CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Temporary spare tire information
Your vehicle may have a temporary or full-size spare tire. The temporary
spare tire for your vehicle is labeled as such. It is smaller than a regular
tire and is designed for emergency use only. Replace this tire with a
full-size tire as soon as possible.
If you 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:
²exceed 80 km/h (50 mph) under any circumstances
Roadside emergencies
100

²load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²tow a trailer
²use tire chains
²drive through an automatic car wash, because of the vehicle's reduced
ground clearance
²try to repair the temporary spare tire or remove it from its wheel
²use the wheel for any other type of vehicle
If the mini-spare tire is used as a replacement for a rear wheel:
²Turn off the traction control switch (if equipped).
²Turn off the air suspension switch (if equipped).
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.
Removing 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.
Reinstalling 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.
3. Install the lug nut.

battery to a 24±volt power supply you can damage your starter, ignition
system and other electrical components.
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 theydo 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.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Position the vehicles so that they
do not touch one another.
2. Switch off the engine. Switch off
any unnecessary electrical
equipment.
3. Connect the positive (+) terminal
of the discharged battery (1) to the
positive (+) terminal of the booster
battery (2).
4. Connect one end of the second
lead to the negative (-) terminal of
the booster battery (3) and the
other end to a metal part of the
engine to be started (4), not to the
negative (-) terminal of the discharged battery.
5. Make sure that the jump leads are clear of moving parts of the engine.
Do not connect the end of the second cable to the negative (-)
