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
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; also, the catalytic converter may
become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
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.
