Lincoln MKX (2018 year). Manual - part 22

E145298

Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.

Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to reduce
the risk of an accident or serious injury.

All-wheel drive system (if equipped)

WARNING

Do not become overconfident in the
ability of four-wheel drive vehicles.

Although a four-wheel drive vehicle may
accelerate better than a two-wheel drive
vehicle in low traction situations, it won't stop
any faster than two-wheel drive vehicles.
Always drive at a safe speed.

A vehicle equipped with all-wheel drive has
the ability to use all four wheels to power
itself. This increases traction which may
enable you to safely drive over terrain and
road conditions that a conventional
two-wheel drive vehicle cannot.

For all-wheel-drive vehicles, a spare tire of
a different size other than the tire provided
should never be used. A dissimilar spare tire
size; other than the spare tire provided or
major dissimilar tire sized between the front
and rear axles could cause the
all-wheel-drive system to stop functioning
and default to front-wheel drive.

How your vehicle differs from other
vehicles

Sport utility vehicles and trucks can differ
from some other vehicles in a few noticeable
ways. Your vehicle may be:

343

MKX (CD9) Canada/United States of America, enUSA, Edition date: 201707, Second Printing

Wheels and Tires

E145299

•

Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up or
damaging underbody components.

•

Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up or
damaging underbody components. All
other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.

•

Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.

MKX (CD9) Canada/United States of America, enUSA, Edition date: 201707, Second Printing

Wheels and Tires

As a result of the above dimensional
differences, Sport utility vehicles and trucks
often have a higher center of gravity and a
greater difference in center of gravity
between the loaded and unloaded condition.
These differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.

TIRE SEALANT AND INFLATOR KIT

(If Equipped)

Note: The temporary mobility kit contains
enough sealant compound in the canister
for one tire repair only. See an authorized
Ford dealer for replacement sealant
canisters.

The kit is located under the load floor in the
trunk. The kit consists of an air compressor
to re-inflate the tire and a canister of sealing
compound that will effectively seal most
punctures caused by nails or similar objects.
This kit provides a temporary tire repair,
allowing you to drive your vehicle up to
120 mi (200 km) at a maximum speed of
50 mph (80 km/h) to reach a tire service
location.

General Information

WARNING

Failure to follow these guidelines could
result in an increased risk of loss of

vehicle control, injury or death.

Note: Do not use the kit if you have severely
damaged a tire. Only seal punctures located
within the tire tread with the kit.

Do not attempt to repair punctures larger
than ¼ inch (6 millimeters) or damage to the
tire's sidewall. The tire may not completely
seal.

Loss of air pressure may adversely affect tire
performance. For this reason:

Note: Do not drive the vehicle above 50 mph
(80 km/h).

Note: Do not drive further than 120 mi
(200 km). Drive only to the closest authorized
Ford dealer or tire repair shop to have your
tire inspected.

•

Drive carefully and avoid abrupt steering
maneuvers.

•

Periodically monitor tire inflation pressure
in the affected tire; if the tire is losing
pressure, have the vehicle towed.

•

Read the information in the Tips for Use
of the Kit section to make sure safe
operation of the kit and your vehicle.

Tips for Use of the Kit

To ensure safe operation of the kit:

•

Read all instructions and cautions fully.

•

Before operating the kit, make sure your
vehicle is safely off the road and away
from moving traffic. Switch on the hazard
lights.

•

Always set the parking brake to ensure
the vehicle does not move unexpectedly.

•

Do not remove any foreign objects, such
as nails or screws, from the tire.

•

When using the kit, leave the engine
running (only if the vehicle is outdoors or
in a well-ventilated area) so the
compressor does not drain the vehicle's
battery.

•

Do not allow the compressor to operate
continuously for more than 15 minutes.
This will help prevent the compressor
from overheating.

•

Never leave the kit unattended during
operation.

•

Sealant compound contains latex. Those
with latex sensitivities should use
appropriate precautions to avoid an
allergic reaction.

•

Keep the kit away from children.

•

Only use the kit when the ambient
temperature is between -22°F (-30°C) and
158°F (70°C).

•

Only use the sealing compound before
the use-by date. The use-by date is on a
label on the sealant canister, which you
can see through the rectangular viewing
window on the bottom of the compressor.
Check the use-by date regularly and
replace the canister after four years of
non-use.

