While driving
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.
i
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 seconds due
to the low battery voltage. However, it
does not indicate a malfunction with
the ISG system.
