power steering FORD EXPEDITION 1999 1.G Owners Manual

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to help steer the vehicle.
To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
²Do not operate the vehicle with a low power steering pump fluid level.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
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

Speed sensitive steering
The steering in your vehicle is speed sensitive. At high speeds, steering
assist will decrease to improve steering feel. At lower speeds,
maneuverability will be increased.
If the amount of effort required to steer your vehicle changes at a
constant vehicle speed, have the power steering system checked by your
dealer or a qualified service technician.
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.
²The height adjustment feature automatically controls the vehicle
height over a range of approximately 5 cm (2 inches) based on vehicle
speed, ignition position and selection of two or four-wheel drive
modes.
²The air suspension automatically puts the vehicle at its lowest height
when ignition if OFF to provide easy entry and exit. When ever a door
is opened (including the liftgate) the system memorizes and maintains
the height of the vehicle until all doors are closed or until vehicle
exceeds 16km/h (10mph).
²The air suspension system raises the vehicle to its normal ride
position when the ignition is turned on, all doors are closed and the
transmission is shifted into gear.
²In 4WD Low the air suspension system will not move to it's lowest
height. In 4WD Low, the air suspension system raises the vehicle
above the normal ride height at speeds below 40 km/h (25 mph) to
improve ground clearance. In 4WD Low, do not exceed 56 km/h
(35 mph).
²When the vehicle is in motion, the air suspension system will adjust
the vehicle's height according to ground clearance and speed to
maximize ride comfort.
²It is normal to occasionally hear a buzz or clicking from the vehicle's
air suspension system when the ignition is turned off. The system
stays energized for 40 minutes after the ignition is turned off to
compensate for any load changes made after the vehicle is parked.

level in which you drive during winter months. Never increase the engine
coolant concentration above 60%. Leave a 50/50 mixture of engine
coolant and water in your vehicle year-round in non-extreme climates.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The ªfail-safeº distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
²the engine coolant temperature
gauge will move to the red (hot)
area.
²the
symbol will illuminate.
²the
symbol will illuminate.
²theService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate, however:
²the engine power will be limited.
²the air conditioning system will be disabled.
Continued operation will increase the engine temperature:
²the engine will completely shut down.
²steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. Remember that the engine is

capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re start the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid. Refer to the Scheduled Maintenance
Guide for the service interval schedules. If adding fluid is necessary, use
only Ford Premium Power Steering Fluid.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.

1Refer to the dipstick for the type of transmission fluid required. Some
fluid labels may indicate dual usage such as MERCONtand MERCON
Vt. These dual usage fluids are not to be used in transmissions that use
only the MERCONttype fluid. These dual usage fluids may be used in
transmissions that require MERCONtV use.
Using a transmission fluid that indicates a dual usage (MERCONtand
MERCON Vt) in a transmission application requiring MERCONtmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
2Add 118 ml (4 oz.) of EST-M2C118±A (friction modifier Part No.
