2003 FORD MUSTANG instrument cluster

ABSwarning lampABS
TheABSwarning lamp in the instrument cluster
momentarily illuminates when the ignition is turned
to the ON position. If the light does not illuminate
momentarily at start up, remains on or continues to
flash, the ABS needs to be serviced.
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. (If your
brake warning lamp illuminates, have your vehicle
serviced immediately.)
Using ABS
•In an emergency or when maximum efficiency
from the four-wheel ABS is required, apply
continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing
you to retain full steering control of your vehicle
and, providing there is sufficient space, will
enable you to avoid obstacles and bring the
vehicle to a controlled stop.
•The anti-lock system does not reduce stopping
distance. Always leave enough room between your
vehicle and the vehicle in front of you to stop.
•We 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

(Overdrive)
The normal driving
position for the best
fuel economy.
Transmission operates
in gears one through
four.
(Overdrive) can be
deactivated by pressing
the transmission
control switch on the
gearshift lever.
The transmission
control indicator light
(TCIL) will illuminate
on the instrument
cluster.
Drive–Not shown on the display. Activate by
pressing the transmission control switch on the
gearshift lever with the gearshift in the
position.
The O/D OFF indicator will illuminate on the
instrument cluster. Transmission operates in gears
one through three.
(Drive) provides more engine
braking than
(Overdrive) and is useful when:
•driving with a heavy load.
•towing a trailer up or down steep hills.
•additional engine braking is desired. If towing a
trailer, refer toDriving while you towin this
chapter.

PLASTIC (NON-PAINTED) EXTERIOR PARTS
Use only approved products to clean plastic parts.
These products are available from your dealer.
•For routine cleaning, use Detail Wash (ZC-3–A).
•If tar or grease spots are present, use Ford Extra
Strength Tar and Road Oil Removal
(B7A-19520–AA).
WINDOWS AND WIPER BLADES
The windshield, rear window and wiper blades
should be cleaned regularly. If the wiper does not
wipe properly, substances on the windshield, rear
window or the wiper blades may be the cause. These
may include hot wax treatments used by commercial
car washes, tree sap, or other organic contamination.
To clean these items, please follow these tips:
•The windshield or rear window may be cleaned
with a non-abrasive cleaner such as Motorcraft
Ultra Clear Spray Glass Cleaner (ZC-23), available
from your dealer.
•Do not use abrasives, as they may cause
scratches.
•Do not use fuel, kerosene, or paint thinner to
clean any parts.
•Wiper blades can be cleaned with isopropyl
(rubbing) alcohol or windshield washer solution.
Be sure to replace wiper blades when they appear
worn or do not function properly.
INSTRUMENT PANEL AND CLUSTER LENS
Clean the instrument panel with a damp cloth, then
dry with a dry cloth.
•Avoid cleaners or polish that increase the gloss of
the upper portion of the instrument panel. The
dull finish in this area helps protect the driver
from undesirable windshield reflection.
Cleaning

•You may need to cycle the ignition from OFF to
ON several times after refueling, to allow the fuel
system to pump the fuel from the tank to the
engine.
•Your“Service Engine Soon”indicator may come
on. For more information on the“Service Engine
Soon”indicator, refer to theInstrument cluster
chapter.
Fuel Filter
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the scheduled
maintenance guide for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized
Motorcraft part. The customer warranty may
be void for any damage to the fuel system if an
authorized Motorcraft fuel filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel
economy is you, the driver. You must gather
information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel
gauge readings are NOT accurate as a measure of
fuel economy. We do not recommend taking fuel
economy measurements during the first 1,600 km
(1,000 miles) of driving (engine break-in period).
You will get a more accurate measurement after
3,000 km–5,000 km (2,000 miles-3,000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your
vehicle is equal to the rated refill capacity of the fuel
tank as listed in theRefill capacitiessection of this
chapter.
The advertised capacity is the amount of the
indicated capacity and the empty reserve combined.
Indicated capacity is the difference in the amount of

service of components affecting emission control,
such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and
durability.
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine compartment
and exhaust system, which can start a fire.
Illumination of the“Service Engine Soon”light,
charging system warning light or the temperature
warning light, fluid leaks, strange odors, smoke or
loss of engine power, could indicate that the
emission control system is not working properly.
Exhaust leaks may result in entry of harmful
and potentially lethal fumes into the
passenger compartment.
Do not make any unauthorized changes to your
vehicle or engine. By law, vehicle owners and anyone
who manufactures, repairs, services, sells, leases,
trades vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an emission
control device or prevent it from working.
Information about your vehicle’s emission system is
on the Vehicle Emission Control Information Decal
located on or near the engine. This decal identifies
engine displacement and gives some tune up
specifications.
Please consult yourWarranty Guidefor complete
emission warranty information.
Readiness for Inspection/Maintenance (I/M)
testing
In some localities, it may be a legal requirement to
pass an I/M test of the on-board diagnostics system.
If your“Check Engine/Service Engine Soon”light is
on, refer to the description in theWarning lights
and chimessection of theInstrument cluster
chapter. Your vehicle may not pass the I/M test with
the“Check Engine/Service Engine Soon”light on.
