Maintenance
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 spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
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 condi-
tions 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. Grade C
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
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.

Intended Outboard Sidewall
The side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light truck(LT) tire
A tire designated by its manufacturer
as primarily intended for use on light-
weight trucks or multipurpose pas-
senger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.
Load Index
An assigned number ranging from 1
to 279 that corresponds to the load
carrying capacity of a tire.
Maximum Inflation Pressure
The maximum air pressure to which
a cold tire may be inflated. The max-
imum air pressure is molded onto the
sidewall.
Maximum Load Rating
The load rating for a tire at the maxi-
mum permissible inflation pressure
for that tire.
Maximum Loaded VehicleWeight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight
The number of occupants a vehicle
is designed to seat multiplied by 150
pounds (68 kg).
Occupant Distribution
Designated seating positions.
Outward Facing Sidewall
An asymmetrical tire has a particular
side that faces outward when mount-
ed on a vehicle. The outward facing
sidewall bears white lettering or
bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.
Passenger (P-Metric) tire
A tire used on passenger cars and
some light duty trucks and multipur-
pose vehicles.
Ply
A layer of rubber-coated parallel
cords.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference between
the lamp inside and the outside tem-
perature. This is similar to the con-
densation on your windows inside
your vehicle during the rain and does-
n't indicate a problem with your vehi-
cle. If the water leaks into the lamp
bulb circuitry, have your vehicle
checked by an authorized retailer of
Genesis Branded products.

Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the Engine Start/Stop button
to the OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be hot and may burn your fin-
gers.
WARNING
OHI076038N
Do not attempt to replace or
inspect the low/high beam
(XENON bulb) due to electric
shock danger. If the low/high
beam (XENON bulb) is not work-
ing, have your vehicle checked
by an authorized retailer of
Genesis Branded products.

Maintenance
Do not use strong soap, chemi- cal detergents or hot water, and
do not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the interior.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents.
Water washing in the engine compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
Waxing
A good coat of wax provides a barri-
er between your paint and environ-
mental contamination.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.
Wiping dust or dirt off the bodywith a dry cloth will scratch the
finish.
Do not use steel wool, abrasive cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plat-
ed or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint deteriora-
tion.

Recommended SAE Viscosity Number
Always be sure to clean the area around any filler plug, drain plug, or
dipstick before checking or draining any lubricant. This is especially
important in dusty or sandy areas and when the vehicle is used on
unpaved roads. Cleaning the plug and dipstick areas will prevent dirt
and grit from entering the engine and other mechanisms that could be
damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weath-
er operating (engine start and engine oil flowability). Lower viscosity engine
oils can provide better fuel economy and cold weather performance, howev-
er, higher viscosity engine oils are required for satisfactory lubrication in hot
weather. Using oils of any viscosity other than those recommended could
result in engine damage. When choosing an oil, consider the range of temper-
ature your vehicle will be operated in before the next oil change. Proceed to
select the recommended oil viscosity from the chart.
NOTICE
*1: For better fuel economy, it is recommended to use the engine oilof a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4
(or above)). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil viscos-
ity chart.

The maintenance requirements for your new Genesis Branded Vehicle
are found in Chapter 7. As the owner, it is your responsibility to see that
all maintenance operations specified by the manufacturer are carried out
at the appropriate intervals. When the vehicle is used in severe driving
conditions, more frequent maintenance is required for some operations.
Maintenance requirements for severe operating conditions are also
included in Chapter 7.