•

Do not store the kit unsecured inside the
passenger compartment of the vehicle
as it may cause injury during a sudden
stop or crash. Always store the kit in its
original location.

•

After sealant use, an authorized Ford
dealer must replace the tire pressure
monitoring system sensor and valve stem
on the wheel.

•

Operating the kit could cause an
electrical disturbance in radio, CD and
DVD player operation.

E175978

* When inflation only is required for
a tire or other objects, the selector
must be in the Air position.

What to do When a Tire Is Punctured

You can repair a tire puncture within the tire's
tread area in two stages with the kit.

•

In the first stage, inflate the tire with a
sealing compound and air. After you
inflate the tire, you will need to drive the
vehicle a short distance 4 mi (6 km) to
distribute the sealant in the tire.

•

In the second stage, check the tire
pressure and adjust, if necessary, to the
vehicle's specified tire inflation pressure.

First Stage: Inflating the Tire with
Sealing Compound and Air

WARNINGS

Do not stand directly over the kit while
inflating the tire. If you notice any

unusual bulges or deformations in the tire's
sidewall during inflation, stop and call
roadside assistance.

If the tire does not inflate to the
recommended tire pressure within 15

minutes, stop and call roadside assistance.

WARNINGS

Do not run the engine when operating
the air compressor unless the vehicle

is outdoors or in a well-ventilated area.

Preparation: Park the vehicle in a safe, level
and secure area, away from moving traffic.

Switch the hazard lights on. Apply the
parking brake and switch the engine off.
Inspect the flat tire for visible damage.

Sealant compound contains latex. Use
appropriate precautions to avoid any allergic
reactions.

Do not remove any foreign object that has
pierced the tire. If a puncture is located in
the tire sidewall, stop and call roadside
assistance.

1. Remove the valve cap from the tire valve.

2. Unwrap the dual purpose hose (black

tube) from the back of the compressor
housing.

3. Fasten the hose to the tire valve by

turning the connector clockwise. Tighten
the connection securely.

4. Plug the power cable into the 12-volt

power point in the vehicle.

5. Remove the warning sticker found on the

casing/housing and place it on the top of
the instrument panel or the center of the
dash.

6. Start the vehicle and leave the engine

running so the compressor does not
drain the vehicle’s battery.

E175981

7. Turn dial (A) clockwise to the sealant

position. Switch the kit on by pressing
the on/off button (B).

8. Inflate the tire to the pressure listed on

the tire label located on the driver's door
or the door jamb area. The initial air
pressure gauge reading may indicate a
value higher than the label pressure
while you pump the sealing compound
into the tire. This is normal and should
be no reason for concern. The pressure
gauge reading will indicate the tire
inflation pressure after about 30 seconds
of operation. You should check the final
tire pressure with the compressor turned
OFF in order to get an accurate pressure
reading.

9. When the tire reaches the recommended

tire pressure, switch off the kit, unplug
the power cable, and disconnect the
hose from the tire valve. Re-install the
valve cap on the tire valve and return the
kit to the stowage area.

10.

Immediately and cautiously, drive the
vehicle 4 mi (6 km) to distribute the
sealant evenly inside the tire. Do not
exceed 50 mph (80 km/h).

11.

After 4 mi (6 km), stop and check the
tire pressure. See Second Stage:
Checking Tire Pressure.

Note: If you experience any unusual
vibration, ride disturbance or noise while
driving, reduce your speed until you can
safely pull off to the side of the road to call
for roadside assistance. Note: Do not
proceed to the second stage of this
operation.

Second Stage: Checking Tire Pressure

Note: If you are proceeding from the First
Stage: Re-inflating the Tire with Sealing
Compound and Air section and have injected
sealant in the tire and the pressure is below
20 psi (1.4 bar), continue to the next step.

WARNING

The power plug may get hot after use
and should be handled carefully when

unplugging.

Check the air pressure of your tires as
follows:

1. Remove the valve cap from the tire valve.

2. Firmly screw the air compressor hose

onto the valve stem by turning clockwise.

3. Push and turn the dial clockwise to the

air position.

4. If required, switch on the compressor and

adjust the tire to the recommended
inflation pressure shown on the tire label
located on the driver's door or door jamb
area. You should check the tire pressure
with the compressor turned OFF in order
to get an accurate pressure reading.

5. Unplug the hoses, re-install the valve cap

on the tire and return the kit to the
stowage area.

