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.(Continued)
• When lifting a plastic-cased bat-
tery, 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 warn-
ings can result in serious bodily
injury or death.CAUTION
• When you don’t use the vehicle
for a long time in the low temper-
ature area, separate the battery
and keep it indoors.
• Always charge the battery fully to
prevent battery case damage in
low temperature area.
• If you use unauthorized electron-
ic devices, the battery may be dis-
charged. Never use unauthorized
devices.
WARNING
Separating the battery from the
vehicle should be done in an
authorized HYUNDAI dealer.

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 charg-
ing, and stop or reduce the charg-
ing 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 check-
ing the battery during charging.
• Disconnect the battery charger in
the following order.
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from
the positive battery terminal.
CAUTION- AGM battery
(if equipped)
• Absorbent Glass Matt (AGM) bat-
teries are maintenance-free and
should only be serviced by an
authorized HYUNDAI dealer. For
charging your AGM battery, use
only fully automatic battery
chargers that are specially devel-
oped for AGM batteries.
• When replacing the AGM battery,
use only the HYUNDAI genuine
battery for the ISG system.
• Do not open or remove the cap on
top of the battery. This may cause
leaks of internal electrolyte that
could result in severe injury.
• If the AGM battery is reconnected
or replaced, ISG function will not
operate immediately.
If you want to use the ISG func-
tion, the battery sensor needs to
be calibrated for approximately 4
hours with the ignition off.
