1997 FORD F150 lock

Each time the vehicle is started,
the transmission will automatically
return to normal overdrive mode.
2 (Second)± Use 2 (Second) to
start-up on slippery roads or to
provide additional engine braking
on downgrades. Transmission
operates in first and second gears.
1 (Low)± Use 1 (Low) to provide
maximum engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
D(Overdrive). Selecting 1 (Low)
at higher speeds causes a shift to 2
(Second), and will shift to 1 (Low)
after vehicle decelerates to the
proper speed.
Brake-shift interlock
The brake-shift interlock feature
prevents you from shifting from P
(Park) unless the brake pedal is
depressed (with the ignition in the
On position). If you cannot move
the gearshift out of P (Park) with
the brake pedal depressed:
1. Turn ignition key to Off.

4. Re-insert the ignition key and
turn it to Off.
5. Shift the transmission to N
(Neutral).
6. Start the vehicle.
If you need to use the above
procedure, it is possible that a fuse
has blown and your brakelamps
may not be functioning. Refer to
theRoadside emergencies
chapter for instructions on
replacing fuses.
Do not drive your vehicle
until you verify that the
brakelamps are working.
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 ignition to 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 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 accidently
shifting into R (Reverse) when you
downshift from
D(Overdrive).

FOUR-WHEEL DRIVE
OPERATION (4WD) (IF
EQUIPPED)
When Four±wheel drive (4WD) is
engaged, power is supplied to all
four wheels through a transfer
case. 4WD power can be selected
when additional driving power is
desired.
All utility-type vehicles and 4WD
vehicles have special design and
equipment features to make them
capable of performing in a wide
variety of off-road applications.
Specific design characteristics give
them higher centers of gravity than
ordinary passenger cars.

When descending a steep hill,
avoid sudden braking. Rapid
pumping of the brake pedal will
help slow the vehicle and still
maintain steering control.
When speed control is on and you
are driving uphill, your vehicle
speed may drop considerably,
especially if you are carrying a
heavy load.
If vehicle speed drops more than
15±25 km/h (8±14 mph), the speed
control will cancel automatically.
Resume speed with accelerator
pedal.
If speed control cancels after
climbing the hill, reset speed by
pressing and holding the SET
ACCEL button (to resume speeds
over 50 km/h (30 mph).
Automatic transmission may shift
frequently while driving up steep
grades. Eliminate frequent shifting
by shifting out of
D(Overdrive)
into D (Drive).
Driving on snow and ice
A 4WD vehicle has advantages
over 2WD vehicles in snow and ice
but can skid like any other vehicle.
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.
When braking, apply the brakes as
you normally would. In order to
allow the anti-lock brake system
(ABS) to operate properly, keep

Instrument panel fuses
Always replace a fuse with
one that has the specified
amperage rating. Using a fuse
with a higher amperage rating
can cause severe wire damage
and could start a fire.
