includes information about the performance or status of various systems
and modules in the vehicle, such as engine, throttle, steering or brake
systems. In order to properly diagnose and service your vehicle, Ford
Motor Company, Ford of Canada, and service and repair facilities may
access vehicle diagnostic information through a direct connection to your
vehicle when diagnosing or servicing your vehicle.
Event Data Recording
Other modules in your vehicle — event data recorders — are capable of
collecting and storing data during a crash or near crash event. The
recorded information may assist in the investigation of such an event.
The modules may record information about both the vehicle and the
occupants, potentially including information such as:
•how various systems in your vehicle were operating;
•whether or not the driver and passenger seatbelts were buckled;
•how far (if at all) the driver was depressing the accelerator and/or the
brake pedal;
•how fast the vehicle was traveling; and
•where the driver was positioning the steering wheel.
To access this information, special equipment must be directly connected
to the recording modules. Ford Motor Company and Ford of Canada do
not access event data recorder information without obtaining consent,
unless pursuant to court order or where required by law enforcement,
other government authorities or other third parties acting with lawful
authority. Other parties may seek to access the information
independently of Ford Motor Company and Ford of Canada.
Vehicle Modification Data Recording
Some aftermarket products may cause severe engine and/or transmission
damage; refer to theWhat is not coveredsection inThe new vehicle
limited warranty for your vehiclechapter of your vehicle’sWarranty
Guidefor more information. Some vehicles are equipped with
Powertrain Control Systems that can detect and store information about
vehicle modifications that increase horsepower and torque output; this
information cannot be erased and will stay in the system’s memory even
if the modification is removed. When a dealer or repair facility works on
your vehicle, it may be necessary for them to access the information in
the Powertrain Control System. This information will likely identify if any
unauthorized modifications have been made to the system and may be
used to determine if repairs will be covered by warranty.

Introduction

Note:If your vehicle is equipped with a manual transmission, the engine
may be required to run while power accessories operate and the parking
brake is set. It is recommended that wheel chocks be used during this
operation.
If you’re parking your vehicle on a grade or with a trailer, press and hold
the brake pedal down, then set the parking brake. There may be a little
vehicle movement as the parking brake sets to hold the vehicle’s weight.
This is normal and should be no reason for concern. If needed, press and
hold the service brake pedal down, then try reapplying the parking
brake. Chock the wheels if required. If the parking brake cannot hold the
weight of the vehicle, the parking brake may need to be serviced or the
vehicle may be overloaded.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the FULL COLD mark on the dipstick).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may

Shifting from 2WD (2WD High) to 4x4 HIGH (4WD High)
Rotate the 4WD control to the 4x4
HIGH position at speeds up to
55 mph (88 km/h).
•The electronic shift 4WD
system is designed to engage
4x4 HIGH (4WD High) when
the vehicle is moving. If
shifted to 4x4 HIGH (4WD
HIGH) while at complete stop,
4x4 may not engage and the
4x4 indicator may not
illuminate until the vehicle is allowed to move at a speed above
1 mph (1.6 km/h).
•Do not shift into 4x4 HIGH with the rear wheels slipping.
Shifting from 4x4 HIGH (4WD High) to 2WD (2WD High)
Rotate the 4WD control to 2WD at
any forward speed. Disengagement
of the transfer case and front hubs
may be delayed due to torque bind
which is caused by driving on dry
hard surfaces or performing tight
turns while using the 4WD system.
•Yo udo notneed to operate the vehicle in R (Reverse) to disengage
your front hubs, but it will eliminate any torque bind and allow the
system to immediately disengage.
Shifting from 4x4 HIGH (4WD High) to 4x4 LOW (4WD Low)
1. Bring the vehicle to a complete stop.
2. Depress the brake.
3. Place the gearshift in N (Neutral).

The following steps apply to all vehicles:
19. Remove the jack and fully
tighten the lug nuts in the order
shown. Refer toWheel lug nut
torque specificationslater in this
chapter for the proper lug nut
torque specification.
8–lug nut torque sequence
10–lug nut torque sequence
20. Stow the flat tire. Refer toStowing the spare tireif the vehicle is
equipped with a spare tire carrier.
Note:If your vehicle is equipped with 20” tires, do not stow the flat tire
and wheel using the spare tire winch mechanism; store the flat in the
bed of the truck.
21. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
22. Unblock the wheels.

Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing in the direction
specified on the Tire Changing Instructions located with the jack
hardware.
2. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
3. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your authorized
dealer for assistance at your earliest convenience.
4. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
5. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, perscheduled maintenance information),
or at any time that the spare tire is disturbed through service of other
components.
6. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key (if equipped) and jack handle.
WHEEL LUG NUT TORQUE SPECIFICATIONS
On vehicles equipped with single rear wheels, retighten the lug nuts to
the specified torque at 500 miles (800 km) after any wheel disturbance
(tire rotation, changing a flat tire, wheel removal, etc.).
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 100 miles (160 km), and again at 500 miles
(800 km) of new vehicle operation and after any wheel disturbance (tire
rotation, changing a flat tire, wheel removal, etc.).

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
On all two-piece flat wheel nuts,
apply one drop of motor oil between
the flat washer and the nut. Do not
apply motor oil to the wheel nut
threads or the wheel stud threads.
When a wheel is installed, always remove any corrosion, dirt or
foreign materials present on the mounting surfaces of the wheel
or the surface of the front disc brake hub and rotor that contacts the
wheel. Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen and the
wheel to come off while the vehicle is in motion, resulting in loss of
control.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
