Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
NOTICE
Incorrect wheel weights can
damage your vehicle’s aluminum
wheels. Use only approved wheel
weights.

A : Tread wear indicator
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before
replacing the tire.
WARNING
To reduce the risk of DEATH or
SERIOUS INJURY:

[Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, and traction.

[Always replace tires with the
same size as each tire that was
originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.

[When replacing tires (or wheels),
it is recommended to replace
the two front or two rear tires (or
wheels) as a pair. Replacing just
one tire can seriously affect your
vehicle’s handling.

[Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, Genesis Branded Vehicle
recommends that tires be
replaced after six (6) years of
normal service.

[Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging process.
Failure to follow this warning
may cause sudden tire failure,
which could lead to a loss of
vehicle control resulting in an
accident.

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.

Maintenance
Vehicle placard
A label permanently attached
to a vehicle showing the
original equipment tire size and
recommended inflation pressure.
All Season Tires
Genesis Branded Vehicle specifies
all season tires on some models to
provide good performance for use
all year round, including snowy and
icy road conditions. All season tires
are identified by ALL SEASON and/
or M+S (Mud and Snow) on the tire
sidewall. Snow tires have better
snow traction than all season tires
and may be more appropriate in
some areas.
Snow Tires
If you equip your car with snow
tires, they should be the same size
and have the same load capacity as
the original tires. Snow tires should
be installed on all four wheels;
otherwise, poor handling may result.
Snow tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not
drive faster than 75 mph (120 km/h)
when your vehicle is equipped with
snow tires.
Radial-Ply Tires
Radial-ply tires provide improved
tread life, road hazard resistance
and smoother high speed ride. The
radial-ply tires used on this vehicle
are of belted construction, and are
selected to complement the ride
and handling characteristics of
your vehicle. Radial-ply tires have
the same load carrying capacity,
as bias-ply or bias belted tires of
the same size, and use the same
recommended inflation pressure.
Mixing of radial-ply tires with
bias-ply or bias belted tires is not
recommended. Any combinations of
radial-ply and bias-ply or bias belted
tires when used on the same vehicle
will seriously deteriorate vehicle
handling. The best rule to follow
is: Identical pairs of radial-ply tires
should always be used as a set for
the front tires and a set for the rear
tires.
Longer wearing tires can be more
susceptible to irregular tread wear.
It is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
WARNING
Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause loss
of vehicle control resulting in an
accident.

Low Aspect Ratio Tires (if
equipped)
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
The side wall of a low aspect ratio
tire is shorter than the normal one.
Thus, the low-aspect wheel and
tire are easily damaged. Follow the
below instructions.

[When driving on a rough road or
driving off a road, be careful not
to damage the tires and wheels.
After driving, inspect the tires
and wheels.

[When passing over a pothole,
speed bump, manhole, or curb
stone, drive the vehicle slowly so
as not to damage the tires and
wheels.

[When there is an impact on a tire,
inspect the tire condition. Or,
contact an authorized retailer of
Genesis Branded products.

[Inspect the tire condition and
pressure every 1,800 miles (3,000
km) to prevent tire damage.

[It is difficult to recognize a tire
damage only with your eyes.
When there is a slight hint of a
tire damage, check and replace
the tire to prevent the damage
caused by air leakage.

[When a tire is damaged while
driving on a rough road, off a
road, or over obstacles, such as a
pothole, manhole, or curb stone,
your warranty does not cover the
damage.

[The tire information is specified
on the tire side wall.

High-corrosion areas
If you live in an area where your vehicle is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to occur.
For example, corrosion is accelerated
by high humidity, particularly when
temperatures are just above freezing. In
such conditions, the corrosive material is
kept in contact with the vehicle surfaces
by moisture that is slow to evaporate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still retain
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly important to keep your
vehicle clean and free of mud or
accumulations of other materials. This
applies not only to the visible surfaces
but particularly to the underside of the
vehicle.
To help prevent corrosion
Keep your vehicle clean
The best way to prevent corrosion is
to keep your vehicle clean and free of
corrosive materials. Attention to the
underside of the vehicle is particularly
important.

[If you live in a high-corrosion area —
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc.—, you should take extra
care to prevent corrosion. In winter,
hose off the underside of your vehicle
at least once a month and be sure to
clean the underside thoroughly when
winter is over.

[When cleaning underneath the
vehicle, pay particular attention to the
components under the fenders and
other areas that are hidden from view.
Do a thorough job; just dampening
the accumulated mud rather than
washing it away will accelerate
corrosion rather than prevent it. Water
under high pressure and steam are
particularly effective in removing
accumulated mud and corrosive
materials.

[When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.

Operating precautions for catalytic
converters
WARNING
The exhaust system and catalytic
system are very hot while the engine is
running or immediately after the engine
is turned off. To avoid SERIOUS INJURY
or DEATH:

[Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc. A hot exhaust system can ignite
flammable items under your vehicle.

[Keep away from the exhaust system
and catalytic converter or you may
get burned.
Also, do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle, and
do not coat the vehicle for corrosion
control. It may present a fire risk
under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:

[Use only UNLEADED FUEL for
gasoline engines.

[Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.

[Do not misuse or abuse the engine.
Examples of misuse are coasting with
the engine off and descending steep
grades in gear with the engine off.

[Do not operate the engine at high idle
speed for extended periods
(5 minutes or more).

[Do not modify or tamper with any
part of the engine or emission
control system. All inspections and
adjustments must be made by an
authorized retailer of Genesis Branded
products.

[Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.
