ISG (IDLE STOP AND GO) SYSTEM (IF EQUIPPED)  
Your vehicle may be equipped with the  
ISG system, which reduces fuel con-  
sumption by automatically shutting down  
the engine, when the vehicle is at a  
standstill.  
For example;  
• The gear is not engaged & clutch not  
pressed  
Left-Hand drive type  
• The vehicle speed should be over  
10km/h at least once after key starting  
or idle starting.  
(For example : red light, stop sign and  
traffic jam)  
Type A  
Type B  
• The vehicle speed should be below  
5km/h  
The engine starts automatically as soon  
as the starting conditions are met.  
• The engine coolant temperature is not  
too low  
NOTICE  
• Battery charge status is adequately  
high  
Right-Hand drive type  
When the engine automatically starts by  
the ISG system, some warning lights  
(ABS, ESP, ESP OFF or Parking brake  
warning light) may turn on for a few  
seconds.  
This happens because of low battery  
voltage. It does not mean the system is  
malfunctioning.  
• Battery temperature is between 2 to 60  
degree  
• The driver's seat belt is fastened  
• The driver's door and hood are closed.  
It could be different up to the vehicle con-  
dition.

When the engine automatically stops,  
the "AUTO STOP" indicator on the clus-  
ter panel will illuminate.

engine will start automatically. The  
"AUTO STOP" indicator on the cluster  
panel will turn off. You can continue driv-  
ing.  
ISG (Idle Stop and Go) Operation  
The ISG system is ON whenever the igni-  
tion switch is turned on.  
The engine will enter the idle stop (AUTO  
STOP) mode automatically when all of  
the essential conditions are met.
