Ifyou use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing you to lose
control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tiredo not:
•use more than one temporary spare tire at a time
•exceed 80 km/h (50 mph) or drive further than 3
200 km (2 000 miles) total under any
circumstances
•load the vehicle beyond maximum vehicle load
rating listed on the tire pressure label on the
inside of the glove compartment door
•tow a trailer
•use tire chains
•drive through an automatic car wash, because of
the vehicle’s reduced ground clearance
•try to repair the temporary spare tire or remove it
from its wheel
•use the wheel for any other type of vehicle
Use of a temporary spare tire at any one wheel
location can lead to impairment of the following:
•handling, stability and braking performance
•comfort and noise
•ground clearance and parking at curbs
•Winter driving capability
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.

5. Put the jack in the
jack notch next to the
tire you are changing.
Turn the jack handle
clockwise until the
wheel is completely off
the ground.
Never use the rear
differential as a
jacking point.
To lessen the
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.
6. Remove the lug nuts with the lug wrench.
7. 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.
If you are using the temporary tire, the lug nut
washers will not appear to be flush with the rim.
This is normal only when using the temporary spare
tire.
8. Lower the wheel by turning the jack handle
counterclockwise.

9. Remove the jack and
fully tighten the lug
nuts in the order
shown.
10. Put flat tire, wheel
ornament (if
equipped), jack and lug
wrench away. Make
sure jack is fastened so it does not rattle when you
drive.
11. Unblock the wheels.
Anti-theft lug nuts (if equipped)
If your vehicle is equipped with this feature, one of
the lug nuts on each wheel must be removed and
replaced with a special key. The key and registration
card are attached to the lug wrench and stored with
the spare tire. If you lose the key, send the
registration card to the manufacturer (not the
dealer) to get a replacement key. If the lug
wrench/lug nut key assembly is lost, see your
nearest Ford or Lincoln Mercury dealer who has
access to the master set of keys.Do not use an
impact wrench with the anti-theft key.
To remove the
anti-theft lug nut:
1. Insert the key over
the locking lug nut.
Make sure you hold the key square to the lug nut. If
you hold the key at an angle, you could damage the
key and the lug nut.
2. Place the lug nut wrench over the lug nut key and
apply pressure on the key with the wrench.
3. Turn the wrench in a counterclockwise direction
to remove the lug nut.
To install the anti-theft lug nut:
1. Insert the key over the locking lug nut.
2. Place the lug nut wrench over the lug nut key and
apply pressure on the key with the wrench.1

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 the 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. 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. 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.
When the battery is disconnected or a new battery
installed, the transmission must relearn its adaptive
strategy. As a result of this, the transmission may
shift firmly. 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 to
its optimum shift feel.
If the battery has been disconnected or a new
battery has been installed, the clock and the preset
radio stations must be reset once the battery is
reconnected.
•Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
recycling center to find out more about recycling
automotive batteries.
