2. Slide the wheel partiallyunder the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
3. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantlyand the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your dealer for
assistance at your earliest convenience.
4. Check that the tire lies flat against the frame and is properly
tightened. Tryto push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire mayresult in failure of the winch cable and loss of the tire.
5. Repeat this tightness check procedure when servicing the spare tire
pressure (everysix months, per scheduled maintenance guide), or at any
time that the spare tire is disturbed through service of other
components.
6. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key(if equipped) and jack handle.
JUMP STARTING YOUR VEHICLE
The gases around the batterycan explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injuryor
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 batteryis disconnected or a new batteryis installed, the
transmission must relearn its shift strategy. As a result, the transmission
mayhave firm and/or soft shifts. This operation is considered normal and
will not affect function or durabilityof the transmission. Over time, the
adaptive learning process will fullyupdate transmission operation.
Roadside Emergencies
168

•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA window sticker
Everynew vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
mayvarydepending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use onlythe specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed in your scheduled maintenance guide performed
according to the specified schedule.
The scheduled maintenance items listed in the scheduled maintenance
guide are essential to the life and performance of your vehicle and to its
emissions system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Companyparts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the “Service Engine Soon” light, charging system warning
light or the temperature warning light, fluid leaks, strange odors, smoke
or loss of engine power, could indicate that the emission control system
is not working properly.
