Hyundai Elantra: Driving your vehicle / ISG (Idle Stop and Go) system
The Idle Stop and Go (ISG) system
automatically and temporarily shuts
down the engine when the vehicle is
stopped and idling to help improve
fuel efficiency and reduce exhaust gas
emissions. (i.e. red stop light, stop sign,
and traffic jam).
The engine is automatically started upon
satisfying the starting conditions.
The ISG system is always active, when
the engine is running.
Information
When the engine is automatically started
by the ISG system, some warning
lights (i.e. ABS, ESC, ESC OFF, EPS,
and parking brake warning light) may
illuminate for a few seconds due to the
low battery voltage. However, it does
not indicate a malfunction with the ISG
system.

stop and continue to depress the brake
pedal. Move the shift button into P
