Maintenance
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.
Summer Tires
Genesis Branded Vehicle specifies
summer tires on some models to
provide superior performance on dry
roads. Summer tire performance is
substantially reduced in snow and
ice. Summer tires do not have the tire
traction rating M+S (Mud and Snow)
on the tire side wall. If you plan to
operate your vehicle in snowy or icy
conditions, Genesis Branded Vehicle
recommends the use of snow tires or
all season tires on all four wheels.
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; other-
wise, 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 maxi-
mum 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 radi-
al-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 combina-
tions 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 fol-
low 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.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.

Low Aspect Ratio Tires
Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
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 conse-
quently have a greater contact patch
with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
Because the sidewall of a low
aspect ratio tire is shorter than a
standard tire, the rim of the wheel
and the tire itself is more easily
susceptible to damage. Use cau-
tion when driving and follow the
guidelines below to help minimize
damage to the wheel and tire:
- When driving on a rough road or
off road, drive cautiously
because tires and wheels may be
damaged. And after driving,
inspect tires and wheels.
- When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.
- If the tire is subjected to a severe
impact, have the tire and wheel
inspected by an authorized
retailer of Genesis Branded
products.
- Inspect the tire condition and
pressure every 1,800 miles
(3,000km).• It is not easy to recognize tire
damage with your own eyes. But
if there is the slightest hint of
tire damage, have the tire
checked or replaced because
the tire damage may cause air
leakage from the tire.
• If the tire is damaged by driving
on a rough road, off road, pot-
hole, manhole, or curb stone, it
will not be covered by the war-
ranty.

Information
• It is permissible to add 3 psi to the standard tire pressure specification if cold-
er temperatures are expected soon. Tires typically loose 1 psi (7 kPa) for every
12°F temperature drop. If extreme temperature variations are expected,
recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area
above sea level. Thus, if you plan to drive a high-altitude area, check the tire
pressures in advance. If necessary, inflate them to a proper level. (Air inflation
per altitude: +2.4psi/1mile )
When replacing tires, use the same size originally supplied with the
vehicle. Using tires of a different size can damage the related parts or
not work properly.

The vehicle identification number is
the number used in registering your
car and in all legal matters pertaining
to its ownership, etc.
The number is punched on the floor
under the passenger seat. To check
the number, open the cover.
The VIN is also on a plate attached
to the top of the dashboard. The
number on the plate can easily be
seen through the windshield from
outside.The vehicle certification label
attached on the driver's side center
pillar gives the Vehicle Identification
Number.
