maintenance schedule FORD MUSTANG 2003 4.G User Guide

If the vehicle’s powertrain system or its battery has
just been serviced, the on-board diagnostics system
is reset to a“not ready for I/M test”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:
•First, at least 10 minutes of driving on an
expressway or highway.
•Next, 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.
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
MERCONAT F.
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.
If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. 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 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.
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.
MAXMIN
Maintenance and Specifications
226

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.
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

SERVICING YOUR TIRES
Checking the tire pressure
•Use an accurate tire pressure gauge.
•Check the tire pressure when tires are cold, after
the vehicle has been parked for at least one hour
or has been driven less than 5 km (3 miles).
•Adjust tire pressure to recommended
specifications found on the certification label on
the driver side door latch pillar.
Improperly inflated tires can affect vehicle
handling and can fail suddenly, possibly
resulting in loss of vehicle control.
Tire rotation
Because your vehicle’s tires perform different jobs,
they often wear differently. To make sure your tires
wear evenly and last longer, rotate them as indicated
in the scheduled maintenance guide. If you notice
that the tires wear unevenly, have them checked.
•15 or 16 inch four

the indication on the dipstick’s normal operating
range.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
