Traction ControlYactive
This light momentarily
illuminates when the
ignition is turned to
ON. It also illuminates
when the Traction Controlysystem begins applying
and releasing the brakes and adjusting the engine
characteristics to limit a wheelspin condition. It will
be lit for a minimum of four seconds or for the
duration of the Traction Controlyevent.
For more information, refer to theDrivingchapter.
Anti-lock brake system (ABS)
Momentarily illuminates
when the ignition is
turned to the ON
position and the engine
is off. If the light remains on, continues to flash or
fails to illuminate, have the system serviced
immediately. With the ABS light on, the anti-lock
brake system is disabled and normal braking is still
effective unless the brake warning light also remains
illuminated with parking brake released.
Brake system warning
Momentarily illuminates
when the ignition is
turned to the ON
position and the engine
is off. If brake warning lamp does not illuminate at
this time, seek service immediately. Also illuminates
when the parking brake is engaged. Illumination
after releasing the parking brake indicates low brake
fluid level and the brake system should be inspected
immediately.

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.
The BRAKE warning
lamp in the instrument
cluster illuminates and

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.

Power distribution box
The power distribution box is located in the engine
compartment. The power distribution box contains
high-current fuses that protect your vehicle's main
electrical systems from overloads.
Always disconnect the battery before
servicing high current fuses.
Always replace the cover to the Power
Distribution Box before reconnecting the
battery or refilling fluid reservoirs.
If the battery has been disconnected and
reconnected, refer to theBatterysection of the
Maintenance and Carechapter.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine
compartment for easy location.
²We provide a Scheduled Maintenance Guide which
makes tracking routine service easy.
If your vehicle requires professional service, your
dealership can provide necessary parts and service.
Check your ªWarranty Guideº to find out which parts
and services are covered.
Use only recommended fuels, lubricants, fluids and
service parts conforming to specifications. Motorcraft
parts are designed and built to provide the best
performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR
VEHICLE
Be especially careful when inspecting or servicing
your vehicle.
²Do not work on a hot engine.
²When the engine is running, keep loose clothing,
jewelry or long hair away from moving parts.
²Do not work on a vehicle with the engine running
in an enclosed space, unless you are sure you
have enough ventilation.
²Keep all lit cigarettes, open flames and other lit
material away from the battery and all fuel related
parts.
If you disconnect the battery, the engine must
ªrelearnº its idle conditions before your vehicle will
drive properly, as explained in theBatterysection in
this chapter.
Working with the engine off
²Automatic transmission:
1. Set the parking brake and ensure the gearshift is
securely latched in P (Park).

Engine oil and filter recommendations
Look for this
Certification
Trademark.
Use SAE 5W-30 motor oil certified for gasoline
engines by the American Petroleum Institute (API).
Motor oil displaying the API Certification Trademark
will meet all requirements for your vehicle's engine.
Ford oil specification is WSS-M2C153-G.
Do not use supplemental engine oil additives, oil
treatments or engine treatments. They are
unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your
warranty.
Change your engine oil and filter according to the
appropriate schedule listed in the Scheduled
Maintenance Guide.
Ford production and aftermarket (Motorcraft) oil
filters are designed for added engine protection and
long life. If a replacement oil filter is used that does
not meet Ford material and design specifications,
startup engine noises or knock may be experienced.
It is recommended you use the appropriate
Motorcraft oil filter (or another brand meeting Ford
specifications) for your engine application.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and refilled as
needed. Refer to the Scheduled Maintenance Guide
for the service interval schedules:
Maintenance and care

1. Clean the reservoir cap before removal to prevent
dirt or water from entering the reservoir.
2. Visually inspect the
fluid level.
3. If necessary, add
brake fluid until the
level reaches MAX. Do
not fill above this line.
4. Use only a DOT 3 brake fluid certified to meet
Ford specifications. Refer toLubricant
specificationsin theCapacities and specifications
chapter.

Brake fluid is toxic.
If you use a brake fluid that is not DOT 3,
you will cause permanent damage to your
brakes.
Do not let the reservoir for the master
cylinder run dry. This may cause the brakes
to fail.
CLUTCH ADJUSTMENT (IF EQUIPPED)
Check the clutch
adjustment. Refer to
the Scheduled
Maintenance Guide for
the service interval
schedules.
The clutch on your
vehicle is operated by a
cable. As necessary, adjust the clutch as described
below.
1. Turn the engine off and shift into 1 (First).
2. Put your foot under the clutch pedal and gently
pull it up until the pedal stops.
3. Push the clutch pedal down slowly. You will hear a
click as the clutch adjusts itself.
