IDLE STOP AND GO (ISG) SYSTEM
Idle Stop and Go helps reduce fuel
consumption by automatically shutting
down the engine, when the vehicle is
at a standstill (i.e. red stop light, stop
sign, and traffic jam) subject to certain
prerequisite conditions being satisfied as
listed below.
The engine is automatically started upon
satisfying the starting conditions.
ISG system is always active, when the
engine is running.
Information
When the engine is automatically started
by ISG system, warning lights (i.e. ABS,
ESC, ESC OFF, EPS, and parking brake
warning light) may illuminate for a few
seconds due to low battery voltage.
However, it does not indicate a
malfunction with ISG system.
ISG system operation
Prerequisite for activation
ISG system operates in the following
situations.
• The driver's seatbelt is fastened
• The driver's door and hood are closed
• The brake vacuum pressure is
adequate
• The battery sensor is activated and
the battery is sufficiently charged
• Outside temperature is not too low or
too high
• The vehicle is driven over a constant
speed and stops
• The climate control system satisfies
the conditions
• The vehicle is sufficiently warmed up
• ISG related parts are working properly
• The incline is gradual
• The steering wheel is turned less than
180 degrees and then the vehicle
stops
Information
If the ISG light (white) is turned on on the
instrument cluster and does not meet the
ISG system operating conditions, the ISG
system is not activated.
When the ISG light (yellow) is on while the
ISG system meets operating conditions, we
recommend that the system be inspected
by an authorized HYUNDAI dealer.

Auto stop
When ISG is on the engine will be
stopped automatically when both of the
following occurs:
1. Vehicle speed decreases to 0 mph (0
km/h) full stop condition.
2. Brake pedal is depressed and gear is
in D (Drive) or N (Neutral).
The Auto Stop (
) indicator illuminates
in green on the instrument cluster, when
the engine stops.
Information
Idle stop cannot reoccur again until the
vehicle speed goes above 3 mph (5 km/h)
and then returns again to the automatic
stop conditions as previously mentioned. In the Auto Stop mode, if the engine
hood is opened, ISG system will be
deactivated.

Forced to restart engine
The engine is automatically restarted in
the following situations.
• The brake vacuum pressure is low
• The engine has stopped for about 5
minutes
• The air conditioning is ON with the fan
speed set to a certain high level
• The front defroster is ON
• The battery is weak
• The cooling and heating performance
of the climate control system is
unsatisfactory
• The vehicle is shifted to P (Park) or R
(Reverse) when Auto Hold is activated
• The door is opened or the seatbelt
is unfastened when Auto Hold is
activated
• The EPB switch is pressed when Auto
Hold is activated
The Auto Stop (
) indicator blinks in
green for 5 seconds on the instrument
cluster when the engine is restarted.
WARNING
When the engine is in Idle Stop mode,
the engine may restart without the
driver taking any action. Before leaving
the vehicle or working on the engine
compartment, turn off the engine by
pressing the ENGINE START/STOP
button to the OFF position.
ISG malfunction
ISG system may not operate when there
is a malfunction with the ISG sensors or
ISG system.
The following will occur, when there is a
malfunction with the ISG system:
• The Auto Stop (
) indicator will
illuminate in yellow on the instrument
cluster.
• The light on the ISG OFF button will
illuminate.
We recommend that you contact an
authorized HYUNDAI dealer.
NOTICE
If the AGM battery is reconnected or
replaced, ISG system will not operate
immediately. If you want to use the
system, the battery sensor needs to be
calibrated for approximately 4 hours
with the engine off.
After calibration, turn the engine on and
off 2 or 3 times.

„„Type B
ONX4E060034
The drive mode may be selected
according to the driver’s preference or
road condition.
The system resets to be in the NORMAL
mode, when the engine is restarted.
Information
If there is a problem with the instrument
cluster, the drive mode will be in
NORMAL mode and may not change to
SPORT mode. The mode changes, as below, whenever
the DRIVE MODE button is pressed or
toggled.
NORMAL ↔ SPORT ↔ SMART ↔ SNOW
(AWD)
NORMAL - SPORT – SMART (2WD)
When NORMAL mode is selected, it is
not displayed on the instrument cluster.
NORMAL mode : NORMAL mode
provides smooth driving and comfortable
riding.
SPORT mode : SPORT mode provides
sporty but firm riding
The driving mode will be set to NORMAL
mode when the engine is restarted.
•
If it is in NORMAL/SPORT mode,
NORMAL mode will be set, when the
engine is restarted.

SPORT mode
SPORT mode provides sporty but firm riding.
In SPORT mode, the fuel
efficiency may decrease.
• When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.
• Whenever the engine is restarted,
the drive mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode.
• When SPORT mode is activated:
-The engine RPM will tend to remain
raised over a certain length of time
even after releasing the accelerator
-Upshifts are delayed when
accelerating
SMART mode
SMART mode selects the proper driving mode among ECO,
NORMAL and SPORT by judging
the driver's driving habits (i.e.
mild or dynamic) from the
brake pedal depression or the
steering wheel operation.
• Press the DRIVE MODE button to
activate SMART mode. When SMART
mode is activated, the indicator
illuminates on the instrument cluster.
• The vehicle starts in SMART mode,
when the engine was turned OFF in
SMART mode.
• SMART mode automatically controls
gear shifting patterns, engine torque,
in accordance with the driver's driving
habits.
Information
• When your vehicle drive mode
is selected to SMART mode, the
driving mode varies according to
your acceleration pedal input. When
your vehicle is in SMART mode and
your driving style is such that your
acceleration pedal input is gradual,
the drive mode will maximize fuel
efficiency. Note, however, the actual
fuel efficiency may vary according
to certain driving conditions (uphill/
downhill grade) and vehicle speed.
• When your vehicle is in SMART
mode and your driving style is more
aggressive such that your acceleration
pedal input is more abrupt, the drive
mode will change to reflect a more
SPORT driving characteristic. Note
that while you are driving this way, fuel
economy may be adversely affected.

Various driving situations, which you may
encounter in SMART mode
• The driving mode automatically
changes to ECO mode after a certain
period of time, when you gently
depress the accelerator pedal (Your
driving is categorized to be mild.).
• The driving mode automatically
changes from SMART ECO mode
to SMART COMFORT mode after a
certain period of time, when you
sharply or repetitively depress the
accelerator pedal.
• The driving mode automatically
changes to SMART COMFORT mode
with the same driving patterns, when
the vehicle starts to drive on an
upward slope of a certain angle. The
driving mode automatically returns to
SMART ECO mode, when the vehicle
enters a leveled road.
• The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
• You may still sense the engine brake
performance, even when you release
the accelerator pedal in SMART
SPORT mode. It is because your
vehicle remains to be in a lower gear
over a certain period of time for next
acceleration. Thus, it is a normal
driving situation, not indicating any
malfunction. •
The driving mode automatically
changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situations,
the driving mode sets to be either
in SMART ECO mode or in SMART
COMFORT mode.
Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indicator
illuminates in those situations.)
• The driver manually moves the shift
lever : It deactivates SMART mode.
The vehicle drives, as the driver
manually moves the shift lever.
• Cruise Control is activated : Cruise
Control may deactivate the SMART
mode. When a higher system is set
by Cruise Control, it starts to control
vehicle speed and deactivates
SMART mode. (SMART mode is not
deactivated just by activing Cruise
Control.)
• The transmission oil temperature is either
extremely low or extremely high : The
SMART mode can be active in most of
the normal driving situations. However,
an extremely high/ low transmission oil
temperature may temporarily deactivate
the SMART mode, because the
transmission condition is out of normal
operation condition.
