WARNING: Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The Safety Canopy deploys during
significant side crashes or when a certain
likelihood of a rollover event is detected
by the rollover sensor. The Safety Canopy
is mounted to the roof side rail sheet metal,
behind the headliner, above each row of
seats. In certain sideways crashes or
rollover events, the Safety Canopy will be
activated, regardless of which seats are
occupied. The Safety Canopy is designed
to inflate between the side window area
and occupants to further enhance
protection provided in side impact crashes
and rollover events. The system consists of the following:
•
Safety Canopy curtain airbags above
the trim panels over the front and rear
side windows identified by a label or
wording on the headliner or roof-pillar
trim.
• A flexible headliner which opens above
the side doors to allow air curtain
deployment · Crash sensors and monitoring
system with a readiness
indicator. See
Crash Sensors
and Airbag Indicator (page 46).
Properly restrain children 12 years old and
under in the rear seats. The Safety Canopy
will not interfere with children restrained
using a properly installed child or booster
seat because it is designed to inflate
downward from the headliner above the
doors along the side window opening.
The design and development of the Safety
Canopy included recommended testing
procedures that were developed by a
group of automotive safety experts known
as the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of injuries
related to the deployment of side airbags
(including the Safety Canopy).

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.
Your vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module. The restraints control module
deploys (activates) the front seatbelt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags and Safety Canopy airbags. Based
on the type of crash, the restraints control
module will deploy the appropriate safety
devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following: The readiness light will not
illuminate immediately after you
switch the ignition on. •
The readiness light either flashes or
stays lit.
• You will hear a series of five beeps. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The seatbelt pretensioners and the front
airbag supplemental restraint system are
designed to activate when the vehicle
sustains frontal deceleration sufficient to
cause the restraints control module to
deploy a safety device.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal, side crashes and rollovers.

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
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 139).
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.
145
Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-05-2018, enUSA, Edition date: 201804, Second-Printing Engine Emission Control

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.

Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-05-2018, enUSA, Edition date: 201804, Second-Printing Engine Emission Control

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active. Switching the System Off The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See
Principle of
Operation (page 48).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates
either of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on:
• When you switch the traction control
system off.
• When you select an alternative stability
control mode.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's
load in the Load Carrying chapter. See
Load Limit
(page 191).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
Safety Chains
Note: Never attach safety chains to the
bumper.
Always connect the safety chains to the
hook retainers of your vehicle hitch.
To connect the safety chains, cross them
under the trailer tongue and allow enough
slack for turning tight corners. Do not allow
the chains to drag on the ground. Trailer Brakes WARNING:
Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Trailer Lamps WARNING:
Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, direction indicators and hazard lights
are working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure
to follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about
2 –4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure. CHANGING A ROAD WHEEL
(IF
EQUIPPED) WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 284). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring system sensor for
damage.
