The ISG system is to help reduce the
fuel consumption by automatically
shutting down the engine, when the
vehicle is at a standstill (i.e. red stop
light, stop sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
- The driver's seatbelt is fastened.
- The driver's door and the hood areclosed.
- The brake vacuum pressure is adequate.
- The battery is sufficiently charged.
- The outside temperature is between 14 °F and 95 °F (-10 °C and 35 °C).
- The engine coolant temperature is not too low.
- The system is not in the diagnostic mode.
Information
The ISG system is
not activated, when
the prerequisites to
activate the ISG sys-
tem are unsatisfied.
In this case, the ISG
OFF button indicator illuminates,
and the auto stop indicator ( )
illuminates in yellow on the instru-
ment cluster.
• When the above indicator remains illuminated on the instrument clus-
ter, we recommend that you have
the IGS system checked by an
authorized HYUNDAI dealer.
