The ISG system helps reduce fuel
consumption and exhaust gas emis-
sions 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 hood areclosed
The brake vacuum pressure is adequate
The battery sensor is activated and the battery is sufficiently
charged
Outside temperature is not too low or too high
The vehicle is driven over a con- stant speed and stops
The climate control system satis- fies the conditions
The vehicle is sufficiently warmed up
The incline is gradual
The steering wheel is turned less than 180 degrees and then the

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 ISG system checked by an
authorized HYUNDAI dealer.
