Idle Stop And Go (ISG)
Idle Stop and Go helps reduce 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). ISG system is always active,
when the engine is running.
When the engine is automatically started
by the ISG system, warning lights (e.g.
ABS, ESC, ESC OFF, MDPS, and parking
brake warning light) may illuminate for a
few seconds if the battery voltage is low
and does not indicate a malfunction with
the ISG system.
ISG system operation
Prerequisite for activation
• The driver's seatbelt is fastened.
• The driver's door and hood are closed.
• 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 constant
speed and stops.
• The climate control system satisfies the
conditions.
• The vehicle is sufficiently warmed up.
• ISG related parts are working properly.
• The incline is gradual.
• The steering wheel is turned less than
180 degrees before the vehicle stops.
If the Auto Stop ( ) indicator is white on
the instrument cluster, the ISG system
does not meet the prerequisites above
and is not active. If the Auto Stop ( )
indicator is yellow, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Auto stop
When ISG is on, the engine stops
automatically when both of the following
occur:
1. Vehicle speed decreases to 0 mph (0
km/h) (full stop condition).
2. Brake pedal is depressed and gear is in
D (Drive) or N (Neutral).
The Auto Stop ( ) indicator illuminates in
green on the instrument cluster, when the
engine stops.
Idle stop cannot occur again until the
vehicle speed goes above 3 mph (5 km/h)
and then comes to a full stop again.
In Auto Stop mode, if the hood is opened,
ISG system is deactivated.
When the system is deactivated, the ISG
OFF button indicator illuminates and the
message, “Auto stop is Off. Shift to P or N
and start engine manually” appears on
the cluster display with a warning sound.
If this occurs, depress the brake pedal and
restart the engine manually.
