Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC) (if equipped)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
i
OPD056028
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.
WARNING

5-62
Driving your vehicle
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
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
- The driver's seatbelt is fastened.
- The driver's door and the hood are closed.
- The brake vacuum pressure is adequate.
- The battery is sufficiently charged.
- The outside temperature is between -10 °C and 35 °C (14 °F and 95 °F).
- The engine coolant temperature is not too low.
- The system is not in the diagnostic mode.
- The steering wheel is not steered excessively. (for dual clutch trans-
mission vehicle)
- The vehicle is driven on a steep incline. (for dual clutch transmis-
sion vehicle)
Information
• The ISG system is not activated,when the prerequisites to activate
the ISG system are unsatisfied. In
this case, the ISG OFF button indi-
cator illuminates, and the auto stop
indicator ( ) illuminates in yellow
on the instrument cluster.
• When the above indicator remains illuminated on the instrument clus-
ter, we recommend you to have the
IGS system checked by an author-
ized HYUNDAI dealer.

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 thebattery 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.
