confirming your vehicle is in neutral tow.
When finished towing with all four wheels
on the ground return the transfer case to
its 2H position:
1. With your vehicle still properly secured
to the tow vehicle, put the ignition in
the on position, but do not start the

Shift Delayed Pull Forward
displays in the instrument cluster, a transfer
case blockage is present. See resolving the
shift delayed pull forward message
instructions after this section.
5. Apply the parking brake and disconnect
the vehicle from the tow vehicle.
6. Release the parking brake, start the engine and shift the transmission to
drive (D) to make sure the transfer
case is out of neutral (N).
7. If the transfer case does not successfully shift out of neutral (N),
set the parking brake until you can have
your vehicle serviced. Resolving the
Shift Delayed Pull Forward
Message

HAZARD FLASHERS
Note:
The hazard flashers operate when
the ignition is in any position, or if the key is
not in the ignition. If used when the vehicle
is not running, the battery loses charge. As
a result, there may be insufficient power to
restart your vehicle. The flasher control is on the
instrument panel. Use your
hazard flashers when your
vehicle is creating a safety hazard for other
motorists.
• Press the flasher control and all front
and rear direction indicators flash.
• Press the button again to switch them
off. FUEL SHUTOFF WARNING: If your vehicle has been
involved in a crash, have the fuel system
checked. Failure to follow this instruction
could result in fire, personal injury or
death.
Note: When you try to restart your vehicle
after a fuel shutoff, the vehicle makes sure
that various systems are safe to restart.
Once the vehicle determines the systems
are safe, then the vehicle allows you to
restart.
Note: In the event that your vehicle does
not restart after your third attempt, contact
a qualified technician.
The fuel pump shutoff stops the flow of
fuel to the engine in the event of a
moderate to severe crash. Not every
impact causes a shutoff.
Should your vehicle shut off after a crash,
you may restart your vehicle.
If your vehicle has a key system:
1. Switch off the ignition.
2. Switch to start position.
3. Switch off the ignition.
4. Switch on the ignition to re-enable the
fuel pump.
5. If the vehicle does not start, repeat steps 1 through 4.
If your vehicle has a push button start
system:
1. Press START/STOP to switch off your
vehicle.
2. Press the brake pedal and START/STOP
to switch on your
vehicle.
3. Remove your foot from the brake pedal
and press
START/STOP to switch off
your vehicle.

4. Press the brake pedal and start your
vehicle.
5. Run the engine until it reaches normal operating temperature. While the
engine is warming up, complete the
following: Reset the clock. Reset the
power windows bounce-back feature.
See Windows and Mirrors (page 95).
Reset the radio station presets. See
Audio System
(page 488).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
negative battery cable to maintain battery
charge for quick starting.
Battery Management System
(If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some electrical systems to
protect the battery. Systems included are:
•
Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
displays to alert you that battery
protection actions are active. These
messages are only for notification that an
action is taking place, and not intended to
indicate an electrical problem or that the
battery requires replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
may temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
WASHER FLUID CHECK WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 441).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER - 6.2L/7.3L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed. CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass.

2. Release the wiper blade lock (A) and
separate the wiper blade from the

3. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.
• Replace wiper blades at least once per
year for optimum performance.
• You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
