Driving your vehicle
The ISG system is to reduce the fuel
consumption by automatically shut-
ting down the engine, when the vehi-
cle 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 are
closed.
- The brake vacuum pressure is
adequate.
- The battery is sufficiently charged.
- The outside temperature is between
-10 °C and 35 °C (14 °F and 95 °F).
- 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 system are unsatisfied. In
this case, the ISG OFF button indi-
cator illuminates, and the auto stop
indicator (
) illuminates in yellow
on the instrument cluster.
• When the above indicator remains
illuminated on the instrument clus-
ter, we recommend that you have
the ISG system checked by an
authorized HYUNDAI dealer.
