FORD F150 1997 10.G Owners Manual

Careless or high speed driving
while plowing snow which results
in vehicle decelerations equivalent
to or greater than the air bag
deployment impact speeds listed
above can deploy the air bag. Such
driving also increases the risk of
accidents.
All occupants of the
vehicle, including the
driver, should always wear their
safety belts.
Never remove or defeat the
ªtripping mechanismsº 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 or its fuses. See your
Ford or Lincoln-Mercury dealer.
Engine temperature while
plowing
When driving with a plow, your
engine may run at a higher
temperature than normal because
the attached snowplow blade will
restrict airflow to the radiator.

Driving
132

If you are driving more then 24 km
(15 miles) at temperatures above
freezing, angle the plow blade
either full left or full right to
provide maximum airflow to the
radiator.
If you are driving less than 24 km
(15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will
not need to worry about blade
position to provide maximum
airflow.
Transmission operation while
plowing
²Shift transfer case to 4L (4WD
Low) when plowing in small
areas at speeds below 8 km/h (5
mph).
²Shift transfer case to 4H (4WD
High) when plowing larger areas
or light snow at higher speeds.
Do not exceed 24 km/h (15
mph).
²Do not shift the transmission
from a forward gear to R
(Reverse) until the engine is at
idle and the wheels are stopped.
²If 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.
Driving
133

Do not spin the wheels at
over 35 mph (55 km/h).
The tires may fail and injure a
passenger or bystander.
FUEL CONSUMPTION
Fuel economy can be improved by
avoiding:
²lack of regular, scheduled
maintenance
²excessive speed
²rapid acceleration.

HAZARD LIGHTS CONTROL
Use only in an emergency to warn
traffic of vehicle breakdown,
approaching danger, etc. Depress
to activate all indicators
simultaneously. Depress again to
switch off. The warning lights can
be operated when the ignition is
off.
FUEL PUMP SHUT-OFF SWITCH
If the engine cranks but does not
start after a collision, the fuel
pump shut±off switch may have
been activated. The shut±off
switch is a device intended to stop
the electric fuel pump when your
vehicle has been involved in a
substantial jolt.
1. Turn the ignition switch to the
OFF position.
2. Check fuel system for leaks.
3. If no fuel leak is apparent, reset
the fuel pump shut-off switch by
pushing in the button on the
switch.
4. Turn the ignition switch to the
ON position. Pause for a few
seconds and return the key to the
OFF position.
5. Make a further check for leaks

REPLACING BLOWN FUSES
If electrical components in the
vehicle are not working, a fuse
may have blown. Blown fuses are
identified by a broken element.
Check the appropriate fuses before
replacing any electrical
components.
Even after a fuse is replaced, it
may continue to blow if the cause
of the overload is not identified
and corrected. If a fuse continues
to blow, have the vehicle's
electrical system checked.

Instrument panel fuses
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.
