ISG (IDLE STOP AND GO) SYSTEM (IF EQUIPPED)

The ISG system is to reduce the fuel

consumption by automatically shutting

down the engine, when the vehicle is at

a standstill (for example, red stop light,

stop sign, and traffic jam).

The engine is automatically started

upon satisfying the starting conditions.

ESC OFF, MDPS, 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.

[A] : Battery sensor

NOTICE

The battery sensor is deactivated,

when the battery is disconnected from

the negative pole for maintenance pur-

pose.

In this case, the ISG system is limitedly

operated due to the battery sensor

deactivation. Thus, the driver needs to

take the following procedures to reacti-

vate the battery sensor after discon-

necting the battery.

• Use only the genuine HYUNDAI

ISG battery or the equivalent spefi-

cied for your vehicle for replace-

ment. If not, the ISG system may

not normally 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.

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 reac-

tivation.

Pay extreme caution not to connect any

accessories (for example, navigation

and black box) to the vehicle with the

engine in the OFF status. If not, the bat-

tery sensor may not be reactivated.
