Hyundai i-30: Idle stop and go (ISG) system / To activate the ISG system
Prerequisite for activation
The ISG system operates in the following situations.
- The driver's seatbelt is fastened.
- The driver's door and the bonnet
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 transmission
vehicle)
- The vehicle is driven on a steep
incline. (for dual clutch transmission
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 indicator
illuminates, and the auto stop
indicator (
) illuminates in
yellow
on the instrument cluster. - When the above indicator remains illuminated on the instrument cluster, we recommend that you have the ISG system checked by a HYUNDAI authorised repairer.
Auto stop
To stop the engine in idle stop mode
Manual transmission vehicle
1. Decrease the vehicle speed to 3 mph (5 km/h).
2. Set the gear in N (Neutral).
3. Release the clutch pedal.
The auto stop indicator (
)
illuminates
in green on the instrument
cluster, when the engine stops.
Information
The driving speed must reach at least 6 mph (10 km/h) after an idle stop to stop the engine in idle stop mode again.
Dual clutch transmission vehicle
1. Decrease the vehicle speed to 0mph (0 km/h).
2. Shift to D (Drive) or N (Neutral).
3. Depress the brake pedal.
The auto stop indicator (
)
illuminates
in green on the instrument
cluster, when the engine stops.
Information
The driving speed must reach at least 5 mph (8 km/h) after an idle stop to stop the engine in idle stop mode again.
In auto stop mode, when the driver opens the bonnet, the ISG system will be deactivated.
When the system is deactivated:
The ISG OFF button indicator illumii nates.
The message, "Auto Stop deactivated. Start manually", appears on the LCD display with a beep sound.
At this time, restart the vehicle manually by:
Manual transmission vehicle
Depressing the clutch and brake pedal with the gear in neutral.
Dual clutch transmission vehicle
Depressing the brake pedal with the shift lever in P (Park) or N (Neutral). But for your safety, restart the vehicle in the P (Park) position.
Auto start
To restart the engine in the auto stop mode
Manual transmission vehicle
- Depress the clutch pedal with the gear in N (Neutral).
- The auto stop indicator (
)
goes
OFF on the instrument cluster,
when the engine is restarted.
Dual clutch transmission vehicle
- Release the brake pedal.
- The auto stop indicator (
)
goes
OFF on the instrument cluster,
when the engine is restarted. - When Auto Hold is activated, if you release the brake pedal, the engine will be in the auto stop state. However, if you depress the accelerator pedal, the engine will start again.
The engine is automatically restarted in the following situations.
- The fan speed of the manual climate
control system is set above
the 3rd position, with the air condition
ON.
- The fan speed of the automatic climate
control system is set above
the 6th position, with the air condition
ON.
- A certain period of time has been
elapsed with the air condition ON.
- The defroster is activated.
- The brake vacuum pressure is low.
- The battery is weak.
- The driving speed exceeds 3 mph
(5 km/h). (for manual transmission
vehicle)
- The driving speed exceeds 1.2
mph (2 km/h). (for dual clutch
transmission vehicle)
- The vehicle is shifted to P (Park) or
R (Reverse) when the brake pedal
is depressed or the Auto Hold (if
equipped with EPB) is activated.
- The door is opened or seat belt is
unfastened when the brake pedal
is depressed or Auto Hold (if
equipped with EPB) is activated.
- The EPB is pressed when the Auto
Hold is activated. (if equipped with
EPB (Electronic Parking Brake))
The auto stop indicator (
)
blinks
in green for 5 seconds on the instrument
cluster and a message "Auto
Start" will appear on the LCD display.
The auto start is temporarily deactivated in the following situations.
Manual transmission vehicle
When the gear is shifted without the clutch pedal depressed. A message "Press clutch pedal for Auto Start" will appear on the LCD display. To activate auto start, shift to neutral and depress the clutch pedal.
Dual clutch transmission vehicle
When the shift lever is shifted from N (Neutral) to R (Reverse), D (Drive) or Manual shift mode without the brake pedal depressed. A message "Press brake pedal for Auto Start" will appear on the LCD display. To activate auto start, depress the brake pedal.
Idle stop and go (ISG) system
The ISG system is to reduce the 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)...
To deactivate the ISG system, ISG system malfunction
To deactivate the ISG system
Press the ISG OFF button to deactivate
the ISG system. Then, the
ISG OFF button indicator illuminates,
and the message "Auto
Stop System Off" appears on the
LCD display...
