TRANSPORTING THE VEHICLE
WARNING
To reduce the risk of personal injury
or property damage when manually
releasing the spring brakes, block the
wheels so the vehicle cannot move when
you release the brakes. If you need to have your vehicle towed,
contact a professional towing service or,
if you are a member of a roadside
assistance program, your roadside
assistance service provider. We recommend the use of a wheel lift and
dollies or flatbed equipment to tow your
vehicle. Do not tow with a slingbelt. Ford
Motor Company has not approved a
slingbelt towing procedure. Vehicle
damage may occur if towed incorrectly, or
by any other means.
Ford Motor Company produces a towing
manual for all authorized tow truck
operators. Have your tow truck operator
refer to this manual for proper hook-up
and towing procedures for your vehicle.
It is acceptable to have your two-wheel
drive vehicle towed with the front wheels
on the ground (without dollies) and the
rear wheels off the ground.
We recommend towing a four-wheel drive
vehicle with all wheels off the ground, such
as using a wheel lift and dollies or flatbed
equipment. However, it is acceptable to
use a wheel lift to raise the rear of your
vehicle so long as, depending on vehicle
configuration, you perform the following
before towing:
•
If your vehicle is equipped with a
manual-shift transfer case, make sure
the front wheel hub locks are in the
FREE position before towing.
• If your vehicle is equipped with an
electronic shift-on-the-fly transfer
case, make sure you turn the
four-wheel drive control to the
2H
position before towing.
Note: Towing an electronic shift-on-the-fly
four-wheel drive vehicle with the front
wheels on the ground without disengaging
the front hubs may cause damage to the
automatic transmission.
Note: Towing a two-wheel drive vehicle or
an electronic shift-on-the-fly four-wheel
drive vehicle with the rear wheels on the
ground for more than 50 miles (80 km) or
faster than 35 mph (56 km/h) may cause
damage to the automatic transmission.

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm)
Belts (fan, alternator,
water pump and air
conditioning
compressor)
Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine.
Fluid leaks
Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance.
HVAC air inlet Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equipped
with spare electrical fuses (if used), three red reflective
triangles, a properly charged and rated fire extinguisher and
wheel chocks.
Safety and emergency
equipment
Walk around the vehicle and verify all steps and grab handles,
inside and out (as well as behind), are tight and clean. Use
extreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is in
neutral (N) or park (P) (if equipped with a park position).
Starting the engine
Diesel engine:
Turn the key to the on position. Turn the key
to start when the wait to start indicator light in the instrument
cluster turns off.
Gasoline engine:
Turn the key to start, and then release it
as soon as the engine starts.
Verify pressure builds to normal operating range.
Engine oil pressure
A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches
70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115– 130 psi (793–896 kPa)
.
Low air pressure warning
tone (if equipped with an
air compressor)
Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately.

Quality service parts are available through
an authorized dealer. If dealer parts are not
used, make sure the replacement parts are
of equivalent quality.
Working with the Engine Off
1. Set the parking brake and shift to
neutral (N) or park (P).
2. Switch off the engine.
3. Block the wheels.
Working with the Engine On WARNING
To reduce the risk of vehicle damage
and/or personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. 1. Set the parking brake and shift to
neutral (N) or park (P).
2. Block the wheels
Supporting Your Vehicle for
Service WARNING
Do not use a jack when working
under a vehicle. It may give way,
causing the vehicle to fall and result
in property damage, personal injury or
death. Always use floor stands to support
the vehicle. Prepare your vehicle for service repairs by
doing the following:
1. Park your vehicle on a level, concrete
floor.
2. Set the parking brake and block the wheels to prevent your vehicle from
moving. 3. Select a jack with a rated capacity
sufficient to lift and hold up your
vehicle.
4. Raise your vehicle with the jack applied
to the axle(s). Do not use the bumper
as a lifting point.
5. Support your vehicle with floor stands under the axle(s). When servicing the
axle or the suspension, support your
vehicle with floor stands under the
frame side-members, preferably
between the axles.
OPENING AND CLOSING THE
HOOD WARNINGS
Always set the parking brake fully
before opening the hood. Failure to
follow this warning could result in
serious personal injury or death. Do not stand under the hood when
you raise or lower it. Failure to follow
this warning could result in serious
personal injury or death. If the engine is running while the
hood is open, stay clear of moving
engine components. Failure to follow
this warning could result in serious
personal injury or death. Opening the Hood
Before opening the hood, set the parking
brake fully, shift into park (P) or neutral
(N) and switch the ignition off.
