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 267).
• 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.

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.

Note:
If you attempt to leave your vehicle
while it is in gear, the vehicle will
automatically shift into park (P). Safety belt
and door monitors determine your intent and
make the shift for you. During this time, a
message will appear in the information
display screen prompting you to make the
shift. See Information Messages (page 115).
Note: To put your vehicle in gear with the
door open, perform steps 1-4. See the
Automatic Return to Park
section in this
chapter for more information on this feature.
Park (P)
With the transmission in park (P), your vehicle
locks the transmission and prevents the front
wheels from turning. Always come to a
complete stop before putting your vehicle
into and out of park (P). An audible chime
sounds once you select park (P).
When the ignition is turned off, the vehicle
will automatically shift into park (P). If the
ignition is turned off while the vehicle is
moving, it will first shift into neutral (N) until
a slow enough speed is reached. The vehicle
will then shift into park (P) automatically. Automatic Return to Park
Note:
This feature will not operate when your
vehicle is in Stay in Neutral mode or neutral
tow.
Your vehicle has a safety feature that will
automatically shift your vehicle into park (P)
when any of the following conditions occur:
• You turn the ignition off
• You open the driver's door with your
safety belt unlatched
• Your safety belt is unlatched while the
driver's door is open
If you turn the ignition off while your vehicle
is moving, your vehicle will first shift into
neutral (N) until it slows down enough to shift
into park (P) automatically.
Note: If you have waited an extended period
of time, (2-15 minutes) before starting your
vehicle, unlatching your safety belt will cause
this feature to activate, even with the driver's
door closed. Note:
This feature may not work properly if
the door ajar switch is malfunctioning. If your
door ajar indicator does not illuminate when
you open the driver’ s door or the indicator
illuminates with the driver’ s door closed. See
your authorized dealer.
Reverse (R)
With the transmission in reverse (R), your
vehicle will move backward. Always come
to a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the transmission in neutral (N), you can
start your vehicle and it is free to roll. Hold
the brake pedal down while in this position.

All-Wheel Drive Messages
Action / Description
AWD Messages
Displays when the system automatically disables to protect itself. This
may be caused by operating the vehicle with the compact tire installed,
if the system is overheating or if there is an issue with another vehicl\
e
system preventing AWD operation. The system resumes normal
operation and clears this message after cycling the ignition on and
off and driving a short distance with the road tire re-installed, after
the system is allowed to cool or after the other vehicle system issues
are resolved.
AWD OFF
Displays in conjunction with the powertrain malfunction or reduced
power light when the system is not operating properly. If the message
stays on or continues to come on, contact your authorized dealer as
soon as possible.
AWD Malfunction Service Required
185
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing All-Wheel Drive (If Equipped)

Operating AWD Vehicles With Spare
or 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. A spare tire of a different size other than the
tire provided should never be used. The
AWD system may disable automatically and
enter front-wheel drive only mode to protect
driveline components if a non-full sized tire
is installed. This condition may display an
AWD OFF
message in the information
display. If there is an AWD OFF message in
the information display from using a non-full
sized spare tire, this indicator should turn off
after reinstalling the repaired or replaced
normal road tire and cycling the ignition off
and on. It is recommended to reinstall the
repaired or replaced road tire as soon as
possible.
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 front-wheel drive or damage the AWD
system. However, the AWD system is
capable of tolerating any combination of new
and worn tires of the same original tire size.
For example, using 3 worn tread tires and 1
new tread tire all of the same original tire
size, can be tolerated by the AWD system. Driving In Special Conditions With All-
Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
186
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing All-Wheel Drive
(If Equipped)

If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle back
onto the pavement only after reducing
your speed. Do not turn the steering
wheel too sharply while returning to the
road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors, with
minor damage to your vehicle rather than
attempt a sudden return to the pavement
which could cause the vehicle to slide
sideways out of control or rollover.
Remember, your safety and the safety of
others should be your primary concern. If Your Vehicle Gets Stuck WARNING: Always set the parking
brake fully and make sure you shift the
gearshift lever to park (P). Switch the
ignition off and remove the key whenever
you leave your vehicle. 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. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires may occur or the engine may
overheat. If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability Control™, it
may be beneficial to disengage the
AdvanceTrac® with Roll Stability Control™
system while attempting to rock the vehicle.
Emergency Maneuvers
•
In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle (that is, turn the steering
wheel only as rapidly and as far as
required to avoid the emergency).
Excessive steering will result in less
vehicle control, not more. Additionally,
smooth variations of the accelerator
and/or brake pedal pressure should be
utilized if changes in vehicle speed are
called for. Avoid abrupt steering,
187
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing All-Wheel Drive
(If Equipped)

acceleration or braking which could result
in an increased risk of loss of vehicle
control, vehicle rollover and/or personal
injury. Use all available road surface to
return the vehicle to a safe direction of
travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (that is, from concrete
to gravel) there will be a change in the
way the vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
Most of the time traction control improves
tire traction by managing wheel slip through
Brake, Engine, and AWD calibrations.
However, during low speed driving, disabling
traction control in deep sand can help keep
the wheels moving to maintain vehicle
momentum. When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels.
Do not drive your vehicle in deep sand for
an extended period of time. This could cause
the AWD system to overheat and default to
front-wheel drive. If this occurs, an AWD OFF
message displays in the information display.
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 has been restarted and the
AWD system has adequately cooled, the
AWD OFF message turns off and normal
AWD function returns. In the event the
engine is not stopped, the
AWD OFF
message turns off when the system cools
and normal AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L (Low)
gear when possible. L (Low) gear operation
will maximize the engine and transmission
cooling capability. Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Avoid excessive speed because vehicle
momentum can work against you and cause
the vehicle to become stuck to the point that
assistance may be required from another
vehicle. Remember, you may be able to back
out the way you came if you proceed with
caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom of
the hubs (for trucks) (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.
