Jump starting procedure

-
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
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.

First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2).
5. Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (3), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(4). Do not connect it to or near any
part that moves when the engine is
cranked.
Do not allow the jumper cables to con-
tact anything except the correct bat-
tery terminals or the correct ground.
Do not lean over the battery when
making connections.

CAUTION
Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-
minal of the discharged battery.
This can cause the discharged bat-
tery to overheat and crack, releas-
ing battery acid.
6. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, you should have your vehi-
cle checked by an authorized HYUNDAI
dealer.
