2015 LINCOLN MKS width

Why is the feature not available (line markings are gray) when I can see the lane markings on the road?
Staying too close to the lane marking
Driving at high speeds in curves
Previous feature activation happened within the last one second
Ambiguous lane markings (mainly in construction zones)
Rapid transition from light to dark or vice versa
Sudden offset in lane markings
ABS or AdvanceTrac activation
Camera blockage due to dirt, grime, fog, frost or water on the windshield
Driving too close to the vehicle in front of you
Transitioning between no lane markings to lane markings or vice versa
Standing water on the road
Faint lane markings (partial yellow lane markings on concrete roads)
Lane width too narrow or too wide

TIRE CARE
Information About Uniform Tire
Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The
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.

Information on P Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed rating.
The definitions of these items are
listed below. (Note that the tire size,
load index and speed rating for your
vehicle may be different from this
example.) A.
P: Indicates a tire, designated by
the Tire and Rim Association, that
may be used for service on cars,
sport utility vehicles, minivans and
light trucks. Note:
If your tire size
does not begin with a letter this may
mean it is designated by either the
European Tire and Rim Technical
Organization or the Japan Tire
Manufacturing Association.
B. 215:
Indicates the nominal width
of the tire in millimeters from
sidewall edge to sidewall edge. In
general, the larger the number, the
wider the tire.
C. 65:
Indicates the aspect ratio
which gives the tire's ratio of height
to width.
D. R:
Indicates a radial type tire.
E. 15:
Indicates the wheel or rim
diameter in inches. If you change
your wheel size, you will have to
purchase new tires to match the
new wheel diameter. F.
95:
Indicates the tire's load index.
It is an index that relates to how
much weight a tire can carry. You
may find this information in your
owner ’s manual. If not, contact a
local tire dealer.
Note: You may not find this
information on all tires because it is
not required by federal law.
G. H:
Indicates the tire's speed
rating. The speed rating denotes the
speed at which a tire is designed to
be driven for extended periods of
time under a standard condition of
load and inflation pressure. The tires
on your vehicle may operate at
different conditions for load and
inflation pressure. These speed
ratings may need to be adjusted for
the difference in conditions. The
ratings range from 81 mph (130
km/h) to 186 mph (299 km/h).
These ratings are listed in the
following chart.

A.
LT: Indicates a tire, designated
by the Tire and Rim Association,
that is intended for service on light
trucks.
B. Load Range and Load Inflation
Limits:
Indicates the tire's
load-carrying capabilities and its
inflation limits.
C. Maximum Load Dual lb (kg) at
psi (kPa) cold:
Indicates the
maximum load and tire pressure
when the tire is used as a dual;
defined as four tires on the rear axle
(a total of six or more tires on the
vehicle).
D. Maximum Load Single lb (kg)
at psi (kPa) cold:
Indicates the
maximum load and tire pressure
when the tire is used as a single;
defined as two tires (total) on the
rear axle.
Information on T Type Tires
T145/80D16 is an example of a tire
size. Note:
The temporary tire size for your
vehicle may be different from this
example. Tire Quality Grades do not
apply to this type of tire. T type tires have some additional
information beyond those of P type
tires; these differences are
described below:
A.
T:
Indicates a type of tire,
designated by the Tire and Rim
Association, that is intended for
temporary service on cars, sport
utility vehicles, minivans and light
trucks.
B. 145:
Indicates the nominal width
of the tire in millimeters from
sidewall edge to sidewall edge. In
general, the larger the number, the
wider the tire.
C. 80:
Indicates the aspect ratio
which gives the tire's ratio of height
to width. Numbers of 70 or lower
indicate a short sidewall.
D. D:
Indicates a diagonal type tire.
R:
Indicates a radial type tire.
