FORD MUSTANG 2002 4.G Owners Manual

Conditions
²Heavily loading a vehicle or towing a trailer may
reduce fuel economy at any speed.
²Carrying unnecessary weight may reduce fuel
economy (approximately 0.4 km/L [1 mpg] is lost
for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for
example bug deflectors, rollbars/light bars,
running boards, ski/luggage racks) may reduce
fuel economy.
²Using fuel blended with alcohol may lower fuel
economy.
²Fuel economy may decrease with lower
temperatures during the first 12±16 km
(8±10 miles) of driving.
²Driving on flat terrain offers improved fuel
economy as compared to driving on hilly terrain.
²Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window
sticker. Contact your dealer if the window sticker is
not supplied with your vehicle. The EPA window
sticker should be your guide for the fuel economy
comparisons with other vehicles.
It is important to note the box in the lower left
corner of the window sticker. These numbers
represent the Range of L/100 km (MPG) expected
on the vehicle under optimum conditions. Your fuel
economy may vary depending upon the method of
operation and conditions.

EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission
control components and a catalytic converter which
will enable your vehicle to comply with applicable
exhaust emission standards. To make sure that the
catalytic converter and other emission control
components continue to work properly:
²Use only the specified fuel listed.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is
moving, especially at high speeds.
²Have the items listed in your scheduled
maintenance guide performed according to the
specified schedule.
The scheduled maintenance items listed in the
scheduled maintenance guide are essential to the life
and performance of your vehicle and to its emissions
system.
If other than Ford, Motorcraft or Ford-authorized parts
are used for maintenance replacements or for 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 ªService Engine Soonº 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.
Maintenance and Specifications
232

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 ªCheck Engine/Service Engine Soonº 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 ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a ªnot ready for I/M testº condition. To
ready the on-board diagnostics system for I/M
testing, a minimum of 30 minutes of city and
highway driving is necessary as described below:
²First, at least 10 minutes of driving on an
expressway or highway.
²Next, at least 20 minutes driving in stop-and-go,
city-type traffic with at least four idle periods.
Allow the vehicle to sit for at least eight hours
without starting the engine. Then, start the engine
and complete the above driving cycle. The engine
must warm up to its normal operating temperature.
Once started, do not turn off the engine until the
above driving cycle is complete.

TRANSMISSION FLUID
Checking automatic transmission fluid
(if equipped)
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.
Automatic transmission fluid expands when warmed.
To obtain an accurate fluid check, drive the vehicle
until it is at normal operating temperature
(approximately 30 km [20 miles]). If your vehicle has
been operated for an extended period at high
speeds, in city traffic during hot weather or pulling a
trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and engage the
parking brake.
3. With the parking brake engaged and your foot on
the brake pedal, start the engine and move the
gearshift lever through all of the gear ranges. Allow
sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean,
dry lint free rag. If necessary, refer toIdentifying
components in the engine compartmentin this
chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in
the filler tube.
7. Remove the dipstick and inspect the fluid level.
The fluid should be in the designated area for
normal operating temperature or ambient
temperature.
Maintenance and Specifications
238

Low fluid level
Do not drive the
vehicle if the fluid level
is at the bottom of the
dipstick and the ambient temperature is above 10ÉC
(50ÉF).
Correct fluid level
The transmission fluid should be checked at normal
operating temperature 66ÉC-77ÉC (150ÉF-170ÉF) on
a level surface. The normal operating temperature
can be reached after approximately 30 km
(20 miles) of driving.
You can check the fluid without driving if the
ambient temperature is above 10ÉC (50ÉF). However,
if fluid is added at this time, an overfill condition
could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66ÉC-77ÉC [150ÉF-170ÉF]).
The transmission fluid
should be in this range
if at ambient
temperature (10ÉC-35ÉC [50ÉF-95ÉF]).
High fluid level
Fluid levels above the
safe range may result
in transmission failure.
An overfill condition of transmission fluid may cause
shift and/or engagement concerns and/or possible
damage.
High fluid levels can be caused by an overheating
condition.
Maintenance and Specifications
239

Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type
is used. The type of fluid used is normally indicated
on the dipstick and also in theLubricant
specificationssection in this chapter.
Use of a non-approved automatic transmission
fluid may cause internal transmission
component damage.
If necessary, add fluid in 250 ml (1/2 pint)
increments through the filler tube until the level is
correct.
If an overfill occurs,
excess fluid should be
removed by a qualified
technician.
An overfill condition of transmission fluid may
cause shift and/or engagement concerns and/or
possible damage.
Checking and adding manual transmission fluid
(if equipped)
1. Clean the filler plug.
2. Remove the filler
plug and inspect the
fluid level.
