Emergency situations
7. Connect the other end of the second
jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.
8. Start the engine of the assisting
vehicle and let it run at approximately
2,000 rpm for a few minutes. Then
start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires

qualified assistance. If the cause of your
battery discharging is not apparent,
we recommend that your vehicle be
checked by an authorized HYUNDAI
dealer.

exact reverse order you connected
them:
1. Disconnect the jumper cable from the
black, negative (-) chassis ground of
your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, negative
(-) battery/chassis ground of the

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.

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
