Keep batteries out of reach of children.
Batteries contain sulfuric acid that is
highly corrosive. Do not allow acid to
contact your eyes, skin, or clothing.
If acid gets into your eyes, flush your eyes
with clean water for at least 15 minutes
and get immediate medical attention. If
acid gets on your skin, thoroughly wash
the area. If you feel pain or a burning
sensation, get medical attention
immediately.
• Lift a battery with a battery carrier or with your hands on opposite corners.
When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak.
• Do not attempt to jump start your vehicle if your battery is frozen.
• NEVER attempt to recharge the battery when the vehicle’s battery cables are
connected to the battery.
• The electrical ignition switch works with high voltage. NEVER touch these
components with the Start/Stop button
in the ON or START position.

WARNING CALIFORNIA PROPOSITION 65 WARNING
Battery posts, terminals, and related
accessories contain lead and lead
compounds, chemicals known to the State of California to cause cancer, birth
defects and reproductive harm. Batteries
also contain other chemicals known to
the State of California to cause cancer.
Wash hands after handling.

• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connections clean, tight, and coated with petroleum
jelly or terminal grease.
• Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.

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, HYUNDAI
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 original tire should be repaired or
replaced as soon as possible to avoid
failure of the spare 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.

1. Manufacturer or brand name
Manufacturer or brand name is
shown.
Hyundai_CE_en_US.book Page 24

Maintenance

For example:
DOT XXXX XXXX 1523 represents that
the tire was produced in the 15th
week of 2023.
4. Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter “R” means radial ply
construction; the letter “D“ means
diagonal or bias ply construction; and
the letter “B” means belted-bias ply
construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and lbs. that can be
carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as
the factory installed tire.
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 AATEMPERATURE 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.
