Ford Mustang (2018 year). Manual — part 35

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.

If the vehicle’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.

The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.

If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:

1.

15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.

2. Allow your vehicle to sit for at least

eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.

If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

MANUAL TRANSMISSION

Using the Clutch

Note: Failure to fully press the clutch pedal
to the floor may cause increased shift
efforts, prematurely wear transmission
components or damage the transmission.

Note: Do not drive with your foot resting
on the clutch pedal or use the clutch pedal
to hold your vehicle at a standstill while
waiting on a hill. These actions will reduce
the life of the clutch and could nullify a
clutch warranty claim.

E144954

Manual transmission vehicles have a
starter interlock that prevents cranking the
engine unless the clutch pedal is fully
pressed.

To start the vehicle:

1.

Make sure the parking brake is fully set.

2. Press the clutch pedal to the floor, then

put the gearshift lever in the neutral
position.

3. Start the engine.

4. Press the brake pedal and move the

gearshift lever to the desired gear; first
(1) or reverse (R).

5. Release the parking brake, then slowly

release the clutch pedal while slowly
pressing on the accelerator.

During each shift, the clutch pedal must
be fully pressed to the floor. Make sure the
floor mat is properly positioned so it
doesn't interfere with the full extension of
the clutch pedal.

Recommended Shift Speeds

Note: Do not downshift into first (1) when
your vehicle is moving faster than 15 mph
(24 km/h). This will damage the clutch.

Reverse

Note: Make sure that your vehicle is at a
complete stop before you shift into reverse
(R). Failure to do so may damage the
transmission.

1.

Press the clutch pedal to the floor to
disengage clutch.

2. Shift into reverse (R) by raising the

collar below the gearshift knob up, then
moving the lever fully to the left, then
forward.

E99067

Note: The gearshift lever can only be
moved to reverse (R) by raising the collar
below the gearshift knob up before shifting
to reverse. This is a lockout feature which
protects the transmission from accidentally
engaging reverse (R) when intending to
select first (1).

If reverse (R) is not fully engaged, press
the clutch pedal down and return the
gearshift to the neutral position. Release
the clutch pedal for a moment, then raise
the collar and shift to reverse (R) again.

Parking Your Vehicle

WARNING

Always set the parking brake fully
and make sure you shift the gearshift
lever to first gear. Switch the ignition

off and remove the key whenever you leave
your vehicle.

To park your vehicle:

1.

Apply the brake and shift into the
neutral position.

2. Fully apply the parking brake, hold the

clutch pedal down, then shift into first
(1).

3. Turn the ignition off.

AUTOMATIC TRANSMISSION

(If Equipped)

WARNINGS

Always fully apply the parking brake
and make sure you shift into park (P).
Failure to follow this instruction

could result in personal injury or death.

Do not apply the brake pedal and
accelerator pedal simultaneously.
Applying both pedals simultaneously

for more than a few seconds will limit
engine performance, which may result in
difficulty maintaining speed in traffic and
could lead to serious injury.

Note: You may not be able to shift out of
park (P) unless the intelligent access key is
inside your vehicle.

Understanding the Positions of
Your Automatic Transmission

Putting your vehicle in gear:

1.

Fully press down on the brake pedal.

2. Press and hold the button on the top

of the gearshift lever.

3. Move the gearshift lever into the

desired gear.

4. Release the button and your

transmission remains in the selected
gear.

E174572

Park (P)

This position locks the transmission and
prevents the rear wheels from turning.
Come to a complete stop before putting
your vehicle into and out of park (P).

Reverse (R)

With the selector in reverse (R), your
vehicle moves backward. Always come to
a complete stop before shifting into and
out of reverse (R).

Neutral (N)

With the selector in neutral (N), you can
start your vehicle and it is free to roll. Hold
the brake pedal down while in this position.

Drive (D)

Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through all gears.

Sport (S)

Putting your vehicle in sport (S):
•

Provides additional engine braking and
extends lower gear operation to
enhance performance for uphill climbs,
hilly terrain or mountainous areas. This
will increase engine RPM during engine
braking.

•

Provides additional lower gear
operation through the automatic
transmission shift strategy.

•

Provides gear selection more quickly
and at higher engine speeds.

SelectShift Automatic™
Transmission

This feature gives you the ability to change
gears up or down as desired.

As long as the engine speed does not
exceed the maximum allowable limit,
downshifts are allowed. SelectShift
automatically downshifts at low engine
speeds in order to prevent engine stalls.

Note: Engine damage may occur if you
maintain excessive engine revving without
shifting.

SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit, unless the accelerator pedal is at full
travel.

Pull the + paddle on the steering wheel
to activate SelectShift.

•

Pull the right paddle (+) to upshift.

•

Pull the left paddle (–) to downshift.
