Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER 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:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. 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. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 353).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Engine Emission Control

The scheduled maintenance items listed in
scheduled maintenance information are
essential to the life and performance of your
vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service of
components affecting emission control, such
non-Ford parts should be equivalent to
genuine Ford Motor Company parts in
performance and durability.
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 229).
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.

USING ALL-WHEEL DRIVE
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
The intelligent AWD system continuously
monitors vehicle conditions and adjusts the
power distribution between the front and
rear wheels. It combines transparent
all-surface operation with highly capable
all-wheel drive.
The AWD system is always active and
requires no driver input. It is capable of
handling all road conditions including street
and highway driving as well as off-road and
winter driving. You can optimize more AWD
control by selecting different drive modes.
See
Selecting a Drive Mode (page 329). Note:
A warning message displays in the
information display when an AWD system
fault is present. See Information Messages
(page 140). A AWD system fault causes the
AWD system to default to rear-wheel drive
only mode. When this warning message is
displayed, have your vehicle serviced at an
authorized dealer.
Note: A warning message displays in the
information display if the AWD system
overheats.
See Information Messages
(page 140). This condition could occur if the
vehicle is operated in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After the engine is restarted and
the AWD system is adequately cooled, the
warning message turns off and normal AWD
function returns. Operating All-Wheel Drive (AWD)
Vehicles With Spare Tires
Do not use a different size spare tire other
than the tire provided. If the mini-spare tire
is installed, the AWD system will disable and
enter rear-wheel drive only mode to protect
driveline components. Some limited AWD
traction could be provided if the mini-spare
is installed on one of the front wheels. If you
are in driving conditions where limited AWD
traction is needed while the mini-spare is
installed, it is recommended the mini-spare
be installed on the front axle.
If the mini-spare is installed, this condition is
indicated by a warning in the information
display.
The slip response system could activate if
the mini spare is installed on the front
wheels. If the mini spare was installed on the
rear wheels the slip response system will
fully disable. In situations where there is a
wintery mix or an off road situation, and you
need to use a mini spare, you must install
the mini spare in the front tire position and
move a full size tire to the rear tire position
for the slip response system to function.

Operating ALL-Wheel drive (AWD)
Vehicles with Mismatched Tires
WARNING: Only use replacement
tires and wheels that are the same size,
load index, speed rating and type (such as
P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), or the Tire Label
which is located on the B-Pillar or edge of
the driver's door. If this information is not
found on these labels, then you should
contact your authorized dealer as soon as
possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death. Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch high
profile tires on the rear axle) could cause the
AWD system to stop functioning and default
to rear-wheel drive or damage the AWD
system.
For optimum AWD Performance, it is
recommended to follow the tire rotation
maintenance schedule. To avoid potential
AWD malfunction or AWD system damage,
it is recommended to replace all four tires
rather than mixing significantly worn tires
with new tires. For example, using 3 worn
tread tires and 1 new tread tire all of the same
original tire size/brand, can be tolerated by
the AWD system as long as the worn tires
still have usable tread depth.
How Your Vehicle Differs from Other
Vehicles
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components. The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.
Maintain steering wheel control at all times,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the area.
To maintain steering and braking control of
your vehicle, you must have all four wheels
on the ground and they must be rolling, not
sliding or spinning.
