FASTENING THE SEATBELTS
The front outboard and rear safety
restraints in the vehicle are combination
lap and shoulder belts.
E142587
1. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
until you hear a snap and feel it latch.
Make sure you securely fasten the
tongue in the buckle.
E142588
2. To unfasten, press the release button
and remove the tongue from the
buckle.
Using the Seatbelt with Cinch
Tongue (Front Center and Rear
Center Seats Only)
The cinch tongue slides up and down the
belt webbing when the belt is stowed or
while putting seatbelts on. When the lap
and shoulder seatbelt is buckled, the cinch
tongue allows the lap portion to be
shortened, but pinches the webbing to
keep the lap portion from getting longer.
The cinch tongue is designed to slip during
a crash, so always wear the shoulder belt
properly and do not allow any slack in
either the lap or shoulder portions.
Before you can reach and latch a lap and
shoulder belt having a cinch tongue into
the buckle, you may have to lengthen the
lap belt portion of it.
E1162708E162708
1. To lengthen the lap belt, pull some
webbing out of the shoulder belt
retractor.
2. While holding the webbing below the
tongue, grasp the tip (metal portion)
of the tongue so that it is parallel to the
webbing and slide the tongue upward.
3. Provide enough lap belt length so that
the tongue can reach the buckle.

Seatbelts

Fastening the Cinch Tongue
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips.
1. Pull the lap and shoulder belt from the
retractor so that the shoulder belt
portion of the seatbelt crosses your
shoulder and chest.
2. Be sure the belt is not twisted. If the
belt is twisted, remove the twist.
3. Insert the belt tongue into the proper
buckle for your seating position until
you hear a snap and feel it latch.
4. Make sure the tongue is securely
fastened to the buckle by pulling on
the tongue.
While you are fastened in the seatbelt, the
lap and shoulder belt with a cinch tongue
adjusts to your movement. However, if you
brake hard, turn hard, or if your vehicle
receives an impact of 5 mph (8 km/h) or
more, the seatbelt will become locked and
help reduce your forward movement.
Lap Belts
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips.
The front center lap belt does not adjust
automatically.
E208768
Insert the tongue into the correct buckle
(the buckle closest to the direction the
tongue is coming from). To lengthen the
belt, turn the tongue at a right angle to the
belt and pull across your lap until it reaches
the buckle. To tighten the belt, pull the
loose end of the belt through the tongue
until it fits snugly across the hips.
E208769
Shorten and fasten the belt when not in
use.

Putting your vehicle in or out of gear:
1. Fully press the brake pedal.2. Move the gearshift lever into the
preferred gear.
3. When you finish driving, come to a
complete stop.
4. Move the gearshift lever and securely
latch it in park (P) or neutral (N).
The instrument cluster displays the current
gear.
Park (P)
If your transmission has a park (P) position,
this position locks the transmission and
prevents the rear wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), your
vehicle moves backward. Always come to
a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), you
can start your vehicle and it is free to roll.
Hold the brake pedal down when in this
position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through gears one through six.
Manual (M)
With the gearshift lever in manual (M), the
driver can change gears up or down as
preferred. By moving the gearshift lever
from drive (D) to manual (M), you now
have control of selecting the gear you
prefer using the buttons on the shift lever.

Transmission

Your vehicle has a brake-shift interlock
feature that prevents the gearshift lever
from moving from park (P) when you
switch the ignition on but have not pressed
the brake pedal.
If you cannot move the gearshift lever out
of the park (P) position with the ignition in
the on position and the brake pedal
pressed, a malfunction could have
occurred. It is possible that a fuse has
blown, or your vehicle’s brake lamps are
not operating properly. See Fuse
Specification Chart (page 200).
If you do not have a blown fuse and the
brake lamps are working properly, the
following procedure allows you to move
the gearshift lever from park (P):
1. Apply the parking brake. Switch the
ignition key to off, then remove the key.
2. Move the steering column to the full
down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.
4. Place your fingers into the hole where
you removed the gearshift lever boot
and pull the top half of the shroud up
and forward to separate it from the
lower half of the shroud. There is a
hinge at the forward edge of the top of
the shroud. Roll the top half of the
shroud upward on the hinge point, then
pull straight rearward toward the driver
seat to remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under the
column that secure the lower shroud
half to the column.

7. Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover.
8. Apply the brake. Gently lift the override
disk and move the gearshift lever into
neutral (N).
E163186E163186
9. Start your vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as you rotate the halves together.

5. Tighten the nut until the spring is fully
caged and brakes released. Do not
loosen or remove the release stud and
nut unless you completely assemble
and securely clamp the brake chamber.
6. After restoring the air pressure,

HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake.
WARNING: You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death.
WARNING: The system will turn
off if a malfunction is apparent or if you
rev the engine excessively. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine hasdeveloped sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. If the sensors detect that your vehicle
is on a slope, the system activates
automatically.
3. When you remove your foot from the
brake pedal, your vehicle remains on
the slope without rolling away for
about two to three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The
system releases the brakes
automatically.
Note:When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.

Brakes

• Your load shifts due to improper
retention, accident damage or the
inherently mobile nature of some loads,
for example, hanging meat, live
animals or partially laden tankers.
• Your vehicle or load has an unusually
high or off-set center of gravity.
• Your brakes are not properly adjusted
or maintained.
• One side of your vehicle drops off the
pavement at an angle that is too great
to be counteracted by a reduction in
speed.
To Maximize the Effectiveness Of
Stability Control
• Make sure that the weight of your load
is evenly distributed, from front to back,
side to side and you secure it properly
at all times.
• Exercise extreme caution at all times
while driving and avoid sharp turns,
sudden steering inputs or abrupt lane
changes at high speeds, particularly if:
• Hauling loads that can shift.
• Your vehicle or load has a high or
off-set center of gravity when
loaded.
• You are towing doubles or triples.
Electronic Stability Control Usage with
Tractor/Trailer
The electronic stability control system is
designed to work with trailer air brake
systems. We do not recommend its use
with any other trailer brake system.
Electronic Stability Control and Towing
with Non-tractor Trucks (Straight or
Kick-up Frame)
Non-tractor trucks (straight or kick-up
frame) with air brake electronic stability
control, should not be used for towing any
type of trailer.Chassis Modifications
Stability control is specifically calibrated
and validated only for your vehicle's
original configuration. If you alter your
vehicle's chassis components, for example,
a wheel base extension or reduction, tag
axle addition or removal, a major body
change such as conversion of a tractor into
a truck. Ford Motor Company is not
responsible for the performance of the
stability control system if you modify any
major components such as axle,
suspension or steering system.
