lock FORD F150 2002 10.G Repair Manual

Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling people and cargo may raise the center of gravity of the vehicle.
Use extra caution while becoming familiar with your vehicle. Know the
capabilities and limitations of both you as a driver and your vehicle.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF.Apply the brake pedal and shift
to N (Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting from forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.

Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Driving with a 4±speed automatic transmission
Understanding gearshift positions
To put your vehicle in gear, start the engine, depress the brake pedal,
then move gearshift lever out of P (Park).
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift lever is securely
latched in P (Park). This position
locks the transmission and prevents
the rear wheels from turning.
Always set the parking brake fully and make sure the gearshift
lever is latched in P (Park). Turn off the ignition whenever you
leave your vehicle.
R (Reverse)
With the gearshift lever in R
(Reverse), the vehicle will move
backward. Always come to a
complete stop before shifting into
and out of R (Reverse).

2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low) at
higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
Forced Downshifts
To gain acceleration in(Overdrive) or Drive (O/D OFF) when
passing another vehicle, push the accelerator to the floor. The
transmission will downshift to the appropriate gear: third, second or first
gear.
Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronically controls the shift quality by using
an adaptive learning strategy. The adaptive learning strategy is
maintained by power from the battery. When the battery is disconnected
or a new battery is installed, the transmission must relearn its adaptive
strategy. Optimal shifting will resume within a few hundred kilometers
(miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual transmission have a starter interlock
that prevents cranking the engine unless the clutch pedal is fully
depressed.

4. Turn the ignition key to position
3 (OFF).
Do not park your vehicle in Neutral, it may move unexpectedly
and injure someone. Use 1 (First) gear and set the parking brake
fully.
Reverse
Make sure that your vehicle is at a complete stop before you shift into R
(Reverse). Failure to do so may damage the transmission.
Put the gearshift in N (Neutral) and
wait at least three seconds before
shifting into R (Reverse).
You can shift into R (Reverse) only
by moving the gearshift lever from
left of 3 (Third) and 4 (Fourth)
gears before you shift into R
(Reverse). This is a special lockout
feature that protects you from
accidentally shifting into R
(Reverse) when you downshift
from
D(Overdrive).

4WD Systems (if equipped)
4WD (when you select the 4WD mode), uses all four wheels to power
itself. This increases traction, enabling you to drive over terrain and road
conditions that a conventional two-wheel drive vehicle can't.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 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.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Driving
191

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral, disengage
overdrive or manually shift to a
lower gear. When descending a
steep hill, avoid sudden hard
braking as you could lose control.
When you brake hard, the front
wheels can't turn and if they aren't
turning, you won't be able to steer.
The front wheels have to be turning in order to steer the vehicle. Rapid
pumping of the brake pedal will help you slow the vehicle and still
maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
ªpumpº the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won't stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles for
stopping as well as drive slower than usual and consider using one of the
lower gears. In emergency stopping situations, avoid locking of the wheels.
Use a ªsqueezeº technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you may
steer in the direction you want to travel. If you lock the wheels, release the
brake pedal and repeat the squeeze technique. If your vehicle is equipped
with a Four Wheel Anti-Lock Brake System (ABS), apply the brake steadily.
Do not ªpumpº the brakes. Refer to theBrakessection of this chapter for
additional information on the operation of the anti-lock brake system.
Driving
194

Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
4WD vehicles are equipped with tires designed to provide for safe ride
and handling capability.
Do not use a size and type of tire and wheel other than that originally
provided by Ford because it can affect the safety and performance of
your vehicle, which could lead to loss of vehicle control or roll over and
serious injury. Make sure all tires and wheels on the vehicle are of the
same size, type, tread design, brand and load-carrying capacity. If you
have questions regarding tire replacement, see an authorized Ford or
Lincoln/Mercury dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford recommends, you should not use these tires for
highway driving.
If you use any tire/wheel combination not recommended by Ford, it may
adversely affect vehicle handling and could cause steering, suspension,
axle or transfer case failure.
Do not useºaftermarket lift kitsº or other suspension modifications,
whether or not they are used with larger tires and wheels.
These ªaftermarket lift kitsº could adversely affect the vehicle's handling
characteristics, which could lead to loss of vehicle control or roll over
and serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford recommended pressure even if it is less
than the maximum pressure allowed for the tire.

Installing the snowplow
Removing the blocker beam without installing snowplow
attachment hardware may affect air bag deployment in a crash.
Do not operate the truck unless either the blocker beam or snowplow
attachment hardware is installed on the vehicle.
Read the following instructions before installing a snowplow:
²Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find Front GAWR.
²The Front Axle Accessory Reserve Capacity and the Total Accessory
Reserve Capacity listed on the bottom right of the Safety Compliance
Certification Label will determine whether or not the addition of a
snowplow will overload your vehicle.
²The weight of the snowplow and supporting components distributed to
the front axle must not exceed the front accessory reserve capacity.
²The total weight of the snowplow and aftermarket equipment must
not exceed the Total Accessory Reserve Capacity.
²The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
²The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the Gross
Combined Weight Rating (GCWR) for towing.
²Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
²After installing a snowplow to the vehicle, ensure the vehicle's front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle's Workshop
Manual. Adherence to the toe, tire pressures and ride height
specification is important for proper tire wear, ride, handling and
headlight aim. Also, maintain the engine oil and transmission fluid
change intervals following the severe duty schedule.
Do not exceed the GVWR or the GAWR specified on the
certification label.
