ECU FORD MUSTANG 2001 4.G User Guide

Always set the parking brake fully and make
sure that the gearshift is securely latched in
P (Park) (automatic transmission) or in 1 (First
Gear) (manual transmission).
The parking brake is not recommended to stop a
moving vehicle. However, if the normal brakes fail,
the parking brake can be used to stop your vehicle
in an emergency. Since the parking brake applies
only the rear brakes, the vehicle's stopping distance
will increase greatly and the handling of your vehicle
will be adversely affected.
To release the parking
brake, the brake
handle may need to be
pulled up slightly to
release pressure before
pushing in the button.
Push the button on the
end of the parking
brake handle and push the handle down as far as
possible. Driving with the parking brake applied will
cause the brakes to wear out quickly and reduce fuel
economy.
TRACTION CONTROLY
Your vehicle may be equipped with the optional
Traction Controlysystem. This system helps you
maintain the stability and steerability of your
vehicle. It is especially useful on slippery road
surfaces. The system operates by detecting and
controlling wheel spin. The system borrows many of
the electronic and mechanical elements already
present in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to
be detected by the Traction Controlyportion of the
ABS computer. Any excessive wheel spin is
controlled by automatically applying and releasing
the rear brakes in conjunction with engine torque

Understanding gearshift positions
P (Park)
Always come to a
complete stop before
shifting into P (Park).
Make sure the gearshift
lever is securely
latched in P (Park).
This position locks the

prevents the rear
wheels from turning.
Always set the parking brake fully and make
sure the gearshift lever is latched in P
(Park). Turn off the ignition whenever you leave
your vehicle.
R (Reverse)
With the gearshift lever
in R (Reverse), the
vehicle will move
backward. Always come
to a complete stop
before shifting into and
out of R (Reverse).
N (Neutral)
With the gearshift lever
in N (Neutral), the
vehicle can be started
and is free to roll. Hold
the brake pedal down
while in this gear.

Failure to follow these precautions may
adversely affect the handling of the vehicle
and make it easier for the driver to lose control
and roll over.
Tires that are larger or smaller than your vehicle's
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving
at very high speeds for extended periods of time
may result in damage to vehicle components.
Snow tires must be the same size and grade
as the tires you currently have on your
vehicle.
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and chains.
Use chains on the tires only in an emergency or if the
law requires them.
Follow these guidelines when using snow tires and
chains:
²Chains may damage aluminum wheels.
²Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage your vehicle.
²SAE Class S chains may be used on P205/65R15
tires.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.

To install the new bulb:
Handle a halogen headlamp bulb carefully
and keep out of children's reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.
1. With the flat side of the new bulb's plastic base
facing upward, insert the glass end of the bulb into
the lamp assembly. You may need to turn the bulb
left or right to align the grooves in the plastic base
with the tabs in the lamp assembly. When the
grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of
the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a ªstop.º
3. Connect the electrical connector into the plastic
base until it snaps, locking it into position.
4. Install the headlamp on vehicle by aligning the
lamp with the rear snap retainers, push to seat and
secure with two retainer pins.
5. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.
Replacing front parking lamp/turn signal bulbs
1. Make sure the headlamp control is in the OFF
position.
2. Open the hood.
