1998 FORD F150 lock

shudder while braking, felt mainly
in the steering wheel, the vehicle
most likely needs service.
The ABS operates by detecting the
onset of wheel lock up during
brake applications and
compensating for this tendency.
The front wheels are prevented
from locking even when the brakes
are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking.
ABS warning lamp
The
ABSwarning lamp in the
instrument cluster illuminates for
about five seconds when starting
the vehicle. If an ABS fault is
detected, the light will remain on
and your vehicle should be
serviced as soon as possible.
Normal braking is still effective
unless the BRAKE warning lamp is
also illuminated.
Using ABS
²In an emergency or when
maximum efficiency from the
ABS is required, apply
continuous full force on the
brake. The ABS will be activated
immediately, thus allowing you
to retain full steering control of
your vehicle and, providing

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.
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.
When starting a vehicle with a
manual transmission, you must:

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 accidentally
shifting into R (Reverse) when you
downshift from
D(Overdrive).

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
steady pressure on the brake
pedal.
Allow more stopping distance and
drive slower than usual. Consider
using one of the lower gears.
