How Your Vehicle Differs From Other
Vehicles
WARNING
Vehicles with a higher center of gravity
such as utility and four-wheel drive
vehicles handle differently than vehicles with
a lower center of gravity. Utility and
four-wheel drive vehicles are not designed
for cornering at speeds as high as passenger
cars any more than low-slung sports cars are
designed to perform satisfactorily under
off-road conditions. Avoid sharp turns,
excessive speed and abrupt maneuvers in
these vehicles. Failure to drive cautiously
could result in an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components.
The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car. Maintain steering wheel control at all times,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the area.
To maintain steering and braking control of
your vehicle, you must have all four wheels
on the ground and they must be rolling, not
sliding or spinning.
Driving Off-Road With Truck and Utility
Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern. Note:
Your vehicle may be equipped with a
front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing two bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud and
rough terrain and have operating
characteristics that are somewhat different
from conventional vehicles, both on and off
the road.
Power is supplied to all four wheels through
a transfer case. On Four-wheel drive
vehicles, the transfer case allows you to
select different 4WD modes when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.

Note:
The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on this vehicle.
If you get a flat tire while driving, do not apply
the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road.
Have a flat serviced by an authorized dealer
in order to prevent damage to the system
sensors See Tire Pressure Monitoring
System (page 313). Replace the spare tire
with a road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the system
sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING
Failure to follow these guidelines could
result in an increased risk of loss of
vehicle control, injury or death. If you have a dissimilar spare wheel and tire,
then it is intended for temporary use only.
This means that if you need to use it, you
should replace it as soon as possible with a
road wheel and tire assembly that is the
same size and type as the road tires and
wheels that were originally provided by Ford.
If the dissimilar spare tire or wheel is
damaged, it should be replaced rather than
repaired.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire assembly
that is different in brand, size or appearance
from the road tires and wheels and can be
one of three types:
1. T-type mini-spare: This spare tire begins
with the letter T for tire size and may have
Temporary Use Only molded in the sidewall.
2.
Full-size dissimilar spare with label on
wheel: This spare tire has a label on the
wheel that states: THIS WHEEL AND TIRE
ASSEMBLY FOR TEMPORARY USE ONLY When driving with one of the dissimilar spare
tires listed above, do not:
•
Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
• Use commercial car washing equipment.
• Try to repair the dissimilar spare tire.
Use of one of the dissimilar spare tires listed
above at any one wheel location can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability.

3. Full-size dissimilar spare without label
on wheel
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
• Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use commercial car washing equipment.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly. The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
•
Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability. When driving with the full-size dissimilar
spare wheel and tire assembly additional
caution should be given to:
•
Towing a trailer.
• Driving vehicles equipped with a camper
body.
• Driving vehicles with a load on the cargo
rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly and
seek service as soon as possible.
Location of the Spare Tire and Tools
The spare tire is located under the vehicle,
just forward of the rear bumper. The jack,
jack handle and lug wrench are located in
the following locations: Location
Item
Under the vehicle, just forward of the rear bumper
Spare tire
Under the access panel located in the floor compartment behind therear seat
Jack tools

Rear jacking point 1. With the vehicle on level ground, block
both sides of the wheel diagonally
opposite (other side and end of the
vehicle) to the wheel being changed. Do
not jack the vehicle on a hill or incline.
2. Obtain the spare tire and jack tools from
their storage locations.
3. Use the tip of the jack handle to remove
any wheel trim.
4. Loosen each wheel lug nut one-half turn
counterclockwise but do not remove
them until the wheel is raised off the
ground.
5. Position the jack according to the jack locator arrows found on the frame and
turn the jack handle and extension tool
assembly clockwise.
6. Raise the vehicle to provide sufficient ground clearance when installing the
spare tire, about 1/4 inch (6 millimeters).
7. Remove the lug nuts with the lug wrench. Installing the Spare Tire
1. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward.
2. Reinstall the lug nuts until the wheel is snug against the hub. Do not fully tighten
the lug nuts until the wheel has been
lowered.
3. Lower the wheel by turning the jack handle counterclockwise. 4.
Remove the jack and fully tighten the lug
nuts in the order shown. See Technical
Specifications (page 326).