What to Do After the Tire has Been
Sealed

After using the kit to seal your tire, you will
need to replace the sealant canister. You
can obtain sealant canisters and spare parts
at an authorized Ford dealer. You can
dispose of empty sealant canisters at home.
However, you should dispose of canisters
still containing liquid sealant through your
local authorized Ford dealer or tire dealer,
or in accordance with local waste disposal
regulation.

Note: After you use the sealing compound,
the maximum vehicle speed is 50 mph
(80 km/h) and the maximum driving distance
is 120 mi (200 km). You should inspect the
sealed tire immediately.

You can check the tire pressure any time
within the 120 mi (200 km) by performing the
steps listed previously in the Second Stage:
Checking Tire Pressure procedure.

TIRE CARE

Important Information About Low-
Profile Tires

If your vehicle is equipped with
265/40R21 tires, they are low-profile
tires. These tires and wheels are
designed to give your vehicle a sport
appearance. With low-profile tires, you
may notice an increase in road noise
and faster tire wear, depending on road
conditions and driving styles. Due to
their design, low-profile tires and wheels
are more prone to road damage from
potholes, rough or unpaved roads, car
wash rails and curb contact than
standard tires and wheels.

Note: Your vehicle's warranty does not
cover these types of damages. Extra
caution should be taken when operating
on rough roads to avoid impacts that
could cause wheel and tire damage.

Important Information About Sport
Tires and Wheels

Vehicles equipped with the optional
265/40R21 tires are designed to
enhance performance. To continue
providing this performance, extra care
must be taken when operating and
maintaining your vehicle.

These low-profile high-performance tires
are designed to optimize the driving
dynamics you expect in a sport vehicle
in both dry and wet conditions. These
tires are not optimized for off-road or
winter (snow or cold weather)
performance; and their ride, noise, and
wear characteristics are different than
non-performance tires. With low-profile
tires, you may notice an increase in road
noise and faster wear, depending on
road conditions and driving habits. Also,
because of their lower profile, the tires
are more susceptible to road damage
from potholes, rough or unpaved roads,
car wash rails, and curb contact than
standard tires and wheels.

352

Wheels and Tires

Note: Your vehicle’s warranty does not
cover these types of damages. Extra
caution should be taken when operating
on rough roads to avoid impacts that
could cause wheel and tire damage.

The optional 265/40R21 summer tires
were designed for track use and may
exhibit significantly reduced tread life
and increased tire noise compared to
the standard equipment tires under
normal driving conditions. Increasing the
front camber settings beyond the factory
settings may further accelerate tread
wear and induce tire noise.

Note:  Do not use tire chains on your
vehicle’s optional 265/40R21 tires and
wheels. The use of any type of tire chain
on these tires may damage your vehicle.
See Using Snow Chains (page 368).

Notice to Crossover Vehicle Owners

E200792

Crossover vehicles handle differently
than passenger cars in the various
driving conditions that are encountered
on streets, highways and off-road.
Crossover vehicles are not designed for
cornering at speeds as high as
passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.

Crossover vehicles have a significantly
higher rollover rate than other types of
vehicles. To reduce this risk of serious
injury or death from a rollover or other
crash you must:
•

Avoid sharp turns and abrupt
maneuvers.

•

Drive at safe speeds for the
conditions.

•

Keep tires properly inflated.

•

Never overload or improperly load
your vehicle.

•

Make sure every passenger is
properly restrained.

WARNING

In a rollover crash, an unbelted
person is significantly more likely

to die than a person wearing a seatbelt.

Information About Uniform Tire Quality
Grading

E142542

Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: Treadwear 200
Traction AA Temperature A.

These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.

Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).

U.S. Department of Transportation Tire
quality grades:  The U.S. Department of
Transportation requires Ford Motor
Company to give you the following
information about tire grades exactly as
the government has written it.

Treadwear

The treadwear grade is a comparative

rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear 1 ½ times as well on the
government course as a tire graded 100.
The relative performance of tires

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.

354

MKX (CD9) Canada/United States of America, enUSA, Edition date: 201707, Second Printing

Wheels and Tires

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.

Glossary of Tire Terminology

*Tire label: A label showing the original
equipment tire sizes, recommended
inflation pressure and the maximum
weight the vehicle can carry.

*Tire Identification Number (TIN): A
number on the sidewall of each tire
providing information about the tire
