Battery Sensor Deactivation
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate the
battery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the ISG
system.
- The battery is weak.
- The brake vacuum pressure is low.
If this occurs, have the ISG system
checked by an authorized HYUNDAI
dealer.
• Use only a genuine HYUNDAI
ISG battery for replacement. If
not, the ISG system may not nor-
mally operate.
• Do not recharge the ISG battery
with a general battery charger. It
may damage or explode the ISG
battery.
• Do not remove the battery cap.
The battery electrolyte, which is
harmful to the human body, may
leak out.
