Maintenance
i Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE
• Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.
• When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.
• Use HYUNDAI genuine parts or the
equivalent specified for your vehicle.
Use of non-genuine parts could
damage the air flow sensor.

Filter inspection
If the vehicle is operated in the severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and replaced
earlier. When you, the owner, replace
the climate control air filter, replace it
performing the following procedure,
and be careful to avoid damaging other
components.
Replace the filter according to the
maintenance Schedule.

Blade inspection
1JBA51221JBA5122
i Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers. Common sources
of contamination are insects, tree sap,
and hot wax treatments used by some
commercial car washes. If the blades
are not wiping properly, clean both the
window and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
do not use petrol, kerosene, paint
thinner, or other solvents on or near
them.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE
To prevent damage to the wiper arms
or other components, do not attempt
to move the wipers manually.
NOTICE
The use of a non-specified wiper blade
could result in wiper malfunction and
failure.

Maintenance
For best battery service
OBI3090013OBI3090013
• 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.
• If the vehicle is not going to be used
for an extended time, disconnect the
negative terminal cable of the battery
to prevent discharge.
i Information - For batteries
marked with UPPER and
LOWER
OHYK077011OHYK077011
If your vehicle is equipped with a battery
marked with LOWER (MIN) and UPPER
(MAX) on the side, you should check the
electrolyte level.
The electrolyte level should be between
LOWER (MIN) and UPPER (MAX).
Be careful not to spill distilled (or
de-mineralized) water over the battery
surface or other adjacent components.
Also, do not overfill the battery cells.
If not, it may corrode the battery or other
components. Finally, securely close the
cell cap. However, we recommend you to
contact an authorized HYUNDAI dealer
for better battery service.
NOTICE
If the Electrolyte level is Low, add
distilled (or demineralized) water.
Never add sulfuric acid or other
electrolyte.

WARNING
Battery dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and
all other flames or sparks
away from the battery.
Hydrogen, a highly
combustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.
If any electrolyte gets into
your eyes, flush your eyes
with clean water for at least
15 minutes and get
immediate medical
attention. If electrolyte gets
on your skin, thoroughly
wash the contacted area. If
you feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection when
charging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately
disposed battery can be
harmful to the environment
and human health. Dispose
the battery according to
your local law(s) or
regulation.
The battery contains lead.
Do not dispose of it after
use. Please return the
battery to an authorized
HYUNDAI dealer to be
recycled.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak, resulting
in personal injury. Lift with a battery
carrier or with your hands on
opposite corners.
• Never attempt to recharge the
battery when the battery cables are
connected.
• The electrical ignition system works
with high voltage. Never touch these
components with the engine running
or the ignition switched on.
Failure to follow the above warnings
can result in serious bodily injury or
death.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left
on while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
• If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it at
20-30A for two hours.
WARNING
Recharging battery
When recharging the battery, observe
the following precautions:
• The battery must be removed from
the vehicle and placed in an area with
good ventilation.
• Do not allow cigarettes, sparks, or
flame near the battery.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of any
cell exceeds 49°C (120°F).
• Wear eye protection when checking
the battery during charging.
• Disconnect the battery charger in the
following order.
1. Turn off the battery charger main
switch.
