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.
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
Auto stop
To stop the engine in idle stop mode
1. Decrease the vehicle speed to
0km/h.
2. Shift to D (Drive) or N (Neutral).
3. Press the brake pedal.
The auto stop indicator ( ) illumi-
nates in green on the instrument
cluster, when the engine stops.
Information

The battery sensor deactiva-
tion
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate the
battery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the IGS
system.
- The battery is weak.
- The brake vacuum pressure is low.
In those cases, we recommend you to
have the ISG system checked by an
authorized HYUNDAI dealer. • Use only the genuine HYUNDAI
ISG battery for replacement. If
not, the ISG system may not nor-
mally operate.
• Do not recharge the ISG battery
with a general battery charger. If
not, it may damage or explode
the ISG battery.
• Do not remove the battery cap. If
not, the battery electrolyte,
which is harmful to the human
body, may leak out.

to ECO mode or SPORT mode.
The mode changes, as below,
whenever the DRIVE MODE button
is pressed.
When NORMAL mode is selected,
it is not displayed on the instrument
cluster.
ECO mode
When the Drive Mode is
set to ECO mode, the
engine and transmission
control logic are changed
to maximize fuel efficiency.
• When the ECO mode is selected
by pressing the DRIVE MODE but-
ton, the ECO indicator (green

• The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
• The air conditioner performance
may be limited.
• The shift pattern of the automatic
transmission may change.
• The engine noise may get louder.
The above situations are normal
conditions when the ECO mode is
activated to improve fuel efficiency.Limitation of the ECO mode oper-
ation:
If the following conditions occur while
the ECO mode is operating, the sys-
tem operation is limited even though
there is no change in the ECO indi-
cator.
• When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.
• When driving the vehicle with the
automatic transmission or the dual
clutch transmission gear shift lever
in manual shift mode:
The system will be limited accord-
ing to the shift location.
• When the accelerator pedal is
deeply depressed for a few sec-
onds:
The system will be limited, judging
that the driver wants to speed up.SPORT mode

the driving dynamics by
automatically adjusting the
steering effort, the engine
and transmission control logic for
enhanced driver performance.
• When SPORT mode is selected by
pressing the DRIVE MODE button,
the SPORT indicator (orange
color) will illuminate.
• Whenever the engine is restarted,
the Drive Mode will revert back to

remain raised over a certain
length of time even after releas-
ing the accelerator
- Upshifts are delayed when accel-
erating
