Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-09-2020, enUSA, Edition date: 202010, Second-Printing Table of Contents

Thanks to a popular mix of appearance,
features and power, the 1969-73 Mach 1's
proved to be everyman's muscle car, and
have earned a respected place in Mustang
performance lore. Beyond those classic
years, the Mach 1 carried over for all five
years of the often overlooked 1974-78's
before a hiatus that ended with the
modern and muscular 2003-04's. Mach
1’
s return to the Mustang lineup for 2021
will add a new chapter on modern-day
muscle for this beloved model, and will
cement its rightful place near the very top
of Mustang performance history.

WHAT IS THE CABIN AIR
FILTER
The cabin air filter improves the quality of
air in your vehicle by trapping dust, pollen
and other particles.
LOCATING THE CABIN AIR
FILTER
The cabin air filter is behind the glovebox.
Note:
The filter access door is above the
passenger footwell under the instrument
panel.
REPLACING THE CABIN AIR
FILTER
Replace the filter at regular intervals. See
Scheduled Maintenance (page 441).
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system.
Note: Using an aftermarket cabin air filter
could reduce cabin air filtration and climate
control performance.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors can result in
reduced engine power and the illumination
of the service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design. The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
•
Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• Fuel system leaks, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, see your authorized
dealer as soon as possible.

•
Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly
terrain.
• Do not rest your foot on the brake
pedal while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C).
BREAKING-IN
Your vehicle requires a break-in period. For
the first 1,000 mi (1,600 km), avoid driving
at high speeds, heavy braking, aggressive
shifting or using your vehicle to tow. During
this time, your vehicle may exhibit some
unusual driving characteristics.
Ground Clearance
Since ground clearance is reduced, use
caution when approaching curbs or curb
stops from the front and rear as vehicle
damage may occur. Additionally, when
crossing speed bumps or driveway curbs,
you should approach at a 45 degree angle
to reduce the risk of vehicle damage. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
