1999 Mercury Grand Marquis power steering

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 located on the left side of the
glove compartment.
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.
The traction control must be turned off if you are using a mini-spare tire
in a rear tire position.
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 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.
If you use the temporary spare tire continuously or do not follow
these precautions, the tire could fail, causing you to lose control
of the vehicle, possibly injuring yourself or others.

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
symbol will begin to flash.
²if your vehicle is equipped with digital gauges, the gauge bars will
flash and a tone will sound every five seconds for one minute.
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 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 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.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your Scheduled Maintenance Guide for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
