1999 FORD MUSTANG power steering

stopping distance. Always leave enough room
between your vehicle and the vehicle in front of
you to stop.
²We recommend that you familiarize yourself with
this braking technique. However, avoid taking any
unnecessary risks.
Hydraulic brake booster system (Hydroboost)
The Hydroboost system receives fluid pressure from
the power steering pump to provide power assist
during braking.
The sound of the pump operating may be heard by
the driver, but this is a normal characteristic of the
system.
For Hydroboost-equipped vehicles operating under
normal conditions, the noise of the fluid flowing
through the booster may be heard whenever the
brake is applied. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response becomes
very poor, even when the pedal is strongly
depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle
safely as soon as possible and seek service
immediately.
Parking brake
Apply the parking
brake whenever the
vehicle is parked. To
set the parking brake,
apply the brake pedal
and pull the parking
brake handle up as far
as possible.

cluster illuminates and

controlled by automatically applying and releasing
the rear brakes in conjunction with engine torque
reductions. Engine torque reduction is realized via
the fully electronic spark and fuel injection systems.
This process is very sensitive to driving conditions
and very fast acting. The rear wheels ªsearchº for
optimum traction several times a second and
adjustments are made accordingly.
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, ice covered and gravel roads.
During Traction
Controlyoperation,
the traction control
active light will
illuminate, 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.
The Traction Controlyon/off switch, located in front
of the gearshift, illuminates when the system is OFF.
The Traction Controlysystem will revert to the ON
position every time the ignition is turned OFF and
ON.
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 a system fault is detected the warning indicator
lamp is and your vehicle should be serviced.
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
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.

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.

Always dispose of used automotive fluids in a
responsible manner. Follow your community's
regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle's cooling
system can hold, refer toRefill capacitiesin the
Capacities and specificationschapter.
Have your dealer check the engine cooling system
for leaks if you have to add more than 1.0 liter (1.0
quart) of engine coolant per month.
Severe winter climate
If you drive in extremely cold climates (less than
±36ÉC [±34ÉF]), it may be necessary to increase the
coolant concentration above 50%. Refer to the chart
on the coolant container to ensure the coolant
concentration in your vehicle is such that the
coolant will not freeze at the temperature level in
which you drive during winter months. Never
increase the coolant concentration above 60%.
Increased engine coolant concentrations above 60%
will decrease the freeze protection characteristics of
the engine coolant. Vehicles driven year-round in
non-extreme climates should use a 50/50 mixture of
engine coolant and distilled water for optimum
freeze protection.
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.
Maintenance and care

If your vehicle is
equipped with the
3.8L V6 engine,check
the power steering
fluid level with the
engine at normal
operating temperature.
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 on the dipstick. It should be
within the FULL HOT range. Do not add fluid if the
level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.
