and Limitations
Lane Keeping Assist malfunction
ORG3EV071192L
When Lane Keeping Assist is not working
properly, the ‘Check Lane Keeping Assist
(LKA) system’ warning message will
appear and the yellow
indicator
light will illuminate on the instrument
cluster. If this occurs, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
Limitations of Lane Keeping Assist
Lane Keeping Assist may not operate
properly or may operate unexpectedly
under the following circumstances:

[The lane is contaminated or difficult
to detect because:
- The lane markings (or road edge)
are covered with rain, snow, dirt,
oil, etc.
- The color of the lane marking (or
road edge) is not distinguishable
from the road - There are markings (or road
edges) on the road near the lane
or the markings (or road edges) on
the road look similar to the lane
markings (or road edge)
- The lane marking (or road edge) is
indistinct or damaged
- The shadow is on the lane marking
(or road edge) by a median strip,
trees, guardrail, noise barriers, etc.

[The lane number increases or
decreases, or the lane markings (or
road edges) are crossing

[There are more than two lane
markings (or road edges) on the road

[The lane markings (or road edges) are
complicated or a structure substitutes
for the lines, such as a construction
area

[There are road markings, such as
zigzag lanes, crosswalk markings and
road signs

[The lane suddenly disappears, such as
at the intersection

[The lane (or road width) is very wide
or narrow

[There is a road edge without a lane

[There is a boundary structure in the
roadway, such as a tollgate, sidewalk,
curb, etc.

[The distance to the front vehicle is
extremely short or the vehicle in front
is covering the lane marking (or road
edge)

[Rear wheel steering system (if
equipped) is disabled

Compact spare tire (if equipped)
replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is
not designed to be mounted on a
regular size wheel, and the compact
spare tire wheel is not designed for
mounting a regular size tire.
WARNING
The original tire should be repaired
or replaced as soon as possible to
avoid failure of the compact spare
tire and loss of vehicle control
resulting in an accident. The
compact spare tire is for emergency
use only. Do not operate your
vehicle over 50 mph (80 km/h)
when using the compact spare tire.
Wheel Replacement
When replacing the metal wheels
for any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire Maintenance
In addition to proper inflation,
correct wheel alignment helps to
decrease tire wear. If you find a tire
is worn unevenly, have your dealer
check the wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort
and tire life. Additionally, a tire
should always be rebalanced if it is
removed from the wheel.

Tire Sidewall Labeling
This information identifies and
describes the fundamental
characteristics of the tire and also
provides the tire identification
number (TIN) for safety standard
certification. The TIN can be used to
identify the tire in case of a recall.
ORS091058
1. Manufacturer or brand name
Manufacturer or brand name is
shown.
2. Tire size designation
A tire’s sidewall is marked with a
tire size designation. You will need
this information when selecting
replacement tires for your car.
The following explains what the
letters and numbers in the tire size
designation mean.Example tire size designation:
(These numbers are provided as
an example only; your tire size
designator could vary depending on
your vehicle.)
245/45R20 103V
245 - Tire width in millimeters.
45 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
20 - Rim diameter in inches.
103 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
V - Speed Rating Symbol. See
the speed rating chart in
this section for additional
information.
Wheel size designation
Wheels are also marked with
important information that you need
if you ever have to replace one. The
following explains what the letters
and numbers in the wheel size
designation mean.
Example wheel size designation:
8.5J X 20
8.5 - Rim width in inches.
J - Rim contour designation.
20 - Rim diameter in inches.

8. Uniform tire quality grading
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
Tread wear
The tread wear 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 one-and-a-half times (1½) 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.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest
to lowest, are AA, A, B and C. Those
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.
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.
Temperature - A, B & C
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. Grades
B and A represent higher levels of
performance on the laboratory test
wheel than the minimum required
by law.

WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and
possible sudden tire failure. This
may cause loss of vehicle control
resulting in an accident.
Tire Terminology and Definitions
Air pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory weight
This means the combined weight
of optional accessories. Some
examples of optional accessories
are automatic transmission, power
seats, and air conditioning.
Aspect ratio
The relationship of a tire’s height to
its width.
Belt
A rubber coated layer of cords that
is located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias ply tire
A pneumatic tire in which the plies are
laid at alternate angles less than 90
degrees to the centerline of the tread.
Cold tire pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT markings
A code molded into the sidewall
of a tire signifying that the tire
is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also identify
the tire manufacturer, production
plant, brand and date of production.
