battery FORD MUSTANG 2021 Owner's Manual

GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage. WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING: Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic.
Always open the garage door before you
start the engine. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately
5 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You
can disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine. KEYLESS STARTING
Note:
The keyless starting system may not
function if the key is close to metal objects
or electronic devices such as cellular
phones.
Note: A valid key must be located inside
your vehicle to switch the ignition on and
start the engine.
Ignition Modes The keyless starting system has three
modes:
Off:
Turns the ignition off.
• Without applying the brake pedal,
press and release the button once
when the ignition is in the on mode, or
when the engine is running but the
vehicle is not moving.

•
Press the brake pedal (automatic
transmission) or clutch pedal (manual
transmission), and then press the
button for any length of time. An
indicator light on the button illuminates
when the ignition is on and when the
engine starts.
STEERING WHEEL LOCK
Your vehicle has an electronically
controlled steering wheel lock that
automatically operates.
The steering wheel will lock shortly after
you have parked your vehicle and the
passive key is outside it or when you lock
your vehicle.
Note: The steering wheel will not lock when
the ignition is on or when your vehicle is
moving.
Unlocking the Steering Wheel
The steering wheel unlocks when the
system detects a valid passive key inside
your vehicle. If the steering wheel relocks,
switch the ignition on to unlock it.
Note: You may have to slightly rotate the
steering wheel to assist unlocking it.
STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer. Note:
You can crank the engine for a total
of 60 seconds (without the engine starting)
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each
time, without the engine starting, you
reached the 60-second time limit. A
message appears in the information display
alerting you that you exceeded the cranking
time. You cannot attempt to start the engine
for at least 15 minutes. After 15 minutes, you
are limited to a 15-second engine cranking
time. You need to wait 60 minutes before
you can crank the engine for 60 seconds
again.
Before starting the engine, check the
following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Move the transmission selector lever
to park (P) (automatic transmission)
or neutral (manual transmission)
Note: Do not touch the accelerator pedal.
Note: You must have your intelligent access
key in the vehicle in order to shift the
transmission out of position P.
1. Fully press the brake pedal.
2. Press the button.
The system does not function if:
• The key frequencies are jammed.
• The key battery has no charge.
If you are unable to start the engine, do the
following:

3. With the key in this position, press the brake pedal (automatic transmission)
or clutch pedal (manual transmission),
then the START button to switch the
ignition on and start your vehicle.
Fast Restart
The fast restart feature allows you to
restart the engine within 20 seconds of
switching it off, even if a valid key is not
present.
Within 20 seconds of switching the engine
off, press the brake pedal (automatic
transmission) or clutch pedal (manual
transmission) and press the button. After
20 seconds have expired, you can no
longer restart the engine without the key
present inside your vehicle.
Once the engine has started, it remains
running until you press the button, even if
the system does not detect a valid key. If
you open and close a door while the engine
is running, the system searches for a valid
key. You cannot restart the engine if the
system does not detect a valid key within
20 seconds. Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. If your vehicle is equipped with an
automatic transmission, fully press the
brake pedal. If your vehicle is equipped
with a manual transmission, fully press
the clutch pedal and apply the
handbrake.
2. Move the transmission selector lever to park (P) (automatic transmission)
or neutral (manual transmission).
3. Fully press the accelerator pedal and hold it there.
4. Start the engine.
Automatic Engine Shutdown
Your vehicle is equipped with a feature that
automatically shuts down the engine if it
has been idling for an extended period. The
ignition also turns off in order to save
battery power. Before the engine shuts
down, a message appears in the
information display showing a timer
counting down from 30 seconds. If you do
not intervene within 30 seconds, the engine
shuts down. Another message appears in
the information display to inform you that
the engine has shut down in order to save
fuel. Start your vehicle as you normally do.
Automatic Engine Shutdown Override
Note: You cannot permanently switch off
the automatic engine shutdown feature.
When you switch it off temporarily, it turns
on at the next ignition cycle.
You can stop the engine shutdown, or reset
the timer, at any point before the
30-second countdown has expired by
doing any of the following:

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 camera is located on the rear cargo
door.
Using the Rear View Camera
System
The rear view camera system displays
what is behind your vehicle when you place
the transmission in reverse (R).
Note:
The reverse sensing system is not
effective at speeds above 3 mph (5 km/h)
and may not detect certain angular or
moving objects.
The system uses two types of guides to
help you see what is behind your vehicle:
• Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object.
Note: If the transmission is in reverse (R)
and the luggage compartment is open, no
camera features will display. The camera may not operate correctly
under the following conditions:
•
Nighttime or dark areas if the reverse
lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner.
• The camera is misaligned due to
damage to the rear of your vehicle.
Camera Guidelines
Note: Active guidelines are only available
when the transmission is in reverse (R).
Note: Upon a battery disconnect, the active
guidelines may not be functional until your
vehicle has been driven a short distance and
exceeds a speed of
12 mph (20 km/h).

If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning (If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems. PRE-COLLISION ASSIST
(IF
EQUIPPED) 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 does not
