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.
Roadside emergencies
140

When driving with the temporary spare tiredo not:
²exceed 80 km/h (50 mph) under any circumstances
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
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.
1. Park on a level surface, activate hazard flashers and set parking brake.
2. Place gearshift lever in P (Park) and turn engine OFF.
3. Remove the spare tire and the
jack and lug wrench which are
under the spare tire.
4. Locate pry off notch (if
equipped) and remove the center
ornament from the aluminum wheel
with the tapered end of the wheel
nut wrench that came with your
vehicle. Insert and twist the handle,
then pry against the wheel.
Roadside emergencies
141

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.
²Never 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 wheel 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.
13. Turn on 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.

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification Label. Make sure that all tires are the same size, speed
rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g., ªAll Terrainº, etc.),
as originally offered by Ford.
