1999 FORD F150 warning

If the steering wanders or pulls, the condition could be caused by any of
the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance for static, on and off-road driving conditions.
²The load leveling feature of the air suspension automatically keeps the
vehicle at a constant level if a load is added or removed from the
vehicle.
The air suspension shut-off switch is
located behind an access panel
underneath the passenger side
instrument panel.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.
Check air suspension light
The warning and indicator light CK SUSP illuminates when the air
suspension switch is turned off or an air suspension system fault has
been detected.
If the light is displayed while driving and the air suspension system
switch is not turned off, safely pull off the road at your earliest
convenience. Turn the ignition switch from 4 (On) to 3 (Off) and 4 (On)

again. If the warning light reappears, turn the air suspension switch off
and have the vehicle serviced by a dealer or qualified service technician.
If the vehicle is loaded beyond the recommended maximum payload, the
CK SUSP light may illuminate. To correct this condition, remove or
redistribute the payload according to the recommended requirements
and follow the procedure outlined above.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
depressed.
If you cannot move the gearshift out of P (Park) with 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, 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 for more than a few minutes. The
transmission and tires may be damaged 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
Pull the gearshift lever towards you and downward to move the
automatic gearshift.
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 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 is
securely latched in P (Park).
Never leave your vehicle unattended while it is running.
R (Reverse)
With the gearshift in R (Reverse),
the vehicle will move backward.
Always come to a complete stop
before shifting into and out of R
(Reverse).
Driving
121

Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Illumination of the charging system warning light,Check Engine
indicator light or the temperature warning light, fluid leaks, strange
odors, smoke or loss of oil pressure, could indicate that the emission
control system is not working properly.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By law,
vehicle owners and anyone who manufactures, repairs, services, sells, leases,
trades vehicles, or supervises a fleet of vehicles are not permitted to
intentionally remove an emission control device or prevent it from working.
Information about your vehicle's emission system is on the Vehicle Emission
Control Information Decal located on or near the engine. This decal
identifies engine displacement and gives some tune up specifications.
Please consult your ªWarranty Guideº for complete emission warranty
information.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of the
on-board diagnostic (OBD-II) system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning Lights and
Chimessection of theInstrumentationchapter. Your vehicle may not pass
the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ªnot ready for I/M testº condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
