the vehicle. Using the heater for
longer than three hours will not
harm the engine, so the heater can
be plugged in the night before
starting the vehicle.
To prevent electrical
shock, do not use your
heater with ungrounded
electrical systems or
two-pronged (cheater) adapters.
Guarding against exhaust
fumes
Although odorless and colorless,
carbon monoxide is present in
exhaust fumes. Take precautions
to avoid its dangerous effects.
If you ever smell exhaust
fumes of any kind inside
your vehicle, have your dealer
inspect and fix your vehicle
immediately. Do not drive if you
smell exhaust fumes. These
fumes are harmful and could kill
you.
Have the exhaust and body
ventilation systems checked
whenever:
²the vehicle is raised for service
²the sound of the exhaust system
changes
²the vehicle has been damaged in
a collision

that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Driving on hill or slope terrain
When driving on a hill, avoid
driving crosswise or turning on
steep slopes. You could lose
traction and slip sideways. Drive
straight up, straight down or avoid
the hill completely. Know the
conditions on the other side of a
hill before driving over the crest.
When climbing a steep hill, start in
a lower gear rather than
downshifting to a lower gear from
a higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of
stalling.

²Allow more room for stopping
with a trailer attached.
²Practice turning, stopping and
backing in an area before
starting on a trip to get the feel
of the vehicle/trailer
combination.
²When turning, drive slightly
beyond the normal turning point
so the trailer wheels will clear
curbs and other obstacles.
²When stopped in traffic for long
periods of time in hot weather,
place the automatic transmission
gearshift in P (Park) to increase
idle speed. This aids engine
cooling and air conditioner
efficiency.
²Vehicles with trailers should not
be parked on a grade. If you
must park on a grade, place
wheel chocks under the trailer's
wheels.
²After you have travelled about
80 km (50 miles), thoroughly
check your hitch, electrical
connections and trailer wheel
lug nuts.
Launching or retrieving a boat
When backing down a ramp during
boat launching or retrieval,
²Do not allow the static water
level to rise above the bottom
edge of the rear bumper and
²Do not allow waves to break
higher than 15 cm (six inches)
above the bottom edge of the
rear bumper.

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.

Oil filters
Ford production and aftermarket
(Motorcraft) oil filters are designed
for added engine protection and
long life. If a replacement oil filter
is used that does not meet Ford
material and design specifications,
startup engine noises or knock
may be experienced. It is
recommended that you use the
appropriate Motorcraft oil filter (or
another brand meeting Ford
specifications) for your engine
application.
Checking engine oil
Check the engine oil each time you
fuel your vehicle.
Check the engine oil level more
frequently if the vehicle is carrying
a heavy load, towing a trailer,
idling for extended periods (like
police, taxi or shuttle service
vehicles) or driven at high speeds
for extended periods of time.
To check the oil:
1. Make sure the vehicle is on level
ground. If the engine is warm, turn
the engine off and wait a few
minutes for the oil to drain into
the oil pan.
2. Set the parking brake and
ensure the gearshift is latched in P
(Park) (automatic transmission) or
1 (First) (manual transmission).
3. Open the hood. Protect yourself
from engine heat.
4. Locate and carefully remove the

the MAX line, engine damage or
high oil consumption may occur
and some oil must be removed
from the engine by a service
technician.
7. Put the dipstick back in and
ensure it is fully seated.
Adding engine oil
1. Check the engine oil.
2. If the oil level is below the MIN
line, then add engine oil.
3. Remove the yellow oil filler cap.
4. Use a funnel to add oil through
the opening.
Make sure you use a certified
engine oil of the preferred
viscosity.
5. Recheck the oil level. Make sure
that the oil level is not above the
MAX line on the dipstick.

CHECKING AND ADDING
ENGINE COOLANT
Adding engine coolant
Do not put engine coolant
in the container for the
windshield washer fluid.
If sprayed on the windshield,
engine coolant could make it
difficult to see through the
windshield.
When the engine is cool, add a
50/50 mixture of engine coolant
and water to the engine coolant
recovery reservoir ± DO NOT ADD
DIRECTLY TO THE RADIATOR.
Add straight water only in an
emergency, but you should replace
it with a 50/50 mixture of coolant
and distilled water as soon as
possible.
Check the coolant level in the
coolant recovery reservoir the next
few times you drive the vehicle. If
necessary, add enough of a 50/50
mixture of coolant and water to
bring the liquid level to the fill line
on the reservoir.
Never remove the coolant
recovery cap while the
engine is running or hot.
