On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine
’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. Your vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 156).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required. If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
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 reduces the
life of the clutch and could nullify a clutch
warranty claim.
Note: The engine may not start unless the
intelligent access key is inside your vehicle. Manual transmission vehicles have a
starter interlock that prevents cranking the
engine unless you fully press the clutch
pedal.
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
(N) 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, fully press the clutch
pedal to the floor. Make sure to properly
position the floor mat so it does not
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 damages the clutch.

Reverse (R)
Note:
Make sure that your vehicle is at a
complete stop before you shift into reverse
(R). Failure to do so could 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. Note:
The gearshift lever can only be
moved to reverse (R) by raising the collar
below the gearshift knob up before shifting
to reverse (R). 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 (N) 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 (N) position.
2. Fully apply the parking brake, hold the clutch pedal down, then shift into first
(1).
3. Turn the ignition off.
After you have turned the engine off, you
can release the clutch pedal.
AUTOMATIC TRANSMISSION
(IF EQUIPPED) WARNING:
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. WARNING:
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.

The instrument cluster displays the current
gear.
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 when 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
increases engine RPM during engine
braking.
• Provides additional lower gear
operation through the automatic
transmission shift strategy.
• Provides gear upshifts and downshifts
more quickly at higher engine speeds.
SelectShift Automatic ™
Transmission (If Equipped)
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, you
can downshift the vehicle. 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.
In drive (D) mode, SelectShift
automatically upshifts at the optimal max
engine speed, regardless of accelerator
pedal travel.

maneuvers where you require extra
control of gear selection, for example,
when towing or overtaking. This mode
holds a selected gear for a temporary
period of time dependent on driver
inputs, for example, steering or
accelerator pedal input.
SelectShift in sport (S):
• Provides a permanent manual gear
selection where you require full control
of gear selection.
To exit SelectShift mode shift the
transmission into another gear, for
example, drive (D), or hold the (+) paddle
for 2 seconds.
The instrument cluster displays your
currently selected gear. If a gear you
request is not available due to vehicle
conditions, the current gear flashes two
times. Brake-Shift Interlock WARNING: Do not drive your
vehicle until you verify that the
stoplamps are working. WARNING:
When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
Use the brake shift interlock lever to move
the gearshift lever from the park position
in the event of an electrical malfunction or
if your vehicle has a dead battery.
Apply the parking brake and switch the

authorized dealer as soon as possible.
Note: For some markets, this feature is
disabled. Automatic Transmission Adaptive
Learning
This feature is designed to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm or soft
shifts. This operation is normal and does
not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 296).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations. Note:
Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
could flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the anti-lock braking system may
be disabled. Have the system checked by
an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective.
See
Warning Lamps and Indicators
(page 94).
Note: Indicators vary depending on region. This lamp also illuminates
momentarily when you switch
the ignition on to confirm the
lamp is functional. If it does not
illuminate when you switch the
ignition on, or begins to flash at
any time, have the system checked by an
authorized dealer. If the brake warning
lamp illuminates with the parking brake
released, have the system checked
immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
171
Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Brakes E270480

•
You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
PARKING BRAKE
Vehicles With Automatic

brake and leave your vehicle with the
transmission in park (P).
Note: If you park your vehicle on a hill and
facing uphill, shift into park (P) and turn the
steering wheel away from the curb.
Note: If you park your vehicle on a hill and
facing downhill, shift into park (P) and turn
the steering wheel toward the curb.
Vehicles with Manual
Transmission 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.
Note: If you park your vehicle on a hill and
facing uphill, select first gear and turn the
steering wheel away from the curb.
Note: If you park your vehicle on a hill and
facing downhill, select reverse gear and turn
the steering wheel toward the curb.
To park your vehicle:

HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you
excessively rev the engine.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system activates, your vehicle
remains stationary on a slope for a few
seconds after you release the brake pedal.
This allows you time to move your foot
from the brake to the accelerator pedal.
The brakes release when the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note: There is no warning lamp to indicate
the system is either on or off. Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed and shift into
first gear when facing uphill or reverse
(R) when facing downhill.
2. The system activates if the sensors detect that your vehicle is on a slope.
3. When you remove your foot from the brake pedal, your vehicle remains on
the slope without rolling away for a few
seconds. This hold time increases if you
are in the process of driving off.
4. Pull away in the normal manner.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.
Vehicles with Automatic Transmission
The system turns on when you switch the
ignition on and you cannot switch the
system off.
