When closing the moon roof, you should verify that it is free of
obstructions and ensure that children and/or pets are not in the
proximity of the moon roof opening.
AUXILIARY POWER POINT
Power outlets are designed for
accessory plugs only. Do not
hang any type of accessory or
accessory bracket from the plug.
Improper use of the power
outlet can cause damage not
covered by your warranty.
The auxiliary power point is located
on the instrument panel.
Do not plug optional electrical accessories into the cigarette lighter. Use
the power point.
Do not use the power point for operating the cigarette lighter element.
The Maximum power each power point can supply depends on the fuse
rating. For example: a 20A fuse should supply a maximum of 240 Watts,
a 15A fuse should supply a maximum of 180 Watts and a 10A fuse should
supply a maximum of 120 Watts. Exceeding these limits will result in a
blown fuse.
Always keep the power point caps closed when not being used.
POWER WINDOWS (IF EQUIPPED)
Do not leave children unattended in the vehicle and do not let
children play with the power windows. They may seriously injure
themselves.
When closing the power windows, you should verify they are free
of obstructions and ensure that children and/or pets are not in
the proximity of the window openings.

Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the air bag system, increasing
the risk of injury. Do not modify the front end of the vehicle.
Additional equipment such as snowplow equipment may effect
the performance of the air bag sensors increasing the risk of
injury. Please refer to theBody Builders Layout Bookfor instructions
about the appropriate installation of additional equipment.
Removing the blocker beam without installing snow plow
attachment hardware may effect air bag deployment in a crash.
Do not operate the truck unless either the blocker beam or snow plow
attachment hardware is installed on the vehicle.
Children and air bags
For additional important safety information, read all information on
safety restraints in this guide.
Children must always be properly restrained. Failure to follow these
instructions may increase the risk of injury in a collision.
An infant in a rear-facing seat faces a high risk of serious or fatal
injuries from a deploying passenger air bag. Rear facing infant
seats should NEVER be placed in the front seats, unless the passenger
air bag is turned off. SeePassenger air bag ON/OFF switch.

3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
Emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Understanding the gearshift positions of the 4–speed automatic
transmission (if equipped-gasoline engines only)
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
•Start the engine
•Depress the brake pedal
•Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)

•Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer
other than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the spare tire label for limitations
when using.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance Guide
for more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
•Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants any time the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.

certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Never remove or defeat the“tripping mechanisms”designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modify the air bag
supplemental restraint system (SRS) or its fuses. See your Ford
or Lincoln Mercury dealer.
Additional equipment such as snowplow equipment may effect
the performance of the air bag sensors increasing the risk of
injury. Please refer to theBody Builders Layout Bookfor instructions
about the appropriate installation of additional equipment.
Transmission operation while plowing
•Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 5 mph (8 km/h).
•Shift transfer case to 4x4 HIGH (4WD High) when plowing larger
areas or light snow at higher speeds. Do not exceed 15 mph (24
km/h).
•Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
•If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at normal operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.

This switch is located in the front
passenger’s footwell, behind the kick
panel access cover.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition ON.
5. Wait a few seconds and return
the key to OFF.
6. Make another check for leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
