•Position the jack according to the
following guides and turn the jack
handle clockwise until the wheel
is completely off the ground.
To lessen risk of personal
injury, do not put any part
of your body under the vehicle
while changing a tire. Do not start
the engine when your vehicle is
on the jack. The jack is ONLY
meant for changing the tire.
•Never use the rear differential
as a jacking point.
8. Remove the lug nuts with the lug wrench.
9. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall lug nuts until the wheel is snug against the hub.
Do not fully tighten the lug nuts until the wheel has been lowered.
10. Lower the vehicle by turning the jack handle counterclockwise.
11. Remove the jack and fully
tighten the lug nuts in the order
shown.
12. Put flat tire, jack and lug wrench
away.

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.
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.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.

3. Connect the negative (-) cable to the negative (-) terminal of the
assisting battery.
4. Make the final connection of the negative (-) cable to an exposed
metal part of the stalled vehicle’s engine, away from the battery and the
carburetor/fuel injection system.Do notuse fuel lines, engine rocker
covers or the intake manifold asgroundingpoints.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
5. Ensure that the cables are clear of fan blades, belts, moving parts of
both engines, or any fuel delivery system parts.
Jump starting
1. Start the engine of the booster vehicle and run the engine at
moderately increased speed.
2. Start the engine of the disabled vehicle.

Engine oil and filter recommendations
Look for this certification
trademark.
Use SAE 5W-20 engine oil.
Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). To protect your engine’s warranty use
Motorcraft SAE 5W-20 or an equivalent 5W-20 oil meeting Ford
specification WSS-M2C153–H.SAE 5W-20 oil provides optimum fuel
economy and durability performance meeting all requirements for
your vehicle’s engine.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil according to the appropriate schedule listed in
the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 16 km (10 miles) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.

•The engine will completely shut down, causing steering and braking
effort to increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re-start the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
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.
