1998 FORD CROWN VICTORIA power steering

The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Controlyoperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
ªrev-upº when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Controlysystem off. This may allow
excess wheel spin to ªdigº the vehicle out and enable a successful
ªrockingº maneuver.
If the Traction Controlysystem is cycled excessively, the brake portion
of the system will shut down to prevent the rear brakes from
overheating. A limited Traction Controlyfunction using only engine
torque reduction will still control wheels from over-spinning. When the
rear brakes have cooled down, the system will again function normally.
Anti-lock braking is not affected by this condition and will function
normally during the cool down period.
If the engine coolant temperature is below þ23ÉC (þ10ÉF) the engine
torque reduction portion of the Traction Controlysystem isNOTactive.
The system will operate normally when the engine coolant warms up.
The traction control indicator
flashes during a Traction Controly
system event.
If the traction control indicator
comes on and stays lit, either:
²the Traction Controlysystem
requires service, or
²the customer has disabled the
system using the traction control switch.
The Traction Controlysystem will be on every time you turn the ignition
key from OFF to ON until you deactivate the system using the traction
control switch in the glove compartment.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to help steer the vehicle.

Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running. This action
could damage the power steering pump.
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 during:
²certain road conditions
²steering maneuvers
²braking
²accelerations
This system keeps the rear of your vehicle at a constant level by
automatically adding air or releasing air from the springs.
The air suspension shut-off switch is
located on the left side of the trunk.
If this switch is in the OFF position,
the rear air suspension will not
operate.
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.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Temporary spare tire information
Your vehicle may have a temporary or full-size spare tire. The temporary
spare tire for your vehicle is labeled as such. It is smaller than a regular
tire and is designed for emergency use only. Replace this tire with a
full-size tire as soon as possible.

²thesymbol will begin to flash.
²if your vehicle is equipped with digital gauges, the gauge bars will
flash and a tone will sound continuously for thirty seconds.
²the engine will completely shut down, causing steering and braking
effort to 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 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 ªService Guideº for the
service interval schedules. If adding
fluid is necessary, use only
MERCONtAT F.
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.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.

1If your engine coolant is green in color, use Ford Premium Cooling
System Fluid. If your coolant is orange in color, use Ford Extended Life
Engine Coolant. Refer toLubricant Specifications.
2Add 118 ml (4 oz.) of additive friction modifier C8AZ-19B546±A, Ford
specification EST-M2C118±A for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.
Rear axles are considered lubricated for life when the vehicle is used for
normal service. See your ªService Guideº for Severe Duty requirements.
