tire size LINCOLN MKZ 2020 Owners Manual

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.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It’ s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’ s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions: •
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:

MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Stability Control

Note:
If you change any tires, the system
must recalibrate and may not correctly
operate for a short time.
Active park assist is a multi-step process and
may require you to shift the transmission
multiple times. Follow the onscreen
instructions until the parking maneuver is
complete.
If you are uncomfortable with the proximity
to any vehicle or object, you may choose to
override the system by grabbing the steering
wheel, or by taking full control of your vehicle
after pressing the active park assist button.
Keep your hands, hair, clothing and any
loose items clear of the steering wheel when
using active park assist.
The sensors are on the front and rear
bumpers.
The system may not correctly operate in any
of the following conditions:
• You use a spare tire or a tire that is
significantly worn more than the other
tires.
• One or more tires are incorrectly inflated.
• You try to park on a tight curve. •
Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow, fog,
high humidity and high temperatures.
Do not use the system if:
• You have attached an add-on accessory
close to the sensors on the front or rear
of your vehicle. For example, a bike rack
or trailer.
• You have attached an overhanging
object to the roof. For example, a
surfboard.
• The front bumper, rear bumper or the
side sensors are damaged.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire. Using Active Park Assist
Selecting an Active Park Assist Mode Press the button once to activate
parallel parking. Press the button
a second time to activate
perpendicular parking. If you press the
button again the system switches off.
If your vehicle is parked and after you switch
the ignition on, you can use the information
display to toggle through the modes. Press
the button to switch the system on and open
the system menu in the information display.
Note: If your vehicle is parked, the default
mode is parallel park out assist. However, if
you did not use active park assist to parallel
park your vehicle, use the information
display to select park out assist.
Note: You can repeatedly press the active
park assist button to toggle through the
modes only after moving your vehicle
approximately 33 ft (10 m).

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
Avoid driving too fast during the first 1,000 mi
(1,600 km)
. Vary your speed frequently and
change up through the gears early. Do not
labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
REDUCED ENGINE PERFORMANCE WARNING:
If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle. If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
102).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 308).
5. Have your vehicle checked as soon as possible. ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.

depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C
WARNING: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
The traction grades, from highest to
lowest are AA, A, B, and C. The grades
represent the tire ’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance. Temperature A B C WARNING:
The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire ’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
