Driving your vehicle
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
Switch "ON" and "OFF" the ignition
one time. Park the vehicle for a mini-
mum of 4 hours with the hood and all
doors closed.
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
Absorbent Glass Mat (AGM) bat-
tery for replacement. If not, the
ISG system may not operate
normally.
Do not recharge the Absorbent
Glass Mat (AGM) battery with a
general battery charger. It may
damage or explode the
Absorbent Glass Mat (AGM) bat-
tery.
Do not remove the battery cap.
The battery electrolyte, which is
harmful to the human body, may
leak out.
